fix-your-malware-problem-sensorstechforumThe AMBA virus, notorious for the fact that it encrypts the databases of websites with .amba file extension added to them has appeared on the radar. The crypto-virus directly attacks the “Index Of” belonging to websites whose servers are not properly secured. Its ransom note is written entirely in Russian language, and its variants have been reported to exist since the year 2013.

AMBA Ransomware’s Distribution Scheme

Since Amba ransomware attacks mostly servers, it may use different approach instead of the convention massive spam campaign. For example, if the server is located in a network with other devices, the virus may use a worm to spread across the network to other devices. In addition to this, the creators of Amba may also send malicious URLs directly on the website as spam comments. Such web links may redirect to other URLs which may cause the infection via a drive-by-download. Another possibility is a targeted attack with a Trojan.Downloader, which can download AMBA ransomware’s malicious files, directly on the server.

AMBA Ransomware Viewed In Depth

As soon as it is executed on a given machine, AMBA begins to encipher files that are web server related, for example they may have the following extensions:

After encrypting the databases of websites, the AMBA virus adds its own “trademark” – the AMBA file extension. Files of websites encrypted by AMBA look like the following image, reported by Amigo A – malware researcher at id-ransomware.blogspot.bg:

index-amba

After encrypting the files on the website of the server, AMBA ransomware uses a text file to notify users that their files have been encrypted. The file is named ПРОЧТИ_МЕНЯ.txt and has the following message in it:

“——————————————————————————–

——————————————————————————–
