•updated Sep 16, 2026•0•0•0

Detects instances where Acronis processes spawn common administrative or potentially sensitive utilities (such as chmod, chown, bash, or sudo) while running as a user other than root. This behavior may indicate an attempt to utilize Acronis for privilege escalation or unauthorized command execution on Linux systems.
