What is known about CryptorBit virus?

CryptorBit virus is a dangerous ransomware program, which can easily affect Windows OS. It is believed that this ransomware is closely related to Cryptolocker which has already infected thousands of PC users. As soon as it enters the computer, the cyber threat looks for specific files (Microsoft Office files, PDF files and picture type files) to encrypt them. Also, it starts displaying a huge pop-up notification which provides a step-by-step guide explaining the whole decryption process. Typically, it requires visiting a specific payment site and sending a 500 dollar ransom in Bitcoins for its creators. Please, ignore all alerts saying that “your personal files are encrypted” because they are used for the only thing – supporting hackers and increasing their profits. If you are infected, you should waste no time and check your computer with reputable anti-spyware, such as Reimage. This is the only way to remove CryptorBit ransomware from the system.

After being discovered in 2014, a new version of CryptorBit was noticed in July 2016. This time, ransomware requires paying 2 Bitcoins (or $850) in exchange for its decrypter. The amount of money which is required by this virus has almost doubled making, so there is no surprise that security researchers have started calling it “greedy”. Also, it has been discovered that this virus relies on both, AES and RSA encryption algorithms, while to encrypt personal files of the victim. At the moment of writing, it can encrypt 96 file types, but it is believed that this number will increase. According to PandaLabs, this ransomware can be decryptable, but there is no CryptorBit decrypter available on the Internet yet. The only thing that we can recommend is to back up your data and keep a reliable anti-spyware on your computer. Also, make sure that it is up-to-date.
