    What is Cdwe ransomware?

    Cdwe virus is a ransomware-type that belongs to a STOP/Djvu family. Like any other ransomware, it is aimed at your money. This malware encrypts your files with a strong cipher and then asks you to pay the ransom (~$1000) for file decryption. To prevent the file decryption by the alternative ways, Cdwe virus makes some changes to your system.

    These changes are related to the security settings. First, malware stops your Microsoft Defender and blocks the third-party security tool if you have one. Then, it changes the Group Policies to block the launch of the installation files of antivirus programs. The final step is blocking access to websites that contain information about file decryption and malware removal. These changes may affect PC usage in the future, so it is better to remove them as soon as possible.

    A few words about the spreading ways of Cdwe ransomware: this virus did not appear out of nowhere - you have likely installed it together with a program of some sort. “Free” programs, which must originally be paid, are created by unknown users. During the hacking process, they are free to add whatever to the executable code of their product - spyware, coin miners, ransomware, or stealer. It is better to avoid such risks, especially when you cannot punish those persons through the police, for example.

    Encryption process

    The Cdwe ransomware uses the Salsa20 encryption algorithm. That is not the strongest method, but it still provides an overwhelming amount of possible decryption keys. To brute force the 78-digit number of keys, you need 3.5 unvigintillion years (1*10^65), even if you use the most powerful regular PC. Quantum computers can show a bit better results, but it is still too slow to get your files back while you are alive.

    The exact algorithm of encryption is next: malware scans each folder for the files it is able to encrypt. Then, when it finds the target, it makes a copy of your file, removes the original one, encrypts the copy and leaves it instead of the removed original. Such a procedure is done to prevent the situation when you have already opened the file, so ransomware is not able to read it because of the Windows restrictions. To each encrypted copy, the virus adds the specific extension - ".cdwe". Then, ransomware creates a _readme.txt file in the folder where the encrypted file is located, and goes to the next folder.

    .CDWE Files

    Such an encryption method can be exploited for file recovery. Since the original file is deleted, you may try to recover it using the file recovery tools. The less time is passed - the bigger the chance to get your files back, so hurry up!

    Another specific moment that can help you to use the files even after the encryption is the fact that Cdwe ransomware encrypts only the first 150KB of each file. Hence, you can try to run a big file, such as video or music, without the encryption. Similar feature also works with other ransomware families - Dharma, Conti and Makop encrypt the same 150KB.

    Ransom note: _readme.txt

    Ransom note is the same for the whole ransomware family. In fact, it is one of the main signs of to which family the certain ransomware belongs. Here is the typical note for STOP/Djvu family:
