How to remove Ouroboros Ransomware and decrypt .odveta, .harma, .lazarus or .bitdefender files

0
Ouroboros Ransomware (a.k.a. Zeropadypt Ransomware) is an extremely dangerous virus, that forcibly encrypts and blocks off the access to personal data. By doing so, Ransomware developers prompt users to pay a ransom (around 1000$) for getting a unique decrypting key. When infiltrating the device, it immediately starts rushing through files like images, videos, music, text documents and other valuable data that can be stored on your computer and encrypts it by using the AES-256 encryption algorithm. After that, ransomware assigns a unique .odveta extension to each file, therefore, making it impossible to open. For example, if sample.mp4 gets encrypted it will change the file name to sample.mp4.odveta. There are many other versions and variation of Ouroboros Ransomware, that change file extensions to .bitdefender, .harma, .rx99, .Lazarus, .Lazarus+, .James, .lol, .hiddenhelp, .angus, .limbo, or .KRONOS. Some of the recent extensions like .bitdefender, were created as mockery, because BitDefender released decryption tool, that, unfortunately, cannot decode latest Ouroboros Ransomware species.

STOP Ransomware is a cynical virus that knocks out the soil and leaves users at a loss because it affects the most intimate type of information - personal photos, videos, e-mails, as well as documents, archives, and other valuable data. Ransomware is a type of threat that not only encrypts those files but demands a buyout. STOP Ransomware is officially the most wide-spread and dangerous virus among the file-encrypting type of malware. There have been more than 200 versions of it and latest struck with .btos, .npsg, .reha and .topi extensions. Such suffixes are added by STOP Ransomware to files it encodes with its powerful AES-256 encryption algorithm. In 99% of cases, its algorithms are unbreakable, however, with instructions and utilities covered in this article you get this 1% chance of recovery.

Phobos Ransomware is a virus, that encrypts user files using AES encryption algorithm and demands ~$3000 for decryption. Ransomware adds .phobos, .mamba, .phoenix, .actin, .actor, .blend, .adage .acton, .com, .adame, .acute, .karlos or .Frendi extensions to encoded files and makes them inaccessible. In order to confuse users and researchers Phobos Ransomware uses file-modification patterns and ransom notes similar to very wide-spread Dharma Ransomware. Especially after design change in January 2019, when they started to look like identically. However, there are certain differences in file-markers and appearance. After contacting the developers via one of the provided e-mails, they demand $3000 in BitCoins for decryption to be paid in 6 hours. Otherwise, the cost of decryption will increase up to $5000. At the moment automated decryptors for Phobos Ransomware do not exist. There is no proof, that malefactors send decryptors to the victims, that is why we do not recommend paying the ransom. Instead, try using instructions on this page to recover encrypted files. File-recovery software can restore some files from your hard-drive.

How to remove STOP Ransomware and decrypt .kodc, .nosu, .piny or .redl files

If your files became unavailable, unreadable and got .kodc, .nosu, .piny or .redl extensions it means your computer is infected with a variation of STOP Ransomware (or as it is, sometimes, called DjVu Ransomware). It is a malicious program that belongs to the group of ransomware viruses. This virus can infect almost all modern versions of the operating systems of the Windows family, including Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. The malware uses a hybrid encryption mode and a long RSA key, which virtually eliminates the possibility of selecting a key for self-decrypting files. Like other similar viruses, the goal of STOP Ransomware is to force users to buy the program and key needed to decrypt files that have been encrypted. The version, that is under research today is almost identical to the previous ones, except new e-mails used for contacting malefactors and new extensions added.

Dharma-Wiki Ransomware is a file-encrypting type of malware designed to deprive the money and nerves of its victims. It belongs to the notorious Dharma/Crysis Ransomware family.
