A new type of ransomware infection, carrying the name ‘DESKRYPTEDN81’ along with it has been reported to be encrypting victims’ files with the purpose of extorting them for funds. This type of threat corresponds to the ransomware attacks, detected as Ransom:Win32/Troldesh. This kind of ransomware has several variants and is seen to encrypt the files with the .Crypt extension in the affected computer. Once encrypted the files may not be able ever to be decrypted unless a corresponding decryption key is used. This decryption key is the sole purpose of the ransom note that this threat leaves after encrypting. This summary includes instructions on how to restore your files by paying the cyber criminals. Security experts recommend not to trust cyber criminals because it is no guarantee whether the files will be decrypted after making a payment.
How Can You Get Infected With DESKRYPTEDN81?
Infections with this ransomware trojan may vary. Most of them are conducted via spam messages or spoofed email addresses. Email attacks feature an attachment in the messages that usually has the initial exploit that begins the infection. Another method of infection is by dropping an executable file on the computer. This can happen if someone else has access to the same computer you are using, but can also happen if you download a file from the cloud. Another mean of infection is the so-called drive-by downloads, caused by redirects. Drive-by downloads are very dangerous since they directly infect the computer with malicious code. And if the user has an adware program or a browser hijacker that causes redirects to such pages, they may get infected.
How Does DESKRYPTEDN81 Work?
Once installed on the computer, this particular ransomware may:
1-Scan the computer for various file formats of relevance and importance to the user.
2-Encrypt the files with strong encryption, almost impossible to decrypt, leaving a .crypt or a similar unknown format after their names. (RSA, for example)
3-The Trojan leaves a ransom note with instructions on how to establish an anonymous connection with the cyber-criminals along with a deadline. After this period expires, the decryption keys may either be lost forever, or the fee might double.
This particular ransomware is reported by affected users to leave a ransom note which has a law-enforcement agency logo, such as the FBI, for example.
