GOSHELL is a custom Golang-based shellcode loader used in the Pakistan-linked Gopher Strike cyberespionage campaign against Indian government entities. The activity has similarities to APT36 (Transparent Tribe), although attribution to that group is assessed only with medium confidence. GOSHELL delivers a stageless Cobalt Strike Beacon through multiple decoding stages and injects the resulting shellcode using QueueUserAPC. It applies hostname allowlisting before execution and inflates its portable executable overlay with junk data to hinder antivirus analysis and detection. GOSHELL is deployed as a later-stage payload following phishing-led compromise involving malicious PDF lures, ISO files, a Golang downloader, and a GitHub-based backdoor. It targets Windows systems and supports post-compromise Cobalt Strike operations over HTTPS.
