Persistence

T1554 — Compromise Host Software Binary

Adversaries may modify host software binaries to establish persistent access to systems. Software binaries/executables provide a wide range of system commands or services, programs, and libraries. Common software binaries are SSH clients, FTP clients, email clients, web browsers, and many other user or server applications. Adversaries may establish persistence though modifications to host software binaries...

Investigate Compromise Host Software Binary activity in the context of Persistence: confirm scope, affected host/identity, and whether it matches expected administrative behaviour before deciding this is benign.
