Grod ransomware is another dreadful virus that originates from STOP/DJVU family. As the name implies, it alters filename and add .gord extension as suffix. But do not be mistaken that this modification is the reason why all infected files are inaccessible because Grod ransomware initially encrypts them with highly complex algorithm. This is the usual file-locking process being used by all types of ransom virus to deny users access to their own files. In that instance, attackers may be able to demand payment in exchange for decryption software and private key, which are required to recover all .grod files.
Victim’s chances of restoring infected files without paying the ransom depend on how the virus applies cipher keys. If Grod cannot communicate to remote command-and-control server during the infection, it will utilize the local (offline) keys to decrypt targeted files. In cases like this, there is higher possibility that .grod files will be able to decrypt using tools provided by malware researchers, while free recovery for files that were locked with online keys are not feasible.
Having the thought of retrieving the entire affected files by paying the ransom money is somehow not conclusive. Keep in mind that dealing with cyber crooks whose main intention is to swindle money does not work for the benefit of end-users most of the time. The reason for these online criminals in utilizing discrete payment processor is to remain untraceable if ever they flee away after receiving the ransom payment.
Suggestions of computer security experts are to hold on to the file while waiting for official decryption tool for Grod ransomware. According to them, it is better to archive all .grod files and focus on the removal of virus to avoid infecting new or clean files.
