Description: Cadq Ransomware
Cadq Ransomware is yet another variant belonging to the Djvu family which is released in wild. If you are victim of Cadq Ransomware you cannot access or open your data as it gets locked. The files are held hostage until a ransom fee is paid to the Cadq Ransomware hackers. Once the files are locked, it will be renamed as “.cadq” as extension. Suppose if image file as 1.jpeg will be renamed as 1.jpeg.cadq. Also a ransom note as “_readme.txt” is dropped in all the locked folders containing encrypted data. Ransom note contains all the details related to payment information and states or informs victims that all the files are locked and encrypted via strong cryptography. So it can only be unlocked or decrypted by using decryption tool and there is no other way out there other than paying ransom to hackers. It depends on victims whether they wish to have their data decrypted and how quick they are in paying out the ransom to hackers.

Even if you want to act as quickly as possible, you need to analyze the situation carefully before making any abrupt decisions so you need to remove Cadq Ransomware as soon as you can.
Do Not Pay Ransom to Hackers
Victims can contact hackers and mail them at these given email address and need to pay a lumpsum amount of $980 as ransom fee. If the ransom amount is paid within 72 hours of Cadq Ransomware then victims would get a discount of 50% as it is clearly mentioned in the ransom note. However we do not recommend to pay the ransom to hackers whatsoever. As there is no guarantee that hackers will release decryption tool or unique key for decrypting files. Unfortunately there is no third party decryption tool which is released yet. So it is better to use backup of the data such as documents, files, images and videos to restore data back on computer.
