Revealerkeylogger
Overview
Executive Summary
Revealer Keylogger is a commercially available monitoring application (often marketed as "employee monitoring" or "parental control" software). However, due to its powerful, invisible surveillance capabilities, it is highly categorized as "Riskware" or a "HackTool" by enterprise security solutions. Threat actors frequently weaponize this legitimate software, deploying it silently on compromised hosts to act as an Info Stealer, capturing sensitive credentials and proprietary data without triggering standard malware heuristics.Infection Vector and Technical Capabilities
Revealer Keylogger must be intentionally installed. In a malicious scenario, it is either installed by a malicious insider with physical access or deployed remotely by an attacker who has already achieved administrative privileges on the endpoint. Once deployed, it utilizes deeply embedded monitoring techniques:- API Hooking and Surveillance: The application deeply hooks into the Windows API to record every keystroke pressed by the user, regardless of the application in focus. It also takes periodic, hidden screenshots of the user's desktop.
- Extreme Stealth Mode: The defining feature of Revealer Keylogger is its "stealth mode." When activated, it completely hides its processes from the standard Windows Task Manager, removes its entries from the Windows Startup registry keys, and operates invisibly in the background.
- Automated Data Exfiltration: The software can be configured to automatically compile the harvested keystroke logs and screenshots and exfiltrate them silently via email (SMTP), FTP upload, or over a local network share to a designated attacker-controlled location.
Threat Assessment
The unauthorized presence of Revealer Keylogger on a corporate endpoint is a critical security breach. It guarantees the compromise of all passwords typed on that machine, leading to unauthorized access to enterprise systems, potential privilege escalation, and severe data leakage.Incident Response and Remediation
- Contextual Verification: First, determine if the installation was authorized (e.g., a sanctioned insider threat investigation by HR/Legal). This is rare, as enterprise monitoring is usually handled by centralized DLP solutions, not standalone keyloggers.
- Assume Total Credential Compromise: If unauthorized, immediately assume all user credentials, VPN tokens, and sensitive data processed on that machine have been compromised. Initiate a mandatory, global password reset for the affected user(s).
- Complete System Wipe: Because commercial keyloggers are designed to deeply hide themselves and resist removal, attempting to manually uninstall the software is insufficient. A complete bare-metal wipe and re-image of the compromised endpoint is required.
Known aliases
Threat reports may refer to this family under multiple names:
MITRE ATT&CK Techniques
This family has been observed using the following ATT&CK techniques: T1056.001 T1115 T1056.002
Tactical Mitigations
Based on the techniques used by this family, consider the following defensive strategies:
- T1056.001: Implement Endpoint Detection and Response (EDR) to monitor for suspicious API calls related to keystroke interception. Enforce Multi-Factor Authentication (MFA) to render stolen passwords useless.
- T1056.002: Monitor for unauthorized keylogging, screen capturing, or web browser API hooking. Deploy EDR to detect API hooking.

Frequently Asked Questions
How do I remove the Revealerkeylogger Advanced_Threat from Windows?
Manual removal of Revealerkeylogger 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.
Is Revealerkeylogger a virus or a Advanced_Threat?
Revealerkeylogger is classified as a Advanced_Threat. Unlike traditional viruses that infect files, modern malware like Revealerkeylogger typically operates as a standalone payload designed to compromise systems, steal data, or deploy secondary stage implants.
What are the main symptoms of a Revealerkeylogger infection?
Symptoms of Revealerkeylogger 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.
