Cryptowall, malware, virusThe BBC is reporting a new worldwide ransomware attack is currently underway. Victims have thusfar been in reported at least 74 different countries. The UK’s National Health Services, Spain’s largest telecom provider, Telefónica, and FedEx have all reported being hit by this new variant called WannaCry.

While the ransom requested by the perpetrators is currently only $300 worth of bitcoin, the damage in productivity is always much more difficult to calculate. Plus, there’s no guarantee that paying the ransom will result in your files being decrypted. The original source for this variant is thought to use the ETERNALBLUE exploit, which was originally developed by the fine folks at the NSA. The exploit takes advantage of a vulnerability in Microsoft’s SMB protocol.

What’s different about this variant of ransomware is that once a machine is infected inside an organization’s network, the program will actually hunt down other vulnerable machines and infect them as well. This makes it very different and very dangerous compared to previous malicious programs like this.
