Of course, completely isolating the industrial network from adjacent networks is impossible, since transferring data between networks is required to perform a variety of important functions. Use of computers acting as bridges between several networks. There are typical industrial network configuration errors, which have led to WannaCry infections, according to our data:ġ. Since the industrial network is not directly connected to the Internet, and access is provided through the corporate network using NAT, a firewall and a corporate proxy server, which makes it impossible to infect such systems via the Internet.

The Wannacle malware spread across local networks and the Internet by exploiting the CVE-2017-0143 (MS17-010) vulnerability in components of the SMBv1 service (port TCP 445) in Windows operating systems. WannaCry ransomware (also known as WannaCrypt, Wana Decrypt, WCry and WanaCrypt0r), as you can deduce from its name, is a type of ransomware. In mid-May 2017, many companies around the world were attacked by the WannaCry network crypto variant.
