Map protocol lost 96% after Quadrillion token exploit

MAPO, the native token of the MAP protocol, plummeted by 96% on Wednesday after the Butter Network Cross-Chain Bridge allowed an attacker to create a quadrillion MAPO tokens.

Malicious mints exceeded the legitimate supply of tokens by tens of thousands of times, sending the price of MAPO from $0.003 to $0.0001 within hours. basis That CoinGecko.

The attacker continued to threaten other pools and exchange listings using a new Externally-Owned Account (EOA) by draining Uniswap liquid pools of around $180,000 worth of 52 ETH. reported Suspension on Wednesday.

This latest exploit comes in a month with at least 18 DeFi and blockchain. Protocols are violatedIncluding THORChain, Verus Protocol Ethereum Bridge, Transit Finance, Trusted Volumes, Ekubo, Echo protocol and RetoSwap.

Map protocol he said. The bug was in Solidity's contract layer, and it halted the mainnet and started migration while the investigation continued. Butter Network has suspended ButterSwap, saying users' funds are not at risk.

In the last post, the map protocol project he said. It notifies a new contract address and selects an appropriate time to perform a property snapshot. “Residual signals captured by attacker-controlled addresses will be completely rejected and will not be included in any future snapshot or conversion process,” he said.

MAPO Attacker Before deploying a malicious contract to a specific address, it first sends a legitimate Oracle Multisig signed message. The attacker is then fired with a modified “retry” message that is identical to the hash but is fake. Verify that the cross-chain bridge is valid and execute the massive token mint.

No private keys were stolen, and no light clients were broken; There was a known Solidity vulnerability involving multiple variable fields; Suspension He explained.

The Map Protocol is an omnichain network for exchanging Bitcoin, stablecoins and token assets on the blockchain, connecting the Bitcoin mainnet with ecosystems such as Ethereum, BNB Chain, Tron and Solana.

Meanwhile, the TON-TAC Asset Bridge, a cross-chain bridge designed as a network extension for the Open Network; Given Posthumous Thursday, revealing his $2.68 million haul on May 11.

There has been a wave of cross-chain bridges in the last few weeks, including the Verus-Ethereum bridge, the Echo bridge, and the Butter network cross-chain bridge.

The “security incident” was caused by a loss of authentication in the serial software, which received a fake wallet that lacked valid code-hash and mint checks on Tons and led to another unauthorized token mint.

Recovery efforts have preserved about 80% of the damaged property, but the bridge remains in place pending an independent audit of the sealed order and liquid restoration.
