The references do not describe a single cybersecurity incident or vulnerability. One article examines Anthropic’s lawsuit challenging a U.S. government decision to designate the company a national-security supply-chain risk and bar federal agencies and contractors from using its AI models after Anthropic refused to relax restrictions related to lethal autonomous warfare and mass surveillance. Another covers a separate court fight in which Perplexity AI won a temporary appellate stay of an injunction that would have blocked its Comet shopping agent from accessing Amazon accounts, after a judge found Amazon was likely to succeed on claims under the Computer Fraud and Abuse Act and California’s computer access law.
A third article is not about either dispute; it discusses Pentagon policy toward universities, arguing that Defense Secretary Pete Hegseth’s move to cut Defense Department academic ties with Harvard and other institutions could weaken U.S. competitiveness and force readiness. Because the materials concern distinct policy and legal controversies rather than one coherent cyber event, the set should not be treated as a unified incident report. It is also not fluff, since the content involves substantive legal and security-policy issues, including alleged unauthorized access to protected accounts and the use of national-security authorities against an AI vendor.

9 events from the most recent confirmed update back to the earliest known activity.
By 2026-04-21, U.S. officials were reportedly discussing allowing federal civilian agencies renewed access to Anthropic technology while keeping the company excluded from military procurement. The move followed the court’s injunction against the civilian-domain designation and highlighted ongoing uncertainty over federal AI supply-chain governance.
On 2026-04-09, a court denied Anthropic’s motion for a stay in its dispute with the government over continued restrictions on its AI technology during litigation. The ruling said the balance of equities favored the government because of national security and active military conflict concerns, while noting Anthropic had raised substantial issues warranting expedited review.
On 2026-03-27, U.S. District Judge Rita Lin granted Anthropic a preliminary injunction temporarily blocking the Trump administration from designating it a supply-chain risk and cutting off federal contracting access. The judge said the measures were likely unlawful and appeared punitive rather than grounded in legitimate national security concerns, while delaying the order for one week to allow the government to seek a stay.
In a federal court filing, Justice Department attorneys argued Anthropic’s ongoing control over model weights, guardrails, and tuning could let it alter or disable mission-critical defense AI systems, and said agencies must phase out its technology within 180 days.
Anthropic asked a federal court for a preliminary injunction against the Department of Defense, the White House, and other agencies, challenging the supply-chain-risk designation and the government-wide order to cease use of its technology.
The administration designated Anthropic a national security supply-chain risk and directed federal agencies to stop using its products after the company refused to remove Claude restrictions related to lethal autonomous warfare without human oversight and mass surveillance of Americans.
A federal appeals court temporarily stayed the district court order that would have blocked Perplexity from using its AI-powered shopping agent on Amazon while the case proceeds.
On March 9, U.S. District Judge Maxine Chesney granted Amazon a preliminary injunction, finding the company was likely to succeed on claims under the Computer Fraud and Abuse Act and California’s Comprehensive Computer Data Access and Fraud Act.
Amazon filed suit against Perplexity in November, alleging the Comet browser and its AI shopping agent accessed password-protected customer account areas without authorization, disguised automated activity as human browsing, and ignored repeated demands to stop.
