#美联储回购协议计划 Wallet suddenly has less money? Many on-chain users have encountered this issue in the past couple of days.

Recently, several experienced users discovered that assets in their wallets were mysteriously transferred out—completely without authorization, and the funds just disappeared. An on-chain security researcher named 0xAA issued an urgent warning on Twitter, saying they detected "a large number of on-chain accounts being illegally transferred assets," and are currently investigating which automated tool might be at fault.

"Still in the investigation stage, but I recommend everyone using related tools to be extremely cautious," said 0xAA, "this is not a small matter."

Based on the security team's advice, you should do the following:

**Immediately stop all suspicious automated trading scripts** — shut down anything uncertain

**Transfer funds from automated systems to a secure wallet** — use verified wallet addresses

**For large assets, temporarily move them to a reputable exchange** — safer during the interim

**Review your authorization records and revoke all unfamiliar permissions** — this is key

The situation is still spreading, with new users discovering theft almost every hour. Ultimately, while DeFi automation tools are convenient, they also become hackers' favorite entry points. Many people neglect authorization management, thinking it's just a connection, but a small mistake can turn into a backdoor.

Regularly check your authorizations, store large assets in cold wallets, enable transaction alerts—these basic practices are now more important than ever. Before fully understanding the cause of certain incidents, it's better to keep an eye on on-chain automation tools—safety first.

Every authorization is a potential risk point. Don't think "I use it carefully," because that mindset is the most dangerous. $BTC $ETH $BNB
