The KratosCrypt Ransomware is an encryption ransomware Trojan that con artists use to take over a computer. The KratosCrypt Ransomware is installed without the victim's knowledge. Once installed, the KratosCrypt Ransomware encrypts the victim's files using a strong encryption algorithm. The KratosCrypt Ransomware can be identified from countless similar infections because the KratosCrypt Ransomware appends the extension 'KRATOS' to all files that it encrypts. After the KratosCrypt Ransomware encrypts the victim's files, it creates an HTML file named 'README_ALL' on the victim's computer. This HTML file is dropped in every directory where a file was encrypted by the KratosCrypt Ransomware. The file contains the KratosCrypt Ransomware's ransom note, with instructions on how to pay the ransom and information on how the attack was carried out.

The Ransom Note Displayed by the KratosCrypt Ransomware

The KratosCrypt Ransomware's ransom note simply states that the victim's files were encrypted. To recover from the KratosCrypt Ransomware attack, victims must pay 0.03 BitCoin, which at the time of writing is $20 USD approximately. This is an extraordinarily small amount when compared with other ransomware Trojans. Most ransomware Trojans demand ransoms equivalent to 0.5 – 1.5 BitCoins, which may mean hundreds or thousands of dollars. It may be that the con artists responsible for the KratosCrypt Ransomware are trusting that victims of this attack are willing to pay the small ransom amount instead of going through the inconvenience of restoring their files from a backup or looking for a decryptor online.

The KratosCrypt Ransomware uses a strong decryption method that stores a private decryption key on the Command and Control servers associated with the KratosCrypt Ransomware. Fortunately, PC security analysts have developed a brute force gadget that is capable of generating a private key for the KratosCrypt Ransomware and similar threats. Because of this, there is no need to pay the ransom associated with this threat. Even if the decryptor weren't available, it is not recommended that computer users pay the ransom. Since the people responsible for the KratosCrypt Ransomware are con artists and completely untrustworthy, there is absolutely no guarantee that they will keep their promise after the computer users pay the ransom amount. Apart from this, paying the KratosCrypt Ransomware's ransom allows con artists to continue creating and distributing their harmful threats.

Preventing the KratosCrypt Ransomware Attacks

The best way to prevent the KratosCrypt Ransomware attack is to backup all important files. PC security analysts also recommend that computer users use a reliable security program that is fully up-to-date to ensure that the KratosCrypt Ransomware and similar threats don't enter a computer in the first place. It may not be possible to recover from most ransomware threats; the KratosCrypt Ransomware is, in fact, an exception due to the availability of a decryptor. Because of this, prevention through the use of good security practices and behaviors is the best method to avoid becoming a victim of these threats.
