Bring out your dead: How agentic AI for cybersecurity helps you rid your cloud of forgotten, risky assets

Source Tenable Research

Description

This threat discussion focuses on the risk posed by forgotten or 'zombie' cloud infrastructure assets that remain in an environment but are no longer in production. These zombie assets increase the attack surface and cyber risk for organizations while also contributing to unnecessary cloud costs. The described solution, Tenable Hexa AI, uses agentic AI to identify and eliminate these forgotten cloud assets, thereby reducing risk and cost. There is no indication of an active exploit or vulnerability in this data, rather it highlights a security risk related to cloud asset management.

Impact

Zombie cloud assets that are no longer in production but remain active can expand the attack surface, potentially increasing cyber risk. They also contribute to unnecessary cloud expenditure. However, there is no evidence of active exploitation or malware infection associated with these assets in the provided information.

Defensive guidance

The vendor promotes the use of Tenable Hexa AI to automatically identify and remove forgotten cloud assets, thereby reducing risk and cost. Since this is a risk management approach rather than a vulnerability with a patch, organizations should consider implementing asset discovery and cleanup processes, potentially leveraging agentic AI tools as described.

Summary

The content describes the security risk associated with unmanaged or forgotten cloud infrastructure assets, termed 'zombie' assets, which can increase an organization's attack surface and operational costs. It promotes the use of agentic AI technology to detect and remove these assets, improving cloud security posture and cost efficiency. This is not a vulnerability or malware in the traditional sense but a risk management issue related to cloud asset lifecycle and visibility.
