Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Only 3% of Organisations Globally are Fully Prepared for Cyber Threats
A new report released by Cisco found that only 3% of organisations globally are considered to be at a “mature” level of readiness that is needed to be resilient against today’s cyber threats. In contrast, 80% of the companies surveyed felt moderately to very confident in their ability to defend against a threat.
Nearly three-quarters of respondents expect a cyber incident to disrupt their business in the next 12 to 24 months. For many, this was based on past experience, with more than half of respondents saying that they had experienced a cyber security incident in the last 12 months, and of those, more than half of said it cost them at least $300,000. To address this, 97% of companies expect to increase their cyber security budgets in the next 12 months.

China Cyber Attacks a Reminder Beijing Poses ‘Constant and Sophisticated’ Threat to Western Cyber Security
The UK’s National Cyber Security Centre (NCSC) has now implicated a Chinese-backed hacking group, APT31, in attempts to target a group of MPs. Whilst this shows how advanced the threat from China has become, it should not be a surprise. It has been alleged that the hacking campaign targeted a broad swathe of private individuals, as well as strategically important companies and government officials. Geopolitical tensions are at an all-time high, as Conservative MP Iain Duncan Smith, one of those targeted by the campaign says, “we must now enter a new era of relations with China, dealing with the contemporary Chinese Communist party as it really is, not as we would wish it to be.”

Companies With Advanced Cyber Security Performance Deliver Nearly Four Times’ Higher Shareholder Return Than Their Peers
A recent report underscores the pivotal role of cyber security in financial performance, revealing that companies with genuinely advanced levels of cyber security maturity generate a 372% higher shareholder return compared to those with lower levels of maturity, as observed over a five-year period. Notably, companies with engaged board members and specialised risk committees achieve superior cyber security performance. Despite regulatory requirements, only 3% of UK organisations have a cyber security expert on their board, emphasising the need for greater board-level engagement in cyber risk management. Industries like healthcare and financial services lead in cyber security ratings, underscoring the correlation between regulatory environments and cyber security performance.

Hackers Hit High-Risk Individuals’ Personal Accounts
Britain’s National Cyber Security Centre (NCSC) is warning that attackers faced with well-managed corporate cyber security defences, are instead turning their efforts to compromise high-risk individuals’ devices and accounts.
A high-risk individual is anyone who has access to or influence over sensitive information. For an attacker, these individuals can present a less complex route. They already know the individual has access to the data they want, it is just a case of compromising that individual.

Cyber Security Threats in International Relations: Are We Prepared for a Digital Pearl Harbour?
Cyber security threats have reached unprecedented levels, posing significant risks to organisations and nations worldwide, with global costs predicted to soar to $10.5 trillion annually by 2025, a significant increase from $6 trillion in 2021. Recent reports from IBM Security X-Force reveal that organisations face an average of 270 cyber attacks per year, equivalent to an attack every business day, underlining the persistent nature of the threat and reinforcing the old question of ‘when’ not 'if' an organisation will get hit.
The report warns of the possibility of large-scale, coordinated attacks, akin to a “Digital Pearl Harbor,” on vital infrastructure such as power grids and financial markets, with ransomware-based attacks being identified as a major risk. The emergence of cyber warfare blurs the distinction between espionage and acts of war, underscoring the need for international standards and agreements. Despite the focus on cyber threats, many organisations have risk management gaps.

High Net Worths Urged to Improve Digital Hygiene in Fight Against Cyber Crime
High net worth individuals and their families are often targets for cyber criminals who seek to steal their money, identity, intellectual property and corporate data, and attacks are increasing. With the current state of the world, there is significant information that is publicly available. This, added to the fact that many high-net-worth individuals have lesser security controls than corporations, makes them a more lucrative target.
As these types of attacks continue to increase, it is important for individuals to ensure they are demonstrating good cyber hygiene through actions including the adoption of multi-factor authentication, limiting unnecessary social media from themselves and their family (including holidays) and understanding current tactics to be able to spot and mitigate them.

Key Lessons from Microsoft’s Password Spray Hack: Secure Every Account
Earlier this year, Microsoft discovered they had been the victim of a hack orchestrated by Russian-state hackers. The attack was not highly sophisticated; in fact, it involved simply spraying passwords into an old, inactive account. Password spraying is a simple brute force technique, which has the attacker trying the same password against multiple accounts. In this case, it was enough to be able to allow attackers to commit further exfiltration.
Picture your organisation: can you guarantee that no account is using the password “Password123”? Whilst organisations may focus on protecting privileged accounts, the attack shows that every account needs to be secured, as they are all entry points to your organisation. To combat this, organisations should look to implement robust password policies and multi-factor authentication.

