Wannacry Ransomware 2.0

For those unaware, WannaCry is an insanely fast-spreading ransomware malware that leverages a Windows SMB exploit to target a computer running on unpatched or unsupported versions of Windows and servers and then spread itself like a worm to infect other vulnerable systems in the internal network.

Wannacry RansomwareOne was those victims was seemingly Telefónica, a large Spanish telecommunications company, according to Spanish publication El Mundo. Judging by the report, Telefónica told employees to shut down their computers, and 85 percent were allegedly infected with a version of WannaCry.

“Ooops, your files have been encrypted!” the message on Telefónica machine’s allegedly reads, according to a photo published by El Mundo.

That warning is largely identical to one allegedly presented on screens in at least one UK hospital on Friday.
