How Did RubyMiner Infect My PC?
There are more than one method by whch RubyMiner may propagate on your computer system. The virus often uses malicous files that are masked as legitimate and it may introduce them to you either passively or actively. The passive methods are if the malware uploads the malicious files on a suspicious website as the files you may be looking for to download. Such files are often:
- Fake game patches.
- Fake cracks.
- Torrent files that are actually executable files.
- Fake setups of software or games.
- Fake license activation software.
In addition to this, the cyber-criminals who are behind RubyMiner malware may also infect your computer via other methods that are more active, like sending spam messages containing short URL’s that may lead your computer to an unsafe website, causing the infection via a drive-by download or a malicious script. In addition to this, the virus may also be sent to you in the form of a fake document which only pretends to be legitimate. Such files and documents are usually accompanied by deceitful messages, like the example malicious spam e-mail below shows:
RubyMiner – Capability and Activities
When an infection with RubyMiner has taken place on your computer, the malware begins to drop it’s files on your computer. The main folders on which the files of RubyMiner may be dropped are believed to be the following:
Once RubyMiner has set it’s files to be dropped on your PC, the virus may activate them and begin performing various malicious activities on your computer. Since it is malware, RubyMiner may extract the following information from your computer system:
- Your network information.
- Your saved passwords and logins.
- Log your keystrokes.
- Update itself.
- Copy itself multiple times to make the removal of files more difficult.
- Download other malware on your computer.
The main activity of RubyMiner however is to run a miner on your computer which begins to utilize over 90% of both your GPU and CPU (Video Card and Central Processor). These activities may result in the malware being able to generate cryptocurrency tokens and add them to the cryptocurrency wallet of the cyber-criminal who is behind the infection with RubyMiner. This usually happens by connecting your computer to a mining pool (see image below) of many computers, which easifies the mining process. The more computers, the cyber-criminal has infected and linked to his wallet, the faster he will generate cryptocurrency tokens at your PC’s expence. In addition to this, since the malware aims to stay for longer periods of time on your computer system, the virus may begin to break down your components, if it stays for longer periods of time. This is because the mining process uses a lot of the CPU and GPU’s arithmetica-logial calculating power and this results in a lot of side heat temperature to be generated in the process.