Mitigating Third-Party Risk Requires a Collaborative, Thorough Approach
Mitigating third-party risk may seem daunting when considering the slew of incoming regulations coupled with the increasingly advanced tactics of cyber criminals. However, most organisations have more agency and flexibility than they think they do. Third-party risk management can be built on top of existing risk governance practices and security controls that are currently implemented in the organisation. Understanding the vendor landscape, categorising vendors based on criticality, and developing tailored governance plans are crucial steps. Contractual obligations, tailored to industry standards, play a pivotal role in ensuring security measures are upheld. Additionally, establishing a robust exit strategy is imperative to safeguard data integrity post-partnership. By fostering a culture of shared responsibility and continuous improvement, organisations can navigate the complexities of third-party risk management effectively.

IT Leaders Struggle to Keep up With Emerging Threats, as 92% of IT Leaders Say Cyber Threats Are on the Rise, 51% See AI Attacks for the First Time
A recent survey of over 800 IT and security leaders highlights the escalating threat landscape fuelled by emerging technologies, with AI-powered attacks identified as the most serious and challenging. 92% of respondents report a year-over-year increase in cyber attacks with 95% noting heightened sophistication.
Organisations reported facing AI-powered attacks (51%), deepfake technology and supply chain attacks (both 36%), cloud jacking (35%), Internet of Things (IoT) attacks and 5G network exploits (both 34%), and fileless attacks (24%). But it is not just newer attacks; organisations are still contending with prevalent attacks like phishing, malware, and ransomware. The survey found that 84% of respondents say that phishing and smishing have become more difficult to detect with the rise in popularity of AI-powered tools, revealing that AI-powered phishing is their top concern (42%) when it comes to AI security.
With so many constantly evolving threats, and with new ones being added to the mix all the time, it is becoming more and more difficult for IT leaders to keep on top of these emerging threats.

Only 5% of Boards Have Cyber Security Expertise
There is a concerning gap in cyber expertise on corporate boards, with only 5% of businesses having a cyber expert onboard, despite a direct correlation between strong cyber security and higher financial performance. Countries like France have 10% representation while Canada lags behind at just 1%. Integration of cyber experts into specialised risk committees significantly boosts cyber security performance. Furthermore, advanced security ratings translate to significantly better financial returns over three and five-year periods, underlining the pivotal role of cyber security in overall business health.

Google’s New AI Search Results Promotes Sites Pushing Malware and Scams
Earlier this month, Google began rolling out a feature called Google Search Generative Experience (SGE) in its search results, which provides AI-generated quick summaries, including site recommendations. These results, however, are pushing scams and malware. BleepingComputer found that the listed sites promoted by SGE tend to use the .online top level domain, the same HTML templates, and the same sites to perform redirects, stating “This similarity indicates that they are all part of the same SEO [search engine optimisation] poisoning campaign that allowed them to be part of the Google index.” When clicking on the site in the Google search results, visitors will go through a series of redirects until they reach a scam site. This matter highlights the need for users to stay cognisant, even when using AI to improve quality of life.

Report Calls Out Cyber Risks to Financial Sector Fuelled by AI
A recent report by the US Department of the Treasury has identified AI-driven cyber fraud as the primary concern for financial institutions. Smaller firms, in particular, struggle with AI development, which intensifies security concerns. Despite a focus on cyber security, risk management lapses are common across institutions. The report further notes that nearly a third of these institutions are yet to address the evolving tactics of threat actors, including social engineering, malvertising, and QR code phishing. More than 2 in 5 have pointed to the increasing use of generative AI for scaling and automating attacks as a lingering risk factor. The report emphasises that, even without mandates, there’s an urgent need for financial institutions to bolster their risk management and cyber security practices to counter these AI-driven threats.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Employees Think They’re Safe From Cyber Threats On Company Devices
A research launched by Menlo Security reveals increased cyber security risks posed to employees and organisations during the 2021 holiday shopping season.
The research – which surveyed 2,000 employed people in the United States and the United Kingdom – found that while employees are concerned about threats and are taking some measures to mitigate them, they often have false confidence in their security posture.
There are now more threats to corporate devices and networks than ever as hybrid work models blur the boundaries between work and home. More than half of respondents (56% US; 53% UK) reported performing non-work-related tasks – such as online shopping – on company devices.
Furthermore, the survey found that 65% of people in the US (63% UK) are doing more online holiday shopping in 2021 compared to previous years, and nearly half of respondents (48% US; 45% UK), reported shopping for gifts this holiday season on a work-issued device such as a laptop or mobile phone.
Workers are also noticing a rise in cyber threats this holiday season, with 58% of respondents in the US (48% UK) observing an increase in scams and fraudulent messages, exemplifying that threats are rampant worldwide. This is worrying many people, as the vast majority of respondents (80% US & UK) report being somewhat to very concerned about their personal data being stolen while online shopping.
However, despite workers’ recognition and concern of cyber threats, 60% of people (65% UK) still believe they’re secure from cyberthreats if they’re using a company device.

