Arbitrum SEA attacks drain $153,000

- Security researchers flagged a series of "SEA attacks" on Arbitrum that exploited transaction flows and resulted in roughly $153,000 drained from on‑chain activity. - The reported loss is small relative to overall Arbitrum TVL but notable as a pattern of targeted adversarial activity on L2 sequencer flows. - The episode reinforces that L2 investability depends on operational security and that small exploits can dent token sentiment during risk‑off markets.
