Black Arrow Cyber Threat Briefing 05 August 2022

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

• Average Cost of Data Breaches Hits Record High of $4.35 Million: IBM

The global average cost of data breaches reached an all-time high of $4.35 million in 2022 compared with $4.24 million in 2021, according to a new IBM Security report. About 60% of the breached organisations raised product and services prices due to the breaches.

The annual report, conducted by Ponemon Institute and analysed and sponsored by IBM Security, is based on the analysis of real-world data breaches experienced by 550 organisations globally between March 2021 and March 2022.

According to the report, about 83% of the organisations have experienced more than one breach in their lifetime, with nearly half of the costs reported to be incurred more than a year after the breach.

The report revealed that ransomware and destructive attacks represented 28% of breaches among the critical infrastructure organisations studied, indicating that threat actors are specifically targeting the sector to disrupt global supply chains. The critical infrastructure sector includes financial services, industrial, transportation, and healthcare companies.

• Researchers Warns of Large-Scale Adversary-in-the-Middle (AiTM) Attacks Targeting Enterprise Users

A new, large-scale phishing campaign has been observed using adversary-in-the-middle (AitM) techniques to get around security protections and compromise enterprise email accounts.

It uses a technique capable of bypassing multi-factor authentication. The campaign is specifically designed to reach end users in enterprises that use Microsoft's email services.

Prominent targets include fintech, lending, insurance, energy, manufacturing, and federal credit union verticals located in the US, UK, New Zealand, and Australia.

This is not the first time such a phishing attack has come to light. Last month, Microsoft disclosed that over 10,000 organisations had been targeted since September 2021 by means of AitM techniques to breach accounts secured with multi-factor authentication (MFA).

The ongoing campaign, effective June 2022, commences with an invoice-themed email sent to targets containing an HTML attachment, which includes a phishing URL embedded within it.

• UK NHS Suffers Outage After Cyber Attack on Managed Service Provider

The UK National Health Service (NHS) 111 emergency services were affected by a significant and ongoing outage triggered by a cyber attack that hit the systems of British managed service provider (MSP) Advanced.

Advanced's Adastra client patient management solution, which is used by 85% of NHS 111 services, was hit by a major outage together with several other services provided by the MSP, according to a status page.

"There was a major outage of a computer system that is used to refer patients from NHS 111 Wales to out-of-hours GP providers," the Welsh Ambulance Services said. "This system is used by Local Health Boards to coordinate these services for patients. The ongoing outage is significant and has been far-reaching, impacting each of the four nations in the UK."

The UK public was advised to access the NHS 111 emergency services using the online platform until the incident is resolved.

While no details were provided regarding the nature of the cyber attack, based on the wording, it is likely that this was a ransomware or data extortion attack.

• A Third of Organisations Experience a Ransomware Attack Once a Week

Ransomware attacks show no sign of slowing. According to new research published by Menlo Security, a third of organisations experience a ransomware attack at least once a week, with one in 10 experiencing them more than once a day.

The research, conducted among 500+ IT security decision makers at US and UK organisations with more than 1,000 employees, highlights the impact this is having on security professionals’ own wellbeing. When asked what keeps them awake at night, 41% of respondents say they worry about ransomware attacks evolving beyond their team’s knowledge and skillset, while 39% worry about them evolving beyond their company’s security capabilities.

Their biggest concern, however, is the risk of employees ignoring corporate security advice and clicking on links or attachments containing malware (46%). Respondents worry more about this than they do their own job security, with just a quarter (26%) of respondents worried about losing their job.

According to the report, around half of organisations (61% US and 44% UK) have been the victim of a successful ransomware attack in the last 18 months, with customers and prospects the most likely entry point for an attack.

Partners/suppliers and employees/contractors are also seen as serious security risks, although one in 10 admit they are unable to identify how the attacks got in. The top three ransomware attack vectors are email (54%), web browsers via a desktop or laptop (49%) and mobile devices (39%).

