Coinhive Miner – How Does It Infect

To infect computers, the Coinhive Trojan uses methods no different than what any other crypto miner would employ. The malware may infect your Mac as a result of you having to download a suspicious installer, license activation software, fake portable program, malicious Microsoft Office or other documents and simply starting them. These files may come uploaded on Torrent sites or by being set as the download you are looking for on suspicious and compromised WordPress websites.

Another very widespread method by which the Coinhive Miner may spread onto your Mac is via e-mail. Usually, viruses, like the Coinhive miner Trojan may be coming as an e-mail attachment tht poses as a legitimate document of great improtance and the end goal of such malspam e-mails is to convince you, the vicitm, to open the attachment. Usually the files that are most widely used to mask the malicious origin of this virus are:

  • Receipt of a purchase.
  • Invoice.
  • Document from your company.
  • Document from a big company.
  • Document from a bank.
  • Report of a problem with your account on a website you may be registered in.

These messages are masked in a very clever way. Below you can see an example of such malicious e-mail:

Coinhive Miner Trojan – What Does It Do

When the Coinhive Miner trojan infects your mac, the virus may immediately drop it’s payload on it. The payload may consist of the main infection file of the virus and other sub-infection files. Once dropped the miner may request your permissions to activate it while being masked as a legitimate program or a document.

Once an infection is triggered, the Coinhive Miner Trojan may run a “com” process in your Mac’s activity monitor and this process may be hidden or may start to appear. Once this is done, the miner may overtake a significant percentage of your CPU and GPU (Video Card and Central Processor) in order to perform the calculation of hashes that are needed to miner cryptocurrencies. You may immediately notice a decrease of your Mac’s performance as a result of the Coinhive Miner being active and your Mac may even freeze.

The malicious executable file, that belongs to the Coinhive Miner Trojan may establish a connection to the Coinhive network and as a result of that may begin the minig operation on your Mac by listing its IP address in the mining pool. Once a reward for the mining is accredited, it immediately goes to the wallets of the cyber-crimilas and the more Macs and computers they infect, the more Monero coins they are able to mine, while taking illegal advantage of your machine, without your permission or approval.

And this is not the only risk, associated with the Coinhive Miner Trojan, because it may also use spyware elements to obtain information from your Mac, such as:

  • Your financial credentials.
  • Your network and system details.
  • Your passwords.

And furthermore, since the Coinhive miner virus is also a Trojan, it may perform other activities as well, like;

  • Install other cryptocurrency miners.
  • Update itself to remain hidden for longer periods of time on your Mac.
  • Collect the keys you type on your Mac.
  • Collect your IP address, network, antivirus and other information.
