RubyMiner malware aims to exploit users' computer resources to mine cryptocurrency. Currently, it particularly targets to generate Monero. Unfortunately, such stealth actions might lead to a significant deterioration of your computer's performance. In fact, you can notice slowdowns and reduced latency[1]

Ruby Miner usually travels as supposedly legitimate software or its crack on file-sharing websites. Once this malware infiltrates the system, it starts to exploit approximately 90% of your computer's CPU and GPU to mine digital currency intensively. Later, the generated crypto tokens are transmitted to the hacker's wallet.

Be aware that criminals are able to get more profits if they connect computers with RubyMiner together. It means that they can increase the necessary computing power to mine cryptocurrency faster. Thus, making more crypto tokens by exploiting other computers without their owners' knowledge. 

Likewise, the hackers aim to protect the malware from elimination and make sure that it stays on the computer for an extended period of time. Unfortunately, it might be disguised as legitimate system processes in the Task Manager to hide its presence. Therefore, if you notice that a task is overusing CPU[2], have in mind that your computer might be infected with RubyMiner virus.

Furthermore, mining cryptocurrency is not the only malicious activity this malware might perform. If your system is infected with RubyMiner malware, it can also do the following:

  • Steal sensitive data, including usernames and passwords;
  • Track your keystrokes and log them;
  • Download add-ons to update its malicious activity;
  • Infiltrate other dangerous computer hazards.

Thus, if you have any doubts about your computer's security, immediately run a full system scan using a professional anti-malware software. You can get Reimage to help you check your PC for various infections, including cryptocurrency miners. It will also remove RubyMiner automatically if detected.

However, we kindly ask you not to try to complete RubyMiner removal manually. BedyNet.ru[3] experts say that it might replicate itself to different directories and trick you into terminating legitimate computer processes. Always rely on robust antivirus if you deal with cryptocurrency miners.

Peer-to-peer (P2P) networks are the primary source of malware

Since P2P networks allow users to directly search and download files from the computers of others, criminals use them to distribute malware or even more dangerous infections. However, the malicious programs are re-named to look innocent and useful to trick inexperienced computer users infecting their systems.

Hackers design the malware to resemble software or file which is highly demanded online to reach the maximum number of infected computers. Thus, most of the times malware disguise as legitimate programs, like Photoshop, etc. Additionally, they can design the malware to look like a software crack as well.

Therefore, if you want to protect your system against cryptocurrency miners and other high-risk computer infections, avoid downloading programs, video and audio files or music illegally. Instead, use only official websites to get the software you need. Otherwise, you risk your computer's security.

Learn how to detect and uninstall RubyMiner malware

As we have already mentioned, RubyMiner virus has various capabilities which allow it to hide and protect itself from elimination. Therefore, if you have noticed that your computer's performance has significantly decreased, you should first check the Task Manager for excessive CPU utilization. 

In case you have detected a suspicious process which is overusing your computing power, immediately end it. Later, you should employ a robust antivirus to remove RubyMiner from your system.
