Suspicious Procfs Comm Overwrite Attempt with Kernel Thread Name
Author
Swachchhanda Shrawan Poudel (Nextron Systems)
Description
Detects attempts to overwrite a process's displayed name in /proc/[pid]/comm
with a kernel worker thread name. Attackers use this technique after launching
a renamed binary or LOLBin (e.g. curl, wget) to retroactively change how the
process appears in monitoring tools, providing a second layer of camouflage
beyond argv[0] spoofing.
