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
UK Companies Banned from Paying Ransomware Hackers After Attacks on Royal Mail and Guardian
British companies have been banned from paying ransomware hackers after a spate of attacks on businesses including Royal Mail and the Guardian newspaper.
UK Foreign Secretary James Cleverly on Thursday unveiled sanctions on seven Russian hackers linked to a gang called Conti, effectively banning any payments to the group.
Thursday’s sanctions are the first of their kind to be specifically targeted against Russian ransomware gang members.
The actions follow a spate of high-profile attacks on businesses and amid warnings from GCHQ that Russian and Iranian hackers are stepping up actions in Britain.
Fraud Set to Be Upgraded as a Threat to National Security
Fraud is to be reclassified as a threat to national security under UK government plans that will force police chiefs to devote more officers to solving the crime.
It will be elevated to the same status as terrorism, with chief constables mandated to increase resources and combine capabilities in a new effort to combat a fraud epidemic that now accounts for 30 per cent of all crime.
It will be added to the strategic policing requirement, which means that forces will be required by ministers to treat fraud as a major priority alongside not only terrorism, but also public disorder, civil emergencies, serious and organised crime, cyber attacks and child sexual abuse.

98% of Attacks are Not Reported by Employees to their Employers
Cyber attackers are increasingly using social engineering tactics to lure employees into opening malicious emails in an attempt to trick them into providing login credentials, updating bank account information and paying fraudulent invoices. Worryingly, research conducted by security provider Abnormal has found that 98% of attacks on organisations are not reported to the organisation’s security team. In addition to this, the report found that the volume of business email compromise attacks are spiking, growing by 175% over the past two years. The report also found that nearly two-thirds of large enterprises experiencing a supply chain compromise attack in the second half of 2022.
UK Second Most Targeted Nation Behind America for Ransomware
Security research team Kraken Labs released their report earlier this week, which found that of the 101 different countries that registered victims of ransomware, the UK had registered the second highest number of victims behind the US. Currently, there are over 60 ransomware groups, with the top 3 accounting for a third of all ransomware attacks.
Financial Institutions are Suffering from Increasingly Sophisticated Cyber Attacks
This week security provider Contrast Security released its Cyber Bank Heists report, an annual report that exposes cyber security threats facing the financial sector. The report warns financial institutions that security must be a top-of-mind issue amid rising geopolitical tensions, increased destructive attacks utilising wipers and a record-breaking year of zero-day exploits. The report involved a series of interviews with financial sector security leaders and found some notable results. Some of the results include 64% of leaders seeing an increase in application attacks, 72% of respondents planning to increase investment in application security in 2023, 60% of respondents falling victim to destructive attacks and 50% of organisations detecting campaigns which aimed to steal non-public market information.
An Email Attack Can End Up Costing You Over $1 Million
According to a report by security provider Barracuda Network, 75% of organisations had fallen victim to at least one successful email attack in the last 12 months, with those affected facing potential costs of over $1 million for their most expensive attack. The fallout from an email security attack can be significant, with the report finding 44% of those hit had faced significant downtime and business disruption. Additionally financial services greatly impacted by the loss of valuable data (59%) and payments made to attackers (51%). When it came to organisations preparation, 30% felt underprepared when dealing with account takeover and 28% felt unprepared for dealing with business email compromise.

Cyber Crime Shows No Signs of Slowing Down
Global risks from population pressures and climate change to political conflicts and industrial supply chain challenges characterised 2022. Cyber criminals used this turmoil to exploit these trending topics, including significant events, public affairs, social causes, and anywhere else opportunity appeared. According to security researchers at Zscaler TheatLabz, 2023 will see a rise in Crime-as-a-service (CaaS), supply chains will be bigger targets than ever, there will be a greater need for defence in depth as endpoint protection will not be enough and finally, there will be a decrease in the time between initial compromise and the final stage of an attack.

