ThreeAM claims to have leaked data from iss-na.com

The threat actor known as ThreeAM has listed iss-na.com on their leak site. According to the announcement made on May 25, 2025, the group claims to have published data belonging to the organization. This development follows a period of alleged unauthorized access that the group suggests occurred earlier in the year.

Ransomware groups often utilize leak sites to exert pressure on their victims. These platforms serve as a public stage where threat actors post announcements regarding their targets. In many instances, these groups employ a tactic known as double extortion, where they not only encrypt an organization's systems to disrupt operations but also steal sensitive information to use as leverage for ransom demands. By threatening to release stolen data publicly, attackers aim to maximize the pressure on the victim to comply with their demands.

Details of the alleged incident

The announcement from the ThreeAM group suggests that the organization was subject to a cyber incident on February 18, 2025. While the leak site announcement was posted in May, the group claims the initial breach took place several months prior. The threat actor has created a dedicated leak page specifically for this incident, claiming that the organization's data has been released to the public.

Regarding the specifics of the breach, the listing does not provide details on the volume or nature of the information involved. The listing names no data types.

For organizations operating within the professional services sector, maintaining robust cybersecurity postures is essential.
