Cybereason Discovers Global Botnet Campaign Using Microsoft Exchange Vulnerabilities

Cybereason | April 23, 2021

Cybereason, the market leader in future-ready attack protection, reported today the discovery of a widespread, global campaign aimed at spreading the stealthy Prometei Botnet by attacking enterprises with a multi-stage attack to harvest computing power to mine bitcoin. To infiltrate networks, the threat actors, who tend to be Russian speakers, are exploiting previously disclosed Microsoft Exchange vulnerabilities used in the Hafnium attacks.

Prometei has a sophisticated infrastructure in place to guarantee its longevity on infected machines. Though Prometei was first reported in July 2020, Cybereason believes the botnet dates back to at least 2016, a year before the now-famous WannaCry and NotPetya malware attacks, which infected over 200 countries and caused billions of dollars in damage. Prometei is still evolving, with new features and tools being added daily.

“Because it has gone undetected, the Prometei Botnet poses a significant danger to companies. When attackers gain possession of infected machines, they can not only mine bitcoin by stealing processing power, but they can also exfiltrate classified information. The attackers may even inject the infected endpoints with other malware and work with ransomware groups to offer access to the endpoints if they so desire. To make matters worse, crypto mining consumes vital network computing power, adversely affecting business processes as well as the performance and reliability of sensitive servers,” said Assaf Dahan, Cybereason's senior director and head of threat research.

Key findings from the research, include:

• Wide range of Victims: Victims have been observed across a variety of industries, including Finance, Insurance, Retail, Manufacturing, Utilities, Travel, and Construction. Infected companies are based in countries around the world, including the United States, United Kingdom, Germany, France, Spain, Italy and other European countries, South America and East Asia.

• Russian Speaking Threat Actor: The threat actor appears to be Russian speaking and is purposely avoiding infections in former Soviet bloc countries.

• Exploiting SMB and RDP Vulnerabilities: The main objective of Prometei is to install the Monero crypto miner on corporate endpoints. To spread across networks, the threat actor is using known Microsoft Exchange vulnerabilities, in addition to known exploits EternalBlue and BlueKeep.

• Cross-Platform Threat: Prometei has both Windows-based and Linux-Unix-based versions, and it adjusts its payload based on the detected operating system on the targeted machines when spreading across the network.

• Cybercrime with APT Flavor: Cybereason assesses that the Prometei Botnet operators are financially motivated and intent on generating hefty sums of bitcoin, but is likely not backed by a nation-state.

• Resilient C2 Infrastructure: Prometei is designed to interact with four different C2 servers which strengthen the botnet’s infrastructure and maintain continuous communications, making it more resistant to takedowns.

Recommendations to companies for minimizing the Microsoft Exchange vulnerability include constantly scanning the environment for threats and imposing stricter patch management policies to ensure that all updates are deployed regularly. Sensitive network assets should also be hardened, multi-factor authentication implemented, and endpoint detection and response tools installed.

BlueVoyant Research Reveals Defending Digital Supply Chains Remains a Business Challenge

