Silentbob, a threat actor linked to the infamous cryptojacking group known as TeamTNT, has been identified as a significant cybersecurity concern. Silentbob has been involved in an aggressive cloud campaign, infecting as many as 196 hosts. The activity is named after an AnonDNS domain set up by the attacker and is noted for its use of tactics, techniques, and procedures (TTPs) that overlap with those of TeamTNT. The Silentbob campaign was first detected during an attack on a Jupyter honeypot run by Aqua Security. Further investigation led to the examination of a container image and Docker Hub account, revealing the nature of Silentbob's operations. The threat actor deploys an aggressive cloud worm designed to target exposed JupyterLab and Docker APIs. Once deployed, this worm facilitates the deployment of Tsunami malware, hijacks cloud credentials and resources, and enables further infestation of the worm. Aqua Security's report titled "Anatomy of Silentbob’s Cloud Attack" provides a detailed overview of the preliminary stages of this botnet campaign aimed at cloud-native environments. Notably, Silentbob's cloud attack delivers a cryptominer, adding to the list of threats posed by this actor. This resurgence of TeamTNT targeting Kubernetes clusters through the Silentbob campaign underscores the growing threat to cloud environments and the need for robust cybersecurity measures.
