#CyberSecurityPulse: Last Update About Bad Rabbit Ransomware

Tuesday, October 31, 2017

On October 24th infections about a ransomware called Bad Rabbit began to spread. Less than one day, it has been targeting organizations and consumers, mostly in Russia, Ukraine, Turkey, Bulgaria and the United States.

The ransomware dropper was distributed with the help of drive-by attacks. While the target is visiting a legitimate website, a malware dropper is being downloaded from the threat actor’s infrastructure. No exploits were used, so the victim would have to manually execute the malware dropper, which pretends to be an Adobe Flash installer.

However, Bad Rabbit uses the EternalRomance exploit as an infection vector to spread within corporate networks. The same exploit was used in the ExPetr. This been a targeted attack against corporate networks, using methods similar to those used during the ExPetr attack. The code analysis showed a notable similarity between the code of ExPetr and Bad Rabbit binaries.

According to Kaspersky, analyzing the sample, it looks like the criminals behind this malware are fans of the famous books and TV show series Game Of Thrones. Some of the strings used throughout the code are the names of different characters from this series. They have also discovered that files encrypted by Bad Rabbit can be recovered with following specific procedures: "We have discovered that Bad Rabbit does not delete shadow copies after encrypting the victim’s files. It means that if the shadow copies had been enabled prior to infection and if the full disk encryption did not occur for some reason, then the victim can restore the original versions of the encrypted files by the means of the standard Windows mechanism or 3rd-party utilities".
