Kraken Cryptor 2.2 virus Removal Guide
What is Kraken Cryptor 2.2 ransomware?
Kraken Cryptor 2.2 ransomware is a cryptovirus that mimics the ransom note of Cerber virus
Kraken Cryptor 2.2 ransomware is a cryptovirus that demands $80 in Bitcoin for alleged decryption.
Kraken Cryptor 2.2 ransomware is a cryptovirus that uses a combination of algorithms to encrypt data on the infected device. It hails from the Kraken Cryptor family that started its activity in August of 2018 and already has eight versions. This particular version encrypts data and marks files with extension consisting of five random characters. Virus developers demand $80 for file recovery, but we don't recommend falling into this trap. After sending your money to Kraken Cryptor 2.2 ransomware developers, you can be left with no money and no files. The ransom and other details are typically provided in the ransom message that is displayed on the desktop. This particular version of a ransom message seems to be a clear replica of Cerber virus as victim's Desktop changed to the almost identical ransom note and cover.
|Name||Kraken Cryptor 2.2 ransomware|
|File extension||Random five characters|
|Ransom note||Displayed on a changed Desktop background.|
|Encryption algorithm||Based on previous versions – a combination of AES-128/256, RSA, Salsa20, and RC4|
|Distribution||Spam email attachments, exploit kits|
|Removal||Download and use Malwarebytes for Kraken Cryptor 2.2 ransomware elimination|
Kraken Cryptor 2.2 ransomware virus payload is activated when the malicious file gets on the targeted system and initiates the ransomware script. It enables a sequence of system modifications and all infections stages. Encryption is not the first stage of the ransomware attack.
The first step Kraken Cryptor 2.2 ransomware does on the infected device is adding files to various system folders. Data associated with this threat that can keep it more persistent can be stored in:
When additional changes are made on the system, Kraken Cryptor 2.2 ransomware starts the encryption process during which the data in various forms gets locked in a matter of seconds and marked with file appendix in a random character pattern.
Then the ransom message is placed as a Desktop background, and as soon as this happens, the voice-over message starts repeating the written text. This ransom note delivered by Kraken Cryptor 2.2 ransomware displays the following:
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
The file mentioned in this ransom note contains direct instructions on the payment method and states that the ransom amount is $80. Money should be converted in Bitcoin cryptocurrency and send to the cryptocurrency address that hackers provided.
You need to remove Kraken Cryptor 2.2 ransomware because it additionally modifies registry entries under Run or RunOnce sub-keys. This modification is made so the functionality of the ransomware could enable the process on each system reboot. Same keys may also store values associated with the ransom note displayed on the Desktop which initiates the voice-over automatically.
Kraken Cryptor 2.2 ransomware removal is not an easy process especially when the virus detection rate is not promising positive results. Use Malwarebytes for automatic Kraken Cryptor 2.2 ransomware removal and scan the device using RestoroIntego or any other system optimization tool to make sure that virus damage is removed.
Kraken Cryptor 2.2 ransomware is a cyber threat developed by hackers known since August 2018.
Previous versions use spam email attachments and exploit kits to spread the threat around
The primary technique used to distribute crypto-extortion based malware is insecure email attachments. The payload is activated on the system when the malicious script is added and opened on the network. These emails could pose as the official company or legitimate service to make the user more trusting to open the attached file.
Unfortunately, this ransomware payload can be added to safe-looking MS Word or Excel files and the minute you download the attached document and open it on the computer malicious malware loads on the system.
However, recently researchers discovered that hackers responsible for this cyber threat used Fallout exploit kit to spread the malicious script of previous versions. This is a sophisticated technique that triggers a series of malicious events to allow hackers to gain control over the system of the infected device. This is unnoticeable and automatic, so this method leads to the activation of ransomware directly on the system.
Terminate Kraken Cryptor 2.2 ransomware and clean the system further using professional tools
To remove Kraken Cryptor 2.2 ransomware from the system completely, use RestoroIntego, SpyHunter 5Combo Cleaner or Malwarebytes.

Kraken Cryptor 2.2 ransomware removal is giving better results when performed with reputable tools. The manual virus elimination is not advisable, especially when it comes to notorious threats like this ransomware family. You may also need to enter the Safe Mode with Networking before scanning the system thoroughly because the virus is persistent and makes various changes on the system.

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
