Rocke'in the Net Flow

Summary: Unit 42 analyzed NetFlow data from December 2018 to June 16, 2019 and found that 28.1% of the cloud environments it surveyed had at least one fully established connection to a known Rocke command-and-control domain, with 20% of organizations maintaining hourly heartbeats consistent with Rocke TTPs. The China-based cryptomining group, also known as the Iron Group and SystemTen, has released a new tool called Godlua that can act as an agent for scripted operations including denial of service, network proxying, and two shell capabilities.

What you should know: Nearly three in ten cloud environments surveyed were talking to Rocke infrastructure, and some did so almost daily for months without apparent detection - a hardcoded IP alone, 104.238.151[.]101, accounted for 411 unique connections across four monitored organizations.
