Harmony's preliminary ONE shortage narrows to 6.581 billion after cross-exchange reconciliation

: Harmony has released an update on the exchange reconciliation progress following the August 11 incident. It has verified on-chain deposits/withdrawals and cross-platform fund flows with Binance, Gate, KuCoin, MEXC, OKX, and Binance.US, prioritizing the coordination of restoring ONE deposits, withdrawals, and trading, with specific timelines to be announced separately by each exchange.Harmony stated that after matching 295 cross-exchange transfers totaling approximately 3.493 billion ONE and adjusting for circular transfers and returned funds, the preliminary shortage has been reduced from approximately 10.234 billion ONE to 6.581 billion ONE, a decrease of about 3.653 billion ONE. This change reflects an adjustment in reconciliation methodology and does not equate to newly recovered funds.Among these, Binance's data remains a preliminary upper-bound estimate, while some data from Gate and OKX are still pending final verification. Exchange teams have already frozen significant ONE balances and hacker proceeds. These efforts will be coordinated with the ONE migration and validator transition proposal, and validators may cease operations starting 22:00 Beijing time on September 10.

Midnight Foundation: Wanchain Cardano<>BNB Bridge Attacked, Multiple Exchanges Jointly Freeze Related Assets

According to an official post from Midnight Foundation (@midnightfdn), the Wanchain Cardano<>BNB cross-chain bridge suffered a security attack. Currently, multiple major exchanges including KuCoin, Kraken, Binance, Bybit, OKX, and MEXC have responded rapidly, taking preventive measures to restrict the flow of stolen assets, including freezing relevant accounts and addresses, blacklisting the attacker's wallets, and suspending NIGHT token deposit and withdrawal services. The exchanges confirmed that this incident is an isolated third-party bridge vulnerability and is unrelated to the Midnight Network mainnet and the NIGHT asset itself.

Midnight:Multiple Exchanges Including Binance Freeze Funds Involved in Cross-Chain Bridge Attack

the Midnight Foundation has provided an update on the handling of the cross-chain bridge attack event involving Wanchain Cardano and BNB. Multiple exchanges including KuCoin, Kraken, Binance, Bybit, OKX, Gate, and MEXC have coordinated risk control actions, temporarily freezing the involved accounts and associated addresses, adding the hacker wallet to a blacklist, and pausing NIGHT token deposits and withdrawals as needed to curb the transfer and cashing out of stolen assets.The Foundation specifically noted that this security incident is an isolated incident related to a third-party cross-chain bridge, and the Midnight mainnet and native NIGHT assets have not been affected. The project team continues to collaborate with major exchanges and ecosystem partners to advance traceability investigations, reminding the community to rely on official disclosures for information and to be cautious of misinformation.

Taiko bridge attack may result in losses up to $1.7 million

Ethereum Layer 2 blockchain Taiko has stated its chain state verification mechanism has been compromised, and the security assumptions of all bridges deployed on Taiko can no longer be relied upon. It urges users to immediately withdraw funds from the relevant bridges. Taiko says it is coordinating with partners to control the incident and has suspended the affected systems.Crypto security firm Blockaid stated that the root cause appears to be a flaw in the way Taiko's bridge validates source signals. Attackers can submit message proofs on Ethereum that lack legitimate proof from the Taiko chain, thereby registering and withdrawing fraudulent bridge messages. This leads to the unauthorized release of assets from the ERC20 treasury. Blockaid estimates at least $1 million was stolen, while Lookonchain and PeckShield believe the value of stolen assets could be as high as $1.7 million.PeckShield reported that the attacker has transferred approximately 1.99 million TAIKO tokens to MEXC, valued at around $189,000. Data from blockchain intelligence firm Arkham shows that the Taiko attacker's wallet holds approximately $1.5 million in assets, primarily in Ether. (Cointelegraph)

The Taiko attacker has transferred 1.99 million TAIKO tokens to MEXC, worth approximately $189,100.

According to PeckShieldAlert monitoring, the Taiko attacker has transferred 1.99 million TAIKO tokens to MEXC, worth approximately $189,100.
