  • Uses sophisticated obfuscation techniques
  • Often delivers ransomware payloads

HOW DOES IT INFECT YOUR DEVICE?

Infection process

SocGholish spreads through "drive-by downloads," where malware is installed without your knowledge after visiting a compromised or malicious website.

INFECTION PROCESS:

  1. Visiting a Compromised Website: Hackers inject malicious JavaScript code into legitimate websites.
  2. Fake Update Prompts: The malware displays convincing pop-ups claiming your browser needs an update.
  3. User Action: Clicking the "update" button downloads a malicious .zip or .js file.
  4. Redirection Tactics: Uses sophisticated methods like Keitaro TDS to send users to malicious sites.

WHAT DOES IT DO TO YOUR SYSTEM?

Information Theft

Collects your IP address, browser type, and system details using Windows Management Instrumentation (WMI). This data is sent to attackers' servers.

Additional Malware

Deploys tools like Cobalt Strike, NetSupport, AsyncRAT, or ransomware like LockBit and RansomHub to control your device or lock your files.

Evasion Techniques

Uses obfuscated code and downloads payloads in small, encrypted chunks to avoid detection. May remain dormant before activating.

BUSINESS IMPACT

For organizations, SocGholish can cause data breaches, network-wide infections, and significant operational disruptions. The financial and reputational damage can be severe.
