Princess Locker V2 Virus – Infection Spread
The Princess Locker ransomware virus is possibly spread with an Exploit Kit if it follows suit of the original variant. Other methods for distributing the infection probably exist. It might spread through spam emails with an attachment. If you open such an attachment put in a suspicious e-mail, your computer could get infected. Social media networks and file-share services could also contain files like those if the cybercriminals decided to place them there. So, you should be very careful with the interactions you make on the Internet, such as when you click, download or open unknown files.
Below you can see the payload file that distributes the ransomware on VirusTotal:
The file is named ran.exe and is also present in other threat detection databases. Most antivirus programs detect it already, probably because of the similarity between its code and that of the original variant.
Princess Locker V2 Virus – Technical Data
Princess Locker is a ransomware cryptovirus. The ransomware has the same design, encryption mechanism and similar file distribution tactics as the original variant of the Princess Locker Ransomware Virus.
When Princess Locker ransomware finishes encrypting files it will place an image and a text document containing the ransom note with decryption instructions inside. The text document file bares one of the following names:
- =_THIS_TO_FIX_cRtG.txt
- =_THIS_TO_FIX_fyust.txt
- = _THIS_TO_FIX_aknT0I.txt
Below you can see the contents of one of these ransom note files:
The note states the following:
hpeECbqS CqXdyb qhBGhoryp
Your ID: U2WbVAYRDcaMQxxx
Your extension: cRtG
() Your files are encrypted!

If you click on the latter link, which are given on there you will land on the following page inside your browser:
You enter your ID and as you do that you will see a counter pop up showing that you have only a few days remaining to pay the initial price. That price is 0.0600 Bitcoins or around 545 US dollars. After that small time frame of a week expires, the demanded ransom will increase.
It is strongly NOT advised to pay any of the sums to the cybercriminals – if you pay them, there is absolutely no guarantee that you will decrypt your files. You will only end up financially supporting them with your money with their criminal endeavors.

Researchers have confirmed that files and their extension will not be changed. However, the extension that will be appended to files with five random characters will be placed as a secondary extension.