BlueVoyant | November 14, 2022

BlueVoyant, an industry-leading cyber defense company that combines internal and external cybersecurity, today released the findings of its third annual global survey into supply chain cyber risk management. The study reveals that 98% of firms surveyed have been negatively impacted by a cybersecurity breach that occurred in their supply chain. This is up slightly from 97% of respondents last year. Digital supply chains are made of the external vendors and suppliers who have network access that could be compromised. "The survey shows that supply chain cybersecurity risk has not decreased and, in fact, more enterprises than ever have reported being negatively impacted by a cybersecurity disturbance in their supply chain," said Adam Bixler, BlueVoyant's global head of supply chain defense. "The good news is that across industries and regions, organizations are making supply chain defense a priority, but these organizations need to better monitor suppliers and work with them to remediate issues to reduce their supply chain risk." Other key survey findings include: 40% of respondents rely on the third-party vendor or supplier to ensure adequate security. In 2021, 53% of companies said they audited or reported on supplier security more than twice per year; that number has improved to 67% in 2022. These numbers include enterprises monitoring in real time. Budgets from supply chain defense are increasing, with 84% of respondents saying their budget has increased in the past 12 months. The top pain points reported are internal understanding across the enterprise that suppliers are part of their cybersecurity posture, meeting regulatory requirements, and working with suppliers to improve their security. "While supply chain defense is a challenge, there are solutions for enterprises to better defend against this risk," said James Rosenthal, BlueVoyant's CEO and co-founder. "Enterprises should continuously monitor their supply chain to be able to quickly remediate threats. As companies are being negatively impacted by supply chain disturbances, they must prioritize this risk with the appropriate budget." The study was conducted by independent research organization, Opinion Matters, and recorded the views and experiences of 2,100 chief technology officers (CTOs), chief security officers (CSOs), chief operating officers (COOs), chief information officers (CIOs), chief info security officers (CISOs), and chief procurement officers (CPOs) responsible for supply chain and cyber risk management in organizations with more than 1,000 employees across a range of industries. These include: business services, financial services, healthcare and pharmaceutical, manufacturing, utilities and energy, and defense. It covered 11 countries: U.S., Canada, Germany, Austria, Switzerland, France, the Netherlands, the United Kingdom, Australia, the Philippines, and Singapore. The 2021 research was also conducted by Opinion Matters and recorded the views and experiences of 1,200 CTOs/CSOs/COOs/CIOs/CISOs/CPOs in similar enterprises and the same industries. It covered six countries: U.S., Canada, Germany, the Netherlands, the U.K., and Singapore. Analysis of the responses from different commercial sectors revealed considerable variations in their experiences of supply chain risk: While healthcare and pharmaceutical was the third-highest vertical in terms of experiencing greater board scrutiny for supply chain risk at 42%, the sector also indicates the lowest likelihood to increase budget for external resources to bolster supply chain cybersecurity, by a margin of 7% below the next closest vertical. This sector is also the least likely of any vertical (34%) to have no way of knowing if an issue arises with a third party's environment. The energy sector was most likely to report negative impact from at least one supply chain breach in the last year (99%) but 49% are monitoring supply chain cyber risk regularly or in real time, and 44% are updating senior leadership monthly or more frequently. In addition, energy companies say they are increasing their budget for supply chain cyber risk by an average of 60%. In manufacturing, 64% of respondents say that supply chain cyber risk is on their radar and 44% say they have established an integrated enterprise risk management program.

Legit Security Discovers New Class of Development Pipeline Vulnerabilities; Open-Source Rust Programming Language Found Vulnerable

Legit Security | December 12, 2022

Legit Security, a cyber security company with an enterprise platform that protects an organization's software supply chain from attack and ensures secure application delivery, today announced that it discovered a new class of software supply chain vulnerabilities that leverage artifact poisoning to attack underlying software development pipelines. The vulnerability was found in GitHub Actions, a platform for orchestrating and automating software development pipelines, and the vulnerability was identified in the highly popular programming language Rust. Many other GitHub Action projects remain potentially vulnerable and a technical disclosure blog including information to protect organizations from attack is available on Legit Security’s website. The discovered pipeline vulnerability could allow any GitHub user to replace legitimate development artifacts with malicious ones, enabling attackers to modify source code, steal secrets and create CodeCov-like wide-reaching software supply chain attacks. Rust, an extremely popular programming language used by millions of developers, acknowledged and fixed the vulnerability after initial disclosure by the Legit Security Research Team. GitHub Actions is part of the extremely popular GitHub source code management system at the heart of many organization’s software supply chains and used by software developers globally. The vulnerability affects the GitHub Actions artifacts storage mechanism, which is used to store and transfer build artifacts between software development build jobs. Due to a limitation in the cross-workflow artifact communication mechanism, vulnerable workflows cannot distinguish between legitimate project artifacts and artifacts that were created by the project’s forks or copies, allowing any user to create a fork, and then craft a malicious artifact that will be treated as a legitimate one. “This is a different class of vulnerability that can lead to attacks and modification of the development pipeline itself, not just modification of the code. “A simple analogy could be made to a car assembly line. This is an attack on the assembly line itself that could include stealing sensitive parts, turning off certain steps, or substituting any valid part for a malicious one. It’s a powerful attack vector that gives cyber criminals a lot of options to inflict damage. In this case, the vulnerable targets are software supply chains that use GitHub Action.” Liav Caspi, co-founder and CTO, Legit Security The Legit Security Research Team also disclosed the security issue to the GitHub security team. GitHub responded by simply updating their API to include information that could help prevent this vulnerability. It should be noted that GitHub didn’t address the root cause of the issue, thus leaving many other GitHub Action projects vulnerable to the aforementioned software supply chain attacks. Legit Security’s technical disclosure blog includes important information on how to protect organizations from this type of attack. More information about general GitHub security best practices can also be found here. Legit Security Legit Security protects an organization's software supply chain from attack and ensures secure application delivery, governance and risk management from code to cloud. The platform’s unified application security control plane and automated SDLC discovery and analysis capabilities provide visibility and security control over rapidly changing environments, and allow security issues to be prioritized based on context and business criticality to improve security team efficiency and effectiveness.
