ChocoShell is a PowerShell credential stealer associated with the CaptiveCrunch campaign. Its code targets browser credentials, session cookies, Microsoft TokenBroker artifacts, and saved Wi-Fi passwords. It also implements mechanisms for bypassing browser encryption protections, evading security controls, and retrieving additional payloads.
Our analysis identified a flaw in ChocoShell’s administrator detection. When executed under a split-token local administrator account, the malware failed to recognize the Administrators SID marked as deny-only. Consequently, it triggered a visible UAC prompt instead of selecting its silent privilege-elevation mechanisms.