Internet Is Scrambling To Fix Log4shell, The Worst Hack In History
Massive data breaches have become so common that we’ve gotten numb to reports detailing another hack or 0-day exploit. That doesn’t reduce the risk of such events happening, as the cat-and-mouse game between security experts and hackers continues. As some vulnerabilities get fixed, others pop up requiring attention from product and service providers. The newest one has a name that will not mean anything to most people. They call the hack Log4Shell in security briefings, which doesn’t sound very scary. But the new 0-day attack is so significant that some people see it as the worst internet hack in history.
Malicious individuals are already exploiting the Log4Shell attack, which allows them to get into computer systems and servers without a password. Security experts have seen Log4Shell in action in Minecraft, the popular game that Microsoft owns. A few lines of text passed around in a chat might be enough to penetrate the defences of a target computer. The same ease of access would allow hackers to go after any computer out there using the Log4J open-sourced java-based logging utility.
https://bgr.com/tech/internet-is-scrambling-to-fix-log4shell-the-worst-hack-in-history/
Apache Log4j Flaw: A Fukushima Moment for the Cyber Security Industry
Organisations around the world will be dealing with the long-tail consequences of this vulnerability, known as Log4Shell, for years to come.
The discovery of a critical flaw in the Apache Log4j software is nothing short of a Fukushima moment for the cybersecurity industry.
Ten years ago, an earthquake and subsequent tidal wave triggered the meltdown of the Fukushima nuclear power plant that continues to plague the region today. Similarly, the early exploitation of Log4j, during which attackers will go after the low-hanging fruit exposed by the vulnerability, will evolve over time to take the form of more complex attacks on more sensitive systems that have less exposure to the internet. And, just as Fukushima brought to light significant issues with longstanding processes in place at the plant, so too does the Log4j vulnerability, known as Log4Shell, highlight two crucial practices of concern:
· How organisations capture and protect their massive troves of log data; and
· The use of open-source code libraries as the building blocks for major enterprise applications.
The paradox of Log4j: the more you log, the worse it gets
We’re discovering new apps every minute which use Log4j in one way or another. It affects not only the code you build, but also the third-party systems you have in place. Everything from the new printer you’ve bought for the office to the ticketing system you’ve just deployed is potentially affected by this flaw. Some affected systems may be on premises, others may be hosted in the cloud but no matter where they are, the flaw is likely to have an impact.

60% of UK Workers Have Been Victim of a Cyber-Attack, Yet Awareness Remains Low
There is a “dangerous” lack of awareness among UK workers towards cybersecurity, leaving businesses at risk of attacks, according to a new study by Armis. This is despite 60% of workers admitting they have fallen victim to a cyber-attack.
The nationwide survey of 2000 UK employees found that only around a quarter (27%) are aware of the associated cyber risks, while one in 10 (11%) don’t worry about them at all.
Even more worryingly, just one in five people said they paid for online security, putting businesses at high risk of attacks amid the shift to remote working during COVID-19.
The most prevalent types of attacks experienced by workers or their organisations were phishing (27%), data breaches (23%) and malware (20%).
The study also revealed growing concerns about the scale of the cyber-threats facing the UK. A large-scale cyber-attack was ranked as the fourth biggest future concern (21%) among the respondents, equal to the UK going to war. Two-fifths (40%) said they would like to see a minister for cyber security installed to ensure the issue is focused on more at a government level.
Russian-backed cyber-criminals were considered the biggest threat to the UK’s cybersecurity (20%) by the respondents, followed by financially motivated cyber-criminals (17%) and Chinese-backed cyber-criminals (16%).

