KPOT Stealer

Also Known As: KPOT trojan
Type: Trojan
Damage level: Severe

What is KPOT?

Discovered by Jorge Mieres, KPOT is a high-risk trojan designed to steal various personal information. This malware is typically distributed using fake web browser updaters (more information), however, this trojan was previously distributed using spam email campaigns.

KPOT can be purchased for $100 on hacker forums and, therefore, any aspiring cyber criminal can purchase this trojan and begin stealing data.

KPOT malware

The main purpose of KPOT is to gather personal information. To be specific, it targets account credentials saved in various applications (e.g., Skype, Discord, Steam, FTP clients, etc.), web browsing data (cookies, passwords, autofill data), and even cryptowallets (cryptocurrency files). With access to this information, cyber criminals can cause significant issues.

Firstly, hijacked accounts might be used to proliferate this malware even further by sending spam. Additionally, cryptocurrency wallets and other accounts might be misused through online purchases, money transfers, borrowing money from the victim's contacts, and so on. Therefore, having KPOT installed can lead to financial loss and even debt.

Bear in mind that criminals also attempt to steal FTP credentials. They might gain access to various servers managed or owned by the victim. This can also cause various issues (e.g., data loss, permanently damaged/shutdown websites and servers, etc.).

These problems are not only inconvenient, but could also result in financial loss, especially if the damaged website/server is used to generate revenue or serves as a communication/development tool in various companies.

In summary, the presence of a high-risk trojan can lead to serious privacy issues (including identity theft), data/financial loss, and other problems. We strongly recommend that you eliminate this trojan immediately.

There are dozens of trojan-type infections that share similarities with KPOT including, for example, Racoon Stealer, Evital, and Atilla Stealer - these are just some examples from many.

These infections are specifically designed to steal information, however, there are dozens of other trojan-type infections that perform other malicious actions (e.g., inject malware into the system, mine cryptocurrencies, connect infected computers to botnets, and so on), however, no matter which trojan has infiltrated your computer, you should remove it immediately.

How did KPOT infiltrate my computer?

As mentioned above, KPOT is mostly proliferated using fake browser updaters and spam email campaigns. Fake updaters are promoted through deceptive websites that display pop-up messages. These falsely claim that the web browser is outdated and that the user should update it immediately.

These pop-ups also contain an "Update" button, which downloads the malicious updater designed to inject KPOT into the system. Spam campaigns, on the other hand, are used to send hundreds of thousands of emails consisting of malicious attachments (typically, Microsoft Office documents or PDF files), and messages encouraging users to open them.

Criminals are also likely to present malicious attachments as important documents (e.g., receipts, invoices, etc.). This is done to give the impression of legitimacy and increase the chance of tricking users into opening the files.

Trojans are often proliferated using fake software 'cracks', third party software download sources (free file hosting websites, freeware download websites, Peer-to-Peer [P2P] networks, and similar), and other trojans (chain infections).

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the Internet and downloading/installing/updating software. Handle all email attachments with care. Files/links from suspicious/unrecognizable email addresses should not be opened. Attachments that are irrelevant and do not concern you should be ignored.

Download apps from official sources only, using direct download links. Additionally, keep installed applications and operating systems up-to-date. To achieve this, use only implemented functions or tools provided by the official developer. Third party downloaders/installers/updaters are often used to include rogue apps, and thus these tools should never be used.

As mentioned above, software cracks are used to proliferate infections. Note also that software piracy is illegal (a cyber crime) and, therefore, you should never attempt to crack installed apps. Finally, have a reputable anti-virus/anti-spyware suite installed and running at all times.

These programs detect and eliminate malware before it harms the system. The key to computer safety is caution. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Update April 2, 2020 - Cyber criminals have recently started a new malware distribution campaign which targets mostly South Korean and Japanese users. They've released a number of coronavirus-related websites (including corvir[.]london and covid19onlineinfo[.]com) designed to use Fallout Exploit Kit in order to inject KPOT stealer into the system.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check 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".

locate the malware file you want to remove

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.

searching for malware file on your computer

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.
