Loading malware…
Sleestak is a PowerShell-based malware loader associated with Windows intrusion chains used in social-engineering campaigns targeting security conference attendees. It has been linked to infrastructure used to deliver follow-on payloads in multi-stage infections that relied on phishing lures, malicious documents, ClickOnce-style execution, and PowerShell-based retrieval of additional malware. In observed activity, Sleestak was tied to payload-delivery infrastructure later used alongside other tooling including NetSupport RAT and credential- and cryptocurrency-focused malware, indicating a role in staged compromise rather than as the final payload itself. Sleestak is associated with loader behavior on Windows systems and is notable for its use in broader campaigns that combined trusted-brand impersonation, host profiling, and modular payload delivery.