Surge of Swatting Attacks Targets Corporate Executive and Board Members
Swatting is the act of deceiving an emergency service with the purpose of the service then sending an emergency response, often armed, to a targeted persons address. Security provider Black Cloak has found that swatting incidents are now beginning to target C-suite executives and corporate board members, with the number of incidents increasing over the last few months. Malicious actors are using information from the dark web, company websites and property records to construct their swatting attacks.
Phishing Surges Ahead, as ChatGPT and Artificial Intelligence Loom
Artificial Intelligence (AI) is making it easier for threat actors to create sophisticated and malicious email campaigns. In their report, security provider Vade found that Q4 of 2022 saw a 36% volume increase in phishing campaigns compared to the previous quarter, with over 278.3 million unique phishing emails in that period. The researchers found in particular, new AI tools such as ChatGPT had made it easy for anyone, including those with limited skills, to conduct a sophisticated phishing campaign. Furthermore, the ability of ChatGPT to tailor phishing to different languages is an area for concern.

Pro-Russian Hacktivist Group is Only Getting Started, Experts Warn
A pro-Russian hacktivist group's low-level distributed denial-of-service (DDoS) attacks on US critical infrastructure could be a precursor to more serious cyber attacks, health care and security officials warned this week. A DDoS attack involves overwhelming a targeted service, service or network with traffic in an attempt to disrupt it. Earlier this week Killnet, a politically motivated Russian hacking group, overloaded and took down some US healthcare organisations. The attack came after threatening western healthcare organisations for the continued NATO support of Ukraine.

Crypto Investors Lost Nearly $4 Billion to Hackers in 2022
Last year marked the worst year on record for cryptocurrency hacks, according to analytic firm Chainalysis’ latest report. According to the report, hackers stole $3.8 billion in 2022, up from $3.3 billion the previous year. De-centralised finance products, which are products that have no requirement for an intermediary or middle-man accounted for about 82% of all crypto stolen.
PayPal and Twitter Abused in Turkey Relief Donation Scams
Scammers are now exploiting the ongoing humanitarian crisis in Turkey and Syria. This time, stealing donations by abusing legitimate platforms such as PayPal and Twitter. It has been identified that multiple scams are running which call for fundraising, linking the victim to a legitimate PayPal site. The money however, is kept by the scammer.
Mysterious Leak of Booking.com Reservation Data is Being Used to Scam Customers
For almost 5 years, Booking.com customers have been on the receiving end of a continuous series of scams that demonstrate criminals have obtained travel plans amongst other personally identifiable information that were provided to Booking.com. The scams have involved users receiving fake emails purporting to be from Booking.com with genuine travel details that victims had provided. These emails contain links to malicious URL’s that look nearly identical to the Booking.com website. These then display the victim’s expected travel information, requiring them to input their card details. Some of the scams have developed and involve scammers sending WhatsApp messages after payment has been made, purporting to be from hotels which have been booked by the victims.

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
Cyber Criminals Shifting Focus: IT Sector Most Targeted In 2021
Darktrace reported that the IT and communications sector was globally the most targeted industry by cybercriminals in 2021.
Darktrace’s data is developed by ‘early indicator analysis’ that looks at the breadcrumbs of potential cyber-attacks at several stages before they are attributed to any particular actor and before they escalate into a full-blown crisis. Findings show that its artificial intelligence autonomously interrupted an average of 150,000 threats per week against the sector in 2021.
The IT and communications sector includes telecommunications providers, software developers, and managed security service providers, amongst others. There was also a growing trend of hackers targeting backup servers in an attempt to deliberately disable or corrupt backup files by deleting a single index file that would render all backups inaccessible. Attackers could then launch ransomware attacks against the clients of the backup vendor, preventing recovery and forcing payment.
In 2020, the most attacked industry was the financial and insurance sector, showing that cyber-criminals have shifted their focus over the last 12 months.
Over the last 12 months, it is clear that attackers are relentlessly trying to access the networks of trusted suppliers in the IT and communications sector. Quite simply, it is a better return on investment than, for example, going after one company in the financial services sector. SolarWinds and Kaseya are just two well-known and recent examples of this. Sadly, there is likely to be more in the near term.
The findings of this research mark one year since the compromise of US software company SolarWinds rattled the security industry. This landmark supply-chain attack made thousands of organisations vulnerable to infiltration by inserting malicious code into the Orion system. Over the last 12 months, there has been a continued spate of attacks against the IT and communications sector, including the high-profile attacks on Kaseya and Gitlab.

