A destructive ransomware program deletes files from web servers and asks administrators for money to return them, though it’s not clear if attackers can actually deliver on this promise.
Dubbed FairWare, the malicious program is not the first ransomware threat to target Linux-based web servers, but is the first to delete files. Another program called Linux.Encoder first appeared in November and encrypted files, but did so poorly, allowing researchers to create recovery tools.
After attackers hack a web server and deploy FairWare, the ransomware deletes the entire web folder and then asks for two bitcoins (around US$1,150) to restore them, Lawrence Abrams, the founder of tech support forum BleepingComputer.com, said in a blog post.
In the ransom note left on the server, attackers claim that before being deleted from the targeted server, the files were first encrypted and uploaded to another server under their control.
