Deceptor
Table of Contents
Overview
Executive Summary
Deceptor (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.Infection Vector and Technical Capabilities
Deceptor 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. Once installed, the software employs highly aggressive extortion tactics:- Deceptive UI and Scareware Tactics: The application is meticulously designed to mimic the graphical user interface of legitimate Windows components or well-known AV brands. It launches automatically on boot and invariably reports numerous critical (but non-existent) security threats.
- System Hostage (Locking): Aggressive variants of Deceptor employ system-locking tactics. They may constantly overlay the screen with warnings, disable the Windows Task Manager, or block the execution of legitimate executable files (claiming they are "infected"), effectively holding the user's workflow hostage until they pay.
- Persistent Nagging and Fake Alerts: The software establishes persistence via registry `Run` keys and scheduled tasks, generating fake system tray balloons and pop-ups demanding credit card information.
Threat Assessment
While 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.Incident Response and Remediation
- Safe Mode Execution: Due to the aggressive screen-locking and self-defense mechanisms that block executable launches, it is almost always necessary to boot the infected machine into Windows "Safe Mode with Networking" to prevent the scareware from launching before attempting removal.
- Targeted Anti-Malware Scan: Utilize a reputable enterprise anti-malware solution (specifically tuned for Rogue Software and Scareware removal, such as Malwarebytes) to scan for and remove the deeply embedded registry keys and scheduled tasks associated with the PUP.
- Financial Dispute: If the user was tricked into purchasing the fake software, advise them to immediately contact their credit card company to dispute the fraudulent charge.

Modern threat detection requires multi-layered rule engineering. We classify detections into three operational tiers based on signal fidelity:
Tier 1 Primitive Artifact Rule (Fast Triage)

rule MALWARE_WIN_DECEPTOR_T1_ARTIFACT {
meta:
description = "Tier 1 Primitive Artifact: Raw string matches for Deceptor"
tier = "T1 - Primitive Artifact"
confidence = "Low-Medium (Fast Triage)"

strings:
$s1 = "deceptor" ascii wide nocase
$s2 = "rogue.deceptor" ascii wide nocase
$s3 = "pup.fakeav" ascii wide nocase
$s4 = "scareware.win32" ascii wide nocase
condition:
uint16(0) == 0x5a4d and any of them
}Tier 2 Behavioral Context Rule (Process Chains & Sigma)
Tracks parent-child process anomalies and suspicious scripting telemetry. Resilient against file renames.

}Containment & Response Steps
Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.
- 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
Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.
- 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.

Frequently Asked Questions
What is Deceptor and what threat category does it belong to?
Deceptor is classified as a Ransomware. Documented across security telemetry, it is engineered to execute unauthorized operations, establish persistent footholds on target endpoints, and facilitate malicious campaigns targeting enterprise and individual environments.
How does Deceptor establish persistence and evade defensive controls?
Deceptor typically establishes persistence through registry run keys, scheduled tasks, or service installations, while evading signature-based antivirus solutions through code obfuscation, memory injection, or anti-analysis sandbox checks.
What are the essential incident response steps for mitigating a Deceptor compromise?
Security teams responding to Deceptor should immediately isolate affected endpoints from the network, perform memory triage to capture volatile forensic artifacts, audit registry and startup persistence mechanisms, revoke exposed user credentials, and restore systems from verified, clean backups.
What cryptographic algorithms and file targeting techniques does Rogue.Deceptor employ during execution?
Rogue.Deceptor typically leverages hybrid cryptographic architectures combining symmetric stream or block ciphers (such as AES-256 or ChaCha20) for rapid file encryption with asymmetric algorithms (such as RSA-2048 or Curve25519) to securely protect the session keys. It aggressively targets sensitive file extensions including corporate documents, databases, virtual disks, and backups while systematically executing commands to delete Volume Shadow Copies (vssadmin delete shadows /all /quiet) and disable system recovery options.
Are decryptors available for Rogue.Deceptor, and what is the recommended recovery procedure?
Decryption availability for Rogue.Deceptor depends on whether security researchers or law enforcement (such as the No More Ransom initiative) have recovered the master private keys or discovered flaws in its key generation routines. 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.
How do I remove Deceptor from Windows?
Manual removal of Deceptor is highly discouraged as it may leave persistence mechanisms intact. We recommend disconnecting the device from the internet and utilizing a professional incident response service or enterprise-grade EDR software to conduct a full forensic sweep.
What are the main symptoms of a Deceptor infection?
Symptoms of Deceptor can include unexpected system slowness, unauthorized outbound network traffic to unknown IP addresses, disabled security software, and suspicious background processes running from AppData or Temp directories.
