CoinImp Coin Miner – How Did I Get Infected
First of all, you have to understand that the CoinImp Coin Miner is not a file that is on your hard drive. The malware is actually a script which is taking advantage of your Web Browser and this includes all commonly used web browsers, like:
- Mozilla Firefox.
- Google Chrome.
- Microsoft Edge.
- Internet Explorer.
- Safari (Yes, It can happen on MacBooks too).
But do not let the fact that CoinImp is a script on websites fool you that your computer is actually safe – it may just be not. This is because the sole purpose of CoinImp is the following (according to their site):
CoinImp Coin Miner – How Does It Work?
Once you have been connected to the mining pool of CoinImp, the script begins to use your web browser as a way to tap into your GPU and CPU. You may immediately notice this as your web browser may start to cause your computer to slow down and freeze. This is because the CoinImp miner is already taking up a lot of your CPU and GPU’s resources, as we have detected it to do in the screenshot underneath:
This is a clever strategy for the CoinImp cryptocurrency miner to do, because the malware uses the legitimate web browser’s .exe file, which is not blocked by any antivirus program – really smart.
In reality, what the CoinImp miner does by taking over your CPU and GPU’s power is to establish an active connection with a so-called cryptocurrency mining pool. Such connection lists your computer on the behalf of one wallet, tied to all the affected computers – the hacker’s Monero wallet. From there, things become clearer – the crypto-miner uses the power of many affected computers to perform the so-called hashing algorithm. Such mining pools often work as many miners are connected to one mining pool and they are rewarded based on how much mining power they have. This means that the more computers are affected and linked to one miner wallet (the hacker’s), the more money they will make on unsuspecting users’ processor and video card resources.
And this is not the only danger of having CoinImp on your computer. If the miner is installed as a result of a Trojan horse running on your computer and connecting it by force to the mining pool, you may not notice the virus as a web browser process, but rather a shady .exe running active on your Windows Task Manager. And if malware has indeed infected your PC, there is not a symptom that gives the malware away, only the miner. And this is where the actual danger may be, because besides mining for Monero, a CoinImp miner Trojan may also do more damage than you can possibly imagine:
- Infect other computers on your network.
- Download other malware on your PC.
- Update itself to stay undetected.
- Log the keystrokes you type on your keyboard.
- Take screenshots of your screen.
- Steal files, passwords and financial details from your PC.
This is more than enough for you to take actions towards securing your computer in case it has been affected by the CoinImp miner malware.
