How to remove LoudMiner from Mac?

What is LoudMiner?

LoudMiner is a cryptocurrency miner based on XMRig (another miner) and designed to mine Monero cryptocurrency. LoudMiner is cross-platform software, and thus can run on different operating systems such as MacOS, Linux, and Windows. It is distributed by bundling it with set-ups of pirated (cracked) copies of VST (Virtual Studio Technology) software. Cyber criminals who proliferate LoudMiner attempt to trick people into installing this rogue software so they can misuse their computers (computer resources) to mine cryptocurrency. If LoudMiner miner is installed on your operating system, remove it immediately.

setup of cracked VST identified as a threat

When a cryptocurrency miner such as LoudMiner is installed, it uses computer resources such as the CPU (central processing unit) and GPU (graphics processing unit) to solve mathematical problems and mine cryptocurrency. As mentioned above, LoudMiner is based on XMRig, which utilizes the system CPU. The mining process in general causes high CPU (or/and GPU) usage, even up to 100%. Therefore, affected computers operate much slower or do not respond at all. The cryptocurrency mining process might cause unexpected shutdowns, which can lead to data loss or cause hardware overheating. Computers with miners installed on them consume more electricity, and thus users of these computers receive higher electricity bills. Only the cyber criminals who trick people into installing these programs benefit from this process. They use computers of unsuspecting people to mine cryptocurrency and generate revenue. LoudMiner runs on systems through virtualization software. It uses QEMU on macOS and Virtual Box on Windows. When installed, this software can be found running on systems as a process called "qemu-system-x86_64", "tools-service" or "System-monitor.daemon", "VirtualDJ" (on MacOS) and "VmServiceControl.exe" on Windows. Note that the process name might vary and criminals can also use names of genuine/legitimate processes as a deception. Cyber criminals disguise virtualization software (virtual machines) as programs such as Propellerhead Reason, Ableton Live, Sylenth1, Nexus, Reaktor 6, Kontakt Native Instruments, AutoTune, and many others. So, if there is a cracked (pirated) version of a VST software installed on a computer, it is very likely that this was also used proliferate the LoudMiner cryptocurrency miner.

There are various cryptocurrency miners online, and often they are legitimate, however, many cyber criminals use these programs to generate revenue by misusing the computers of other people. Some examples of other cryptominers include Plurox, Digmine, and NRSMiner. If your computer is infected with a program of this type (and was installed unintentionally), removed it as soon as possible.

How did potentially unwanted applications install on my computer?

Cyber criminals distribute LoudMiner through set-ups of pirated VST software. In this case, it is bundled into set-ups of cracked software relating to audio production. In many cases, unwanted programs are bundled into setups of other software that people wish to download and install, however, cryptocurrency miners (or other unwanted programs, such as malware) can also be distributed in other ways. Typically, cyber criminals proliferate malicious programs through spam campaigns, trojans, fake software updaters and untrustworthy software download sources. They use spam email campaigns by sending emails that contain malicious attachments. These are usually Microsoft Office documents, PDF files, executable files, archive files such as ZIP, RAR and so on. To infect systems, these attachments must first be opened. They then cause download and installation of a malicious program. Cyber criminals also infect computers with malware through trojans: malicious programs that proliferate other infections and cause chain infections. To cause any damage, however, they must already be installed. Fake software update tools are used to proliferate computer infections by downloading and installing malicious programs rather than updating (or fixing) installed programs, or by exploiting outdated software bugs/flaws. Software cracking tools operate in a similar manner: people use them to bypass activation of licensed software, however, these tools are often used by cyber criminals to install malware rather than cracking any software or operating system. Untrustworthy software download sources such as freeware download websites, free file hosting websites, peer-to-peer networks such as torrent clients, eMule and other such tools, third party downloaders can be used to present malicious software as legitimate. In this way, cyber criminals trick people into downloading and installing infections such as LoudMiner.

How to avoid installation of potentially unwanted applications?

Do not download programs from dubious sources such as Peer-to-Peer networks (torrent clients, eMule, etc.), unofficial pages and so on. The only safe way to download software is using official websites and direct download links. All programs should be downloaded and installed properly. Check any additional settings in the set-ups and dismiss offers to download or install unwanted bundled programs. Be careful opening attachments or links that are presented in e-mails received from unknown, suspicious, or dubious addresses. If an email is irrelevant, ignore it and do not open anything. Do not use software cracking tools or use cracked software. This is illegal and often leads to computer infections. Installed programs should be updated properly using tools or functions provided by official developers. Finally, have reputable anti-spyware or anti-virus software installed to keep the computer safe from infection. These tools usually detect and remove them before any further damage can be done. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
