How to remove NetWeirdRC RAT from Mac computers

What is NetWeirdRC?

NetWeirdRC is a Remote Access Trojan (RAT), which works on macOS X 10.6 (and later), Windows, Linux, and Solaris operating systems. Typically, cyber criminals attempt to trick users into installing RATs so that they can gain control over computers remotely and perform various actions (install other malware, steal sensitive information, files, etc.). Commonly, RATs do not appear in the list of active programs and running processes, and therefore they can be installed on the computer for an extended period of time without being detected.

NetWeirdRC remote access trojan

Quite often RATs such as NetWeirdRC are capable of logging keystrokes - they can record keyboard input (keys pressed on the keyboard). Therefore, cyber criminals can use RATs to steal entered login credentials (emails, usernames, passwords), credit card details and other sensitive, personal information that victims type using the keyboard. RATs are also capable of accessing the computer camera and/or microphone, personal documents, photos and other files, and data stored on the system. Furthermore, they are often used to infect computers with additional malware or other rogue software (e.g., ransomware, Trojans, cryptocurrency miners). Therefore, users who have computers infected NetWeirdRC may suffer monetary, data loss, lose access to various personal accounts, become victims of identity theft, and/or experience other serious issues relating to online privacy and browsing safety. Note that stolen accounts could be misused to spread NetWeirdRC (or other malware) onto other computers. If there is any reason to suspect that NetWeirdRC is installed on the operating system, eliminate it immediately.

More examples of RATs are Proton, HoudRat and WellMess. Typically, software of this type is used by cyber criminals who attempt to generate as much revenue as possible by using it to steal sensitive information, install other malware or even spread it on other computers. Examples of how cyber criminals attempt to trick users into installing this software onto their computers are described in the next paragraph.

How did malware install on my computer?

Frequently, users are tricked into infecting their computers with malware through malspam campaigns (emails), fake software updating tools, dubious software, file download sources, Trojans and unofficial activation ('cracking') tools. Through malspam campaigns, users might be tricked into opening a malicious file in a received email (or a file downloaded via malicious link). Some examples of files that cyber criminals attach to their emails are malicious Microsoft Office or PDF documents, archive files such as ZIP, RAR, executable files (.exe) and JavaScript files. Fake software updaters can also cause installation of malware. Commonly, these tools infect computers by exploiting flaws/bugs of outdated programs that are installed on the computer, or installing malicious software rather than updates/fixes for the installed software. To install malware through dubious download sources, it is necessary to download a malicious file and execute it. Cyber criminals commonly disguise these files as regular and legitimate. Examples of dubious download channels and sources are Peer-to-peer networks (e.g., torrent clients, eMule), third party downloaders, freeware download, and free file hosting web pages. Third party installers can also be designed to install malware  A Trojan is a type of malware program that can cause damage, but only when it is installed on the computer. Once installed, Trojans can cause chain infections by installing other malware. Software 'cracking' (unofficial and illegal) activation tools are programs that supposedly activate licensed software free of charge, however, they often install malicious software instead.

How to avoid installation of malware

Installed programs must be updated and activated with implemented functions or tools that are provided by official developers. Unofficial, third party tools are often designed to install malicious software. Furthermore, it is illegal to activate licensed programs with unofficial tools. Software and files should be downloaded only from official websites and through direct links. Other sources/channels mentioned above should not be used. The same applies to third party installers. Attachments and/or links in irrelevant emails that are received from suspicious, unknown addresses should not be opened - the emails are often sent by cyber criminals who attempt to trick recipients into executing malicious files designed to infect operating systems with malware. They usually disguise their emails as important and official. Regularly scan your computer for threats with reputable antivirus or anti-spyware software. You are strongly advised to have one installed and keep it up to date. If your computer is already infected with malware or unwanted applications, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
