Hacker have demanded 100BTC for the private key, by which all Encrypted files can be open.
On Friday, The San Francisco Examiner reported that riders of SFMTA’s Municipal Rail or “Muni” system were greeted with handmade “Out of Service” and “Metro Free” signs on station ticket machines. The computer terminals at all Muni locations carried the “hacked” message: “Contact for key (firstname.lastname@example.org),” the message read.
Messages sent to the attacker’s email@example.com account show a financial relationship with at least two different hosting providers. The credentials needed to manage one of those servers were also included in the attacker’s inbox in plain text, and my source shared multiple files from that server.Source: KerbsonSecurity
