Petya Ransomware encrypts the MBR

The Dell Sonicwall Threat Research team has received reports of yet another ransomware called Petya. Over the past year, Ransomware has proven to be an inceasingly lucrative business for cybercriminals and has become very widespread that victims have resorted to paying to get their data back. Petya is no different, but instead of just encrypting files it overwrites the system's master boot record (MBR) effectively locking the victim out and rendering the machine unusable unless payment is made.
Infection Cycle: 

Upon execution, Petya replaces the boot drive's MBR with a malicious loader which will cause Windows to crash. On reboot, it will display a fake CHKDSK screen. 
 

The victim is then greeted with a flashing skull. 
 

After pressing any key, the instructions on how to pay to get their data back is then displayed. 

 

At this point, the victim is locked out of their machine and renders it useless. Rebooting into safe mode is also not possible. Victims can reformat their computers but will obviously lose all of their data. 

Below are the screenshots from the cybercriminal's well crafted website on the onion network where further instructions are given on how to submit payment in bitcoins. It appears that the group behind Petya Ransomware is calling themselves "Janus Cybercrime Solutions" and are demanding victims to send them 0.95865300 Bitcoins or an equivalent to $395 with the current exchange rate.

Because of the prevalence of these types of malware attacks, we urge our users to back up their files regularly. 

So it is time to check update for your Gateway Security/End point Security now to prevent this threat!

From the internal network, attempt to ping the management IP address. If you cannot connect to the internal interface, verify the IP configuration of the PC and make sure the cables are connected and all switches and other devices on the network are powered on a
