Spent my entire sunday evening trying to rescue my ENS from a wallet that got drained ~1 year ago.
What started as a simple transfer, turned into a frustrating rabbit hole of automated theft mechanisms.
The plan seemed straightforward: send some ETH for gas to compromised wallet → transfer ENS to a secure wallet
This seemed quite easy, but the moment this gas hit the hacked wallet, it got drained instantly!
Turns out the hacker had deployed a "loserSweep" contract that's been sitting there for a year, constantly scanning the mempool.
Lost all my gas money in seconds.
Yeah, it was my fault to not check this beforehand!
So I pivoted to @flashbots_x bundles - the idea being to bundle both the funding tx and the ENS transfer in one atomic transaction that never touches the public mempool.
But here's the catch: how do you create a transaction from a wallet with 0 ETH? Regular flashbots "fast" RPC won't work.
You need their special bundle simulation RPC that tricks your wallet into thinking it has 100 ETH for tx simulation purposes.
This lets you sign the ENS transfer tx even with zero balance.
Changed my wallet's RPC endpoint to route through flashbots relay instead of regular nodes.
This should have worked in theory: bundles get sent directly to miners, bypassing the mempool entirely, so the sweeper contract can't see the incoming funds until it's too late.
But after multiple attempts with higher gas fees and maxPriorityFeePerGas tips... still failed.
To find the culprit, I fired up @arkham to trace the connections. Found the hacker's main wallet, it points to a CT account @goobi100x that's been systematically draining funds through OpenSea.
My wallet → hacker's intermediary → their main wallet
Now I'm stuck: keep throwing money at Flashbots attempts that might never work, or just let my ENS expire and chalk it up as an expensive lesson?
A year-old sweeper contract still running 24/7, ready to catch any recovery attempts is scary
This is why wallet security isn't just about seed phrases - once you're compromised, the game theory gets brutal.
Anyone successfully rescued assets from a wallet with an active sweeper?
Would love to hear war stories or advice. Otherwise, pour one out for my ENS 🫤



@0xAvious @impranavm_ @0xmouseless shall drop some questions on the server though
