INSIGHT WEEKLY SECURITY NEWS LETTER-04-Aug-2017

Many organizations in Europe are affected by a ransom ware attack  “Petya”. The malicious software has spread through large firms including the advertiser WPP and Danish shipping and transport firm, leading to PCs and data being locked up and held for ransom.

Operations of one of the three terminals of India’s largest container port were affected as fallout of the Petya global ransom ware attack.

It is a second major global Ransom ware attack in last two months. As we said that it looks like   WannaCry, or WCry, has been stopped, or at least slowed, by the discovery of the so-called “kill switch.” However, is this just the eye of the storm that misleading calm between another onslaught. The code can be easily tweaked and the ransom ware unleashed again.

 

How does Peyta  RANSOMWARE works

The Petya ransomware takes the control of your computer and demands $300,paid in Bitcoin. The malicious software spreads rapidly across an organization once a computer is infected using the EternalBlue vulnerability in Microsoft Windows or using  Windows administrative tools. The malware tries one option and if it doesn’t work, it tries the next one.

It has another variant called golden eye. It goes a step further with two layers of encryption and locks up both your files as well as your system.

 

Immediate steps if you are affected by the ransom ware?

The ransomware infects computers and then waits about an hour before rebooting the system. While system reboots, you should switch off the system to prevent files from being encrypted and try to rescue files from system.

If the system reboots with the ransom note, don’t pay the ransom. The customer service email address has been shut down so there’s no way to get the decryption key to unlock your files anyway.

 

Immediately disconnect your PC from the internet, reformat the hard drive and reinstall your files from backup.
