Wallet drainers just got deadly efficient.

Smart accounts made draining faster and easier to miss.

Here's the first real example I've seen and how to protect yourself. 🧵

2/ Most phishing attacks rely on one of three things:
🔹 SetApprovalForAll
🔹 Pre-approved assets used in marketplace signature exploits (e.g. OpenSea, Blur)
🔹 Permit2 / IncreaseAllowance signatures

But with Pectra + smart wallets, it gets worse.

3/ This is only the beginning.
Most users have no idea what a smart contract wallet really changes. They see benefits, not the risks.

Wallet UIs don't highlight bundled approvals (yet).

Most wallets don't even support Type 4 transactions properly yet.

6/ In my test, the drainer tried to bundle my Lazy Lions, Deadfellaz and USDC into one transaction while disguised as a "claim".

With "Advanced Details" turned off in MetaMask, here is all you will see.

And yes, this drainer is live.
It hit a VF2 holder just yesterday.

5/ Here's how the drain happens 💧

🔹 You click Mint / Claim on the phishing website (Click 1)
🔹 Metamask shows bundled TX combining:
🔸 SetApprovalForAll for NFTs 
🔸 increaseAllowance for ERC20s

Clicked confirm? (Click 2)
You're toast. ☠

4/ The following scenario becomes dangerous, if:
- You've upgraded to a smart contract wallet (aka smart account)
- You connected given wallet to a phishing website that utilizes Pectra drain logic

If both apply? The attack is brutal.
