Leto ransomware is a hazardous computer virus that use file-encrypting scheme. It forbids victim from accessing personal and important files. Cyber attackers declared that paying a ransom is the only solution to decode all infected files.
Leto ransomware is a crypto-virus that belongs to STOP/DJVU clan. This popular computer infection continues releasing a different variant like .coot, .nakw, .reco and so on. On this particular threat, it uses .leto extension to all encrypted files.
Similar to its other versions, Leto ransomware encrypts the file using a strong encryption algorithm. Once the encoding process is completed, victims cannot access their files anymore. It encrypts databases, documents, images, videos, and other valuable data.
Now, this is the catch, before a victim can open or use those files again, the amount required by cyber crook must be settled first. This sum is supposedly payment for decrypt tool and unique key. The Price of a private key and decrypt software is $980, it also offers a 50% discount if the victim contact malware author within 72 hours. It provides email address gorentos @ bitmessage.ch and amundas @ firemail.cc to get in touch with cyber attacker.
Leto virus drops a ransom note and emphasizes that without paying, files cannot be restored. It asserts that the only way to recover files is to purchase for the decryption tool. Please be mindful that paying the ransom is not the solution to this issue. Even if you pay the demanded amount, there is no guarantee that they will send you the private key and decrypt software.
The mere objective of Leto virus is to extract money from its victim. Thus, once they collect the money, they care no more to your encrypted files. Never attempt to deal with online attackers. The best option you can do now to bring back files is through your backup. However, if you did not store files regularly, it is a great regret. It is much better and safer to backup data at all times. Consider storing your files via external drive like USB or hard disk with optimum capacity.
To prevent Leto virus and other similar threats online, be more vigilant especially when installing free programs. The most common way to deliver Leto is through the bundling method. It usually hides as an extra application to free downloads. Thus, never install freeware or shareware in Default mode. Always opt for Advanced (Custom) settings so you can remove tick mark on applications that seem suspicious or unknown.
