This article explains the issues that occur in case of infection with Kraken Cryptor v2.2 and provides a complete guide on how to remove malicious files and how to potentially recover files encrypted by this ransomware.
Kraken Cryptor v2.2 is a strain of a ransomware family of the same name. The purpose of this threat is to invade computer systems and then encodes files stored on them by utilizing a strong cipher algorithm. During the encryption process, Kraken v2.2 ransomware changes parts of the original code of target files and appends five random capitalized letters and numbers as an extension. Following encryption, all corrupted files remain inaccessible until any efficient recovery solution restores the initial state of their code. One decryption option is offered by hackers at a price of $80. However, since at this point there is no evidence that they possess a working decryptor, it is better to consider the use of alternative recovery methods. You can find a list of the ones proved to be efficient in this removal guide.

Kraken Cryptor v2.2 Ransomware – Distribution
An infection with Kraken Cryptor 2.2 begins when its payload is activated on the system. This file is usually spread via:
- Email spam campaigns
- Links to corrupted web pages
- Malicious advertising
- Fake software updates
- Freeware installers
Massive email spam campaigns are considered to be the main technique used for the distribution of Kraken Cryptor 2.2 ransomware. Emails included in these campaigns could pose as representatives of legitimate services in order to make you more prone to activate the ransomware on your device. Where the ransomware payload code could reside is in an attached file or corrupted web page that is accessible through an URL address presented in the text message.
In September security experts discovered that hackers have used the [wplinkpreview url=”https://sensorstechforum.com/kraken-ransomware-attacks-fallout-exploit-kit-attacks/”]Fallout Exploit Kit to spread the payload files of previous Kraken ransomware iterations. Fallout is a sophisticated exploit kit that triggers a series of events in order to enable hackers to gain control over computer systems. It automatically and at the same time unnoticeably exploits present browser and system vulnerabilities. A successful exploit leads to the activation of Kraken ransomware payload directly on the system.
Kraken Cryptor v2.2 Ransomware – Overview
Soon after Kraken Cryptor v2.2 ransomware payload is activated on a target system it initiates a sequence of malicious modifications that enable it to complete all infection stages.
At first, it could attempt to detect if any security tools are currently running on the system and eventually take control over some legitimate system processes that will enable it to evade detection. Then the ransomware could attempt to send a connection request to its command and control server. The purposes of this action may be the delivery of additional ransomware files or other malware files on the system, the transfer of harvested system data such as type and version of operating system, installed browsers, active applications, and sometimes even login credentials.
Files associated with Kraken Cryptor v2.2 might be stored in some of the following folder locations:
- %Roaming%
- %Windows%
- %AppData%
- %Local%
- %Temp%
The ransomware is also likely to attempt to add malicious values under the Run and RunOnce registry sub-keys as their functionalities could enable it to start its files on each system start. In addition, the same keys may store values associated with the desktop ransom note of Kraken Cryptor v2.2 which in turn results in its automatic display on the screen at the end of the infection process.
The text on it reads:
Kraken Cryptor v2.2!
Dear [user name] All your files such as documents, images, videos and other files
With the different named and extensions are encrypted.Read the instructions file named “Instructions-[extension]” for more information.
You can find this file everywhere on your computer.*Don’t Delete Encrypted Files
*Don’t Modify Encrypted Files
*Don’t Rename Encrypted Files
After this wallpaper appears on screen voice-over messages start repeating the text depicted on it.
The mentioned file Instructions-[extension] contains further instructions on how to pay the ransom and eventually receive a decrypter. At this point, it is known that authors of this Kraken version demand a payment of $80. Probably the amount should be converted in Bitcoin and then send to their Bitcoin address.
For the sake of your security, we advise you to avoid contacting hackers and following their instructions as except your files you may lose your money too.
Kraken Cryptor v2.2 Ransomware – Encryption Phase
When Kraken Cryptor v2.2 ransomware applies all needed system modifications it is ready to trigger the main infection stage. This stage is considered to be data encryption as it enables hackers to extort a ransom payment from affected users.
For this stage, the ransomware activates its built-in encryption module. It is set to utilize strong cipher algorithm that modifies parts of the original code of target files and appends an extension of five random A-Z O-9 characters to each corrupted file. Unfortunately, like previous Kraken ransomware versions ([wplinkpreview url=”https://sensorstechforum.com/lock-onion-files-virus-kraken-cryptor-remove-restore-data/”]KRAKEN CRYPTOR and [wplinkpreview url=”https://sensorstechforum.com/remove-kraken-cryptor-v2-0-7/”]Kraken Cryptor v2.0.7) Kraken Cryptor v2.2 encodes types of files that usually store valuable information. Eventually, you may have all of the following files encrypted by the threat:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