• Ransomware Products and Services Ads on Dark Web Show Clues to Danger

Why is ransomware’s destructive potential so daunting? Some clues are in the “for sale” ads. In an examination of some 35 million dark web URLs, a provider of machine identity management and a forensic specialist found some 475 web pages peddling sophisticated ransomware products and services with a number of high profile crews hawking ransomware-as-a-service.

The work is a joint effort between the Salt Lake City-based Venafi and Forensic Pathways, which took place between November 2021 and March 2022. Researchers used Forensic’s Dark Search Engine to carry out the investigation.

Here are some of the research findings:

• 87% of the ransomware found on the dark web has been delivered via malicious macros to infect targeted systems.

• 30 different “brands” of ransomware were identified within marketplace listings and forum discussions.

• Many strains of ransomware being sold — such as Babuk, GoldenEye, Darkside/BlackCat, Egregor, HiddenTear and WannaCry — have been successfully used in high-profile attacks.

• Ransomware strains used in high-profile attacks command a higher price for associated services. For example, the most expensive listing was $1,262 for a customised version of Darkside ransomware, which was used in the Colonial Pipeline ransomware attack.

• Source code listings for well-known ransomware generally command higher price points. For example, Babuk source code is listed for $950 and Paradise source code is selling for $593.

Ransomware Sold for as Little as $1: In addition to a variety of ransomware at various price points, a wide range of services and tools that help make it easier for attackers with minimal technical skills to launch ransomware attacks are for sale on the dark web, Venafi said. Services with the greatest number of listings include those offering source code, build services, custom development services and ransomware packages that include step-by-step tutorials.

• Wolf In Sheep’s Clothing: How Malware Tricks Users and Antivirus

One of the primary methods used by malware distributors to infect devices is by deceiving people into downloading and running malicious files, and to achieve this deception, malware authors are using a variety of tricks.

Some of these tricks include masquerading malware executables as legitimate applications, signing them with valid certificates, or compromising trustworthy sites to use them as distribution points.

According to VirusTotal, a security platform for scanning uploaded files for malware, some of these tricks are happening on a much larger scale than initially thought.

The platform has compiled a report presenting stats from January 2021 until July 2022, based on the submission of two million files daily, illustrating trends in how malware is distributed.

• Abusing legitimate domains: Distributing malware through legitimate, popular, and high-ranking websites allows threat actors to evade IP-based blocklists, enjoy high availability, and provide a greater level of trust.

• Using stolen code-signing certificates: Signing malware samples with valid certificates stolen from companies is a reliable way to evade AV detection and security warnings on the host. Of all the malicious samples uploaded to VirusTotal between January 2021 and April 2022, over a million were signed, and 87% used a valid certificate.

• Disguised as popular software: Masquerading a malware executable as a legitimate, popular application has seen an upward trend in 2022. Victims download these files thinking they’re getting the applications they need, but upon running the installers, they infect their systems with malware. The most mimicked applications are Skype, Adobe Acrobat, VLC, and 7zip.

• Lacing legitimate installers - Finally, there’s the trick of hiding malware inside legitimate application installers and running the infection process in the background while the real apps execute in the foreground. Based on VirusTotal stats, this practice also appears to be on the rise this year, using Google Chrome, Malwarebytes, Windows Updates, Zoom, Brave, Firefox, ProtonVPN, and Telegram as lures.

• Microsoft Accounts Targeted with New MFA-Bypassing Phishing Kit

A new large-scale phishing campaign targeting credentials for Microsoft email services use a custom proxy-based phishing kit to bypass multi-factor authentication.

Researchers believe the campaign's goal is to breach corporate accounts to conduct BEC (business email compromise) attacks, diverting payments to bank accounts under their control using falsified documents.

The phishing campaign's targets include fin-tech, lending, accounting, insurance, and Federal Credit Union organisations in the US, UK, New Zealand, and Australia.

The campaign was discovered by Zscaler's ThreatLabz researchers, who report that the operation is still ongoing, and the phishing actors register new phishing domains almost daily.

Starting in June 2022, Zscaler's analysts noticed a spike in sophisticated phishing attempts against specific sectors and users of Microsoft email services.

