What is the STX RAT malware distributed through CPUID's compromised downloads?

STX RAT is a remote access trojan (RAT) that was distributed through compromised downloads of CPU-Z and HWMonitor from the official CPUID website during a breach in April 2024. This malware provides attackers with extensive control over infected systems, allowing them to execute commands, steal sensitive data, monitor user activity, and potentially deploy additional payloads. The STX RAT is particularly dangerous because it was delivered through trusted software sources, making it harder for users to detect. It operates by establishing a backdoor connection to command-and-control servers, enabling remote administration without the user's knowledge. This incident highlights the risks of supply-chain attacks, where attackers target legitimate software distribution channels to spread malware. Users who downloaded CPU-Z or HWMonitor from CPUID's website between April 9 and 10, 2024, should scan their systems with updated antivirus software and consider reinstalling the software from verified sources to mitigate potential infections.
