What is HyperBro?

HyperBro is the name of a Remote Access Trojan (RAT). This type of malware is designed to allow remote access/control over infected machines. RATs are typically highly functional pieces of malicious software capable of causing all sorts of severe issues.

It is noteworthy that HyperBro has been used in an attack against the United States Defense Industrial Base (DIB) sector.

HyperBro malware overview

As mentioned in the introduction, HyperBro operates by enabling remote access and control over compromised machines. It can execute various commands on infected systems.

This malware begins its operations by collecting relevant device data, e.g., computer name, user access level/ privileges, IP address (geolocation), etc. HyperBro attempts to escalate itself to full admin privileges, and it ensures persistence by auto-starting upon user log-in.

This trojan can steal files and data. It accomplishes the latter by using its keylogging abilities to record keystrokes. In addition to downloading files, the RAT can upload and execute them. Hence, it could be used to cause chain infections, i.e., install additional trojans, ransomware, and other malicious programs.

Therefore, the presence of HyperBro on devices may lead to multiple system infections, data loss, serious privacy issues, financial losses, and even identity theft. Furthermore, malware used to facilitate cyber espionage or other politically/geopolitically motivated attacks can carry particularly severe consequences.

If you suspect that your device is infected with the HyperBro RAT (or other malware) - we strongly recommend using an anti-virus to eliminate it without delay.

Remote access trojan examples

We have analyzed countless malware samples; RokRAT, TrochilusDeed9002TigerRAT, and Bobik are just some examples of RATs.

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

How did HyperBro infiltrate my computer?

Malware is proliferated using phishing and social engineering tactics. Malicious programs are usually disguised as or bundled with ordinary content. Virulent files can be archives, executables, Microsoft Office and PDF documents, JavaScript, etc. When such a file is executed, run, or otherwise opened - the infection process is initiated.

The most common malware proliferation methods include: drive-by (deceptive/stealthy) downloads, malicious attachments/links in spam emails and messages, online scams, dubious download channels (e.g., freeware and third-party websites, P2P sharing networks, etc.), illegal program activation tools ("cracks"), malvertising, and fake updates.

How to avoid installation of malware?

We highly recommend being careful with incoming mail. The attachments and links present in suspicious/irrelevant emails and messages must not be opened, as they can be malicious and cause system infections.

It is crucial to download only from official and verified sources. Furthermore, all programs must be activated and updated using genuine functions/tools, as illegal activation ("cracking") tools and third-party updaters can contain malware.

Another recommendation is to be vigilant when browsing since fraudulent and malicious content usually appears legitimate and innocuous.

We must emphasize the importance of having a reputable anti-virus installed and kept up-to-date. This software must be used to run regular system scans and to remove detected threats. 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.
