Information on attacker behaviors, incident reports and advice for security operations professionals is available on Sophos News SecOps Tactics, techniques, and procedures (TTPs) and more for different types of threats are available on SophosLabs Uncut, which provides SophosвЂ™ latest threat intelligence Sophos endpoint products, such as Intercept X, protect users by detecting the actions and behaviors of ransomware and other attacks, such as those described in this Sophos research.ДЇor further information read the article on SophosLabs Uncut.ДЇurther details on the evolving cyberthreat landscape can be found in the Sophos 2022 Threat Report We believe weвЂ™re seeing this for the first time.вЂќ

вЂњSophos has reported on Snatch and BlackMatter implementing the technique, however, neither of these ransomware groups attempted to install a subsequent application, such as AnyDesk, for command and control of the machines while in Safe Mode. They ensure that the ransomware has the best chance of running in Safe Mode and allow the attackers to retain remote access to the machines throughout the attack,вЂќ said Mackenzie. вЂњThe techniques used by AvosLocker are simple, but very clever. Setting up a new account with auto login details and then connecting to the targetвЂ™s domain controller to remotely access and run the ransomware executable, called update.exe Installing the legitimate remote administration tool AnyDesk and setting it to run in Safe Mode while connected to the network, ensuring continued command and control by the attacker

The command sequence takes approximately five seconds to execute and includes the following:Дisabling Windows update services and Windows DefenderДЄttempting to disable the components of commercial security software solutions that can run in Safe Mode

The script issues and implements a series of consecutive commands that prepare the machines for the release of the ransomware and then reboots into Safe Mode. Sophos researchers investigating the ransomware deployment found that the main sequence starts with attackers using PDQ Deploy to run and execute a batch script called вЂњlove.bat,вЂќ вЂњupdate.bat,вЂќ or вЂњlock.batвЂќ on targeted machines. вЂњThe message for IT security teams facing such an attack is that even if the ransomware fails to run, until they clean every trace of the attackersвЂ™ AnyDesk deployment from every impacted machine, they will remain exposed as the attackers have access to their organizationвЂ™s network and can lock them out again at any time.вЂќ

Sophos has never seen some of these components used with ransomware, and certainly not together,вЂќ said Peter Mackenzie, director of incident response at Sophos.

This creates a scenario where the attackers have full remote control over every machine theyвЂ™ve set up with AnyDesk, while the target organization is likely locked out of remote access to those computers. вЂњSophos discovered that the AvosLocker attackers installed AnyDesk so it works in Safe Mode, tried to disable the components of security solutions that run in Safe Mode, and then ran the ransomware in Safe Mode. The Sophos Rapid Response team has so far seen AvosLocker attacks in the Americas, Middle East and Asia-Pacific, targeting Windows and Linux systems.

Windows Safe Mode is an IT support method for resolving IT issues that disables most security and IT administration tools, while AnyDesk provides continuous remote access.ДЄvosLocker is a relatively new ransomware-as-a service that first appeared in late June 2021 and is growing in popularity, according to Sophos.

22, 2021 (GLOBE NEWSWIRE) - Sophos, a global leader in next-generation cybersecurity, today released new research about AvosLocker ransomware in the article, вЂњ AvosLocker Remotely Accesses Boxes, Even Running in Safe Mode.вЂќ SophosвЂ™ research explains how attackers attempt to bypass security controls by using a combination of Windows Safe Mode and the AnyDesk remote administration tool.