Ransomware in 2022: We're All Screwed
Ransomware is now a primary threat for businesses, and with the past year or so considered the "golden era" for operators, cybersecurity experts believe this criminal enterprise will reach new heights in the future.
Kronos. Colonial Pipeline. JBS. Kaseya. These are only a handful of 2021's high-profile victims of threat groups including DarkSide, REvil, and BlackMatter.
According to Kela's analysis of dark web forum activity, the "perfect" prospective ransomware victim in the US will have a minimum annual revenue of $100 million and preferred access purchases include domain admin rights, as well as entry into Remote Desktop Protocol (RDP) and Virtual Private Network (VPN) services.
Over the past few years, we've seen ransomware operators evolve from disorganised splinter groups and individuals to highly sophisticated operations, with separate teams collaborating to target everything from SMBs to software supply chains.
Ransomware infection is no longer an end goal of a cyberattack. Instead, malware families in this arena -- including WannaCry, NotPetya, Ryuk, Cerber, and Cryptolocker -- can be one component of attacks designed to elicit a blackmail payment from a victim organisation.

Attacks on UK Firms Increase Five-Fold During Pandemic
Attacks on UK firms surged five-fold during the pandemic and now cost way more than the global average, according to Accenture.
The global consultancy polled 500 UK executives to compile its State of Cybersecurity Resilience 2021 study.
It found that large organisations experienced 885 attempted cyber-attacks in 2020 – up from 156 the previous year and more than triple the global average of 270.
They’re also more expensive than elsewhere. Accenture calculated that incidents and breaches cost over £1.3m a year – £350,000 more than the global average.
Over 80% of respondents said the cost of staying ahead of cyber-criminals is unsustainable, a fifth more than the previous year, and a quarter said they’ve been forced to increase cybersecurity budgets by 10% or more.
Worryingly, supply chain attacks accounted for 64% of breaches in the UK last year, up by a quarter (26%) from the previous year.

The Log4J Software Flaw Is ‘Christmas Come Early’ for Cyber Criminals
Researchers have just identified a security flaw in a software program called Log4J, widely used by a host of private, commercial and government entities to record details ranging from usernames and passwords to credit card transactions. Since the glitch was found last weekend, the cybersecurity community has been scrambling to protect applications, services, infrastructure and even Internet of Things devices from criminals—who are already taking advantage of the vulnerability.
“For cybercriminals this is Christmas come early, because the sky’s the limit,” says Theresa Payton, a former White House chief information officer and the CEO of Fortalice Solutions, a cybersecurity consulting company. “They’re really only limited by their imagination, their technical know-how and their own ability to exploit this flaw.” Payton spoke with Scientific American about what Log4J does, how criminals can use its newly discovered weakness, and what it will take to repair the problem.
Why Cloud Storage Isn't Immune to Ransomware
Ransomware is the flavour of the month for cybercriminals. The FBI reports that ransomware attacks rose 20% and losses almost tripled in 2020. And our increased use of the cloud may have played a part in that spike. A survey of CISOs conducted by IDC earlier this year found that 98% of their companies suffered at least one cloud data breach in the previous 18 months as opposed to 79% last year, and numbers got worse the more exposure they had to the cloud.
Organisations now use hundreds of cloud-based apps, which adds thousands of new identities logging in to their systems. This opens almost unlimited possibilities for hackers. Even if cloud vendors have their own identity and access management controls, vulnerabilities will emerge. In fact, recent research into cloud security found that over 70% of organisations had machines open to the public that were linked to identities whose permissions were vulnerable, under the right conditions, to being exploited to launch ransomware attacks.
A number of reasons could explain why security falls through the cracks of many cloud systems, and leaves them more vulnerable to ransomware attacks.

400 Banks’ Customers Targeted with Anubis Trojan
Customers of Chase, Wells Fargo, Bank of America and Capital One, along with nearly 400 other financial institutions, are being targeted by a malicious app disguised to look like the official account management platform for French telecom company Orange S.A.
Researchers say this is just the beginning.
Once downloaded, the malware – a variant of banking trojan Anubis – steals the user’s personal data to rip them off, researchers at Lookout warned in a new report. And it’s not just customers of big banks at risk, the researchers added: Virtual payment platforms and crypto wallets are also being targeted.
“As a banking trojan malware, Anubis’ goal is to collect significant data about the victim from their mobile device for financial gain,” the Lookout report said. “This is done by intercepting SMSs, keylogging, file exfiltration, screen monitoring, GPS data collection and abuse of the device’s accessibility services.”

