What is Cdqw Virus/Ransomware and How to Handle It

Cdqw ransomware, part of the STOP (Djvu) family, is a malicious software that sneaks into computers, locks files, and demands payment for their release. It’s sneaky; it can get into your computer when you download programs from sketchy sites, use hacked games, or install fake Windows or Office tools.

How It Works

Once Cdqw sneaks into your computer, its first step is to establish a base within the Windows system directory. Here, it makes a copy of itself, ensuring that it’s deeply rooted and harder to remove.

Next, it tries to reach out to its home server on the internet. This connection attempt is its way of getting a unique encryption key called the ‘online key’. If, for some reason (like no internet or a blockage), it can’t connect to its server, it’s prepared with a backup plan. It uses a stored ‘offline key’ instead, which is a sort of one-size-fits-all key.

With this key in hand, Cdqw gets to its main mission: locking up your files. It goes through your documents, photos, videos, and more, encrypting them. This means it scrambles the data so you can’t access them. As a sign of its work, it renames each file by adding “.Cdqw” at the end. For instance, ‘song.mp3’ becomes ‘song.mp3.Cdqw’.

However, Cdqw isn’t completely without mercy. It skips certain files that your system needs to run, such as those ending in .dll, .lnk, .bat, and some named “_readme.txt”. This way, your computer still works, but your personal and important files are held hostage.

To let you know what’s happened and what it wants, Cdqw drops its ransom note. In any folder that has these newly renamed files, you’ll find a note titled “_readme.txt”. This isn’t a helpful read-me; it’s a message from the attackers, telling you they have your files and want money to release them. 📜💰

Is There Hope?

Yes! If your files got locked with the offline key, tools like Emsisoft’s Cdqw File Decrypt Tool can help. But if it used the online key, things are trickier. Paying the attackers is risky; they might not unlock your files even after getting the money.

Cdqw’s ransom note reads as follows:

To decrypt files encrypted by Cdqw File Decrypt Tool, it is important to know which key was used during encryption. You can find out the type of key used through two methods. Both methods are effective, but the second method is considered to be more accurate and therefore recommended.

Identifying the Type of Key Using the ‘_readme.txt’ File

• Open the ‘_readme.txt’ file, which is the ransom demand message created by the Cdqw ransomware.
• Scroll down to the end of the file.
• Look for a line of text that says ‘Your personal ID’.
• Below this line, you should see a string of characters. This is your personal ID, which is unique to your computer and is used to generate the decryption key.

Identifying the Type of Key Using the ‘_readme.txt’ File

• Open the C drive on your computer.
• Open the ‘SystemID’ directory.
• Look for the ‘PersonalID.txt’ file and open it./li>
• This file contains a list of ‘Personal IDs’ that match the keys that the ransomware used to encrypt files./li>

The ‘Personal ID’ is not the actual key that was used to encrypt files, but rather an identifier that corresponds to it. If the ID ends with ‘t1’, the files were encrypted with an offline key, whereas if it does not, the Cdqw virus used an online key. If you are unable to determine which key was used, you can request assistance by submitting a query here or in the comments section.

Cdqw File Decrypt Tool : “No key for New Variant online ID”
