## What to check

- Applies to: Not tied to a specific actor, malware or CVE, only to the sectors it covers, so it may be general reporting. Check the source before acting on it. Whether it concerns you is not assessed.

CISA and the Canadian Centre for Cyber Security, along with partners, published joint guidance titled 'Managing AI Token Consumption for Operational Resilience.' The document addresses operational risks tied to organizations' growing reliance on third-party 'super intelligence' (SI) / AI services that use token-based billing and usage models. It warns that unmanaged token consumption can lead to unpredictable costs, degraded performance, reduced service availability, token exhaustion, and denial-of-tokens or denial-of-wallet attacks, where an adversary or runaway process drives excessive token usage to exhaust budgets or rate limits.

The guidance provides practical recommendations for critical infrastructure owners, operators, and cyber defenders: prioritizing token allocation for mission-critical functions, designing efficient workflows, improving prompting practices, leveraging caching and reusable context, optimizing data before submission to AI services, and monitoring token consumption over time. It also recommends organizations map their dependencies on SI service providers and plan for degraded or unavailable AI services during outages, incidents, or periods of high demand, while maintaining human oversight and standard cybersecurity fundamentals in AI-enabled defense workflows.

This is best-practice operational guidance rather than reporting on an active campaign or vulnerability. There are no known exploited vulnerabilities, named threat actors, or malware associated with this release; it is preventive and risk-management guidance for organizations increasingly dependent on token-metered AI/SI services.