Sites Hacked With Credit Card Stealers Undetected For Months
Threat actors are gearing up for the holidays with credit card skimming attacks remaining undetected for months as payment information is stolen from customers.
Magecart skimming is an attack that involves the injection of malicious JavaScript code on a target website, which runs when the visitor is at the checkout page.
The code can steal payment details such as credit card number, holder name, addresses, and CVV, and send them to the actor.
Threat actors may then use this information for purchasing goods online or sold to other actors on underground forums and dark web marketplaces known as "carding" sites.

Cyber Briefing 23 October 2020: Ransomware Continues to Evolve; Infected IoT Up 100%; Brute Force Attacks Up with more Open RDP Ports; 40% Unsure on Mobile Phishing; Most Imitated Phishing Brands
Cyber Briefing 23 October 2020: Ransomware Variants Evolve as Crooks Chase Bigger Paydays; Infected IoT Surges 100% in a Year; Brute Force Attacks Up Due To More Open RDP Ports; 40% of Users Not Sure What Mobile Phishing Is; Microsoft Most Imitated Phishing Brand Q3 2020; DDoS Triples as Ransoms Re-Emerge; Exploited Chrome Bug Fixed; WordPress Forces Security Update; The Most Worrying Vulns Around Today
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities and cyber related news from the last week.
Threats
Ransomware
This week has been busy with ransomware related news, including new charges against Russian state-sponsored hackers and numerous attacks against well-known organisations.
In 2017, there was an attack utilizing the NotPetya ransomware to destroy data on systems worldwide. This week, the US govt indicted six Russian intelligence operatives [source], known to be part of the notorious 'Sandworm' group, for hacking operations, including NotPetya.
Ransomware variants continue to evolve as crooks chase bigger paydays
The number of ransomware attacks which threaten to leak stolen data if the victim doesn't pay a ransom to get their encrypted files and servers back is growing – and this is being reflected in the changing nature of the cyber criminal market.
Analysis by cyber security researchers found that over the last three months – between July and September - 80 percent of ransomware attacks combined with data dumps were associated with four families of ransomware – Maze, Sodinokibi, Conti and Netwalker.
The period from April to June saw just three ransomware families account for 80 percent of alerts – DoppelPaymer, Maze and Sodinokibi.
The way DoppelPayer has dropped off and how Conti and NetWalker have suddenly emerged some of the most prolific threats shows how the ransomware space continues to evolve, partly because of how successful it has already become for the crooks behind it. [source]
Why this matters:
Maze was the first major family of ransomware to add threats of data breaches to their ransom demands and other ransomware operators have taken note – and stolen the additional extortion tactic.
There is an inherent competitive nature that has befallen the ransomware landscape. The saturated ransomware market pushes ransomware developers to cut through the noise and gain the best ransomware title and this drives more affiliates to carry out their work and, thus, more successful attacks to reach their goal: to make as much money as possible.
DoppelPaymer's activity has dropped over the last few months – although it still remains active - enabling Conti and NetWalker to grab a larger slice of the pie.
Notable ransomware victims of the last week
French IT giant Sopra Steria hit by Ryuk ransomware
French IT services giant Sopra Steria suffered a cyber attack on October 20th, 2020, that reportedly encrypted portions of their network with the Ryuk ransomware.
Sopra Steria is a European information technology company with 46,000 employees in 25 countries worldwide. The company provides a wide range of IT services, including consulting, systems integration, and software development.
The firm has said that the attack has hit all geographies where they operate and have said it will take them several weeks to recover.
Numerous sources have confirmed that it was Ryuk ransomware threat actors who were behind the attack. This hacking group is known for its TrickBot and BazarLoader infections that allow threat actors to access a compromised network and deploy the Ryuk or Conti ransomware infections.
BazarLoader is increasingly being used in Ryuk attacks against high-value targets due to its stealthy nature and is less detected than TrickBot by security software.
When installed, BazarLoader will allow threat actors to remotely access the victim's computer and use it to compromise the rest of the network.
After gaining access to a Windows domain controller, the attackers then deploy the Ryuk ransomware on the network to encrypt all of its devices, as illustrated in the diagram above. [Source1] [source2]
The Nefilim ransomware operators have posted a long list of files that appear to belong to Italian eyewear and eyecare giant Luxottica.
Luxottica Group S.p.A. is an Italian eyewear conglomerate and the world’s largest company in the eyewear industry (which owns brands including LensCrafters, Sunglass Hut, Apex by Sunglass Hut, Pearle Vision, Target Optical, Eyemed vision care plan, and Glasses.com. Its best known brands are Ray-Ban, Persol, and Oakley) and employs over 80,000 people and generated 9.4 billion in revenue for 2019.
