How to remove the TigerRAT malware from your operating system
Written by Tomas Meskauskas on
What is TigerRAT?
TigerRAT is a Remote Access Trojan (RAT). This malware operates by allowing attackers to remotely access and control infected machines. RATs are notoriously multifunctional programs, which can be variously used and cause a broad range of serious threats.
There is proof that TigerRAT was developed and is used by the Lazarus group, a threat actor that is considered to be under the sponsorship of the North Korean state.
TigerRAT malware overview
It is noteworthy that TigerRAT has been observed being injected into systems by MagicRAT - another program from the arsenal of the Lazarus group. Following successful infiltration, TigerRAT begins collecting relevant device data, such as device name, operating system version, account username, information relating to the network interface, etc.
In addition to carrying out various malicious actions on machines, this trojan can manage files (e.g., read, create, write, delete, and download). Other information stealing abilities include screen recording and keylogging (keyboard input recording).
There is also evidence in TigerRAT's code of attempts to implement video recording features (i.e., footage capture via attached/integrated cameras). At the time of writing, there have been no versions of TigerRAT discovered where these functionalities are fully operational.
However, Lazarus group - the developers of this RAT are known to continuously add, remove, and modify the features of their creations - therefore, it is not unlikely that variants of TigerRAT will sport different abilities.
To summarize, infections of this kind can lead to severe privacy issues, financial losses, and identity theft.
If you suspect that your system is infected with TigerRAT (or other malware) - we advise using an anti-virus and removing it immediately.

Remote Access Trojan examples
Bobik, Escanor (Esca), Aurora, VileRAT, and Woody are merely some examples of the RATs that we have analyzed recently.
Malicious programs within this classification can have various functionalities ranging from data exfiltration to download/installation of additional malware. However, the presence of malware on systems endangers device/user safety regardless of how it operates.
How did TigerRAT infiltrate my computer?
Malware is spread using phishing and social engineering tactics. Malicious programs are typically disguised as or bundled with ordinary software/media.
The most widely used distribution techniques include: drive-by (stealthy/deceptive) downloads, online scams, malicious attachments and links in spam emails/messages, dubious download sources (e.g., unofficial and freeware websites, P2P sharing networks, etc.), illegal software activation ("cracking") tools, and fake updates.
How to avoid installation of malware?
We strongly advise against opening the attachments/links found in suspicious emails and messages - since that can result in a system infection.
Furthermore, all downloads must be performed from official and verified channels. It is crucial to activate and update software using functions/tools provided by legitimate developers, as illegal activation tools ("cracks") and third-party updaters may contain malware.
We must stress the importance of having a reputable anti-virus installed and kept updated. This software must be used to perform regular system scans and to remove threats and issues. 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.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.
If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup.
Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings".
Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

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.
