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.
Now I need to know who the hell has installed Free Download Manager on Linux.
The same people that would have given that poor nigerian prince their bank account details
Or what is Free Download Manager
I once did.
I’ve installed and used it, and still do.
My internet connection is not that reliable, and when I download big files that are not torrents (say >1000 MB) and the download is interrupted because of internet disconnect, Firefox often has trouble getting back to it while FDM doesn’t.
FDM also lets me set download speed limits, which means I can still browse the internet while downloading.
It’s not my main tool for downloading stuff, but it has its uses.
The article mentions how to check for infection:
If you have installed the Linux version of the Free Download Manager between 2020 and 2022, you should check and see if the malicious version was installed.
To do this, look for the following files dropped by the malware, and if found, delete them:
/etc/cron.d/collect /var/tmp/crond /var/tmp/bs
“Non-free download manager”
Finally linux is getting popular enough to make viruses. Yay?. Insert gru meme here

I had to essentially read the same thing four times before there was any new information in this post. Not sure if that’s a Jerboa thing or what, but probably could have been avoided.
Yeah I agree, sorry about that. I thought that the body-text field was mandatory to fill in, so I used the introductory paragraph from the article so as not to editorialize.
That’s what you get from not using

What the hell is Free Download Manager?
Glad am not using a deb based distro.