Some of the newly registered domains used in the campaign are typo-squatted versions of legitimate domains.

Notably, many phishing emails originated from the accounts of executives working in these organisations, whom the threat actors most likely compromised earlier.

• Cyber Attack Prevention Is Cost-Effective, So Why Aren’t Businesses Investing to Protect?

Cyber attacks like ransomware, BEC scams and data breaches are some of the key issues businesses are facing today, but despite the number of high-profile incidents, many boardrooms are reluctant to free up budget to invest in the cyber security measures necessary to avoid becoming the next victim.

In a Help Net Security interview, Former Pentagon Chief Strategy Officer Jonathan Reiber, VP Cyber security Strategy and Policy, AttackIQ, discusses how now, more than ever, companies need to protect themselves from cyber threat actors. He offers insight for CISOs, from talking to the Board to proper budget allocation.

• Securing Your Move to the Hybrid Cloud

The combination of private and public cloud infrastructure, which most organisations are already using, poses unique security challenges. There are many reasons why organisations adopt the public cloud, from enabling rapid growth without the burden of capacity planning to leveraging flexibility and agility in delivering customer-centric services. However, this use can leave companies open to threats.

Since regulatory requirements or other preferences dictate that certain applications remain on private (on-prem) infrastructure, many organisations choose to maintain a mix of private and public infrastructure. Additionally, organisations typically use multiple cloud providers simultaneously or preserve the option to move between providers. However, this hybrid approach presents unique and diverse security challenges. Different cloud providers and private cloud platforms may offer similar capabilities but different ways of implementing security controls, along with disparate management tools.

The question then becomes: How can an organisation maintain consistent governance, policy enforcement and controls across different clouds? And how can it ensure that it maintains its security posture when moving between them? Fortunately, there are steps professionals can take to ensure that applications are continuously secure, starting from the early stages of development and extending throughout the lifecycle.

• Lessons from the Russian Cyber Warfare Attacks

Cyber warfare tactics may not involve tanks and bombs, but they often go hand-in-hand with real combat.

The Russian invasion of Ukraine is a prime example. Before Russian troops crossed the border, Russian hackers had already taken down Ukrainian government websites. And after the conflict started, the hacktivist group Anonymous turned the tables by hacking Russian media to shut down propaganda about the war.

In these unprecedented times of targeted attacks against governments and financial institutions, every organisation should be on heightened alert about protecting their critical infrastructure and digital attack surface.

With the Russia-Ukraine conflict as a backdrop, two Trend Micro security experts recently discussed cyber warfare techniques and how they’re an important reminder for every business to proactively manage cyber risk.

• Four Sneaky Attacker Evasion Techniques You Should Know About

Remember those portrayals of hackers in the 80s and 90s where you just knew when you got pwned? A blue screen of death, a scary message, a back-and-forth text exchange with a hacker—if you got pwned in a movie in the 80s and 90s, you knew it right off the bat.

What a shame that today’s hackers have learned to be quiet when infiltrating an environment. Sure, “loud” attacks like ransomware still exist, but threat actors have learned that if they keep themselves hidden, they can usually do far more damage. For hackers, a little stealth can go a long way. Some attack tactics are inherently quiet, making them arguably more dangerous as they can be harder to detect. Here are four of these attack tactics you should know about.

1. Trusted Application Abuse: Attackers know that many people have applications that they inherently trust, making those trusted applications the perfect launchpad for cyber attacks. Threat actors know that defenders and the tools they use are often on the hunt for new malware presenting itself in environments. What isn’t so easy to detect is when the malware masquerades under legitimate applications.

2. Trusted Infrastructure Abuse: Much like trusted application abuse, trusted infrastructure abuse is the act of using legitimate, publicly hosted services and toolsets (such as Dropbox or Google Drive) as part of the attack infrastructure. Threat actors know that people tend to trust Dropbox and Google Drive. As a result, this makes these tools a prime means for threat actors to carry out malicious activity. Threat actors often find trusted infrastructure abuse easy because these services aren’t usually blocked at an enterprise’s gateway. In turn, outbound communications can hide in plain sight.

