Disc Soft Limited, the maker of DAEMON Tools Lite, confirmed that the software had been trojanized in a supply chain attack and released a new, malware-free version. "Within less than 12 hours of identifying the issue, we were able to implement a solution. Based on our current findings, the issue was limited to the free DAEMON Tools Lite version and did not affect any of our other products," Disc Soft told BleepingComputer. "We have not identified evidence supporting claims that all DAEMON Tools users were impacted, and at this stage, we are not in a position to confirm any impact on paid versions customers. Our current analysis indicates that DAEMON Tools Pro and DAEMON Tools Ultra were not affected and absolutely safe." In a separate statement published earlier today, Disc Soft also said it has secured its infrastructure. Still, it has yet to attribute the attack to a specific threat actor or share additional information about the breach, including the attack vector used to access its systems, as it continues to investigate the incident. "Following an internal investigation, we identified unauthorized interference within our infrastructure. As a result, certain installation packages were impacted within our build environment and were released in a compromised state. Version 12.6 of DAEMON Tools Lite, which does not contain the suspected compromised files, was released on May 5." the company said. "Users of other DAEMON Tools products, including paid versions of DAEMON Tools Lite, DAEMON Tools Ultra, and DAEMON Tools Pro are not affected by this incident and can continue using their software as usual." Users who downloaded or installed DAEMON Tools Lite version 12.5.1 (free) since April 8 are advised to uninstall the app, run a full system scan using security or antivirus software, and install the latest version of DAEMON Tools Lite (12.6) from the official website. Disc Soft has removed the trojanized version, which is no longer supported, and now displays
