BitSight, a cybersecurity company, has revealed that a sophisticated botnet called MyloBot has affected thousands of systems across the globe.
Most of the compromised systems are located in India, the United States, Indonesia, and Iran.
BitSight has also found that MyloBot’s infrastructure is linked to a residential proxy service named BHProxies, implying that the compromised machines are being used by the latter.
The botnet was initially observed in 2017 and was first documented in 2018. It is known for its anti-analysis methods and its ability to act as a downloader.
MyloBot has the potential to download any other type of malware that the attacker wants. It also waits for 14 days before attempting to contact the command-and-control (C2) server to avoid detection.
MyloBot receives instructions from C2 and transforms the infected computer into a proxy. The malware has been observed sending extortion emails from hacked endpoints as part of a financially motivated campaign.
MyloBot continues to evolve over time, and BitSight has been sinkholing the botnet since November 2018.
