Crypto Whale Loses $25.6M Again as Weekly Hacks Cross $37M

The week of August 9 to August 15 delivered another rough stretch for crypto security, with a repeat phishing drain of $25.6 million on an unidentified whale wallet, a $7.9 million cross-chain breach at Coinsbuy, a suspected 4 billion ONE mint on Harmony Protocol, a 200,000 XRP theft from the Coreum-XRPL Bridge, an unauthorized minting incident at Oraichain, and a pricing-logic flaw at USM Protocol pushing weekly confirmed damage past $37 million.

The stretch lands on top of an August that already opened with the fallout from the Coldcard firmware exploit, whose stolen bitcoin cache had climbed past $130 million by mid-month. It also extends the shift documented in CertiK’s H1 2026 report, which found Web3 lost more than $1.31 billion across 344 incidents in the first half, with wallet compromises and infrastructure breaches now the costliest attack surface.
