Remove LETO Ransomware Virus (2022 Guide)

LETO ransomware virus seeks to take your files hostage for a ransom

LETO ransomware is the latest version of the STOP/DJVU virus (v0172). This crypto-malware variant seeks to infect computers or networks and encrypt all files using AES+RSA cryptography methods. During the encryption, ransomware marks files with .leto file extension and creates a ransom note called _readme.txt in every folder containing corrupted data. Cyber attackers demand a $490-$980 ransom in Bitcoins and suggest contacting them via gorentos@bitmessage.ch or amundas@firemail.cc.

Once installed, LETO virus executes series of commands via command prompt. This way, it disables the firewall, deletes Volume Shadow Copies and disables important Windows services for a smooth virus operation. It also installs Azorult-password-stealing Trojan on the infected machine. Then it starts encoding files to make them inaccessible for the victim.

At this point, you need to know that LETO ransomware virus can use either online or offline key to encrypt your data. If it uses the offline key, it inserts a personal ID ending with t1 in the ransom note (_readme.txt file). This means that you have chances to decrypt some of your files, so be patient until the experts create a Leto decryption tool. If your files were encrypted with the online key, your personal ID won’t end with t1, and at this moment there are no ways to decrypt your data.

The ransom note contains a threatening message

The ransom note created by the virus describes that important documents, databases, photos and other files were encrypted. The attackers have a private key which is required to decrypt .leto file extension files. However, the cyber attackers want the victim to pay for it, or, in other words, they try to extort the victim for a ransom by keeping one’s files hostage. 

The attackers demand a hefty sum of money, which depends on how fast the victim reaches out to the criminals via provided emails. In case the victim pays up within 72 hours, the ransom price is $490 (50% discount). Otherwise, the price is $980. The ransom must be paid in Bitcoin for the sake of the attackers’ anonymity.

Ransomware developers’ message in the _readme.txt note

This ransomware variant is essentially the same as previously released RECO, BORA, NOOS, BOOT OR KUUB variants. Based on the extension that it adds to encrypted files, this STOP/DJVU ransomware variant was called Leto file virus.

Keep in mind that it is not advisable to pay the cybercriminals – they seek to convince you to transfer money to them, but that doesn’t necessarily mean you will get the decryption software. Remember that cybercriminals are scammers, and they don’t really care about your welfare. Therefore, if you have been attacked by this virus, think about the data backups you have and remove Leto ransomware using a strong antivirus solution. 

After removing the virus using the instructions provided at the end of this article, change all your passwords, especially those saved in your browser to prevent private data or financial loss due to Azorult Trojan activity.

Ransomware attack methods

To prevent future ransomware attacks, victims need to learn what methods malware developers use to spread ransomware. First of all, ransomware viruses typically need very little user interaction in order to execute.

Once run, it can bypass certain security solutions, so one of the main ransomware prevention methods is to AVOID clicking on something that contains malware. Leto (Stop/DJVU) malware developers are known to include the malicious executable in:

• Pirated software;
• Windows and Office activators (KMSPico and others);
• Adware bundles;
• Software cracks;
• Emails containing malicious attachments or links.

No matter how attentive you are while browsing online, develop a habit of creating regular data backups as it is normally the ONLY way to recover your files after a ransomware attack.

Best methods to remove LETO ransomware virus

The best way to remove LETO ransomware virus is to start your computer in a safe environment and eliminate existing threats with up-to-date antivirus software. You can use the antivirus you have or choose from free or paid options. Keep in mind that most security programs remove viruses for free, but if you want real-time protection, you need to get the antivirus subscription.

After LETO virus removal, concentrate on data recovery. If you didn’t have any backups, try to restore as many files as possible from sources such as Facebook messages, emails, USBs, Google Drive, and others. Finally, as mentioned earlier, if your personal ID starts with t1, you have a chance to recover some files in the future. 

At the moment, there are no ways to decrypt files no matter if your files were encrypted with online or offline key. Please be patient and wait. In the meantime, backup encoded data. It is unknown how long it might take to extract the offline key for data recovery due to the complexity of the ransomware.
