Short bio

Backdoor.BitCoinMiner is  Malwarebytes’ detection name for a few backdoors that install crypto-currency miners on the affected machine without the users’ consent.


Crypto-currency miners use a lot of resources to optimize the earning of crypto-coins, so users may experience slow computers.

Type and source of infection

The dropping or downloading of a backdoor is often the second stage in an attack, where the first stage is the infiltration of the Trojan dropper or downloader, and the final stage is gaining full control of the affected system. In many cases, a backdoor is a payload as the attacker can build out his control once it is functioning. Infections detected as Backdoor.BitCoinMiner are usually downloaded by the users themselves, but under false pretences.


Besides slowing down your machine, running at peek level for long times may cause damage to your machine and raise electricity bills.
