If your files have a .crptrgr extension added to them, the reason for that is CryptoRoger – a modern ransomware also known as a crypto-virus. What it does is it infects users via spam campaigns of malicious URLs or files. After infection, the virus uses a strong cipher called Advanced Encryption Standard which is 256 bits in strength to scramble the files of its victims and extort them for 0.5 bitcoins (~300 USD) for the restoration of access to their files.
We strongly advise you NOT to pay any ransom money to cyber-criminals and instead attempt other methods to revert the files encrypted by them after removing this virus using the instructions in this article.

CryptoRoger Ransomware – Infection Strategy
To infect the maximum amount of users possible, CryptoRoger uses a .vbs script which automatically runs. This script may be downloaded onto the victim’s computer via several different methods:
- Drive-by downloads.
- Via Exploit Kits.
- By using a malicious .js (JavaScript).
- Via being directly attached to spam e-mail messages.
Users complain in security forums that they might have been infected by clicking on malicious e-mail messages, which they believed were legitimate.
CryptoRoger Ransomware Virus – Detailed Analysis
Once it has been dropped on your computer, CryptoRoger contains the following malicious files, located in various Windows directories:
- %AppData%\Microsoft\Windows\Start Menu\Programs\Startup\x.vbs
- %AppData%\bg.jpeg
- %AppData%\files.txt
- %AppData%\keys.dat
- %UserProfile%\CryptoRoger\{CryptoRoger’s primary executive}.exe
After dropping the files, CryptoRoger starts modifying heavily the Windows Registry Editor, by creating a key named “CryptoRoger” along with several different values in them:
- HKCU\Software\CryptoRoger\
- HKCU\Software\CryptoRoger\AESFORUPRIVATE
- HKCU\Software\CryptoRoger\UPRIV
If the file encryption VBS script is activated, CryptoRoger begins encrypting user files. It may encrypt all file extensions associated with:
- Videos.
- Audio files.
- Databases.
- Documents.
- Pictures.
- Virtual Machines.
The ransomware excludes executable files which may damage Windows OS so it can leave it intact. After encryption, the ransomware drops an HTML file on %Desktop% leading to a web link with ransom instructions, which are the following:
Files on your PC have been securely encrypted
Do not worry there is a solution
The cost of decrypting files – 0.5 Bitcoin (~$360)
(but if you will not behave professionally price may increase several times.)

Information for decrypting:
Send me file keys.dat when he needed. The file is required for decrypting.”
Regarding encryption, the encrypted files are no longer accessible and the file extension .crptrgr added to them, for example:
- Filename.pptx.crptrgr
The code for the files used for encryption is considered to be AES-256 – one of the strongest in the world at present times and direct decryption would theoretically take years on a powerful device.
