BlackFile Extortion Group Targets Retail and Hospitality
📞 Unit 42 and RH-ISAC report BlackFile has targeted retail and hospitality since Feb 2026, linking activity to CL-CRI-1116 and overlaps with UNC6671/Cordial Spider. The group uses vishing—impersonating IT helpdesks with spoofed VoIP—and phishing pages that mimic corporate SSO, plus antidetect browsers and residential proxies to harvest credentials and OTPs. After access they register devices to bypass MFA, escalate privileges, and exfiltrate data via Salesforce and SharePoint APIs. Recommendations include caller identity checks, strict escalation for IT support, and simulation-based phone-security training.
