What kind of malware is BitRAT?
BitRAT is a malicious program, classified as a Remote Access Trojan (RAT). Malware of this type enables remote access and control over an infected machine. RATs have a wide variety of dangerous functionality. While BitRAT is by far not the most sophisticated piece of malicious software available, nevertheless it is considered highly dangerous.
Therefore, BitRAT infections must be removed immediately upon detection. Since this Trojan is offered for sale by its developers, how it is spread depends on the methods preferred by the cyber criminals who have purchased it.
More about the BitRAT malware
As mentioned, remote access Trojans have a wide variety of malicious features, which can enable varied level of control and misuse of the infected device. These Trojans can gain control over integrated/connected hardware, installed software and content stored in or accessed through the infected computer.
According to BitRAT's promotional material, it is capable of controlling a machine's hardware: employ the device's keyboard and mouse, and possibly move the mouse live/in real-time; via webcams and microphones record video and audio, and stream them live. BitRAT can manage the files stored in the system to a certain degree.
It can exfiltrate and infiltrate (i.e. download and upload) files. The stolen data can then be used for ransom purpose. Furthermore, if the RAT's capability to execute uploaded files is successfully implemented, it may be used to cause chain infections (i.e. to download/install additional malware).
Similarly, BitRAT can stealthily use the browser (hidden/remote browser), specifically the Google Chrome browser. This malicious program can also extract stored log-in credentials (i.e. IDs, usernames and passwords) from browsers and other applications.
The promotional material states that the aforementioned feature of BitRAT is supported on over 35 browsers and more than 500 other different applications. This Trojan has keylogging capabilities.
Thus, it can record key strokes, a feature typically used to collect typed log-in credentials and other vulnerable data (e.g. names, addresses, telephone numbers, emails, banking account and/or credit card details, etc.). The BitRAT can function as a cryptominer as well, and is geared towards mining the Monero (XMR) cryptocurrency.
Whilst BitRAT is a sloppily-constructed malicious program with some of its functionality being nonoperational and detectable, this does not prevent its infections leading to victims experiencing financial loss, serious privacy issues and identity theft.
Therefore, if it is suspected or known that BitRAT (or other malware) has already infected the system, use anti-virus software to eliminate it without delay.

RATs in general
These types of Trojans have various capabilities, such as data extraction and exfiltration, download/installation of additional malicious programs, spying functionality (video/audio and key stroke recording), cryptocurrency mining, and so on. Regardless of how malware operates, it has just one goal - to generate revenue for the developers and cyber criminals using it.
How did BitRAT infiltrate my computer?
Malware is primarily distributed via spam campaigns, untrusted download channels, illegal activation tools ("cracks") and fake updates. The term "spam campaign" defines a large-scale operation, during which thousands of deceptive/scam emails are sent.
These messages are usually disguised as "official", "important", "urgent", and similar. They contain download links of infectious files and/or the files are simply attached to the emails.
Malicious programs are often downloaded unintentionally from dubious download sources such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders. Rather than activating licensed products, "cracking" tools can download/install malware.
Fake updaters infect systems by exploiting flaws of outdated products and/or by installing malicious software, rather than the promised updates.
How to avoid installation of malware
Suspicious or irrelevant emails must not be opened, especially those with any links or attachments found in them, as this can result in a system infection. You are advised to use official and trustworthy download channels.
Additionally, all products must be activated and updated with tools/functions provided by legitimate developers, since illegal activation ("cracking") tools and third party updaters are often employed to proliferate malware. To ensure device integrity and user safety, it is paramount to have reputable anti-virus/anti-spyware installed.
Keep this software updated, use it to perform regular system scans and to remove detected 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.

Example of a malicious Microsoft Excel document used to spread BitRAT malware:
Update January 4, 2023 - Newer and more versatile versions of BitRAT malware have been used to target the customers of an undisclosed Colombian bank. Cyber criminals have managed to obtain the clients' names, national IDs, addresses, payment history, salary data, phone numbers, email addresses, and other sensitive information through a breach of the bank's servers.
The stolen data has been observed being sold on the dark web and used in phishing email campaigns. Using this personal information, criminals can craft convincing fake emails that trick recipients into downloading and opening infectious Microsoft Excel documents, which use malicious macro commands to infect devices with BitRAT.

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.

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.
