Detects unauthorized modification of file flags on core system binaries (e.g., /bin, /sbin, /usr/bin) followed by write/modification operations. This behavior is indicative of an attacker attempting to bypass immutable flags to modify or replace critical system files, often seen in rootkits or malware to achieve persistence or tamper with system integrity.
