A recent $440K heist just exposed something disturbing—Ethereum's 'Permit' function is becoming hackers' favorite playground.



Here's the scary part: these aren't your typical phishing attacks. The permit mechanism, designed to streamline token approvals, is now being weaponized. Victims unknowingly sign what looks like a harmless transaction, but they're actually handing over complete control of their assets.

The attack pattern? Sophisticated. Scammers disguise malicious permit calls within legitimate-looking DApps or airdrops. Once you sign, boom—your wallet's drained before you realize what happened.

Why is this blowing up now? Two reasons. First, more protocols are implementing permit functions for better UX. Second, users still don't understand what they're signing. That split-second approval could cost you everything.

The brutal truth: this $440K case won't be the last. As DeFi grows, so does the attack surface. Until wallets build better signature verification warnings, we're all playing Russian roulette with our approvals.

Stay paranoid. Verify every signature. Your future self will thank you.

Damn, this permit function is really outrageous, and it was accidentally hollowed out --- It's approve's fault again, and you have to slowly read each signature clearly --- $440k is gone because you pressed a button? DeFi has to live more cautiously --- The original intention of the design of permit is good, and it is really uncomfortable to be ruined --- The problem is that the wallet warning is not enough, and users can't react at all --- I've seen too many approve-related rugs, and now I have to think twice about signing anything --- I can steal $440k on this, and I have to check what pending approval I have in my wallet --- Permit mechanic doesn't sound complicated, but it actually gives hackers too much room to operate --- DeFi users have to be a bit paranoia to live, and it's no joke --- Why can't wallets be made a little more foolish, not that we all need to understand the details of signatures?

Damn, is permit causing trouble again? This time it’s really a bit outrageous... --- It’s always approval causing problems, I don’t dare to sign anything carelessly anymore, man. --- Really? I almost got caught by this last time too, luckily my friend warned me. --- So now we can’t even claim airdrops casually, right? --- These hackers are really thorough, it’s disgusting. --- I’ve said it before, don’t just click approve, why do people keep falling for it? --- 440k gone? That hurts... permit’s fault again.

$440,000 just gone like that? Should permit really be banned? --- Sign a message and your wallet gets drained. This move is just outrageous... How careless can you be? --- Blaming wallets again. When will we finally get a reliable verification mechanism? --- I told you not to click approve so casually, see what happened now. --- The permit function itself is problematic. What kind of UX optimization is this? --- Every time I have to review signatures like I'm reading a contract, it's so annoying. --- DeFi is getting more competitive, hackers are getting more ruthless, you really have to be paranoid. --- Stuff like this is bound to happen to me sooner or later, I just know it. --- Looking at these cases, it feels unsafe to keep anything in my wallet now. --- Why are there still people signing things when they have no idea what they're doing?

Another incident with the permit function... Seriously, now I have to think twice before approving anything. --- $440,000 just gone like that? You can't even react in the moment you sign. --- These things are getting nastier, feels like there's a new trick every month. --- Honestly, it's still because users don't understand. Wallets need to roll out warning mechanisms ASAP. --- Oh my god, I'm afraid to even claim airdrops now... You have to be really paranoid. --- Permit is definitely convenient, but now you have to use it with extra caution. --- Say no more, just thinking about it makes me anxious. One-click approval is really a suicidal move.

Another permit pitfall... This thing is really impossible to guard against, one signature and it's all gone. The permit mechanism was originally meant to optimize user experience, but now it's become a tool for fleecing newbies—ironic, isn't it? $440k is just the beginning. DeFi is like a big casino; you never know what will happen in the next second. Honestly, now every time I approve something, I have to think it over for a long time, afraid I'll accidentally fall into a honeypot. No matter how good wallet warnings are, it doesn't help; the real problem is users are too inexperienced—myself included.

Oh my god, it’s the permit function again... No wonder there’s less money in my wallet recently, turns out I signed a fake airdrop. I’ve said it before, those transactions that look totally normal are the most dangerous—I’m not exaggerating at all. People really need to get into the habit of being as cautious as defusing a bomb every time before approving anything. I just don’t get why these protocols are designed to be so easy to exploit. No matter how good the UX is, it’s useless. Permit really feels like a vulnerability tailor-made for hackers. Now it’s too late for regrets. Looks like wallets must strengthen their warning mechanisms, otherwise we’ll all have to live super cautiously.
