The largest cryptocurrency theft on record took about twenty minutes late Thursday night. Binance began reopening withdrawals Sunday morning, but roughly $6.3 billion left its hot wallets, and about $3 billion of that is frozen, which is not the same thing as returned.
Inside the Largest Crypto Theft on Record
The breach began around 20:05 UTC Thursday. TRM Labs traced some $6.36 billion across ten chains, including 18,270 BTC. The reported mechanism was EIP-7702, which lets an ordinary account temporarily run smart contract code under a signed authorization: fifty authorizations bundled into one transaction, signed with a hot wallet key. EIP-7702 is not a vulnerability. It worked as designed, for whoever held the pen.
Binance says no private key leaked; Blockaid's chief executive suggested a compromised signing system is likelier. TRM Labs and Chainalysis both assessed with high confidence that TraderTraitor, the North Korean unit tied to the Lazarus Group, was responsible. Where a sanctioned entity is the probable counterparty, every downstream handler inherits a sanctions problem whether or not it knew.
Frozen Is Not Recovered
Tether and Circle account for more than $2.3 billion of the freeze, and Arbitrum's Security Council pulled 74,559,805 ARB from addresses linked to the incident. Binance has committed over $6.34 billion from its treasury, SAFU, and insurance reserves, says about 95% of affected assets are replenished, and reopened withdrawals in phases Sunday across fifteen networks, starting with Bitcoin. A reserves snapshot taken Saturday shows ten assets fully backed, with the full cryptographic proof due Tuesday.
Tether and Circle can blacklist an address because their token contracts let them, not because a court ordered it. That stops tokens moving; it does not decide who owns them, and competing claimants can spend years sorting it out. Senator Cynthia Lummis argued this week that the CLARITY Act would have given firms clearer cover to freeze suspicious transactions; the Senate's motion to proceed on it failed September 15. Firms freezing assets today act on contract terms, not statute.
The Market Did Not Wait
Bitcoin traded near $77,170 on Saturday, about 39% off its 2025 high, and US spot bitcoin ETFs saw some $643 million in net outflows on October 30. The detail compliance teams should sit with is CoinDCX, which went reduce-only on futures after a disruption at a liquidity provider it named as Binance. If your user agreement promises continuous market access, concentration in one provider is a disclosure question, not a footnote.
A Hardware Wallet With an Extra Circuit Board
Trezor separately disclosed on October 30 a report of a hardware implant inside a Safe 5: an extra circuit board between the main board and the screen, with a cellular module allegedly able to read the screen, including the recovery backup, and transmit it over a mobile network. The device came from CryptoBilis, a reseller Trezor dropped on October 9. No losses are reported, but Trezor is telling anyone who bought a CryptoBilis device from March 2026 onward to move funds to a new seed. Ledger has confirmed tampered devices from the same reseller.
How to Protect Yourself
Buy hardware wallets from the manufacturer, or a reseller on its current list. If yours came from a reseller named in a warning, move the funds to a brand new seed rather than restoring the old backup; a backup that has been read stays compromised wherever you load it. And a custodial balance is a claim against a company, not property you hold.
If you had assets on an affected platform, preserve records now: statements, transaction histories, screenshots of any suspension notice, and the terms of service in force when you deposited. Those terms usually decide whether you are a general creditor or something else, and often carry arbitration clauses and class action waivers. Where stolen funds are traceable and frozen, claims against the intermediary holding them are time-sensitive. Report losses to the FBI's IC3, and have counsel read any release before signing.
