The key principles of the Chimera virus:

Along with viruses like Locky or CryptXXX, the Chimera virus in a cyber infection which is designed to bring quick profit for its creators. Though the initial preparations and programming of the malicious script may take some time, the efforts are likely to pay back after the virus is released on the web. The ransomware viruses have been proven especially profitable in the last couple of year, so Chimera creators have also decided to give it a go, too, since there are so many successful examples to look up to. Unfortunately for the makers of this virus, this project soon went south regardless of the efforts to keep it going to its fullest potential. Ironically, the virus was hacked itself and its source code was used to develop other cyber infections, including the notorious Mischa and its predecessor Petya ransomware. The same group of hackers also published over 3500 decryption keys completely destroying the Chimera project. These keys allowed the virus researchers to come up with Chimera Decryptor which is now freely accessible online. If you have been infected, worry no more! Go ahead, remove Chimera from your PC and get your files back. Remember to scan your system with Reimage before you run the decryptor!

Chimera ransom note

To elaborate a bit more about the functionality of this virus it is important to note that Chimera ransomware uses .crypt file extension to indicate the encrypted data. The same extension is used by many other ransomware, for instance, one of the initial CryptXXX versions as well. After all of the regular extensions of the predetermined files on the computer are replaced with .crypt, and the victim loses access to all of his/her important data, the virus creates a file featuring a ransom note, explaining the situation. In this note the victims are demanded to pay $617-$1610 USD. Otherwise they are threatened that their personal data will be released publicly. Fortunately, there are no reported cases of such data leaks, simply because the virus was quickly decontaminated. In case some version of the infection still managed to reach your computer, keep calm and proceed to the Chimera removal.

Virus distribution and infiltration techniques:

Ransomware viruses differ from other, less serious viruses and potentially unwanted programs because they often pretend to be something other than they really are. This deceptive approach allows them to enter victim’s computers undetected and start ravaging through them immediately. But what are these methods of infiltration exactly? Here are several most common ways Chimera takes over computers:

  • Email. The most common way ransomware viruses spread is email attachments. The malicious virus script disguises itself as a Word or Javascript document and is distributed via spam emails. When the user unknowingly downloads such a file, the ransomware activates itself, and you know the rest of the story yourself.
  • Corrupted ads. Compared to ransomware, adware viruses look quite innocent. However, they can be evil apprentices of the ransomware infection too. These ad-based programs stuff the browser with an extensive amount of ads and links which are often unverified, so naturally, not always safe. By clicking on a corrupted add, you may download a ransomware virus on your device directly or be rerouted to a site which involves in ransomware distribution and gets tricked into installing an infected application as well.
  • Software downloads. As we have already mentioned, Chimera ransomware can secretly crawl into your computer after your download some infected application. Such applications usually carry a Trojan virus which later helps the ransomware to get installed on the computer, bypassing all the systems of defence.

Things to remember before taking up Chimera removal:

If your device got infected with Chimera ransomware, quick reaction is the key. The first thing you should do after noticing first signs of an infection is to disconnect your computer from the network. The quicker you do that, the more files you will likely save from being locked since the virus Command/Control center needs a constant connection to perform the encryption. Then, you can proceed to the Chimera removal. This process should be automatic, though you might need to adjust some things manually as well. Be careful and use only the reliable antivirus software to deal with the virus. Take note: to keep your data safe from similar attacks in the future, make backup copies of your files and keep them safely stored on external storage drives.
