What is Princess ransomware? And how does it implement its attack?

Princess ransomware is a data-encrypting virus design to leave important files inaccessible to users. According to security experts, it might be related to the Princess Locker ransomware though the relationship between these threats is yet to be confirmed.
Once it infects a computer, it establishes a connection to a remote server where the crypto-malware sends the information it gathers about the system. After information gathering and transmission, Princess ransomware will download files from the remote server which are used to help it in implementing its attack. This implementation involves creating new system processes and repressing existing ones so it can control the computer and to prevent any program from interfering its attack. In addition, it also alters some sub-keys in the registry to make its presence persistent. Following these changes, the malware will scan the entire drive of the computer looking for files with these extensions:
.1cd, .3ds, .3gp, .accdb, .ape, .asp, .aspx, .bc6, .bc7, .bmp, .cdr, .cer, .cfg, .cfgx, .cpp, .cr2, .crt, .crw, .csr, .csv, .dbf, .dbx, .dcr, .dfx, .dib, .djvu, .doc, .docm, .docx, .dwg, .dwt, .dxf, .dxg, .eps, .htm, .html, .ibank, .indd, .jfif, .jpe, .jpeg, .jpg, .kdc, .kwm, .max, .mdb, .mdf, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdf, .pef, .pem, .pfx, .php, .png, .pps, .ppt, .pptm, .pptx, .psd, .pst, .pub, .pwm, .qbb, .qbw, .raw, .rtf, .sln, .sql, .sqlite, .svg, .tif, .tiff, .txt, .vcf, .wallet, .wpd, .xls, .xlsm, .xlsx, .xml
Princess ransomware uses the AES cryptography in encrypting files and appends the encrypted files with random 4-6 characters. It then creates the “Readme.txt” file which contains the following content:
“Hello. Your files have been encrypted.
For help, write to this e-mail: [email protected]
Attach to the letter 1-2 files (no more than 3 MB) and your personal key.
If within 24 hours you have not received a response, you need to follow the following instructions:

  1. a) Download and install TOR browser: https://www.torproject.org/download/download-easy.html.en
  2. b) From the TOR browser, follow the link: torbox3uiot6wchz.onion
  3. c) Register your e-mail (Sign Up)
  4. d) Write to us on e-mail: [email protected]

ATTENTION: e-mail ([email protected]) accepts emails, only with e-mail registered in the TOR browser at torbox3uiot6wchz.onion
Your personal key:
[redacted hex]”
Based on its ransom note, victims must contact the given email address ([email protected]) and pay the ransom on the given unique BTC wallet address. However, doing so is definitely not advised as these crooks might end up not giving you the decryptor after you pay the ransom. And besides, there are other alternative ways you can try to recover your files without spending any money.
How does Princess ransomware spread online?

Thus, you must always be cautious of downloading email attachments no matter who sent them.
