Incident responders, s'il vous plait: Invites lead to odd malware events
Summary
A phishing campaign has been observed where attackers are sending out invitations that, when accepted by recipients, lead to the installation of remote management tools (RMMs) on victim systems. While the campaign has successfully installed RMMs, it has not yet resulted in significant data theft or further malicious activity, leading researchers to question if it's a test by a threat actor or an 'access-as-a-service' attack.
IFF Assessment
This campaign indicates a new phishing vector leading to the deployment of potentially harmful tools, representing a new tactic for threat actors.
Defender Context
Defenders should be vigilant about unusual invitation emails and educate users on the risks of accepting unexpected requests, especially those that might lead to software installations. This highlights the evolving nature of phishing campaigns that leverage social engineering to deploy initial access tools for future exploitation.