3. Obfuscation: Although cyber security has more than its fair share of tedious acronyms, the good news is that many terms can be broken down by their generic dictionary definitions. According to dictionary.com, this is what obfuscate means: “To make something unclear, obscure or difficult to understand.” And that’s exactly what it means in cyber security: finding ways to conceal malicious behaviour. In turn, this makes it more difficult for analysts and the tools they use to flag suspicious or malicious activity.

4. Persistence: Imagine writing up documentation using your computer, something you may well do in your role. You’ve spent a ton of time doing the research required, finding the right sources and compiling all your information into a document. Now, imagine not hitting save on that document and losing it as soon as you reboot your computer. Sound like a nightmare—or perhaps a real anxiety-inducing experience you’ve been through before? Threat actors agree. And that’s why they establish persistence. They don’t want all of their hard work to get into your systems in the first place to be in vain just because you restart your computer. They establish persistence to make sure they can still hang around even after you reboot.

• Zero-Day Defence: Tips for Defusing the Threat

Because they leave so little time to patch and defuse, zero-day threats require a proactive, multi-layered approach based on zero trust.

The recent Atlassian Confluence remote code execution bug is just the latest example of zero-day threats targeting critical vulnerabilities within major infrastructure providers. The specific threat, an Object-Graph Navigation Language (OGNL) injection, has been around for years but took on new significance given the scope of the Atlassian exploit. And OGNL attacks are on the rise.

Once bad actors find such a vulnerability, proof-of-concept exploits start knocking at the door, seeking unauthenticated access to create new admin accounts, execute remote commands, and take over servers. In the Atlassian case, Akamai's threat research team identified that the number of unique IP addresses attempting these exploits grew to more than 200 within just 24 hours.

Defending against these exploits becomes a race against time worthy of a 007 movie. The clock is ticking and you don't have much time to implement a patch and "defuse" the threat before it's too late. But first you need to know that an exploit is underway. That requires a proactive, multi-layered approach to online security based on zero trust.

What do these layers look like? There are a number of different practices that security teams — and their third-party Web application and infrastructure partners — should be aware of.

Black Arrow Cyber Threat Briefing 08 April 2022

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

• Nearly Two-Thirds of Ransomware Victims Paid Ransoms Last Year, Finds "2022 Cyberthreat Defense Report"

CyberEdge Group, a leading research and marketing firm serving the cyber security industry’s top vendors, announced the launch of its ninth annual Cyberthreat Defense Report (CDR). The award-winning CDR is the standard for assessing organisations’ security posture, gauging perceptions of information technology (IT) security professionals, and ascertaining current and planned investments in IT security infrastructure – across all industries and geographic regions.

A record 71% of organisations were impacted by successful ransomware attacks last year, according to the 2022 CDR, up from 55% in 2017. Of those that were victimised, nearly two-thirds (63%) paid the requested ransom, up from 39% in 2017.

• New Android Banking Malware Remotely Takes Control of Your Device

A new Android banking malware named Octo has appeared in the wild, featuring remote access capabilities that allow malicious operators to perform on-device fraud.

Octo is an evolved Android malware based on ExoCompact, a malware variant based on the Exo trojan that quit the cyber crime space and had its source code leaked in 2018.

The new variant has been discovered by researchers at ThreatFabric, who observed several users looking to purchase it on darknet forums.

https://www.bleepingcomputer.com/news/security/new-android-banking-malware-remotely-takes-control-of-your-device/

• Network Intrusion Detections Skyrocketing

A WatchGuard report shows a record number of evasive network malware detections with advanced threats increasing by 33%, indicating a higher level of zero day threats than ever before.

Researchers detected malware threats in EMEA at a much higher rate than other regions of the world in Q4 2021, with malware detections per Firebox at 49%, compared to Americas at 23% and APAC at 29%. The trajectory of network intrusion detections also continued its upward climb with the largest total detections of any quarter in the last three years and a 39% increase quarter over quarter.

