Last Friday was an enjoyable day… (no, it wasn’t.)
I had yet another customer site get infected with a ransomware virus. When you have a virus infection that affects a few computers, it can disrupt business, particularly small business.
In this case, it was a single workstation that was infected with a variant of the Cryptowall virus. It appears that the user had clicked on an email or a website disguised as a sales order that contained a link to an executable which contained the virus. The virus package included a Tor client so that it could communicate with its perpetrators.
