【Crypto World】An execution layer vulnerability occurred on the Flow blockchain. On December 27th, someone exploited a short time window before the validator execution coordination was stopped to transfer approximately $3.9 million worth of assets off-chain. It sounds serious, but Flow officials clarified one point — this attack did not affect user balances, and everyone’s deposits remain intact and unharmed.

More importantly, the response speed was critical. The Flow Foundation quickly released a fix, and node operators have been coordinating deployment upgrades. The network will roll back to a checkpoint before the vulnerability was exploited, thoroughly removing any unauthorized transfer records. From discovering the issue to releasing the fix and coordinating deployment, the entire process was quite tight. This incident also serves as a reminder — even mature protocols require continuous security monitoring and rapid emergency response mechanisms.

3.9 million USD sounds scary, but as long as user funds aren't affected, it's okay. Anyway, just roll it back.

3.9 million USD vulnerability exploited, but luckily user funds are safe. Gotta give Flow a thumbs up for the quick response.

3.9 million dollars just gone like that? Luckily, users weren't harmed... The response speed is indeed good; just roll back to the checkpoint and it's done.

3.9 million dollars for this? The validator window was stuck for so long before it responded. Luckily, it didn't harm the users' foundation, or else it would have been another feast of cutting leeks.
