Cerber Ransomware fixes encryption flaw; makes Decryption Tool ineffective

We recently talked about the Cerber Ransomware Decryption Tool from Check Point and how it would help victims to decrypt files encrypted by the ransomware. However, the decrypter was useful only for a short period of time, only to those who decrypted files in the initial hours of its release.


Cerber Ransomware Decryption Tool rendered ineffective

The decrypter’s life has been cut short by the Cerber authors soon after a report highlighting the tool capabilities was released by the company.

The Cerber Ransomware owners have managed to fix the flaw in the Ransomware encryption that Check Point researchers exploited to come up with a Decryption tool.  Rendering decryption tool as useless, Cerber authors have beefed up their encryption leakages.

Here is what Check Point had to say after it was found that Cerber Ransomware encryption flaws have been fixed,

“Unfortunately, following our report, the authors of Cerber managed to fix the flaw in their encryption process which enabled us to decrypt files encrypted by Cerber. During the time the decryptor was functional, hundreds of users managed to decrypt their files using our decryptor. We will continue to search for new ways to decrypt files encrypted by Cerber and other ransomware, and return them to their rightful owners”.

Following the fix, Check Point has removed the Cerber Ransomware decrypter tool from its website. On the other hand, such an immediate fix by Cerber authors shows how actively they are monitoring the progress of their Ransomware which has earned them great commercial rewards in a short time. Perhaps it’s time for the Internet users to be extra cautious from the phishing emails and other online threats.
