Haruko, a London-based crypto technology provider for institutional clients, was hit by a targeted cyberattack that affected 15 customers and exposed read-only exchange API details and trading data. Some smaller hedge-fund clients with weaker security controls may have lost a small amount of funds, while Haruko said it has fixed the vulnerability and refreshed server-side secrets.

Trezor says nearly 14,000 customers had personal information exposed after unauthorized access at fulfillment partner ShipMonk. The hardware wallet maker says its own systems and devices remain secure, but affected users face elevated phishing risks.
