Sophos researchers discovered a cyberattack where DragonForce ransomware exploited three vulnerabilities in SimpleHelp to breach an MSP and its customers.
The vulnerabilities (CVE-2024-57727, CVE-2024-57728, and CVE-2024-57726) allowed unauthorized access, arbitrary file downloads, uploads, and privilege escalation.
Arctic Wolf observed a targeted campaign exploiting these vulnerabilities shortly after their disclosure, potentially compromising devices using SimpleHelp client software.
Sophos found that the attackers used a legitimate SimpleHelp instance to deploy malicious software, compromising multiple customers, with some successfully defended by Sophos MDR and XDR services.
