Why readSucuri documents a persistent WordPress backdoor using an eight-part self-healing mesh across files, database, and shared memory.

Security researchers analyzed a persistent WordPress backdoor, codenamed SC, that maintains self-healing persistence across eight distinct locations including files, database entries, and shared memory segments. If any component is deleted, another component restores the full set from database or shared-memory copies on the next page load. The malware avoids readable function names by using a substitution cipher decoder to scramble its payload.
