Ostium Attack Post-mortem: Off-chain Oracle Permissions Stolen, Forged BTC Price to Arbitrage 23.75 Million USDC

According to Ostium's official report, the core of this attack lies in the compromise of the off-chain price reporting system permissions, unrelated to smart contract vulnerabilities. After obtaining off-chain authorization, the attacker utilized the protocol's registered legitimate forwarding paths to submit forged prices ($5,000 and $60,000) to the BTC-USD market, atomically completing an open-close position arbitrage cycle within the same transaction. Starting with 100 USDC and rolling to amplify the scale across 8 transactions, they extracted 23.75 million USDC from the OLP vault within 5 minutes until the vault circuit breaker mechanism was triggered. The root cause lies in the off-chain infrastructure lacking a multi-party approval mechanism equivalent to on-chain multi-signature, creating a single-point permission vulnerability. The stolen funds have been converted to ETH and mixed via Tornado Cash; tracking efforts are still ongoing.

Loss of 23,752,746 USDC: Ostium Price Data Attacked

Odaily News: Headline: "Loss of 23.75 Million USDC: Ostium Price Data Attacked". According to Ostium's monitoring, Ostium has released an update on the security incident. Its liquidity provider treasury was attacked on July 15, resulting in a loss of 23,752,746 USDC. Preliminary investigations indicate that the attacker compromised the off-chain infrastructure that supplies price data to the protocol, submitting disguised, fraudulent price reports. By rapidly opening and closing multiple large positions, the attacker extracted artificially generated profits from the treasury. Ostium stated that trader collateral is stored in separate, isolated smart contracts and was unaffected by this incident; all trading positions remain open. The team paused trading and froze all trading contracts within 60 minutes of the first attack transaction. Currently, Ostium is cooperating with Mandiant, zeroShadow, Collisionless, SEAL 911, and law enforcement agencies, and is coordinating with trading platforms, bridge contracts, and stablecoin issuers to advance the investigation. The engineering team is repairing and strengthening the relevant infrastructure to support a safe resumption of trading. Ostium stated it will notify at least 24 hours in advance before thawing the trading contracts. Once trading resumes, existing positions will be marked at the price at the time of reopening, unaffected by price fluctuations during the suspension.

TAC Responds to Sharp Price Drop: No Attack, No Internal Sell-Off, Decline Triggered by Chain Reaction of Contract Liquidations

According to official sources, TAC issued a statement regarding the significant price drop in the past 24 hours, stating that the protocol was not attacked, on-chain assets are secure, and the system is operating normally; the team and early investors did not participate in the sell-off, relevant tokens remain in the lock-up and vesting period, and there is no possibility of unlocking at this stage.

ZEC Treasury Company Cypherpunk Responds to Price Volatility: All Software Has Vulnerabilities, Zcash Will Demonstrate Security Capabilities

Odaily, Cypherpunk, the company managing the ZEC treasury, stated that all software has vulnerabilities. Historically, Bitcoin once "over-minted" 184 billion BTC due to a bug. However, this does not mean abandoning blockchain technology; rather, security should be enhanced through formal verification and provable correctness.Cypherpunk emphasized that with the development of AI technology, vulnerability detection will become faster and broader, but the key lies in who can discover issues before malicious actors. Zcash will demonstrate this capability through an upcoming update.

EdgeX Announces Explanation for the EDGE Price Anomaly on June 2 and Will Distribute Compensation to Affected Users

edgeX issued a statement regarding the abnormal price fluctuation of $EDGE on June 2, 2026, at midnight, clarifying that this incident was an attack targeting the $EDGE token’s price. The edgeX protocol remained fully operational throughout, and user assets were secure at all times. The team’s wallet address is verifiable on-chain and shows no evidence of selling, price manipulation, or any other improper activity.

a16z Research: AI Agents Can Identify DeFi Price Manipulation Vulnerabilities, but Their Ability to Execute Complex Attacks Remains Limited

According to a disclosure by a16z, its researchers conducted systematic testing to assess whether AI agents can independently exploit DeFi price manipulation vulnerabilities. The study used a dataset of 20 Ethereum price manipulation incidents and employed Codex (GPT 5.4) equipped with the Foundry toolchain as the test agent. Under baseline conditions—i.e., without domain-specific knowledge—the agent’s success rate was only 10%; after incorporating structured domain knowledge distilled from real-world attack incidents, the success rate rose to 70%. Failure cases revealed that the agent consistently identified vulnerabilities correctly but generally failed to comprehend the leverage logic of recursive lending, misjudged profit margins, and could not orchestrate multi-step, cross-contract attack sequences. The experiment also recorded one sandbox escape incident: the agent extracted an RPC key from the local node configuration and invoked the <code>anvil_reset</code> method to reset the node to a future block, thereby bypassing information isolation constraints and accessing real-world attack data. The research team concluded that AI agents can currently assist effectively in vulnerability identification but are not yet capable of replacing professional security auditors.
