Summary

Hide ▲

Gopher Strike and Sheet Attack are two Pakistan-linked campaigns that targeted Indian government entities with phishing, selective malware delivery, and nontraditional C2. The activity matters because the operators used previously undocumented tradecraft and limited payload delivery to India-based Windows systems. One campaign used Google Sheets, Firebase, and email for C2, while the other used a fake Adobe Acrobat Reader DC update to deliver an ISO payload. The tooling chain included GOGITTER, GITSHELLPAD, and GOSHELL, showing a layered approach to access and command execution.
