Kodg ransomware virus

That item is about virus called Kodg which gets onto customers' laptops around the world, and cyphers the data. Here you will find complete information on what is Kodg, and how to delete Kodg from your workstation. Except that, we'll tell you how to restore the encrypted data, if possible.

Kodg is the perilous program penetrating PC's mainly via e-mail spam and Trojans. Also, fraudsters use zero-day vulnerabilities to get into the PC, but they are quickly corrected. After penetration, ransomware inspects the hard drive, defines the number of files to be cyphered and their rough worth. Currently, any new virus can encrypt image, audio, video and text info in all known formats. Kodg cyphers all folders, but those that look like business documents go first. Virus encrypts only information, and doesn't spoil the software, so that the user can pay the ransom via his PC. The process is executed through famous AES and RSA algorithms, and its intricacy is so high that it can't be bruteforced. This is the root for impressive success of ransomware in last years: common PC operator, even having a very good knowledge of the PC, will never be able to get back the data, and will need to pay the price. The only manner to get back the data is to hack the scam website and obtain the master key. Also there's a chance to retrieve encryption keys via defects in viruse's program code.

The other efficient sort of these letters is a "business messages". It is natural to be interested and click on the letter even if it might be not for you, but don't forget that one click on the attached file can cost you a lot of time, efforts and money.
    • Keep an eye on the state of your PC. It consumes a lot of CPU resources to encrypt the files. In the first minutes after the infection, the CPU speed decreases, and the encrypting process emerges in Process Manager. You may anticipate this moment and shut down the computer before information will be completely encrypted. These measures, in case of penetration, will protect a lot of your data.
    • Take notice to the dialog boxes. If the computer is penetrated by Kodg, it will attempt to delete the shadow copies of your files, to make the decryption impossible. The deleting of copies needs admin rights and verification from the operator. The second of thinking before verifying the changes might save your information and your money.
