Luna Moths’s most modern assaults cling impersonating IT give a enhance to by email, faux websites, and contact calls, and depend fully on social engineering and deception, and not utilizing a ransomware deployment viewed in any of the cases.

“As of March 2025, EclecticIQ assesses with high confidence that Luna Moth has likely registered at least 37 domains through GoDaddy to support its callback-phishing campaigns,” reads the EclecticIQ document.

“Most of these domains impersonate IT helpdesk or support portals for major U.S. law firms and financial services firms, using typosquatted patterns.”

The most modern process spotted by EclecticIQ begins in March 2025, focused on U.S.-based organizations with malicious emails that cling faux helpdesk numbers recipients are urged to name to ranking to the bottom of non-existent concerns.

A Luna Moth operator solutions the name, impersonating IT workers, and convinces the victim to set up some distance off monitoring & administration (RMM) gadget  from faux IT aid desk websites that presents the attackers some distance off ranking entry to to their machine.

Büyükkaya feedback on the stealth of these assaults, noting that they cling no malware, malicious attachments, or links to malware-ridden websites. The victims merely set up an RMM tool themselves, pondering they are receiving aid desk give a enhance to. 

As the enterprise normally makes disclose of these RMM instruments, they construct now not seem like flagged by safety gadget as malicious and are allowed to maneuver.

Indicators of compromise (IoCs), including IP addresses and phishing domains that need to peaceable be added to a blocklist, are on hand at the bottom of EclecticIQ’s document.

As an alternative of the domains, additionally it is often recommended to center of attention on about restricting the execution of RMM instruments that need to now not vulnerable in an organization’s environment.
