A supply chain attack compromised the official installation packages of DAEMON Tools Lite (Windows versions 12.5.0.2421 through 12.5.0.2434), distributed from the legitimate website daemon-tools.cc between approximately April 8, 2026, and May 5, 2026. Attackers gained unauthorized access to the vendor's (AVB Disc Soft) build or distribution infrastructure and trojanized three binaries: DTHelper.exe, DiscSoftBusServiceLite.exe, and DTShellHlp.exe. These files were digitally signed with the legitimate AVB Disc Soft code-signing certificate, allowing the malicious installers to appear trustworthy and bypass signature-based detection.

Supply chain compromise of DAEMON Tools Lite for Windows delivered trojanized installers through the legitimate vendor website daemon-tools.cc from April 8 to May 5, 2026. Attackers compromised AVB Disc Soft's build infrastructure and injected malicious code into three binaries (DTHelper.exe, DiscSoftBusServiceLite.exe, DTShellHlp.exe), all signed with the vendor's legitimate code-signing certificate. …

RemediationAI
Within 24 hours: Identify all endpoints with DAEMON Tools Lite installed; cross-reference against version history to confirm presence of 12.5.0.2421-12.5.0.2434; isolate affected systems from production networks and disable auto-update on remaining DAEMON Tools Lite instances. Within 7 days: Perform forensic analysis on all affected systems for indicators of malware persistence, lateral movement, and credential theft; assume breach and initiate threat hunting for abnormal process execution, network connections, and privilege escalation attempts; notify threat intelligence and incident response teams. …
