Eset endpoint antivirus for windows12/31/2023 ![]() ![]() How can companies reduce risks associated with tools that claim to be able to disable anti-malware tools? Says Bestuzhev, “Users should have restricted user rights in the system. In terms of removal of the tool from the system, Bestuzhev advises: “If a user is an admin, it would be enough to simply uninstall the program through the "add/remove programs" feature in Windows, or through an official anti-malware uninstalling program.” He notes that “The end-user must be a local administrator, and must also accept the UAC acceptance prompt.” So what can be done to ‘terminate’ the Terminator tool once it has already been dropped to the system? Dmitry Bestuzhev, BlackBerry Senior Director of Cyber Threat Intelligence, points out that the tool will not run by itself without manual action from the user. Harris notes in his Reddit post that “This technique is similar to other Bring Your Own Driver (BYOD) campaigns being used by threat actors over recent years.” Remediation This elevates the aggressor to a privileged position within the system. Established threat actors such as BlackByte utilize vulnerable drivers that give the attacker the ability to execute malicious code in kernel context. The BYOVD attack technique has increasingly been adopted by those with malicious intent, ranging from ransomware gangs to state-sponsored cyber-espionage outfits, such as the North Korean hacking group Lazarus. Also included in the list was Windows Defender, on devices running Windows 7® and later.Īt the time of writing, the price Spyboy charges for this tool ranges from USD$3000 for an “all-in-one bypass,” to USD$300 for “a specific AV/EDR/XDR.”Īfter the vulnerable driver is written to the disk and the user has accepted the User Account Control (UAC) popup, the Terminator tool loads the driver and uses its kernel-level privileges to terminate security software processes, which are normally protected. But rather than taking the user’s “ clothes, boots, and motorcycle,” the author boasted that the Terminator tool was able to disable 23 AV/EDR/XDR products and controls, including products from Sophos, CrowdStrike, Kaspersky, McAfee, BitDefender, Malwarebytes, ESET, and more. On May 21, a new threat actor calling themselves Spyboy shared details of an antivirus-killing tool on the Russian Anonymous Marketplace (RAMP) called Terminator EDR Killer. Let’s take a look at the tool and discuss how organizations can protect themselves against it. The good news is that BlackBerry customers are protected by Cylance® AI from the Terminator EDR tool. A Russian-speaking threat actor going by the handle of Spyboy was recently reported to be selling an endpoint defense evasion tool that can allegedly “kill” every leading AV (antivirus), EDR (Endpoint Detection and Response) and XDR (Extended Detection and Response) product on the market. ![]()