New Ransomware Variants Flourish Amid Law Enforcement Actions
Ransomware groups continue to evolve their tactics and techniques to deploy file-encrypting malware on compromised systems, notwithstanding law enforcement's disruptive actions against the cyber crime gangs to prevent them from victimizing additional companies.
"Be it due to law enforcement, infighting amongst groups or people abandoning variants altogether, the RaaS [ransomware-as-a-service] groups dominating the ecosystem at this point in time are completely different than just a few months ago," Intel 471 researchers said in a report published this month. "Yet, even with the shift in the variants, ransomware incidents as a whole are still on the rise."
Sweeping law enforcement operations undertaken by government agencies in recent months have brought about rapid shifts in the RaaS landscape and turned the tables on ransomware syndicates like Avaddon, BlackMatter, Cl0p, DarkSide, Egregor, and REvil, forcing the actors to slow down or shut down their businesses altogether.
https://thehackernews.com/2021/12/new-ransomware-variants-flourish-amid.html
93% of Tested Networks Vulnerable to Breach, Pen Testers Find
Data from dozens of penetration tests and security assessments suggest nearly every organisation can be infiltrated by cyber attackers.
The vast majority of businesses can be compromised within a month by a motivated attacker using common techniques, such as compromising credential, exploiting known vulnerabilities in software and Web applications, or taking advantage of configuration flaws, according to an analysis of security assessments by Positive Technologies.
In 93% of cases, an external attacker could breach a target company's network and gain access to local devices and systems, the company's security service professionals found. In 71% of cases, the attacker could affect the businesses in a way deemed "unacceptable." For example, every bank tested by the security firm could be attacked in a way that disrupted business processes and reduced the quality of their service.

A new Dridex malware phishing campaign is using fake employee termination emails as a lure to open a malicious Excel document, which then trolls the victim with a season's greeting message.
Dridex is a banking malware spread through malicious emails that was initially developed to steal online banking credentials. Over time, the developers evolved the malware to use different modules that provide additional malicious behaviour, such as installing other malware payloads, providing remote access to threat actors, or spreading to other devices on the network.
This malware was created by a hacking group known as Evil Corp, which is behind various ransomware operations, such as BitPaymer, DoppelPaymer, WastedLocker variants, and Grief. Due to this, Dridex infections are known to lead to ransomware attacks on compromised networks.
More Than 35,000 Java Packages Impacted By Log4j Flaw, Google Warns
The Google Open Source Team scanned the Maven Central Java package repository and found that 35,863 packages (8% of the total) were using versions of the Apache Log4j library vulnerable to Log4Shell exploit and to the CVE-2021-45046 RCE.
“More than 35,000 Java packages, amounting to over 8% of the Maven Central repository (the most significant Java package repository), have been impacted by the recently disclosed log4j vulnerabilities (1, 2), with widespread fallout across the software industry.” reads the report published by Google. “As far as ecosystem impact goes, 8% is enormous.”
The Google experts used the Open Source Insights, a project used to determine open source dependencies, to assess all versions of all artifacts in the Maven Central Repository.
The experts pointed out that the direct dependencies account for around 7,000 of the affected packages. Most of the affected artifacts are related to indirect dependencies.
Since the vulnerability was disclosed, 13% of all vulnerable packages have been fixed (4,620).

Log4j Flaw: Attackers Are 'Actively Scanning Networks' Warns New Guidance, Joint Advisory from Cyber Agencies in US, Australia, Canada, New Zealand and the United Kingdom
A new informational Log4J advisory has been issued by cybersecurity leaders from the US, Australia, Canada, New Zealand and the United Kingdom. The guide includes technical details, mitigations and resources to address known vulnerabilities in the Apache Log4j software library.
The project is a joint effort by the US' Cybersecurity and Infrastructure Security Agency (CISA), FBI and NSA, as well as the Australian Cyber Security Centre (ACSC), Canadian Centre for Cyber Security (CCCS), Computer Emergency Response Team New Zealand (CERT NZ), New Zealand National Cyber Secure Centre (NZ NCSC), and the United Kingdom's National Cyber Security Centre (NCSC-UK).
The organisations said they issued the advisory in response to "active, worldwide exploitation by numerous threat actors, including malicious cyber threat actors." Numerous groups from North Korea, Iran, Turkey and China have been seen exploiting the vulnerability alongside a slate of ransomware groups and cybercriminal organisations.
Conti Ransomware Gang Has Full Log4Shell Attack Chain
The Conti gang was the first professional-grade, sophisticated ransomware group to weaponise Log4j2, now with a full attack chain.
The Conti ransomware gang, which last week became the first professional crimeware outfit to adopt and weaponize the Log4Shell vulnerability, has now built up a holistic attack chain.
The sophisticated Russia-based Conti group – which Palo Alto Networks has called “one of the most ruthless” of dozens of ransomware groups currently known to be active – was in the right place at the right time with the right tools when Log4Shell hit the scene 10 days ago, security firm Advanced Intelligence (AdvIntel) said in a report shared with Threatpost on Thursday.
As of Monday the attack chain has taken the following form, AdvIntel’s Yelisey Boguslavskiy told Threatpost: Emotet -> Cobalt Strike -> Human Exploitation -> (no ADMIN$ share) -> Kerberoast -> vCenter ESXi with log4shell scan for vCenter.

