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.
Back in the day when most stuff was on FTP and HTTP and your connection was crap and could drop at any time, you’d use a download manager to smooth things along. It could resume downloads when connection dropped, it could keep a download going for days on end and resume as needed, and it could abusing the bandwitdh limitations of the source site by using multiple parallel connections that pulled on different file chunks. In some ways it was very similar to how we use BT today.
It was also useful to keep a history of stuff you’d downloaded in case you needed it again, manage the associated files etc.

Also for files which had multiple different mirror sites you could download chunks from multiple mirrors concurrently which would allow you to max out your bandwidth even if individual mirrors were limiting download speeds.
