A cyberespionage and hacking campaign tracked as 'RedClouds' uses the custom 'RDStealer' malware to automatically steal data from drives shared through Remote Desktop connections.

Suspected state-sponsored threat actors have trojanized the official Windows desktop app of the widely used 3CX softphone solution, a number of cybersecurity companies began warning on Wednesday. 3CX offers a Windows, macOS, Linux, Android and iOS version of the app, a Chrome extension, and the PWA version so the software can be also used via any browser.
3CX said it's working on a software update for its desktop app after multiple cybersecurity vendors sounded the alarm on what appears to be an active supply chain attack that's using digitally signed and rigged installers of the popular voice and video conferencing software to target downstream customers."The trojanized 3CX desktop app is the first stage in a multi-stage attack chain that pulls ICO files appended with Base64 data from GitHub and ultimately leads to a third-stage infostealer DLL," SentinelOne researchers said.
A digitally signed and trojanized version of the 3CX Voice Over Internet Protocol desktop client is reportedly being used to target the company's customers in an ongoing supply chain attack. 3CX is a VoIP IPBX software development company whose 3CX Phone System is used by more than 600,000 companies worldwide and has over 12 million daily users.
