Threat Group Cards: A Threat Actor Encyclopedia Archived: 2026-04-05 21:12:35 UTC Home > List all groups > List all tools > List all groups using tool MSUpdater Tool: MSUpdater Names MSUpdater Category Malware Type Dropper, Backdoor, Info stealer, Exfiltration Description (ZScaler) The malware dropped and launched from the PDF exploit has been seen to be virtual machine (VM) aware in order to prevent analysis within a sandbox. The Trojan functionality is decrypted at run-time, and includes expected functionality, such as, downloading, uploading, and executing files driven by commands from the C&C. Communication with the C&C is over HTTP but is encoded to evade detection. The Trojan file name (e.g., 'msupdate.exe') and the HTTP paths used in the C&C (e.g., '/microsoftupdate/getupdate/default.aspx') are used to stay under the radar by appearing to be related to Microsoft Windows Update - hence the name given to this Trojan.
