DarkGate via Microsoft Teams: External Message Lure

An IT helpdesk coordinator at a logistics firm receives an urgent Teams chat from an external IT support account. The message links to a VBS script disguised as a VPN update. Running it kicks off a silent MSI install that drops a renamed AutoIt3 loader, which decrypts DarkGate in memory, registers a scheduled task for persistence, and begins beaconing to an HTTPS C2 server. Trace the chain from the Teams lure through the loader to the active backdoor.
