Remove ATKL ransomware (Removal Guide) - Decryption Methods Included

removal by Alice Woods - - | Type: Ransomware

ATKL ransomware is the dangerous malware because it contaminates systems and causes serious problems besides file encryption

ATKL ransomwareATKL ransomware – cryptovirus that drops random files on the machine, interferes with processes, applications, and programs to avoid quick virus termination or file recovery. It locks commonly used files and demands payment from victims promising to send the decryption tool after that. However, this is a version of Matrix ransomware that is known for more than a few years, and none of the variants can be decrypted. As a typical ransomware-type virus, this threat starts with file encryption and money demand, so when the time for payment ends, the system is affected in various ways. Cybercriminals change the original code of the image, document, audio, or video file and then marks the affected data using .ATKL extension with the contact email address. For example, if your Image.jpg file gets locked it becomes Image.jpg.[atomickule@cock.li].[random_string].ATKL. The email address may change because criminals provide at least three of them (atomickule@cock.li, atomickule@tutanota.com, and atomickule@protonmail.com). 

ATKL ransomware virus developers encourage people to contact them via these emails and do that as soon as possible, so the payment can become a decryption possibility, as they claim. We don't recommend trusting these people because malicious actors have their own goals of getting money directly from you and stealing possibly valuable data from machines and other accounts online. All these instructions, claims, and promises get listed in the ransom message that appears as a !ATKL_README!.rtf file on the screen. Do not fall for the test decryption possibility and keep away from these people at all. Contacting them alone can bring more issues, additional malware. The ransomware infection on its own can damage many parts of the computer, so clean the device as soon as possible.

Name ATKL ransomware
Family Matrix 
File marker .[atomickule@cock.li].[random_string].ATKL appears on the encrypted data and can differ from victim to victim because the email may get changed. The random string included in this pattern can be related to victims' ID listed on the ransom message file
Ransom note !ATKL_README!.rtf – the message encouraging people to pay the ransom for file decryption. This is a lengthy note containing instructions, contact information, offer for test decryption and your personal ID needed for the decryption
Contact emails atomickule@cock.li, atomickule@tutanota.com, and atomickule@protonmail.com
Additional feature The malware drops random files on the machine that can be found on the desktop and in other folders. There is no particular usage for them, and types of data differ
Danger This ransomware deletes Shadow Volume Copies to ensure that there are fewer options for data recovery and manages to alter or add new registry keys that interfere with system functions and applications running on the device. This s threat based on blackmailing, so anything can lead to money or data loss or permanent damage on the infected computer
Distribution This is the widespread threat that manages to distribute payload using exploit kits like RIG,[1] hacked sites, malicious pages, and infected files attached to emails. 
Elimination To remove ATKL ransomware completely, get a tool that can possibly detect[2] this malware and other associated applications or files and delete them completely 
Repair As for data affected by the virus. System files get damaged and corrupted, so various processes cannot run and help you with recovery and cleaning, so run Reimage Reimage Cleaner Intego and fix that damage, affected data and repair functions of the OS

ATKL ransomware makes files no longer accessible for users, so they cannot even know which data is valuable. It creates frustration and even panic because file restoring is almost impossible if you don't have any data backups on external devices or cloud services. Especially, when the ransom gets demanded for the alleged decryption options. The tool that criminals promise to have may not even exist, and the second your money gets transferred, they disappear without any opportunity to contact virus creators again. This is one of the main reasons to not communicate with threat actors.

Also, remember that ATKL ransomware is a version of the dangerous threat, so virus developers know how to avoid detections, encode files permanently and evade security, AV tools. This cryptovirus uses powerful encryption algorithms and modifies the structure of data, so there are no other options, but to pay the ransom. No matter how small it is – DO NOT PAY. 

There are too few chances that files affected by the threat will get recovered fully. You better remove ATKL ransomware and clean the machine, then go for the cleaning processes and system repair, data recovery. Before restoring anything, make sure that the threat is no longer active, and there is nothing possibly associated with the virus or additional malware. Your files may get permanently damaged if the virus runs another round of encryption.

ATKL ransomware starts with encryption, but this is not the only process it can run on the infected machine, so once you get this ransom demanding message, make sure to react and clean the system with anti-malware tools.

ATKL ransomware virus
ATKL ransomware - cryptovirus that relies on cryptography and malicious files that get added in various places to control the applications and performance.
Even though ATKL ransomware developers claim to offer you the decryption tool and even encourage to test decrypt 3 files, you shouldn't even bother and think about that. Ignore the message and remove the virus. You may store some of the encrypted files and virus-related data on a separate external device if you think that a decryption tool can be developed later on. However, the time is important with these threats because anything can get installed in the background without your knowledge and permission.

ATKL ransomware removal process gets difficult due to affected programs, security functions, and questionable files added in various places of the machine. It is unknown why and for what purpose those files and programs get added on the desktop, but malware can freely affect system processes launching applications and disabling running functions. You need to repair those features after virus termination too, so using Reimage Reimage Cleaner Intego can be crucial for the state of security. 

Such PC repair utilities or system optimizers can find and fix ATKL ransomware virus damage, affected or even corrupted files, functions. Make sure to take care of these issues before you go further with any data recovery options to avoid permanent damage or loss.

Also, ATKL ransomware belongs to a family of threats that distributes variants using sophisticated and powerful methods like exploit kits, hacked or malicious sites. Various vulnerable programs might get used to installing ransomware and other viruses like worms or information-stealing trojans. 

Proper termination procedures are needed to tackle all ATKL ransomware virus-associated intruders and malware, so rely on the anti-malware tools that can possibly detect such powerful viruses and remove them from the devices. For additional tips, we have prepared a few solutions below. Also, decryption options for those who have not backed up their data in advance.  ATKL cryptovirus
ATKL ransomware is the virus that marks data using contact email and identificational characters after encryption.

Sophisticated methods of spreading crypto-extortion based malware 

The infection like this can spread various ways, depending on the particular campaign and version of the threat, malicious actors. Spam email campaigns with infected email attachments that trigger macros[3] are more common for the ransomware viruses. Also, exploit kits, vulnerabilities, and malicious programs designed for dropping the payload are used more often than other techniques.

It is known that the particular ransomware family creates shortcuts on the infected machines to spread on other computers. The copy of the ransomware executable file gets hidden in the folder and modified into a shortcut. Once clicked it launches the program and executes ransomware that either encrypts files newly added on the same machine or infects another computer via network shares or removable drives.

It is known that these methods can be updated and changed quickly, so remain cautious and clean the email box more often, avoid opening any email notifications or files attached to the email and clean the machine from viruses and vulnerable applications more often using the proper system or security tools.

ATKL ransomware infection termination guide

Since this ATKL ransomware virus is one of many versions in the known and dangerous virus family, you should take the additional issues into consideration. Executable files, applications, and programs that get disabled all are results of the infection.

Ransomware ensures that you, as a victim, have fewer options for virus termination and even file recovery so malware can run longer on the machine. Make sure to remove ATKL ransomware as soon as you can and rely on proper anti-malware tools, don't look for an easy way out. 

We recommend going for automatic ATKL ransomware removal using SpyHunter 5Combo Cleaner or Malwarebytes because these security programs can find virus-related data and terminate those malicious processes for you. Also, tools like Reimage Reimage Cleaner Intego can ensure that nothing is missed and all OS functions are back to normal and running. Always double-check before adding anything new on the machine, especially before data recovery.
