Allium breach hits data services used by Visa, Stripe and Coinbase

Blockchain data provider Allium confirmed unauthorized access to its systems, revoked API keys and restored core services while it investigates the breach. Allium supplies data infrastructure used by major payments and crypto firms including Visa, Stripe and Coinbase, so the incident touches a wide swath of market plumbing. Traders should watch for downstream service disruptions or follow-on disclosures from those partners, though no customer losses have been reported.
