Updated Advice for Petya Ransomware Outbreak

Urgent Threat Update Regarding Petya 
Ransomware Outbreak

Please be alerted that a new strain of ransomware is spreading fast based upon Petya which renders servers and machines useless. Comments on VirusTotal indicate the usage of the EternalBlue exploit but this has not yet been confirmed but is the likely entry point. The ransomware clears the windows event log using Wevtutil, writes a message to the raw disk partition and shuts down the machine.

Further companies have been affected today and advice has now been amended.  Please see the advisory below, point 3 is of particular importance.
Until further information is available we urge all our clients to:

1)   Test for back-ups today
2)   Make sure all patches have been deployed fully.  See below for the advice given by Microsoft in May regarding Wannacry and check that it has been implemented:

3) If affected, Customers are now advised to unplug the machines from the network and power down if infected.
Do Not switch the power back on as files may be recoverable if the encryption process has not yet begun. 
Attempting to pay the ransom does not work as the decryption process does not start.  The payment email address has been disabled.

4)    Advise all users to be extra vigilant for phishing attacks. 
5)     Call ZeroDayLab if they have any further concerns.
