The type of attack initiated by Jacob in the above scenario is a cross-container attack. A cross-container attack is a type of attack that targets container technology and exploits the shared resources and network connections between containers. A cross-container attack can compromise the security and availability of multiple containers and the underlying host by performing actions such as stealing data, executing commands, consuming resources, or spreading malware. A cross-container attack can be launched by an external attacker who gains access to a container through a network vulnerability, or by a malicious insider who runs a rogue container on the same host or cluster.A cross-container attack can be prevented or mitigated by implementing security best practices for container technology, such as isolating containers, limiting privileges, enforcing policies, scanning images, and monitoring network traffic123.References:
