Today, CISA released Cybersecurity Advisory: Ransomware Actors Exploit Unpatched SimpleHelp Remote Monitoring and Management to Compromise Utility Billing Software Provider.

This advisory is in response to ransomware actors targeting customers of a utility billing software provider through unpatched vulnerabilities in SimpleHelp Remote Monitoring and Management (RMM).

This incident is part of a broader trend of ransomware actors exploiting unpatched versions of SimpleHelp RMM since January 2025.

SimpleHelp versions 5.5.7 and earlier contain multiple vulnerabilities, including CVE-2024-57727, a path traversal vulnerability. Ransomware actors likely exploited CVE-2024-57727 to access downstream customers’ unpatched SimpleHelp RMM, resulting in service disruptions and double extortion incidents.

CISA added CVE-2024-57727 to its Known Exploited Vulnerabilities Catalog on February 13, 2025.

Organizations using SimpleHelp RMM should: 

  • Search for evidence of compromise,
  • Apply the mitigations outlined in the advisory such as patching CVE-2024-57727 and/or implementing appropriate workarounds to prevent or respond to confirmed or potential compromises, and
  • Follow CISA’s Known Exploited Vulnerabilities Catalog.
