Not all solutions are equal; some can consume significantly more computer resources to do their job and cause a frustrating slowdown of your computer’s responsiveness. Choosing the best security software and ensuring it has the correct configurations can significantly impact computer performance.

The script contains the actual malware payload (in base64-encoded and encrypted form) in a string variable at the top of the script. Unit 42 reached out to notify Microsoft of the Office Test persistence mechanism and its use by a threat group in targeted attacks. On July 4, 2016, Microsoft released a new version of Autoruns, specifically v13.52 that includes checks for the Office Test registry keys. We downloaded Autoruns v13.52 and tested both the GUI (Autoruns.exe) and CLI (autorunsc.exe) versions of the tool on a system compromised with the Sofacy tool that used this persistence technique.
