LoudMiner: Cross Platform Cryptocurrency Miner uses VST Software

An uncommon Linux cryptocurrency miner known as LoudMiner, is being distributed for macOS and Windows since August 2018. This cryptocurrency malware is using a clever cryptojacking technique to mine Monero.

LoudMiner uses virtualization software QEMU (Quick Emulator) on macOS and VirtualBox on Windows to mine Monero on a Tiny Core Linux virtual machine. It is pushed through pirated copies of Virtual Studio Technology (VST) like Propellerhead, Nexus, AutoTune, and others.

VST is an audio plug-in software interface that mixes software synthesizers and effects in digital audio workstations. Compromised machines are used to mine cryptocurrency and uses SCP (Secure File Copy) with embedded username and private SSH key to self-update.

Loud Miner malware targets audio applications that have high CPU usage making it difficult for the user to identify unusual CPU behavior.

How is LoudMiner Distributed?

At the time of writing LoudMiner is distributed via a single WordPress based website linked to 137 VST out of which 42 are for Windows and 95 are for macOS. However, instead of being hosted on WordPress based site they were hosted on 29 external servers that can be found on IoCs section.

What makes LoudMiner so clever and uncommon cyrptojacking malware?

Size of the app is what makes it impractical to analyze them. Also, site admins frequently update applications making it difficult to track the first version of the miner. Moreover, LoudMiner cryptojacking malware seems to target machines with high computing power, making detection difficult and mining cryptocurrency easy.

In addition to this, malware developers don’t need to compress Tiny Core Linux virtual machine and coinminer as VST hosts are quite large. Making victims install LoudMinder willingly as the pirated VST software comes bundled with virtualization software.
