    Hola Browser for Windows supply chain compromise delivers a Monero miner

    Initial Disclosure

    Hola Browser for Windows was compromised in a supply chain attack that installed an undeclared executable named me.exe under C:\Program Files\Hola\; researchers found signs that it was a Monero cryptocurrency miner, and the payload added a Windows Defender exclusion rule, copied itself as HolaMonitorService.exe, created the hola_monitor_svc service, and ran when the computer was idle. Hola said it rebuilt its distribution pipeline, strengthened code-signing verification, and tightened access controls and monitoring, while reporting that about 0.1% of users were affected and that there was no evidence of user data access or theft.
