Notorious Malware CyberGang Goes All in on Unsecured Kubernetes Clusters. TeamTNT, a notorious cybergang known for its container-based attacks on cloud infrastructure, has found Kubernetes to be a useful tool in its efforts to mine Monero cryptocurrency from other people’s servers.
TeamTNT, a notorious cybergang known for its container-based attacks on cloud infrastructure, has found Kubernetes to be a useful tool in its efforts to mine Monero cryptocurrency from other people’s servers, according to a new report from Unit 42, the research arm of Palo Alto Networks.
On their own four-node “Honeypot” Kubernetes cluster, the researchers watched the attackers roll out a sophisticated attack that commandeered their containers using common Linux and cloud native tools. The actions were part of a larger botnet, dubbed “Hildegard,” whose size is still undetermined.
“From another ongoing research, we do know that there are at least 2,000 misconfigured Kubernetes clusters,” noted Jay Chen, a Unit 42 senior cloud researcher. These misconfigured systems can be easily found by searching Shodan Internet of Things search engine, and the by search capabilities offered by security vendor Censys. “These misconfigured Kubernetes are all potential targets.”