The company was hit by a cyber attack and some of the web sites operated by the company were not reachable, including Ray-Ban, Sunglass Hut, LensCrafters, EyeMed, and Pearle Vision.
Reports indicate that the firm was using a Citrix ADX controller device vulnerable to a critical vulnerability and it is believed that a threat actor or actors exploited the above flaw to infect the systems at the company with ransomware. This appears to have subsequently confirmed with Nefilim ransomware operators having posted a long list of files that appear to belong to Luxottica. [source]
Why this matters:
The analysis of the leaked files revealed that they contain confidential information regarding the recruitment process, professional resumes, and info about the internal structures of the Group’s human resource department. The ransomware operators also published a message which accuses Luxottica of having failed the properly manage the attack.
In the past months, the number of ransomware attacks surged, numerous ransomware gangs made the headlines targeting organisations worldwide and threatening victims with releasing the stolen data if the ransom was not paid.
Extortion is the new thing in cyber crime right now, more so than in the past. Companies cannot hide the cyber attack anymore. Now it’s more about how to manage the breach from the communication perspective. Defending companies from these types of attacks becomes even more strategic: data leak damages can generate tremendous amount of costs for companies worldwide.
Other notable ransomware victims this week include:
Barnes & Noble hit by Egregor ransomware, strange data leaked [source]
Montreal's STM public transport system hit by ransomware attack [source]
WastedLocker ransomware hits US-based ski and golf resort operator Boyne Resorts (WastedLocker was the same one used in the attack on Garmin in July) [source]
Other Threats
Infected IoT Device Numbers Surge 100% in a Year
The volume of infected Internet of Things (IoT) devices globally has soared by 100% over the past year, according to new data from Nokia.
It revealed that infected IoT devices now comprise nearly a third (32.7%) of the total number of devices, up from 16.2% in the 2019 report.
Nokia argued that infection rates for connected devices depend dramatically upon the visibility of the devices on the internet.
In networks where devices are routinely assigned public facing internet IP addresses there is a higher infection rate. In networks where carrier grade NAT is used, the infection rate is considerably reduced, because the vulnerable devices are not visible to network scanning.
With the introduction of 5G well underway, it is expected that not only the number of IoT devices will increase dramatically, but also the share of IoT devices accessible directly from the internet will increase as well, and rates of infection rising accordingly. [source]
Brute force attacks increase due to more open RDP ports
While leaving your back door open while you are working from home may be something you do without giving it a second thought, having unnecessary ports open on your computer or on your corporate network is a security risk that is sometimes underestimated. That’s because an open port can be subject to brute force attacks.
A brute force attack is where an attacker tries every way he can think of to get in. Including throwing the kitchen sink at it. In cases where the method they are trying is to get logged in to your system, they will try endless combinations of usernames and passwords until a combination works.
Brute force attacks are usually automated, so it doesn’t cost the attacker a lot of time or energy. Certainly not as much as individually trying to figure out how to access a remote system. Based on a port number or another system specific property, the attacker picks the target and the method and then sets his brute force application in motion. He can then move on to the next target and will get notified when one of the systems has swallowed the hook.
RDP attacks are one of the main entry points when it comes to targeted ransomware operations. To increase effectiveness, ransomware attacks are getting more targeted and one of the primary attack vectors is the Remote Desktop Protocol (RDP). Remote desktop is exactly what the name implies, an option to remotely control a computer system. It almost feels as if you were actually sitting behind that computer. Which is exactly what makes an attacker with RDP access so dangerous. [source]
Why this matters:
Because of the current pandemic, many people are working from home and may be doing so for a while to come. Working from home has the side effect of more RDP ports being opened. Not only to enable the workforce to access company resources from home, but also to enable IT staff to troubleshoot problems on the workers’ devices. A lot of enterprises rely on tech support teams using RDP to troubleshoot problems on employee’s systems.
But ransomware, although prevalent, is not the only reason for these types of attacks. Cyber criminals can also install keyloggers or other spyware on target systems to learn more about the organization they have breached. Other possible objectives might be data theft, espionage, or extortion.
Phishing
Two in five employees are not sure what a mobile phishing attack is
The COVID-19 pandemic has clearly changed the way people work and accelerated the already growing remote work trend. This has also created new security challenges for IT departments, as employees increasingly use their own personal devices to access corporate data and services.
These changes, where employees, IT infrastructures, and customers are everywhere – has led to employees not prioritising security in their new world of work, and the current distributed remote work environment has also triggered a new threat landscape, with malicious actors increasingly targeting mobile devices with phishing attacks.
A new study looking at the impact that lockdown has had on employees working habits polled 1,200 workers across the US, UK, France, Germany, Belgium, Netherlands, Australia, and New Zealand showed that many employees were unaware of how to identify and avoid a phishing attack, and over two in five (43%) of employees are not even sure what a phishing attack is. [source]
Microsoft is Most Imitated Brand for Phishing Attempts in Q3 2020
The latest Check Point ‘Q3 Brand Phishing Report’, highlighting the brands that hackers imitated the most to lure people into giving up personal data, reveals the brands which were most frequently imitated by criminals in their attempts to steal individuals’ personal information or payment credentials during July, August and September.
In Q3, Microsoft was the most frequently targeted brand by cyber criminals, soaring from fifth place (relating to 7% of all brand phishing attempted globally in Q2 of 2020) to the top of the ranking. 19% of all brand phishing attempts related to the technology giant, as threat actors sought to capitalise on large numbers of employees still working remotely during the Covid-19 pandemic. For the first time in 2020, DHL entered the top 10 rankings, taking the second spot with 9% of all phishing attempts related to the company. [source]
Top phishing brands in Q3 2020
Microsoft (19%)
DHL (9%)
Google (9%)
PayPal (6%)
Netflix (6%)
Facebook (5%)
Apple (5%)
Whatsapp (5%)
Amazon (4%)
Instagram (4%)
Phishing Lures Shifting from COVID-19 updates to Job Opportunities
Researchers are seeing a pivot in the spear-phishing and phishing lures used by cybercriminals, to entice potential job candidates as businesses start to open up following the pandemic.
Cyber criminals cashed in on the surge of COVID-19 earlier this year, with email lures purporting to be from healthcare professionals offering more information about the pandemic. However, as the year moves forward, bad actors are continuing to swap up their attacks and researchers are now seeing ongoing email based attacks that tap into new job opportunities as businesses start to open up. [source]
Denial of Service Attacks
DDoS (Distributed Denial of Service) Attacks Triple in Size as Ransom Demands Re-Emerge
The last quarter of 2020 has seen a wave of web application attacks which have used ransom letters to target businesses across a number of industries.
According to research from Akamai, the largest of these attacks sent over 200Gbps of traffic at their targets as part of a sustained campaign of higher Bits Per Second (BPS) and Packets Per Second (PPS) than similar attacks had displayed a few weeks prior.
Prior to August most of these attacks were targeting the gaming industry but since then these attacks abruptly swung to financial organisations, and later in the cycle, multiple other verticals.
Akamai explained that none of the vectors involved in these series of attacks were new, as most of the traffic was generated by reflectors and systems that were used to amplify traffic. However, multiple organisations began to receive targeted emails with threats of DDoS attacks, where this would be launched unless a ransom amount was paid. A small DDoS would be made against the company to show that the attackers were serious, and then there was a threat of a 1Tbps attack if payment was not made.
Many extortion DDoS campaigns start as a threat letter, and never progress beyond that point but this this campaign has seen frequent ‘sample’ attacks that prove to the target that criminals have the capability to make life difficult.
Many of the extortion emails ended up being caught by spam filters, and not all targets are willing to admit they’ve received an email from the attackers.
Why this matters:
This extortion DDoS campaign is not over and the criminals behind this campaign are changing and evolving their attacks in order to throw off defenders and the law enforcement agencies that are working to track them down.
Vulnerabilities
New Google Chrome version fixes actively exploited zero-day bug
Google released Chrome 86.0.4240.111 this week to address five security vulnerabilities, one of which is being actively exploited.
The announcement from Google stated they they were aware of reports that an exploit for CVE-2020-15999 exists in the wild.
This new version of Chrome started rolling out to the entire userbase. Users on Windows, Mac, and Linux desktop users can upgrade to Chrome 86 by going to Settings -> Help -> About Google Chrome.
The Google Chrome web browser will then automatically check for the new update and install it when available.
Adobe releases another out-of-band patch, squashing critical bugs across creative software
