What is CryptoJoker Ransomware

CryptoJoker is a ransomware family that releases every new file-encryptor each year. Alike other ransomware infections, CryptoJocker pursues data encryption of potentially valuable data (e.g. pictures, videos, music, documents, databases, etc.) to demand money for its complete return. Depending on which version attacked your system, the encrypted files will be appended with one of these following extensions – .encrypter@tuta.io.encrypted, .crjoker, .cryptolocker, .cryptoNar, .cryptolocker, .nocry, .devos, .devoscpu. Those are often accompanied by .fully and .partially suffixes, suposed to mean, that some files are fully or partially encrypted. For instance, a file like 1.pdf may change to 1.pdf.crjoker, 1.pdf.encrypter@tuta.io.encrypted, and so forth. Different versions of CryptoJocker used different formats of presenting ransom instructions. Some display an interactive window, while others create separate text notes. You can check out the versions of all ransom instructions that have been used over the course of CryptoJocker’s existence below:

Although the content is different, the essence remains the same – to pay for decryption software that will recover your data. In order to do this, victims have to contact extortionists by e-mail and send a sum of money in Bitcoin. The price varies depending on versions and individual cases. Some of them may require victims to pay within a certain time frame unless they want the price to be doubled. It is also possible some extortionists will offer an option to decrypt a couple of files for free. Most often this is a trick used to convince victims into paying the ransom eventually. Whatever the case, it is recommended against paying the required ransom. The reason for that lies in the tendency of many cybercriminals to fool their victims and not send any decryption tools even after receiving the demanded money. Luckily, the majority of CryptoJoker versions can be decrypted with third-party programs for free. The name of one is CryptoJokerDecrypter, which was developed by Demonslay335. Download it further in our tutorial and check which file extensions can be decrypted. If you do not see your file extension around the list, then you are likely infected with a newer version of ransomware. In this case, it is worth saving your files and waiting until developers adapt the decryptor for updated extensions. They are working on it and should be able to come up with a solution quite soon. Another option to recover your data is via backup copies. This method will fit in case you are unwilling to wait and want your files recovered right now. Whatever you choose, it is important to delete the ransomware virus from your system to prevent further encryption of data. You will find instructions dedicated to this in our tutorial below.

How CryptoJoker Ransomware infected your computer

CryptoJoker is known to be distributed via malicious PDF files. These files are often spread in e-mail spam letters under the names of legitimate companies (DHL, DPD, FedEx, Finacial organizations, etc.). After seeing a familiar name, users get baited into opening the attached file that is meant to install malware. To increase the chances of opening files, cybercriminals disguise them as something important or urgent that raises the interest of users. Keep in mind that PDF is not the only format used by swindlers to distribute malware. MS Office files like Word or Excel can also be used to proliferate malware the same way. Before closing this part, it is also worth mentioning other distribution channels that can be used to spread various infections. Trojans, fake software updates, infected installers, backdoors, keyloggers, botnets, web injects, malicious ads, and brute force through unprotected RDP configuration are all other channels that you should also beware of. Follow our guide below to perform removal and set up high-level protection against threats like CryptoJoker in the future.

CryptoJoker Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface.
