๐ŸšจSlowMist TI Alert๐Ÿšจ ๐Ÿ’ธ @SetProtocol Loss: ๏ฝž9.6K USD ๐Ÿ” Root Cause: Index Coop `ExchangeIssuance.issueSetForExactToken` trusted arbitrary SetToken state without locking. The function read components and units for quoting, but allowed a malicious manager pre-issue hook to inflate `positionMultiplier` via NAV `issue`/`redeem` with a fake valuation. `BasicIssuanceModule.issue` then read inflated real units from `ExchangeIssuance` via `transferFrom`, causing TOCTOU-based asset drain. ๐Ÿ“Œ Attacker: 0x0736930ae35eafefa789f11edf41d7b799e7c99d ๐Ÿ“Œ Victim: 0xc8c85a3b4d03fb3451e7248ff94f780c92f884fd (ExchangeIssuance) ๐Ÿ“Œ Malicious SetToken: 0xf7c2d0a2bf81bf803ed6e1d97c89fe3b30b06948 ๐Ÿ“Œ Malicious Manager/Hook: 0x8f449d85f728c1dd6596880ba28a0b80b6a26c58 ๐Ÿ“Œ Malicious Valuer: 0x388a3da33825e1f44ac71b8fd543523cdf994802 โš ๏ธ Impact: ExchangeIssuance lost real assets after attacker issued BHSET with 0.05 WETH, then abused hook to inflate component units ~93.66x, allowing excessive `transferFrom` during issue.
