A reported Free Download Manager supply chain attack redirected Linux users to a malicious Debian package repository that installed information-stealing malware.
The malware used in this campaign establishes a reverse shell to a C2 server and installs a Bash stealer that collects user data and account credentials.
Kaspersky discovered the potential supply chain compromise case while investigating suspicious domains, finding that the campaign has been underway for over three years.
And via a website too. That’s like pushing a car. One of the main strengths of Linux are open repositories, maintained by reputable sources and checked by thousands of reputable people. Packages are checksummed and therefore unable to be switched by malicious parties. Even the AUR is arguably a safer and more regulated source. And it’s actually in there.