Researchers suggest that this may be due to the continued targeting of old vulnerabilities as well as the growth in organisations’ networks. As new devices come online and old vulnerabilities remain unpatched, network security is becoming more complex.

https://www.helpnetsecurity.com/2022/04/08/network-malware-detections/

• Organisations Underestimating the Seriousness of Insider Threats

Imperva releases data that shows organisations are failing to address the issue of insider threats during a time when the risk is at its greatest.

New research, conducted by Forrester, found that 59% of incidents in EMEA organisations that negatively impacted sensitive data in the last 12 months were caused by insider threats, and yet 59% do not prioritise insider threats the way they prioritise external threats. Despite the fact that insider events occur more often than external ones, they receive lower levels of investment.

This approach is at odds with today’s threat landscape where the risk of malicious insiders has never been higher. The rapid shift to remote working means many employees are now outside the typical security controls that organisations employ, making it harder to detect and prevent insider threats.

Further, the Great Resignation is creating an environment where there is a higher risk of employees stealing data. This data could be stolen intentionally by people looking to help themselves in future employment, because they are disgruntled and want revenge, or it could be taken unintentionally when a careless employee leaves the business with important information.

• Watch Out for Phishing Emails from Genuine Mailing Lists, Following Mailchimp Hack

A Mailchimp hack means that you’ll want to be even more vigilant than usual about phishing emails. Attackers have taken a clever approach to making their emails appear genuine …

When you subscribe to an email list, there’s a decent chance that the emails you received are actually sent by a company called Mailchimp, rather than directly by the company itself. Mailchimp offers companies a range of tools that make it easy to manage email databases, and send marketing emails and newsletters.

Hackers managed to gain access to more than 100 Mailchimp customer accounts, giving them the ability to send emails that would appear to have come from any one of those businesses.

Users will need to be more vigilant when receiving emails and avoid clicking on links in emails, even if they appear genuine.

• SpringShell Attacks Target About One in Six Vulnerable Orgs

Roughly one out of six organisations worldwide that are impacted by the Spring4Shell zero-day vulnerability have already been targeted by threat actors, according to statistics from one cyber security company.

The exploitation attempts took place in the first four days since the disclosure of the severe remote code execution (RCE) flaw, tracked as CVE-2022-22965, and the associated exploit code.

According to Check Point, who compiled the report based on their telemetry data, 37,000 Spring4Shell attacks were detected over the past weekend alone.

• New Threat Group Underscores Mounting Concerns Over Russian Cyber Threats

Crowdstrike says Ember Bear is likely responsible for the wiper attack against Ukrainian networks and that future Russian cyber attacks might target the West.

As fears mount over the prospects of a “cyberwar” initiated by the Russian government, the number of identified Russian threat actors also continues to climb. Last week CrowdStrike publicly revealed a Russia-nexus state-sponsored actor that it tracks as Ember Bear.

CrowdStrike says that Ember Bear (also known as UAC-0056, Lorec53, Lorec Bear, Bleeding Bear, Saint Bear) is likely an intelligence-gathering adversary group that has operated against government and military organisations in eastern Europe since early 2021. The group seems “motivated to weaponize the access and data obtained during their intrusions to support information operations (IO) aimed at creating public mistrust in targeted institutions and degrading government ability to counter Russian cyber operations,” according to CrowdStrike intelligence.

Despite its state-sponsored Russia nexus, Ember Bear differs from its better-known kin such as Fancy Bear or Voodoo Bear because CrowdStrike can’t tie it to a specific Russian organisation. Its target profile, assessed intent, and technical tactics, techniques, and procedures (TTPs) are consistent with other Russian GRU cyber operations.

• Consumer Fraud Tripled in The Last Two Years

Reported cases of consumer fraud more than tripled in the years 2020-2021 from prior years, finds a new report by Accenture, presenting a growing challenge for public safety agencies to find new strategies to counter the trend.

