  1. Binance’s $6.3 Billion Hack Puts Developer Machine Security in Focus

    StepSecurity's analysis of Binance's 29 October 2026 incident, which Binance puts at about $6.3 billion in affected assets. It covers Binance's disclosure of a possible DevOps laptop compromise, and TRM Labs and Elliptic findings on 50 EIP-7702 authorizations and a persistent delegation. It links this to the Nx, OVHcloud CLI and Claude Code extension compromises, gives an investigation checklist, then describes StepSecurity products.

  2. ERC draft: Independent Simulation Result for (STVA)

    ERC draft "Independent Simulation Result" (STVA) defines a canonical, content-addressed SimulationResult (success, gasUsed, returnData, stateDiffHash, logsHash, snapshotId, resultHash) that any wallet, hardware device or verifier can recompute from the same VerificationPayload and state snapshot. It targets compromised-frontend and UI/calldata-mismatch attacks, and defines Basic, Standard and Strict compliance levels. Open questions are stateDiff encoding, prestate proofs and binding to capability tokens.

  3. Weekly Research Brief: Binance Hacked; Hyperliquid on Wall Street; Prediction Markets’ Brazil ‘Miss’

    Galaxy Research's weekly brief of 30 October 2026 opens with the Binance hack: about $6.3b drained across 10 blockchains, attributed by TRM Labs and Chainalysis to TraderTraitor (Lazarus-linked). The attacker used EIP-7702 with 50 pre-signed authorizations on Ethereum, and Binance's preliminary finding is a compromised DevOps laptop reaching a service container. Tether and Circle froze about $2.6b. The other sections cover Hyperliquid and prediction markets.

    Galaxy Research newsletter on the roughly $6.3b drained from Binance across 10 blockchains, which TRM Labs and Chainalysis attribute to TraderTraitor. On Ethereum the attacker used EIP-7702 to turn a hot wallet into a sweeper contract backed by 50 pre-signed authorizations. Binance's preliminary finding is a compromised DevOps laptop, with no wallet key leak. Tether, Circle, Ripple and World Liberty froze about $2.7b; Galaxy also assesses Binance's ability to cover losses.

    ERC-8478 is a draft Ethereum standard that binds the x402 payTo address to an ERC-8004 agent's identity, to stop payee redirection by a hijacked domain, proxy or injected tool result. A payTo must equal the agentWallet or carry an EIP-712 delegation signed by it, and the origin must be listed in the registration file. On Robinhood Chain, 5 of 5,575 x402-responding agents used their agentWallet as payTo (28 October 2026).

Later authorizations, including clearing to the zero address, are skipped. It does not protect against private-key compromise.

Losses are estimated at $86 million to over $100 million. The device still passes Genuine Check. It lists safe purchasing, checking and recovery steps, plus BIP-39 passphrase and multisig advice.

  53. PQ-Vault: Provably Quantum-Safe Asset Custody for Unmodified Ethereum

    PQ-Vault is a custody design for unmodified Ethereum against quantum key recovery. It combines a quantum-safe vault contract, a proof-of-stake sidechain with compact certificates, and an optimistic dispute protocol. The paper proves that compact certificates with classically chosen parameters fall from 128 to about 60 bits against quantum attackers, and bounds a seed-update stake-steering attack. For 65,536 validators a certificate is 0.8 MB and verifies in about 20 ms, and the vault accepts a checkpoint for about 420,000 gas.

  54. Wallet Linked to Drift Exploit Sends $61 Million in Ethereum to Tornado Cash

    Wallets tied to the April 1, 2026 Drift Protocol exploit ($295.7 million, Solana) deposited 25,700 ETH (about $61.56 million) into Tornado Cash over two hours, in 100 ETH and 10 ETH batches matching the mixer's fixed pools. Arkham tracks 71 attacker addresses still holding 81,454 ETH. Mandiant attributed the attack to North Korean group UNC6862, and Drift's DFX recovery pool paid early claims about a penny per dollar.

  55. Stolen Ethereum laundering resumes as 25,700 ETH flow into Tornado Cash mixer

    Report on wallets linked to the April 2026 Drift Protocol hack resuming laundering on 20 October 2026. Lookonchain counted 25,700 ETH (about $61.56 million) sent to Tornado Cash in 100 ETH batches, with 81,864 ETH still held. It recaps the six-month fake-VC social engineering, Cursor and VSCode compromise of Security Council devices, and TRM Labs and Chainalysis attribution to DPRK's UNC4736.

  56. ZachXBT Flags $20M XMR Laundering Ring on Hyperliquid

    FreedomXMR (FXMR) is a centralized Monero swap service on Hyperliquid Core that appeared in August 2026. ZachXBT's manual review of every inflow above $10K traced over $20M, more than 87% of volume, to ransomware, malware and exploits including DCENT Wallet, Fetch.ai, Axelar and Gamdom. The admin sources XMR liquidity from KuCoin and won the FXMR ticker in an auction for 518.28 HYPE.

  57. Trail of Bits (@trailofbits) on X

    Trail of Bits thread on Google Quantum AI's March publication of a new Shor's algorithm version aimed at secp256k1, the curve protecting Bitcoin and Ethereum wallets. Google used zero-knowledge proofs to keep the attack details secret, and the post says the secrecy lasted 63 days. The fetched text is cut off after the qubit estimate of roughly 1,200, so later details are missing.

  58. Pre-ERC: Adoption Profile and Reference Kernel for EOAs Adopting Code via SETCODEFROM

    Pre-ERC proposal for EOAs that adopt account code via EIP-8298 SETCODEFROM, which with EIP-8151 retires the secp256k1 key. It lists seven failure modes (FM1-FM7), such as self-recovery lockout, ERC-1271 passing while VERIFY fails, front-runnable initialization and a mutable code source. It proposes requirements R1-R8, a MigrationCheck guard with two routes, and a reference kernel with post-quantum ERC-7913 verifiers.

  59. SlowMist Says Qubic Wallet Keys Could Be Recovered From Six Network Samples

    SlowMist says Qubic wallet private keys could be recovered from six samples observed on the network. Qubic patch 4.26.4 separates new account seeds from the exposed random stream, but leaves header generation unchanged. The page text holds only the headline and subhead, so the attack mechanics, affected versions and any CVE are not stated.

  60. Explained: The Ledger Supply Chain Incident (October 2026)

    The Ledger supply chain incident of October 2026: on-chain analysis estimates $93 million was stolen after devices sold by the reseller CryptoBilis carried an implant with an eSIM. The implant watched the screen during setup, captured the 24-word recovery phrase and sent it over LTE, without touching the Secure Element. Tether froze about $10 million USDT. Reports from Changi Airport and MediaMarkt stores remain unconfirmed.
