In this video I take a look at a cryptojacking attack against a Kubernetes honeypot.
The attackers were surprisingly quick to discover this unsecured Kubernetes deployment and use it to mine Monero for them.
The analyzed capture files can be downloaded fromhttps://share.netresec.com/s/S5ZG2cDKB9AbqwS?path=%2Fk3s-443
This PCAP dataset was created by Noah Spahn, Nils Hanke, Thorsten Holz, Chris Kruegel, and Giovanni Vigna as part of their research for their Container Orchestration Honeypot: Observing Attacks in the Wild paper.
The capture files named "proxy-", such as the analyzed proxy-220404-162837.pcap, were generated by PolarProxy and contain the decrypted Kubernetes API traffic to the master node.
This traffic was actually TLS encrypted, but since PolarProxy was used as a TLS interception proxy we can see the Kubernetes API traffic in decrypted form.

In this video I analyze a pcap file with network traffic from Cobalt Strike Beacon using CapLoader .
The pcap file and Cobalt Strike malware config can be downloaded from Recorded Future's Triage sandbox .
Cobalt Strike Beacon configs can also be extracted locally with help of Didier Stevens' 1768.py or Fox-IT's dissect.cobaltstrike .
