CryptOstonE ransomware has been spotted in the wild. It is a threat reported to corrupt computer systems and encrypt personal files stored on the drives. This ransomware renames files with the suffix .encrypted. The specific pattern noticed for this ransomware is that it places the malicious suffix between the file name and the file type extension. For example, the file image.jpg will appear like image.encrypted.jpg once it gets encrypted by CryptOstonE virus. At the end of the attack, the ransomware display a file that extorts a ransom fee for .encrypted files recovery. Beware that a ransom fee transferred to cybercriminals does not guarantee anything. There are quite a lot of users that pay the ransom and lose both their files and money.

CryptOstonE Virus

CryptOstonE virus attack campaigns can target online users worldwide. Popular techniques used for the spread of malicious software including malspam, freeware installers, and corrupted websites may be utilized for the campaigns.

Malspam is believed to be preferred by hackers because it allows them to push massive spam email campaigns against lots of people. Emails included in such campaigns are designed in a way that tries to trick people to download malicious software on their machines. The malicious software may be presented as an important document attachment, a clickable link/button, or another interactive form.

When CryptOstonE payload file runs on a system, it initiates a long sequence of malicious operations that corrupt system security. Unfortunately, the attack could remain unnoticed till the end due to the fact that C ransomware may operate in the background of all other running apps.

All modifications applied by the ransomware leave the operating system vulnerable to further malware attacks. They interrupt its proper performance as well. After the data corruption occurs, personal files remain inaccessible and renamed with the extension .encrypted which stands between their original name and file extension.

At last, CryptOstonE ransomware creates a file that contains its ransom message. The file contains a specially crafted message that attempts to extort a ransom fee for a tool that is possibly capable of decrypting .encrypted files. Here you can see a copy of the text presented by this pop-up message:

Your files has been safely encrypted

The only way you can recover your files is to buy a decryption key
The payment method is: Bitcoins. After you buy the required amount send the payment to and email proof of payment to . Also include your computers System Name (You can find this inside of System Information). The price is: $2000 = 0.00350278 Bitcoins

Be advised to refrain from paying hackers the ransom of $2000 in BitCoin. This action provides no guarantee that you will receive a decryptor which can decrypt .encrypted files. The code of the threat may be full of bugs that prevent the decryption tool from working smoothly. Hence, we recommend that you remove CryptOstonE ransomware and try to recover .encrypted files with the help of alternative methods.
