Debug.exe Crypto Miner
Debug.exe is the file name of what could potentially be a malicious cryptocurrency miner. Obviously, debug.exe may also be the name of a legitimate application, but if you find it always running on your system, without having started it manually, chances are you have been infected with crypto-mining malware.
It is nearly impossible to pinpoint which specific crypto miner you have on your system if you always see debug.exe running and active in your task manager. Different criminal organizations and outfits can use arbitrary names for their malware. The common thread here is that they will all attempt to rename their malicious payload to something that resembles a legitimate file.
There are instances of legitimate software which may have a file named debug.exe. The issue here is, this file will practically never execute if the software did not crash and you manually started its debugger module. If you simply see a process called debug.exe always running in your system's task manager, chances are this is a malicious crypto miner.
There are many different ways similar malware may land on your system. Those may include malicious spam email campaigns with attachments that are either the payload itself or documents that link to it and automatically download it from its location online.
There are also numerous known instances of this type of malware being distributed through torrents that allegedly distribute pirated software. Very often, instead of a cracked executable, users end up starting malicious payloads on their systems, thinking they are getting free software.
Being extra careful when dealing with any emails that have attached files and never using torrents that are used to distribute illegal content, whether this is media or applications, is a great first step towards steering clear of crypto miners similar to debug.exe, no matter which specific miner malware is using this specific filename to hide behind.
