Lazarus Uses ManageEngine Flaw to Deploy QuiteRAT in European Infrastructure Breach

· Original article ↗

Summary

Cisco Talos reports that Lazarus exploited ManageEngine ServiceDesk CVE-2022-47966 to compromise a European internet backbone provider and deploy QuiteRAT, a compact Qt-based remote access trojan related to MagicRAT.

Key points

  • Talos observed Lazarus exploiting ManageEngine ServiceDesk CVE-2022-47966 five days after public proof-of-concept exploits appeared.
  • The campaign compromised a European internet backbone provider and also targeted healthcare entities in Europe and the United States.
  • QuiteRAT gathers system information and lets its operators run commands through a command-and-control server.
  • The malware uses Qt libraries and is smaller than MagicRAT; Talos assesses it is a derivative of that implant.
  • QuiteRAT lacks built-in persistence; operators can direct it to create a Windows service for continued operation.
  • Talos published a malware hash and network indicators of compromise.

Article Details

Attack Vectors
  • Exploited CVE-2022-47966 in ManageEngine ServiceDesk to gain initial access and deploy QuiteRAT.
  • Used cURL to download a malicious binary from an attacker-used URL; the Java runtime process then executed it.
  • QuiteRAT communicates with command-and-control servers over HTTP GET, receives commands and payloads, and can execute Windows commands through a child cmd.exe process.
  • Persistence was established by issuing a command to create an automatically starting Windows service.
Defensive Notes
  • Cisco Talos says Qt-based malware can be harder for human analysts to inspect and may be less reliably detected by machine-learning and heuristic methods.
  • The article recommends using Cisco Secure Endpoint, Cisco Secure Web Appliance, Cisco Secure Email, Cisco Secure Firewall, Cisco Secure Malware Analytics, Umbrella, Cisco Duo, and current Snort Subscriber Rule Set rules to help prevent, detect, or block related activity.
