A new cryptovirus called “B0r0nt0K” has been putting Linux and possibly Windows Web servers at risk of encrypting all of the infected domain’s files. The new ransomware threat and the ransom of 20 bitcoins — about $ 75,000 — first came to light last week in a forum post. A client’s website had all its files encrypted and renamed with the .rontok extension appended to them, the forum user indicated.
The website was running on Ubuntu 16.04. The B0r0nt0K ransom note is not displayed in a text format or in the message itself, based on the report.
