AvosLocker, like many other threat actors, relies on a command and control mechanism to communicate with compromised systems. This typically involves a "dropper" – a piece of malicious software that, once the system is initially compromised, is downloaded onto disk and executed. A primary defense strategy for any organization should be to prevent the execution through the use of antivirus of these known malicious executables on endpoints. Contrary to some recommendations, it's crucial not to disable or remove antivirus protections. Instead, use it as your first line of defense against such threats.
