Switchboard, an oracle provider, said contributors halted its deployments on Aptos, Sui, IOTA, and Movement after reports of a potential compromise in its Move-language implementations. [^1]

Full Sail, a decentralized exchange on the Sui network, announced on September 1, 2026, that it is winding down operations after an attacker drained roughly $91,000 from three of its vaults on August 29. [^2]

At least three applications reported losses, freezes, or precautionary access restrictions following the Switchboard incident. [^3]

Full Sail confirmed that its vaults lost funds and said deposits and withdrawals would remain paused until oracle integrity was restored and verified. [^4]

Virtue, an IOTA credit protocol, said an attacker gained control of the signing keys used by all 14 oracles on Switchboard's IOTA mainnet queue and pushed IOTA's reported price to $10 million. [^5]

Full Sail paused deposits and withdrawals after confirming the incident on August 29 and committed to returning funds to affected users while absorbing the shortfall. [^6]

Full Sail stated that the attack was not an admin key compromise but involved direct liquidity pool positions, allowing the attacker to deposit funds and withdraw more than the deposit value once prices were restored. [^7]

The attacker exploited Switchboard production code that governs who can sign oracle price updates, adding a key they controlled to a live oracle to push prices roughly 100 times below market. [^8]
