Thread Execution Hijacking

Created the Saturday 23 March 2019. Updated 2 months, 2 weeks ago.

Thread execution hijacking is a technique used by malware to evade detection by targeting an existing thread of a process and avoiding any noisy process or thread creation operations. This technique allows the malware to run its code within the context of the targeted thread, without creating new processes or threads, which can be easily detected by security software.

During analysis, it is possible to observe calls to CreateToolhelp32Snapshot and Thread32First functions followed by OpenThread, which are used by the malware to enumerate and select the target thread.
