What is .[cyberunion@tuta.io].CU?

The one of the recently detected threats is called CU ransomware. This virus belongs to the Dharma file-encryption ransomware family. In the most cases, CU ransomware spreads by the means of various fake installators, that are shared by numerous file sharing websites and torrent trackers. Sometimes the criminals even create special websites, that deceive users into downloading and installing of such a file as if it’s something necessary. Moreover, hackers often attack remote access ports and infect computers remotely and unnoticed. The same mechanism is used in case of remote access software, that can be also installed unnoticed and distributed with a bundle. This soft gives to criminals nearly a full access to computers and gives them an opportunity to infect them remotely. When CU ransomware is in the system, it makes some changes in the Registry and injects into a system process. When it’s done, it begins to search for files, suitable to be encrypted. In the most cases, these files are all formats of media files and documents, as these files generally are the most important ones. Encrypted files get the new “.id-*id*.[cyberunion@tuta.io].CU” extensions. Then the virus creates a special process, the window of which contains the ransom note. Unfortunately, the surest way to decrypt data is to get the decryptor from criminals, but, as the rule, they don’t answer to their victims after being paid. Moreover, it’s nothing for them to make the situation much worse. That’s why we strongly recommend you to stay away from dealing with them and for this purpose we’ve prepared the detailed guide on how to remove CU ransomware and decrypt .[cyberunion@tuta.io].CU files!
