DET0033 Detection Strategy for Accessibility Feature Hijacking via Binary Replacement or Registry Modification

AN0094 Analytic 0094

Defenders can observe suspicious replacement or tampering of system accessibility binaries (e.g., utilman.exe, sethc.exe, osk.exe) and anomalous modifications to registry keys used to redirect accessibility programs (such as IFEO keys). Additionally, execution of cmd.exe or other suspicious binaries triggered from the login screen by SYSTEM can be correlated as part of a behavior chain.