The report compiled data from eight developed nations (Australia, Canada, France, Germany, Italy, Singapore, the United Kingdom, and the United States) on consumer fraud, defined as any fraud directly targeting citizens and excluding fraud targeting government agencies and companies. Reports of such fraud increased at an estimated 6.8% rate annually during 2013-2019 and then increased to a 22.5% annual growth rate yearly during 2020-2021 in parallel with the large shift of workers and consumers to digital channels and greater use of technology during the pandemic.

• Borat RAT: Multiple Threat of Ransomware, DDoS and Spyware

A new remote access trojan (RAT) dubbed "Borat" doesn't come with many laughs but offers bad actors a menu of cyberthreats to choose from.

RATs are typically used by cyber criminals to get full control of a victim's system, enabling them to access files and network resources and manipulate the mouse and keyboard. Borat does all this and also delivers features to enable hackers to run ransomware, distributed denial of service attacks (DDoS) and other online assaults and to install spyware, according to researchers at cyber security biz Cyble.

"The Borat RAT provides a dashboard to Threat Actors (TAs) to perform RAT activities and also has an option to compile the malware binary for performing DDoS and ransomware attacks on the victim's machine," the researchers wrote in a blog post, noting the malware is being made available for sale to hackers.

Borat – named after the character made famous by actor Sacha Baron Cohen in two comedy films – comes with the standard requisite of RAT features in a package that includes such functions as builder binary, server certificate and supporting modules.

• Bank Had No Firewall License, Intrusion or Phishing Protection – Guess the Rest

An Indian bank that did not have a valid firewall license, had not employed phishing protection, lacked an intrusion detection system and eschewed use of any intrusion prevention system has, shockingly, been compromised by criminals who made off with millions of rupees.

The unfortunate institution is called the Andra Pradesh Mahesh Co-Operative Urban Bank. Its 45 branches and just under $400 million of deposits make it one of India's smaller banks.

It certainly thinks small about security – at least according to Hyderabad City Police, which last week detailed an attack on the Bank that started with over 200 phishing emails being sent across three days in November 2021. At least one of those mails succeeded in fooling staff, resulting in the installation of a Remote Access Trojan (RAT).

Another technology the bank had chosen not to adopt was virtual LANs, so once the RAT went to work the attackers gained entry to the Bank's systems and were able to roam widely – even in its core banking application

• Global APT Groups Use Ukraine War for Phishing Lures

Security researchers have detected multiple APT campaigns leveraging Ukraine war-themed documents and news sources to lure victims into clicking on spear-phishing links.

Check Point Research said victim locations ranged from South America to the Middle East, with malware downloads designed to perform keylogging and screenshotting and execute commands.

The threat groups in question include El Machete, which is targeting the financial and government sectors in Nicaragua and Venezuela with malicious macro-laden Word documents containing articles on the war.

One of the docs was an article written by the Russian ambassador to Nicaragua titled: “Dark plans of the neo-Nazi regime in Ukraine.”

Another is Lyceum, an Iranian state-linked group targeting the energy sector with emails about war crimes in Ukraine that link to a malicious document hosted elsewhere. Its victims so far have been in Israel and Saudi Arabia, according to Check Point.

One email contained a link to an article from The Guardian hosted on the news-spot[.]live domain, alongside several malicious docs about the war.

• Paying Ransom Doesn’t Guarantee Data Recovery

OwnBackup announced the findings of a global survey conducted by Enterprise Strategy Group (ESG) that reveals a staggering 79% of respondent organisations have been targeted by ransomware within the past 12 months. Of those organisations, nearly three quarters said the attack was successful, meaning that it disrupted business operations.

Other key findings

·       Of the respondents that said their organisation paid a cyber ransom to regain access to data, applications, and/or systems after an attack, only 14% were able to recover all of their data.

·       87% of respondents who made ransom payments said that they experienced additional extortion attempts beyond the initial ransomware demand.

·       31% of respondent organisations targeted by ransomware indicated that application user and permission misconfigurations were the initial point of compromise.

·       87% of respondents are very or somewhat concerned about their backups being infected by ransomware attacks.
