Securonix Threat Research Report: Detecting Persistent Cloud Infrastructure/Hadoop/YARN Attacks Using Security Analytics: Moanacroner, XBash
In recent months, we have been observing an increase in the number of automated attacks targeting exposed cloud infrastructure/Hadoop/YARN instances. Some of the attacks we have been seeing – for example, Moanacroner (a variant of Sustes) – are fairly trivial, targeted single-vector/single-platform attacks where the focus is mainly on cryptomining.
Some attacks, however, are multi-vector/multi-platform threats where multiple functionalities – including cryptomining, ransomware, and botnet/worms for both Linux and Windows – are combined as part of the same malicious threat (for example, XBash).
The Securonix Threat Research Team has been actively investigating and closely monitoring these persistent malicious attacks impacting exposed cloud infrastructure in order to help our customers prevent, detect, and mitigate/respond to the attacks. Inside is a summary of what we currently know, and our recommendations for possible mitigations and Securonix predictive indicators that can be used to detect such attacks.Read More
