CRPTD Ransomware

CRPTD Ransomware Description

The CRPTD Ransomware is a crypto locker threat that so far has not been attributed to be part of any existing ransomware family. That, however, doesn't mean that CRPTD deviates from what is considered a typical ransomware behavior. After infiltrating the targeted compute, it initiates its encryption process that will render nearly all of the files stored on the system to become inaccessible and unusable. Victims will find themselves 'locked out' of their own fi suddenly. The name of every encrypted file will be modified to include '.CRPTD' as a new extension. The ransom note with instructions from the hackers will be dropped in the form of .hta files named 'Recover files.hta.'

Once all your important data is encrypted, the CRPTD ransomware creates a ransom note called Recover Files.hta. The ransom note explains the situation to victims and encourages them to pay a ransom note to decrypt their files. The file says that all of the data has been encrypted, and the only way to decrypt it is with special tools created by the cybercriminals who also created CRPTD ransomware. Victims have to contact the attackers through email to receive further instructions. Another email address is provided for people to use if they don’t get a response within three hours.

The end of the ransom note warns users against attempting to decrypt files themselves or rename the files. Doing so could allegedly cause permanent data loss. The ransom note also says that other decryption tools aren’t compatible with their virus. How much one has to pay for the ransom isn’t stated in the note. In general, the ransom demand increases the longer a victim takes to respond.

No matter the size of the ransom, however, experts always warn against paying. It would be best if you never trusted cybercriminals to live up to their end of the deal. They have a reputation for ignoring people once they get their money, meaning you lose all your money as well as your data.

Affected users are told to send an email containing the unique ID number assigned to their computers, as well as attaching three encrypted files. The files have to be either images, text or documents. The provided email addresses are and

The text on the note left by CRPTD is:

How to deal with CRPTD Ransomware

The worst thing you can do if your computer gets infected is to pay the ransom. There is only one way to recover your files, and that’s to use a data backup. Make sure that you remove the virus before restoring files to prevent the backup from being encrypted too. This method is the only way to get your files back without paying the hackers.

Most ransomware detection and removal tools can remove this virus. The hard part will be restoring your files as not everyone keeps backups of their data. If you don’t already have a cloud or external backup of your important files, then it’s time you looked into getting one.

How Did CRPTD Get on my Computer?

Hackers have several ways to get their digital threats on your computer. The most common infection method for ransomware, such as CRPTD, is email spam campaigns. These campaigns see attackers send thousands of junk emails that contain malicious links or file attachments. The emails are written to trick readers into believing they come from official sources and have important information. When the reader opens the link or the file attachment, their computer is infected with the malware.

Another standard infection method is to use untrustworthy download channels. These third-party sites promote rogue applications as legitimate software. Fake software updates are another common infection method. It is important to keep software and apps updated, but you should always do so with official channels. These fake updates install ransomware and other viruses rather than the promised software update.
