What a virus

According to the Motherboard edition, the WanaCrypt0r virus has an “incredible spread rate”. For distribution across organizations’ local networks, it uses the Eternal Blue vulnerability, which was previously used by the US National Security Agency. Using this protocol exploit to share SMB files, a virus from one infected computer can infect others on the same network.

The authors suggested that the virus could be created by hackers based on one of these tools. The journalist Sam Gad Jones wrote about this on Twitter.

“Hackers used an American exploit known as“ eternal blue ”, published by [hackers] Shadow Brokers, intelligence sources told FT.

Kevin Beaumont, a security specialist, wrote about using a worm called eternal blue

“Confirmed – wcry, spreading throughout Europe, used the” eternal blue “”

Kaspersky Lab specialists confirmed that the virus uses a previously discovered Windows vulnerability, which Microsoft promised to close in March 2017. According to the company, 75 thousand attacks were recorded in 74 countries around the world. Most of all – in Russia.

According to The New York Times, part of the responsibility for the attack lies with a group of hackers Shadow Brokers. Its members published an exploit from data stolen from Microsoft.
