DragonForce ransomware group exploited three vulnerabilities in SimpleHelp platform to breach systems of a major Managed Service Provider (MSP).
The attack involved deploying the ransomware via a legitimate SimpleHelp RMM instance operated by the MSP for their clients.
Sophos MDR researchers discovered the incident after spotting a suspicious installation of a SimpleHelp file on the MSP's system, leading to a ransomware infection.
DragonForce hackers utilized the MSP's RMM access to gather information on multiple customer estates managed by the MSP, including device names, configurations, users, and network connections.
