Polkadot bridge vulnerability exploited, 1 billion DOT tokens minted on the Ethereum network and sold off

According to PeckShield monitoring, 1 billion DOT tokens were anomalously minted and sold on the Ethereum chain.
On-chain data shows that about an hour ago, the attacker manipulated administrator permissions, transferred contract control to a malicious address, then minted 1 billion DOT and immediately sold, causing the price to plummet from $1.22 to nearly zero.
The incident is still developing, and Polkadot's official response has not been issued yet. The attack targeted bridged assets on Ethereum, not the Polkadot native chain.
