Removal instructions for the Ice Breaker malware
Written by Tomas Meskauskas on (updated)
What is Ice Breaker?
Ice Breaker is a backdoor-type malware written in Node.js. Campaigns involving this malicious program were first identified in 2022 by Security Joes. These attacks targeted the gaming and gambling industries and were particularly recognizable due to the social engineering techniques employed by the cyber criminals.
At the time of writing, the threat actors behind Ice Breaker campaigns are not identified as belonging to a specific hacker group or geographical region. However, there is evidence suggesting that these criminals are not native English speakers.
Ice Breaker malware overview
The observed Ice Breaker campaigns began with threat actors seeking the assistance of support channels for gaming/gambling platforms. The support had to be human-operated, and the cyber criminals showed a preference for non-native English speakers – even if they themselves were not fluent in the requested language. This choice could be made to hide the criminals' ineptitude with the English language and/or keep communication to a minimum.
Typically, the targeted support was presented with false claims regarding unsuccessful attempts at logging in or registering a new account. As an explanation of the bogus error, the cyber criminals sent "screenshots" via download links.
In most cases, the malicious files were hosted on fake file-hosting sites that mimicked legitimate ones, especially the URLs with the use of lookalike characters (IDN homograph attack). However, the Dropbox hosting service was used as well. The threat actors aimed for support to open the malicious file. The main one used by the criminals was an LNK file, and only if the deception failed did they resort to sharing a download link for a VBS file.
The latter is designed to infect devices with the DUNIHI malware. The former is disguised with a filename expected of a screenshot and the image file icon used by Windows. After this LNK file is opened, it initiates a credential-seeking process and uses reverse shell to further the infection chain culminating in a Ice Breaker infection.
Ice Breaker uses various anti-analysis measures (e.g., decoy file dumping, masquerading as legitimate software, etc.) to complicate detection and reverse engineering efforts.
Following successful infiltration, this malware can exfiltrate files, extract Internet cookies and usernames/passwords from browsers (notably Google Chrome), and take screenshots.
It must be mentioned that malware developers often update their creations; hence, future variants of Ice Breaker are likely to have additional/different abilities.
In summary, the presence of software like Ice Breaker on a system can cause serious privacy issues, financial losses, and identity theft. Since this malicious program has been used to target businesses, the consequences of these attacks can be especially severe.
If you believe that your system is infected with Ice Breaker (or other malware) – we strongly recommend performing a full system scan with an anti-virus and removing it without delay.

Malware in general
We have analyzed thousands of malware samples; GoogleUpdate malware, zgRAT, PrintManager, Creal, PY#RATION, Album Stealer – are just some of our newest finds.
Malicious software can have a wide variety of capabilities and uses. It can be designed to steal information, cause chain infections, encrypt data for ransom purposes (ransomware), monitor victims, abuse system resources to mine cryptocurrency (cryptominers), etc.
However, regardless of how malware operates – the presence of this software on a system threatens device integrity and user safety. Therefore, we highly recommend eliminating threats immediately upon detection.
How did Ice Breaker infiltrate my computer?
As previously described, Ice Breaker has been observed being proliferated by employing social engineering tactics. In the researched campaigns, this malware was used to target the gambling and gaming industries. The threat actors sought to trick human-operated support into downloading and opening malicious LNK or VBS files. The former infected devices with Ice Breaker, while the latter with DUNIHI.
However, it must be mentioned that other distribution methods are not unlikely. In most cases, malware is spread using phishing and social engineering. Infectious files are usually disguised as or bundled with ordinary content. In the case of Ice Breaker, the files bore names implying that they were screenshots and used Windows image file icons.
The most widely used malware distribution techniques include: drive-by downloads, malicious attachments/links in spam emails and messages, dubious download channels (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.), online scams, malvertising, illegal program activation ("cracking") tools, and fake updates.
How to avoid installation of malware?
We recommend exercising caution with incoming emails and other messages. The attachments or links found in suspicious/irrelevant mail must not be opened, as they can be infectious. Another recommendation is to be careful when browsing since fake and malicious online content usually appears ordinary and innocuous.
We also advise downloading only from official and trustworthy sources. It is just as important to activate and update programs by using functions/tools provided by legitimate developers, as illegal activation tools ("cracks") and third-party updaters can contain malware.
We must emphasize that having a reputable anti-virus installed and updated is paramount to device/user safety. Security software 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.

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.
