Deed RAT overview

As a remote access trojan - Deed operates by enabling remote access/control over compromised machines. Typically, these malicious programs are multifunctional and allow for near-to or user-level control over devices.

Deed collects system data, but as a RAT - it may also be capable of downloading user files and/or extracting private data from browsers and other installed applications. This trojan can also monitor and interact with the Windows Registry - a database containing information (e.g., settings, options, etc.) relating to hardware and installed programs.

Many RAT-types can infiltrate and execute files - this ability allows the malware to cause chain infections. Hence, victims can experience additional trojan, ransomware, cryptocurrency miner, and other malware infections.

In summary, the presence of software like Deed RAT on devices can result in severe privacy issues, data loss, significant financial losses, and even identity theft. If you suspect that your device is infected with this or other malicious software - we strongly advise you to use an anti-virus to remove it without delay.

Remote access trojan examples

We have analyzed countless malware samples; TigerRAT9002 RAT, and Bobik are merely a few of our latest RAT finds. Remote access trojan infections are considered to be especially hazardous due to this malware typically having a wide variety of functionalities and uses. However, regardless of how malicious software operates - its presence endangers device integrity and user safety.

How did Deed RAT infiltrate my computer?

Malware is usually spread by employing phishing and social engineering tactics. Cyber criminals tend to disguise this software or bundle it with regular content.

Malicious files can be archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), Microsoft Office and PDF documents, JavaScript, and so forth. System infection processes are triggered when a virulent file is executed, run, or otherwise opened.

The most common proliferation techniques include: drive-by (stealthy and deceptive) downloads, malicious attachments/links in spam emails and messages, online scams, dubious download channels (e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc.), illegal software activation tools ("cracks"), malvertising, and fake updates.

How to avoid installation of malware?

We highly recommend downloading only from official and trustworthy sources. Furthermore, software must be activated and updated using functions/tools provided by legitimate developers, as illegal activation tools ("cracks") and fake updates may contain malware.

We advise against opening the attachments/links present in suspicious emails and messages since that can result in a system infection. Another recommendation is to exercise caution when browsing since illegitimate and malicious content typically appears harmless.

We must emphasize the importance of having a dependable anti-virus installed and updated. Security programs must be used to run 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.

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".

Delete malware in Autoruns

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.

Search for malware and delete 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.
