What is RomCom?

RomCom is the name of a Remote Access Trojan (RAT). Malware categorized as such is designed to enable remote access/control over infected machines. RATs can be highly multifunctional and thus pose a wide variety of threats.

RomCom malware overview

As mentioned in the introduction, RomCom is a RAT - a type of malware that allows remote access and control over compromised devices. These trojans can create close to or user-level control. RATs can execute a broad range of commands on infected machines, which can be used to carry out a variety of malicious activities.

Previous versions of RomCom differ little from the latest ones as far as functionality is concerned; the trojan's newest iterations have improved obfuscation and anti-detection capabilities. Much like its older variants, RomCom's primary goal is to steal data. It can obtain information relating to the device, disks, system/user files, and installed programs. Another ability that this RAT has is taking screenshots.

However, it must be mentioned that malware developers often improve upon and update their creations - hence, it is not unlikely that later versions of this malware will have additional/other functionalities.

The threats posed by malicious software infections depend not only on the program's capabilities but also on the attackers' goals.

Generally, the presence of software like RomCom on devices can result in serious privacy issues, financial losses, and identity theft. However, RomCom has been used in geopolitically-motivated attacks - the consequences of which can be much more severe.

If a RomCom RAT infection is suspected, we highly recommend using an anti-virus to remove it without delay.

Malware in general

We have analyzed thousands of malware samples; ArrowRATHyperBroRokRAT, and Trochilus are merely some of our newest finds within the RAT category. And BobikPowerShell RATPterodo - are a few examples of programs that have been used in attacks against Ukraine and its allies.

It must be stressed that regardless of how malware operates - its presence on a system endangers device and user safety. Therefore, all threats must be eliminated immediately upon detection.

How did RomCom infiltrate my computer?

RomCom has been observed being promoted on fake websites that closely mimic official ones of legitimate software such as the Advanced IP Scanner, PDF Filler, and others. Its campaign that targeted Ukrainian military institutions was proliferated through spam emails that copied the language used in genuine communication formats used in this sphere. It is pertinent to mention that RomCom may be spread using other techniques as well.

Malware is usually distributed by employing phishing and social engineering tactics. Malicious software can be presented as or bundled with ordinary programs/media.

Virulent files can be Microsoft Office and PDF documents, archives, executables, JavaScript, etc. Once a malicious file is executed, run, or otherwise opened - the infection process is initiated.

Malware is primarily proliferated via malicious attachments or links in spam mail (e.g., emails, PMs/DMs, etc.), drive-by (stealthy/deceptive) downloads, online scams, dubious download channels (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.), illegal program activation tools ("cracks"), malvertising, and fake updates.

How to avoid installation of malware?

We strongly recommend being careful with incoming emails and other messages. The attachments and links present in suspicious/irrelevant mail - must not be opened as they can be malicious and cause infections. It is essential to be vigilant when browsing since dangerous online content typically appears legitimate and harmless.

Another recommendation is to download only from official and trustworthy sources. Software must be activated and updated using genuine functions/tools, as illegal activation ("cracking") tools and third-party updaters may contain malware.

It is paramount to have a reputable anti-virus installed and kept up-to-date. Security programs 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.

Update 4 November 22: Cybercriminals have been observed using trojanized versions of SolarWinds Network Performance Monitor, KeePass password manager, and PDF Reader Pro programs to trick users into infecting computers with RomCom RAT. They use deceptive websites to distribute rogue versions of the software mentioned above.

It is also known that RomCom RAT is distributed via a fake Veeam Backup & Replication software installer.

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.
