Ransomware groups, such as Beast ransomware, have become significant threats in cybersecurity, utilizing advanced malware to encrypt data and demand ransoms. Beast ransomware, identified by Cybereason, has been active since 2022 and can target Windows, Linux, and ESXi operating systems. Originally developed in Delphi, it now uses C and Go. The ransomware employs elliptic-curve and ChaCha20 encryption techniques, features multithreaded file encryption, process termination, and shadow copy deletion on Windows. For Linux and ESXi, it offers customizable encryption paths and VM shutdown options. It spreads through phishing emails, compromised RDP endpoints, and SMB network scans, exploiting the RstrtMgr.dll for file access manipulation. Recent enhancements include an offline builder for configuring builds across various systems. The attack sequence starts with shadow copy deletion via a WMI query, followed by efficient file encryption targeting various file formats. A ransom note is placed in each affected directory, and users can access the ransomware's GUI during encryption. Recommendations to mitigate risks include tracking affiliates, promoting multi-factor authentication, enabling anti-malware solutions, implementing anti-ransomware measures, ensuring regular system patching, and backing up files.

Threat actors are increasingly using the open-source tool EDRSilencer to bypass endpoint detection and response (EDR) systems. EDRSilencer, originally designed for red teaming, silences EDR solutions by utilizing the Windows Filtering Platform (WFP) to block outbound network communications of EDR processes. It detects processes from various EDR products, including Carbon Black EDR, Cybereason, ESET Inspect, SentinelOne, Microsoft Defender, and others. Additional rules can be implemented to block processes not explicitly listed in the tool. The landscape of EDR evasion tools has expanded, with groups like FIN7 marketing AvNeutralizer to ransomware factions. Other tools include EDRKillShifter and PoorTry, which target and terminate security products. These tools are often sold as subscription services, making them accessible to threat actors with varying technical skills. Prices for these tools range from [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Threat actors are increasingly turning to the open-source tool EDRSilencer as a means to bypass endpoint detection and response (EDR) systems, according to recent findings from Trend Micro researchers. About EDRSilencer This software, originally designed for red teaming exercises, is now being misused to effectively “silence” EDR solutions. EDRSilencer operates by utilizing the Windows Filtering Platform (WFP), which enables the creation of tailored rules to monitor, block, and modify network traffic. As explained by the researchers, “The code leverages WFP by dynamically identifying running EDR processes and creating WFP filters to block their outbound network communications on both the internet protocols IPv4 and IPv6, effectively preventing EDRs from sending telemetry or alerts to their management consoles.” EDRSilencer currently detects processes from a wide range of EDR products, including: Carbon Black EDR Cybereason ESET Inspect SentinelOne Trellix EDR Microsoft Defender for Endpoint Microsoft Defender Antivirus Tanium TrendMicro Apex One And others Moreover, Trend Micro researchers noted that when certain processes are not explicitly listed within the tool, they can still be blocked by implementing additional rules. The Rise of EDR Evasion Tools The landscape of EDR evasion tools has expanded significantly, with groups like FIN7 marketing AvNeutralizer (also known as AuKill) to various ransomware factions since early 2023. This tool employs Windows’ TTD Monitor Driver and the Sysinternals Process Explorer driver to disrupt or crash protected EDR processes. RansomHub RaaS has been utilizing EDRKillShifter, while other RaaS actors have adopted PoorTry (also referred to as BurntCigar), a driver specifically designed to target and terminate security products. Additionally, Qilin ransomware attackers have been using “Killer Ultra,” which exploits a vulnerable Zemana driver to disable EDR and antivirus processes. Despite the differing mechanisms of these tools, the outcome remains consistent: endpoint security solutions are rendered ineffective. According to ExtraHop researchers, “EDR evasion tools are typically sold as subscription services, starting as low as 0 per month or 0 for a single bypass. The low price point makes these tools highly accessible to ransomware affiliates and other threat actors, including those with lower levels of technical proficiency.” On the higher end, some listings have been observed priced at ,500, and even as high as ,000 for packages that include EDR evasion capabilities alongside encryption lockers. In light of these developments, Trend Micro researchers recommend that organizations implement advanced detection mechanisms and proactive threat hunting strategies to mitigate the risks posed by EDR-killing tools. Additionally, Intel471 researchers have recently outlined methods for tracking EDRKillshifter, while ConnectWise Cyber Research has provided guidance on safeguarding organizations against BYOVD-based tools." max_tokens="3500" temperature="0.3" top_p="1.0" best_of="1" presence_penalty="0.1" frequency_penalty="frequency_penalty"] per month to ,500 or more for comprehensive packages.

Free antivirus tools are good for personal use, but paid antivirus tools offer more features, such as protection against malicious websites. Independent antivirus testing labs provide reports on antivirus tools, and some labs test Mac-specific antivirus apps as well. Useful features in antivirus tools include scanning files, blocking malware-hosting URLs, and behavior-based detection. Some antivirus tools also offer spyware protection, encryption, and webcam control. Free utilities for ransomware protection and cleaning up existing malware infestations are available, but they do not provide ongoing protection. Kaspersky products are no longer recommended due to criticism from various agencies. The top free antivirus software includes Avast One Basic and AVG Antivirus Free, which have received high scores from independent labs.
