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.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
