Ransomware
If your files have been encrypted, we accept the challenge of analyzing your case.

Ransomware Crypton

The CryptOn ransomware was discovered around 2017. Since then, it has had varying nomenclatures, such as Cry9, CRY36, Cry128, Nemesis or X3M. CryptOn is part of the CryptoLocker ransomware family.

CryptOn steals and encrypts the victim’s data. In this way the group applies double extortion, which consists of threatening the victim with the publication of the data if the ransom is not paid in the given time.

Access to the victim’s environment can take place manually via RDP (Remote Desktop Protocol), allowing remote access to a target machine, as well as through e-mail campaigns that carry malicious attachments or links.

CryptOn ransomware analyzes mapped network drives and the hosts it is connected to for access to folders and documents during execution. The files are then renamed and encrypted using the RSA-2048 and AES-256 algorithms.

CryptOn uses a simple but long pattern to rename the infected files. All infected files are given an extension consisting of the original file name, the victim ID and the email address to send the proof of payment for the ransom, with this structure ”[original_file_name] .id- [victim ID] _steaveiwalker@india.com_”.

After encryption, the CryptOn ransomware generates a ransom note file called ”’HOWTODECRYPTFILES.html”.

From that moment the victim is faced with the need to make an important choice. Pay the ransom and fund future cybercriminal attacks or find a competent company that can recover his data.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

Yes, it is possible. You can restart the computer in safe mode which will limit the ransomware’s action as system resources will be locked. You can also disconnect the computer from the Internet which can interrupt the hackers’ connection to your system, it is worth remembering that there is ransomware that works even without being connected to the Internet. You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and even the hackers could not restore the files, even with the decryption key. In these cases only a data recovery company, such as Digital Recovery, can recover the files.
