Ranstop blocks PrincessLocker Evolution ransomware

Test subject – PrincessLocker Evolution ransomware

PrincessLocker first emerged in 2016, and since then, several versions and variants were released. We covered one of these in this article.

This one is called “Evolution” and it was quickly advertised as a RaaS (ransomware as a service) by the malware developers. This means that anybody willing to pay some amount of money can personalize and distribute it as another (similar) ransomware, including the addition of crypto-miners and exploits. This makes PrincessLocker even more dangerous.

PrincessLocker Evolution ransomware test facts

The new version adds new communication protocols with the command & control servers, changing the classic HTTP with UDP (which is faster and more reliable) while sending personal information, like username, installed software and other sensitive data. Encryption is also different from previous versions, as this one will encrypt only the first part of the files. This method makes it very fast, as a smaller data quantity is altered. The files are destroyed just as well, of course. The ransom note is dropped in all attacked folders, in multiple formats, including HTML, and the desktop background is replaced with the ransom note. The encrypted files will receive a new, randomly generated extension, making the identification of this ransomware somewhat more difficult. Reports say that the ransom starts at 0.12 BTC (~$800), and as usual, we will never recommend paying.
