What is InnfiRAT?

InnfiRAT is the name of a remote access or administration tool (RAT). Typically, software of this type is used to control connected computers remotely, however, in many cases, cyber criminals seek to trick users into installing RATs so they can use them to perform malicious actions. To avoid serious problems that can be caused with this software, we strongly recommend that you uninstall this RAT from your system immediately.

Typically, cyber criminals use RATs to steal personal information, which can then be used to generate revenue. Research shows that cyber criminals who proliferate InnfiRAT seek to steal cryptocurrency wallet information - they target Bitcoin, Litecoin, and possibly other wallets. Stolen wallets can be used to make fraudulent transactions: cyber criminals can empty cryptocurrency wallets by transferring funds to other wallets that are owned by them or other parties. Furthermore, InnfiRAT is capable of stealing cookies from browsers such as Chrome, Mozilla, Opera (and others), usernames and passwords stored on browsers, session data, and so on. These credentials can be used to steal email, banking, social networking, and other accounts. Stolen accounts might be used to make fraudulent purchases, transactions, send spam to other people, extort money from people who are in the victim's contact lists, and so on. Another feature available through InnfiRAT is screenshot grabbing. Cyber criminals use this feature to take screenshots of opened windows (system, browser, or others) any time they wish. The screenshots might contain personal details, which could be misused for malicious purposes. InnfiRAT sends all stolen data to its C&C (Command and Control) server, which cyber criminals use to perform malicious actions on the infected computer. For example, they could install additional malware such as ransomware. Ransomware is high-risk malware that usually encrypt files. In summary, the software locks files using strong encryption algorithms that cannot be decrypted without specific software. Typically, only cyber criminals have this software and they force victims to purchase it through ransom payments. Furthermore, InnfiRAT can be used to steal information such as victim's IP address, city, region, country, etc., and running processes. It can kill processes with names that contain strings such as "chrome", "firefox", "opera", "browser", and others. InnfiRAT is a powerful tool enabling cyber criminals to generate revenue by misusing data in various ways. To avoid data, financial loss, identity theft, having accounts stolen and/or computer infection with malware, and other problems, uninstall this RAT immediately.

There are many remote access tools (RATs) online, however, even legitimate ones can be used by cyber criminals who seek to generate revenue in malicious ways. Examples of other RATs include Gh0st, Poison Ivy, and NetWire. RATs can be used for various purposes and include differing features. In most cases, victims experience problems relating to privacy, browsing safety, finances, identity theft, and so on. If a RAT is installed on your system without your knowledge, remove it immediately.

How did InnfiRAT infiltrate my computer?

In most cases, cyber criminals proliferate malware (or legitimate software that could be used for malicious purposes) through spam campaigns, unofficial file or software download channels/tools, fake software updating and software 'cracking' (activation) tools. To proliferate malware through spam campaigns, they send emails to many users. These emails contain malicious attachments such as Microsoft Office documents, PDF documents, archive files (ZIP, RAR), executable files such as .exe or JavaScript files. When opened, the file causes installation of another malicious program. Examples of untrustworthy, dubious software download sources/channels are freeware download websites, free file hosting pages, Peer-to-Peer networks (torrent clients, eMule, and so on) and other such tools. Cyber criminals use them to disguise malicious files as legitimate. People who download files using these channels risk installation of malicious software if opened. Fake software updating tools (updaters) cause damage when they download malware rather than updating installed programs, or they exploit bugs/flaws of outdated software installed on the computer. People who use unofficial activation tools ('cracks') to activate software free of charge often end up infecting their computers with malware. Many of these tools install malware and do not activate any legitimate programs.

How to avoid installation of malware

Download, install, update software, and browse the internet carefully. Do not download files or programs using dubious sources. They should be downloaded from official and trustworthy websites. Update installed programs only through implemented functions or tools designed by official software developers. Note that unofficial activation tools often lead to installation of malware. Furthermore, it is illegal to use tools of this type. Attachments that are included in irrelevant emails should not be opened, especially if they are sent from unknown addresses. Cyber criminals disguise these emails as important, official, and so on. Avoid damage caused by malicious programs by regularly scanning the operating system with reputable anti-spyware or anti-virus software and remove detected threats immediately. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Manual malware removal is a complicated task - it is usually best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes 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:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware filename 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".

locate the malware file you want to remove

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.

searching for malware file on your computer

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 Malwarebytes for Windows.