Adobe has released a second out-of-band security update to patch critical vulnerabilities across numerous software products.
The patch, released outside of the tech giant's typical monthly security cycle, impacts Adobe Illustrator, Dreamweaver, Marketo, Animate, After Effects, Photoshop, Premiere Pro, Media Encoder, InDesign, and the Creative Cloud desktop application on Windows and macOS machines.
The vulnerabilities across the different products variously could result in privilege escalation, cross-site scripting (XSS), which could be weaponised to deploy malicious JavaScript in a browser session, or otherwise could result in arbitrary code execution.
Last week, Adobe released a separate set of out-of-band security fixes impacting the Magento platform. On October 15, Adobe said the patch resolved nine vulnerabilities, eight of which are critical -- including a bug that could be abused to tamper with Magento customer lists. [source]
WordPress deploys forced security update for dangerous bug in popular plugin
The WordPress security team has taken a rare step last week and used a lesser-known internal capability to forcibly push a security update for a popular plugin called Loginizer, which provides security enhancements for the WordPress login page, but that was found to contain a dangerous SQL injection bug that could have allowed hackers to take over WordPress sites running older versions of the plugin. [source]
Why this matters:
Remote attackers to run code against the WordPress database — in what is referred to as an unauthenticated SQL injection attack.
These are the most worrying vulnerabilities around today
Failure to patch once again leaves organisations open to attacks
The US National Security Agency (NSA) has published a new cyber security advisory in which it details 25 of the most dangerous vulnerabilities actively being exploited in the wild by Chinese state-sponsored hackers and other cyber criminals.
Unlike zero-day vulnerabilities where hardware and software makers have yet to release a patch, all of the vulnerabilities in the NSA's advisory are well-known and patches have been made available to download from their vendors. However, the problem lies in the fact that organisations have yet to patch their systems, leaving them vulnerable to potential exploits and attacks.
The NSA provided further details on the nature of the vulnerabilities in its advisory while urging organisations to patch them immediately.
Most of the vulnerabilities listed below can be exploited to gain initial access to victim networks using products that are directly accessible from the Internet and act as gateways to internal networks. The majority of the products are either for remote access or for external web services and should be prioritised for immediate patching. The full list can be found here.
The first bug in the list, tracked as CVE-2019-11510, relates to Pulse Secure VPN servers and how an unauthenticated remote attacker can expose keys or passwords by sending a specially crafted URI to perform an arbitrary file reading vulnerability.
Another notable bug from the list, tracked as CVE-2020-5902, affects the Traffic Management User Interface (TMUI) of F5 BIG-IP proxies and load balancers and it is vulnerable to a Remote Code Execution (RCE) vulnerability that if exploited, could allow a remote attacker to take over an entire BIG-IP device.
The Citrix Application Delivery Controller (ADC) and Gateway systems are vulnerable to a directory traversal bug, tracked as CVE-2019-19781, that can lead to remote code execution where an attacker does not need to possess valid credentials for the device.
The advisory also mentions BlueKeep, SigRed, Netlogon, CurveBall and other more well-known vulnerabilities.
To avoid falling victim to any potential attacks exploiting these vulnerabilities, the NSA recommends that organisations keep their systems and products updated and patched as soon as possible after vendors release them. [source]
Miscellaneous Cyber News of the Weeks
Hackers Can Clone Millions of Toyota, Hyundai, and Kia Keys
Owners of cars with keyless start systems have learned to worry about so-called relay attacks, in which hackers exploit radio-enabled keys to steal vehicles without leaving a trace. Now it turns out that many millions of other cars that use chip-enabled mechanical keys are also vulnerable to high-tech theft. A few cryptographic flaws combined with a little old-fashioned hot-wiring—or even a well-placed screwdriver—lets hackers clone those keys and drive away in seconds.
Researchers this week revealed new vulnerabilities in the encryption systems used by immobilisers, the radio-enabled devices inside of cars that communicate at close range with a key fob to unlock the car's ignition and allow it to start. Specifically, they found problems in how Toyota, Hyundai, and Kia implement their encryption system. A hacker who swipes a relatively inexpensive RFID reader/transmitter device near the key fob of any affected car can gain enough information to derive its secret cryptographic value. That, in turn, would allow the attacker to spoof the device to impersonate the key inside the car, disabling the immobiliser and letting them start the engine.
The researchers say the affected car models include the Toyota Camry, Corolla, and RAV4; the Kia Optima, Soul, and Rio; and the Hyundai I10, I20, and I40, amongst others. [source]
