Ransomware

DearCry Ransomware is a dangerous virus, which targets the encryption of personal data. Such malware makes everything sure that there is no way to decrypt the locked files. Knowing that, cybercriminals offer their own solution - to buy the decryption key stored on their servers. Because most users can find no way out of the trap, they agree on paying the ransom to recover the data. Unfortunately, this is a serious risk proven by multiple victims who did not receive the promised decryption. This is why it is better to delete DearCry Ransomware and reclaim your files via backup or data-recovery tools. If you are the one having files changed with the .crypt extension, which was then accompanied by the ransom note creation (readme.txt), chances are you are infected with DearCry Ransomware.

Developed on Node.js, JoJoCrypter is a malicious program that functions as a data-encryptor. A thorough investigation conducted recently shows there is a .jojocrypt extension assigned to each of the files. To illustrate, a non-encrypted 1.mp4 will turn into 1.mp4.jojocrypt as a result of infection. Along with this, it is also known that JojoCrypter uses RSA-2048 and AES-192 algorithms to cipher innocent files. It also creates a short ransom note how to recover your files.txt with following content. Unfortunately, the decryption with third-party tools appears to be an impossible task. The encryption chains are too strong and flawless to crack. This is why the only option (apart from paying the ransom) is to recover your files using backup or data-recovery tools. Otherwise, you will be forced to pay for the keys proposed by cybercriminals, which is mentioned in the ransom note dropped on your PC after encryption. Swindlers are not using too many words for describing what happened, instead, they attach their e-mail address to be contacted for further instructions.

Parasite is one of the newest ransomware samples detected by cyber experts in recent days. Alike other malware of this type, Parasite encrypts personal data and demands money for the decryption. However, it was found that Parasite has a significant flaw - it encrypts data with the wrong cipher and overwrites data with 256 bytes. This means that all data encrypted by Parasite loses its value completely, simply because it gets replaced with empty space. For example, a word file, which weighs megabytes of data will decrease and start weighing mere 256 bytes. Such a bug instantly shows that Parasite is not able to decrypt your files, simply because they become damaged. Of course, they claim to decrypt them in HOW_CAN_GET_FILES_BACK.txt ransom note (alternatively @READ_ME_FILE_ENCRYPTED@.html or info.hta), which is created after encryption, but it does not make any sense due to the above-mentioned.

Perfection is a ransomware-infection that involves RSA and AES algorithms to encrypt personal data. The purpose of such attacks is about capitalizing on desperate victims willing to restore their files. As a result, developers behind Perfection offer to pay for the decryption tool that will help you regain access to data. Before that, however, Perfection Ransomware appends the .perfection extension to each of the files. For example, 1.mp4 will change to 1.mp4.perfection and so on. Then, once this process is done, extortionists create a number of identical browser files and place them into folders with encrypted data. The ransom note created by Perfection is known as Recovery_Instructions.html.

Using a set of cryptographic algorithms, Assist Ransomware encrypts personal data and claims money for its decryption. This practice is highly-popular around ransomware infections as they make everything possible to leave no choice to desperate victims. Because of powerful ciphers applied by Assist, manual decryption becomes quite an arduous task. This is why cybercriminals offer to contact them via the team-assist002@pm.me e-mail address and receive further instructions. This information is listed inside of the note (ASSIST-README.txt) created after your data is locked completely. Not to mention that this version of ransomware encrypts files using the .assist extension. To illustrate, a file like 1.mp4 will get a new look of 1.mp4.assist after the encryption is done. As mentioned, the only possible method to get 100% decryption is with the help of ransomware developers, however, this is not the best option since they can fool you and do not give any software for restoring the data. We strongly insist on deleting Assist Ransomware from your computer to prevent further encryption, especially if you do not regret the lost data that much.

According to recent forum reports, users are dealing with a new ransomware infection known as Bonsoir. This virus targets local networks (NAS, QNAP, Samba/SMB, Synology) encrypting the stored data with AES-CFB algorithms. The decryption of files is thereby offered inside of a text file called HOW-RECOVER-MY-FILES.txt. To elaborate on data encryption, we should mention that Bonsoir applies a one-word extension to each piece of data - .bonsoir. For example, if there was a file named 1.mp4 in your storage, it will change to 1.mp4.bonsoir as a result of infection. Developers of the virus claim their instructions to be the only solution towards restoring your files. One of the victims actually emptied his pockets and bought the decryption key imposed by extortionists. He, therefore, managed to recover his files with the provided key. Unfortunately, this method does not fit everybody because of the high amounts required by cybercriminals and the risk to be fooled by them. This is why our advice is to delete Bonsoir QNAP NAS Ransomware and try using legitimate utilities to access your data.

Cuba Ransomware is a malicious program, which uses a set of cryptographic algorithms to encrypt personal data. The virus has been seen in different versions with different styles of encryption. They might differ by ransom instructions, but usually, all of them apply the same .cuba extension and FIDEL.CA file marker in the header. For example, an infected file like 1.mp4 will transform and start looking like this 1.mp4.cuba or similar. Then, once the encryption is up, Cuba drops a text file stating how to decrypt your data. Many victims have received various instruction samples (!!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT). In most of the cases, all of them tell victims to contact the attached e-mail with their personal ID number. After this, people will get the necessary steps to run the payment and retrieve the decryption tools promised by the developers. Unfortunately, statistics upon successful decryption are pretty poor. This is because there are potent ciphers applied to the files, which makes it hard to decrypt them.

Cring is categorized as a ransomware-type virus that encrypts personal data of various sorts (images, videos, documents, etc.) To make the encryption successful, Cring applies special cryptographic algorithms, which establish strong cipher protection. All of this is accompanied by the assignment of the ".cring" extension, which is added to the end of each file. As an example, the original piece like 1.mp4 will be changed to 1.mp4.cring and reset its icon. Whilst this process is underway, the virus prepares to drop a text file (!!!!deReadMe!!!.txt) containing ransom instructions. Inside of a document, extortionists are straightforward saying that your files are impossible to unlock on your own. The only solution is to contact developers and pay a fee of 2 bitcoins. Unfortunately, because the infection is very new to the ransomware world, cyber experts have not found a way to decrypt it for free just yet.
