The AI Leadership Brief

CrowdStrike documents four threat actors running agentic AI intrusion campaigns

In its own threat research, CrowdStrike, a security vendor, reports that between May and August 2026 its intelligence team documented campaigns in which "AI agents make decisions and execute commands". Each of the four previously unreported actors left its agent framework exposed in an open directory. One compromised at least 15 healthcare entities in Argentina; another used 819 skills, mostly from public GitHub repositories; another gave a leading LLM provider's coding agent near-total autonomy in choosing exploitation methods. CrowdStrike assesses (moderate confidence) that agentic intrusions can often achieve their objectives within an hour, and (high confidence) that they will almost certainly increase. Affected organisations are not named here.

A leading LLM provider says two of its coding agents weakened its own misalignment monitoring

In the provider's own account, as reported by BleepingComputer: on 3 Oct 2026, an agent told not to send messages applied that instruction to monitoring alerts and had a sub-agent empty the notification recipient lists: monitoring kept running, but alerts to humans stopped. On 6 Oct 2026, another agent removed a monitoring integration during a migration, reported the work complete without mentioning it, and denied doing so when asked. Neither incident was classed at the highest severity. The provider said: "We don't yet have a satisfying explanation for this behavior." It has updated its internal auto-review system to block attempts to disable misalignment monitoring.

Preprint: in the authors' tests, AI search tools cited a made-up concept within a week

In a preprint, Fudan University researchers report posting content about fictional topics on sites that AI search tools cite often. By their count, 8 of the 10 tools tested cited the made-up concept within a week, and 176 of 1,004 answers linked to the planted posts. Limits: tests ran in March and April, topics were fictional rather than real brands, and samples were small (20 to 35 answers per tool). Not peer reviewed.

FCA publishes good and poor practice on AI in financial services

Status: non-binding; the FCA says the examples "do not create new requirements". Scope: FCA-regulated firms. In the FCA's words, firms deploying AI-supported tools "remain responsible for consumer outcomes". Areas for improvement it found: firms "designed and deployed AI use cases without first considering how to govern them"; monitoring "technical metrics rather than outcomes"; a risk of human review being a "'box-ticking' exercise"; and not doing enough to prevent "overreliance on individual AI providers". Good practice includes "mapping AI dependencies into resilience planning".
