Twitter Hacker Is a BitMEX Trader, On-Chain Data Suggests
None of the roughly 13 bitcoin (BTC) acquired through Wednesdayâs Twitter hack have been laundered, according to chain analysis conducted by Samourai Wallet.Â
But whoever it was is deep into the cryptocurrency space, with the BitMEX receipts to prove it, according to preliminary analysis from Samourai Walletâs research arm, OXT Research.Â (A pastebin can be found here.)
âConfirmed, no signs of mixing. Majority of funds spent 1 or two hops and [are] now parked,â Samourai said in a Twitter DM to CoinDesk. âReally curious what their cash-out plan is.â
As of 14:00 UTC, the funds in at least one address are already under the control of Coinbase, Samourai added.Â

âBased on the history of the first destination address of the cryptoforhealth scam addresses, the scammers have a history of gambling on Bitmex and Coinbase usage,â Samourai researcher Ergo said in a Tweet.Â
âThis is peak crypto,â Ergo added.
No coin-mixing involvement (yet)
Overall, Samourai says the hacker only used three Bitcoin addresses and has not sent any funds through a mixing service, as data provider CryptoQuant had previously tweeted. (CryptoQuant has since told CoinDesk it no longer believes the funds have been mixed.)
âAlways a possibility the address is an unlabeled mixer, but I donât see any hints, and one-time use addresses are very common in general and not a definitive pattern for mixers,â Ergo told CoinDesk.
Those addresses, however, linked to other addresses that Samourai tracked to the popular crypto derivatives platform BitMEX.
âEverything from the first address is being spent to this address 1Ai52Uw6usjhpcDrwSmkUvjuqLpcznUuyF, which looks to have been first funded via BitMex,â Samourai said.
Tracking the Twitter hack funds through Bitcoin exchanges
On-chain data allows services to track where funds are moving. In this case, the address had previously been used by a BitMEX trader for moving funds on and off the platform. However, BitMEX has less stringent ID policies, also known as Know Your Customer (KYC), for trading on its domain. So BitMEX may not be so helpful in finding the perpetrator.Â
BitMEX did not return requests for comment by press time.
âAt best investigators can subpoena any relevant account info including IP addresses[;] from there, they can glean some additional info from on-chain data including source of funds,â Ergo said in a private message.
Coinbase, on the other hand, has very strict KYC policies. Ergo said the best chance of identifying the hacker comes from Coinbase.
âOXT Reasearch has also noted a small spend of scammed coins to Binance. Other than the history of 1Ai52Uw6usjhpcDrwSmkUvjuqLpcznUuyF, the links to exchanges and known entities remain minimal,â Ergo said.
