Nearly 8,000 Solana wallets were drained for at least $6 million worth of assets, including native SOL tokens and SPL tokens like USDC. The attack went on for nearly a day before Solana identified the likely cause: private keys that were exposed to an application monitoring service used by the crypto wallet Slope. Both Solana and Slope were vague about further details but explained that they were continuing to investigate.

Total loss estimated at $6,000,000.
