Written by Tomas Meskauskas on
What kind of malware is Kraken?
Kraken is a malware that empowers threat actors to illicitly acquire diverse sensitive information from different web browsers and applications. The creators of Kraken offer it for sale on a hacker forum, with pricing options of $29 for 30 days, $49 for 90 days, and $69 for 180 days. Cybercriminals have been observed distributing Kraken through email.
More about Kraken
The Kraken malware possesses multiple functions that can be executed. These functions allow threat actors to execute specific actions or commands at predetermined intervals or at a specified time, load and interact with web content, disable or terminate specific system tasks or processes, disable the Windows Command Prompt, disable Windows Registry, and terminate specific processes running on the infected system.
The Kraken malware follows a typical approach of an information stealer by targeting and stealing credentials from various email clients and web browsers. Specifically, it focuses on stealing login credentials from popular email clients like Outlook, Foxmail, and Thunderbird.
Additionally, it searches for credentials in a wide range of web browsers, including 360Browser, Avast Browser, Blisk, Brave, Cent Browser, Chedot Browser, Chromium Browser, Citrio Browser, CocCoc, CoolNovo, Edge, Epic Privacy Browser, Firefox, Google Chrome, Google Chrome Canary, Opera, QQ Browser, Torch, UC Browser, Vivaldi Browser, among others.
Furthermore, the Kraken malware also looks for FileZilla credentials, which is an FTP client used for transferring files. The Kraken malware provides functionality for exfiltration, allowing data to be transferred through different channels. It supports exfiltration via three specific methods: FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), and Telegram Bot.
Once the data theft process is complete, the Kraken malware initiates an automated process that involves keylogging and capturing screenshots of the victim's computer. Keylogging is a method employed by malware to record and capture every keystroke typed on a compromised device, including sensitive information such as passwords, credit card numbers, and personal messages.

|Symptoms||Typically, information stealers are designed to stealthily infiltrate the victim's computer and remain silent, and thus no particular symptoms are clearly visible on an infected machine.|
|Distribution methods||Infected email attachments, malicious online advertisements, social engineering, software 'cracks'.|
|Damage||Stolen passwords and banking information, identity theft, monetary loss, loss of access to online accounts, and more.|

Kraken can cause various problems for its victims. For instance, it can lead to the theft of sensitive information, such as login credentials, personal data, and financial details, compromising the victim's privacy and potentially resulting in identity theft or financial loss. Kraken's keylogging and screenshot-capturing capabilities can expose private conversations, confidential files, and other sensitive information to unauthorized individuals.
More examples of malware with information-stealing capabilities are Offx, Warp, and ObserverStealer.

Kraken malware can be distributed through various methods. One known distribution method is through email campaigns, where cybercriminals send phishing emails with malicious attachments or links.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.
These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