Second Ransomware Family Exploiting Log4j Spotted In US, Europe
This was quickly followed by a second ransomware group when researchers found a second family of ransomware has been growing in usage for attack attempts that exploit the critical vulnerability in Apache Log4j, including in the US and Europe.
A number of researchers, including at cybersecurity giant Sophos, have now said they’ve observed the attempted deployment of a ransomware family known as TellYouThePass. Researchers have described TellYouThePass as an older and largely inactive ransomware family — which has been revived following the discovery of the vulnerability in the widely used Log4j logging software.

Threat actors steal $80 million per month with fake giveaways, surveys
Scammers are estimated to have made $80 million per month by impersonating popular brands asking people to participate in fake surveys or giveaways.
Researchers warn of this new trend in global fraud schemes involving targeted links to make investigation and take-down increasingly challenging.
According to current estimates, these massive campaigns resulted in an estimated $80,000,000 per month, stolen from 10 million people in 91 countries.
The scam themes are the typical and "trustworthy" fake surveys and giveaways from popular brands with the holiday season making targets more susceptible to fraudulent gift offerings.
According to a report by Group-IB, there are currently 60 known scam networks that use targeted links in their campaigns, impersonating 121 brands in false giveaways.
Each network uses an average of 70 different Internet domain names as part of their campaigns, but some find great success with fewer domains, which indicates that quality beats quantity when it comes to scams.
Microsoft Teams might have a few serious security issues
Security researchers have discovered four separate vulnerabilities in Microsoft Teams that could be exploited by an attacker to spoof link previews, leak IP addresses and even access the software giant's internal services.
These discoveries were made by researchers at Positive Security who “stumbled upon” them while looking for a way to bypass the Same-Origin Policy (SOP) in Teams and Electron according to a new blog post. For those unfamiliar, SOP is a security mechanism found in browsers that helps stop websites from attacking one another.
During their investigation into the matter, the researchers found that they could bypass the SOP in Teams by abusing the link preview feature in Microsoft's video conferencing software by allowing the client to generate a link preview for the target page and then using either summary text or optical character recognition (OCR) on the preview image to extract information.

The Future of Work Has Changed, and Your Security Mindset Needs to Follow
VPNs have become a vulnerability that puts organisations at risk of cyber attacks.
When businesses first sent employees to work from home in March 2020 — thinking it'd only be for two weeks — they turned to quick fixes that would enable remote work for large numbers of people as quickly as possible. While these solutions solved the short-term challenge of allowing distributed workforces to connect to a company's network from anywhere, they're now becoming a security vulnerability that is putting organisations at risk of growing cyberattacks.
Now that almost two years have passed and work has fundamentally shifted, with fully or hybrid remote environments here to stay, business and security leaders need solutions that better fit their unique and increasingly complex needs. In fact, a new survey from Menlo Security has found that 75% of organisations are re-evaluating their security strategies for remote employees, exemplifying that accommodating remote work is a top priority for the majority of business leaders.
To successfully manage the risks that distributed workforces entail, leaders must shift their mindset away from the hub-and-spoke approach of providing connectivity to the entire network, instead segmenting access by each individual private application, wherever it is deployed, as threats of cyberattacks loom across all industries. As organisations grapple with the added security challenges that remote and hybrid work environments bring, adopting a zero-trust approach will be critical for end-to-end network and endpoint protection.
