Large Scale Monero Cryptocurrency Mining Operation using XMRig
Real in depth read on hackers Mining Monero - over 30 million machines.
"Summary
Palo Alto Networks Unit 42 has observed a large-scale cryptocurrency mining operation that has been active for over 4 months. The operation attempts to mine the Monero cryptocurrency using the open-source XMRig utility.
Based on publicly available telemetry data via bitly, we are able to estimate that the number of victims affected by this operation is roughly around 15 million people worldwide. This same telemetry provides insights into the most heavily targeted areas involving this campaign, which impacts southeast Asia, northern Africa, and South America the most.
However, it’s important to note that the actual number of victims is likely much higher because less than half of the samples we identified in this campaign leverage bitly. If we postulate that the bitly telemetry is typical for this operation, we can extrapolate to speculate that as many as 30 million people have been affected by this operation. While the actual number could be more or less, this does serve to give an idea of the possible size and scope of this large scale operation.
The attackers make heavy use of VBS files and use various online URL shortening services to install and run the XMRig payload. Additionally, the attackers mask the wallets used by leveraging XMRig proxy services on the hosts to which they are connected."
