Users of Windows need to be notified ASAP of a new ransomware strain and take immediate measures to patch.
Specifically, on May 12, 2017 a new strain of the Ransom.CryptXXX (WannaCry) strain of ransomware began spreading widely impacting a large number of organizations, particularly in Europe.
Wcry is demanding ransom fees to be paid. The messages left on the screen say files will remain encrypted. It’s not yet clear if there are flaws in the encryption scheme that might allow the victims to restore the files without paying the ransom.
If you have yet to install the Microsoft fix—MS17-010— you should do so immediately.
You should also be extremely suspicious of all e-mails you receive, particularly those that ask the recipient to open attached documents or click on Web links. If you have seen nonstandard activity and believe your customers’ information may have been exposed, please contact support.
