Craw – General Info

Craw is a malicious software application functioning as common ransomware. Michael Gillespie, the widely known virus researcher, very first found this new name in the DJVU ransomware family.

Craw was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively accomplished, the users are not able to get access to them. Craw ransomware adds its own “.craw” to all the encrypted files. For example, the file “price_list.xls”, once modified by Craw, will be entitled as “price_list.xls.craw”. As soon as the encryption is achieved, Craw puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by _readme.txt requesting the random os really similar to the alerts provided by other ransomware dangers belonging to the DJVU family. The warning essentially shows that the data has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The technique to secure the files used by Craw is not totally looked into. However, there is no doubt that each computer owner might be released a special decryption key, which is definitely special. It is extremely hard to recuperate the data without the proper type in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Craw ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have released the Craw infection into the web. In order to get the key and restore the crucial information, the users are informed to connect with the frauds via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also states that the people should get in touch with the Craw authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so individuals will acquire a 50% discount, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no warranty that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom typically does not lead to an effective recovery. So, the users might merely lose their money for nothing.

There are no applications that could split the Craw virus or restore the information at no cost. For that reason, the only appropriate decision is to bring back the data from possible backups (if readily available).
