The Wana Decrypt0r 3.0 Ransomware is a Trojan that performs attacks similar to the WannaCryptor Ransomware, which can encrypt your files to lock them and display messages selling the unlocking method. However, the Wana Decrypt0r 3.0 Ransomware doesn't encrypt any content, making paying a ransom needless entirely. Protect your PC proactively or remove the Wana Decrypt0r 3.0 Ransomware infections after the fact with appropriate anti-malware software and strategies.

Trojans Misusing Names to Get What They Want

With the anti-malware industry placing more attention on the renewed activities of the WannaCryptor Ransomware family (also known as Wcry or WannaCry), victims seeing pop-ups resembling an attack from the same Trojan may lead to obvious, but not always correct, conclusions. New imitators of this threat also are in sight, such as the Wana Decrypt0r 3.0 Ransomware, which doesn't even include any file-encrypting features, so far. However, its close resemblance to other threats with more significant capacity for damaging data could lead to the fruitless payment of ransoms.

Contradicting both its misappropriated brand identity and some title lines on its warnings, the Wana Decrypt0r 3.0 Ransomware targets Chinese users instead of English speakers. While the Wana Decrypt0r 3.0 Ransomware doesn't encode or, in other respects, damage your files, it does display pop-up alerts meant to imitate the Wcry family precisely. The HTML window it loads provides various features for enhancing the ransoming process automatically by pretending to be a symptom of a non-consensual, data-encrypting attack.

Some especially significant elements of that window include a timer that threatens to increase the price of the ransom when it reaches zero, a copy-friendly Bitcoin wallet address and additional encryption warnings in Chinese text. The Wana Decrypt0r 3.0 Ransomware's threat actors are setting their current ransom demands to a surprisingly high 600 USD equivalent in Bitcoins, although, without data encoding to back up the pop-up, the justification for paying such a fee remains slim.

Genuine Solutions to Disingenuous Pop-Up Attacks

The Wana Decrypt0r 3.0 Ransomware's primary security risks come from its potential for disabling other applications automatically or using its pop-up to lock you out of using the Windows interface. While victims should see no real consequences from ignoring the Wana Decrypt0r 3.0 Ransomware's timer, other threats with more internal features are capable of launching similar attacks, triggering actual data loss that's difficult or impossible to remedy. Keeping backups can help protect you from the real members of the WannaCry family and any variants of the Wana Decrypt0r 3.0 Ransomware benefiting from file-encrypting updates.

The Wana Decrypt0r 3.0 Ransomware is a threatening software meant to force you into paying money under duress and is a threat to your PC's safety, even if it doesn't block or delete any files. Its model for circulation and installation has yet to see confirmation, although malware experts often witness Trojans of the same type distributing themselves in e-mail attachments. Anti-malware products with updated databases have the best chances of removing the Wana Decrypt0r 3.0 Ransomware before it loads any attacks against your system.

The high ransoming fees of the Wana Decrypt0r 3.0 Ransomware are implicative of corporations and other business entities being prime targets, but the lack of real encryption points a finger closer towards personal systems. No matter who's under attack, it always pays to verify what's happening 'behind' the scenes instead of taking the word of a Trojan.
