Executive Summary

\nDeceptor (often detected as Rogue.Deceptor or Riskware.FakeAV) is a highly deceptive Potentially Unwanted Program (PUP) operating as \"Rogue Security Software.\" It employs aggressive scareware tactics, masquerading as a legitimate Windows security component or premium anti-malware suite. It performs fabricated system \"scans\" to generate alarming false-positive reports about severe malware infections, with the sole objective of frightening the user into purchasing a fraudulent \"premium license\" to \"clean\" their machine.\n\n

Infection Vector and Technical Capabilities

\nDeceptor relies almost entirely on aggressive malvertising, Search Engine Optimization (SEO) poisoning, and deceptive software bundling. Users typically encounter it via alarming, full-screen browser pop-ups (e.g., \"Your Windows is infected with 5 viruses!\") that trick them into downloading the rogue installer.\n\nOnce installed, the software employs highly aggressive extortion tactics:\n\n\n

Threat Assessment

\nWhile technically not destructive malware like a file-encrypting ransomware, Deceptor poses a severe threat to user productivity and financial security (extortion). The aggressive system locking mechanisms cause massive IT helpdesk overhead, and users may unwittingly hand over valid credit card details to cybercriminals.\n\n

Victims should never pay the extortion demand, as payment fuels criminal operations without guaranteeing file restoration. The recommended recovery procedure entails isolating infected hosts, conducting forensic disk imaging, identifying the root access vector, and restoring validated systems from immutable offline backups." } } ], "faq_count": 5, "mitre_attack": [ "T1491", "T1562.001", "T1112" ], "cisa_advisory": null, "last_updated": "2026-10-15", "type": "Riskware / Rogue Security Software", "target_industries": [ "Healthcare", "Critical Infrastructure", "Enterprise" ], "motivation": "Financial Extortion", "threat_actors": [ "Unknown / Cybercriminal" ], "target_geographies": [ "Global" ], "attack_stage": [ "defense_evasion", "impact" ], "ecosystem": [ "windows_pe" ], "is_emerging": false, "mitre_attack_detail": [ { "id": "T1491", "name": "Defacement (Displaying fake security warnings / Scareware)", "tactic": "Impact" }, { "id": "T1562.001", "name": "Impair Defenses: Disable or Modify Tools", "tactic": "Defense Evasion" }, { "id": "T1112", "name": "Modify Registry", "tactic": "Defense Evasion" } ], "containment_steps": [ "Immediately isolate affected host(s) from the internal network (disconnect physical Ethernet and disable Wi-Fi/Bluetooth) to prevent Deceptor from spreading laterally or encrypting network-attached storage (NAS) and shared SMB volumes.", "Preserve volatile system memory (RAM capture) on a representative endpoint before attempting a reboot or power-down, as Deceptor symmetric encryption keys or uncompiled payload components may still reside in memory.", "Audit process execution logs and terminate active scripting interpreters (e.g. PowerShell, CMD, WScript) or commands executing 'vssadmin.exe delete shadows' or 'wbadmin' used by Deceptor to inhibit recovery.", "Investigate the initial compromise vector (such as exposed RDP instances, spearphishing attachments, or vulnerable edge gateways) and enforce an immediate credential reset for all compromised Active Directory accounts.", "Restore critical assets and databases exclusively from verified, air-gapped, or immutable offline backups once the Deceptor binary and related persistence hooks are eradicated." ], "what_to_avoid": [ "Do not restart or power cycle infected systems prematurely; doing so destroys volatile RAM encryption keys and may trigger bootloader locking logic embedded in Deceptor.", "Avoid negotiating or paying the extortion demand without prior forensic evaluation and consultation with incident response specialists, as payment does not guarantee data recovery.", "Do not connect clean backup drives or external storage to the affected network until Deceptor eradication is completely verified." ], "target_platforms": [ "Windows 11", "Windows 10", "Windows Server 2022", "Windows Server 2019" ] }
