Rekt - SingularityNET - RektSingularityNET exploit (19 September 2026): attackers with signing authority exposed through a cloud infrastructure breach drained 8.72M FET from the Ethereum bridge converter, then minted about 2.3 billion AGIX, NTX, WMTX and CGV. Rekt's transaction-level reconstruction puts gross liquid proceeds near $2.29M, not the $16.77M headline, and traces laundering via Chainflip, Baltex and THORChain. It notes conversionIn() skipped checkLimits() and trusted a single EOA signature.

Claude reveals ECDSA curve originsAnthropic's Frontier Red Team reports that Claude recovered how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They are outputs of the C library's lrand48 LCG seeded with 1997–98 Unix timestamps, not hashes of a passphrase. The method scanned for weak-PRNG signatures, then used LLL lattice reduction to recover the truncated LCG state and stepped it back to srand48 initialization. Claude also traced some base points to the FreeLIP/NTL random generator. Reproducible Python is included. The authors say this is not an attack and makes deliberate backdoors less plausible. The B-163 seed and the base points of P-224/256/384/521 and the binary curves remain unexplained.

Anthropic's Frontier Red Team reports that Claude, given no hint, worked out how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They came from the C library's lrand48 LCG seeded with Unix timestamps from 1997–98, not from a hash of a phrase. Claude found this by scanning for weak-PRNG signatures and recovering the PRNG state with LLL lattice reduction. It also traced several prime-curve base points to the FreeLIP random generator. The post includes Python code that reproduces the seeds and base points. It says this is not an attack and makes backdoor claims less plausible. B-163 and the other base points remain unexplained.

ETDI: Comprehensive MCP Security FrameworkETDI (Enhanced Tool Definition Interface) is a proposed security extension to the Model Context Protocol that adds cryptographically signed and versioned tool definitions, OAuth 2.0 scope-based permissions, Cedar-policy-driven context-aware access control (via engines like Amazon Verified Permissions/OPA), and call-stack verification to stop tool chaining and privilege escalation. It is designed to counter two named MCP threat classes — Tool Poisoning (spoofed/impersonated tool definitions) and Rug Pull attacks (post-approval silent modification of tool behavior) — with concrete pseudocode for signature verification, version/integrity checking, and policy evaluation. The page functions as an implementation guide for MCP client/server builders wanting to harden tool approval and invocation flows.

Six defects in one signature verification tool, found from outside in six roundsA forum writeup on ethresear.ch describing a "predictions-first" testing methodology for verification logic, applied against the author's own repository and against a live third-party MCP server (nsgoods Workbench, which offers offline signature verification over the x402 payment catalogue). Six rounds of testing surfaced concrete defects: a false negative caused by a stripped field list, a tamper-accepted body via a service-selection parameter that let callers choose which fields were excluded from the signed message, schema-rejection and signature-failure returning byte-identical error text, and a logging/privacy gap in the operator's system that was fixed after disclosure. The author ships a companion tool, exactzk-verification-guards, which captures both a passing and an actually-reproduced failing run as regression evidence rather than a fabricated example.

Auditing in the age of (good enough) AITrail of Bits describes preparing for a six-month audit of the Miden zkVM (a zero-knowledge VM with its own custom assembly language, MASM) by having AI agents (Claude and Codex) build an LSP server, a decompiler, an abstract-interpretation-based static analysis engine, and a Lean formal model of the VM executor, none of which previously existed for MASM. These tools surfaced a high-severity bug in the mod_12289 procedure where an underconstrained prover-supplied advice value allowed a malicious prover to forge Falcon signatures and drain Miden accounts, plus over 400 type-validation issues, while the Lean proof effort produced 95 machine-checked correctness proofs and caught two additional subtle arithmetic bugs (rotr, wrapping_mul) missed by unit tests.

Pass-the-Passkey Family of AttacksSpecterOps research introduces "Pass-the-Passkey," a family of 20+ attack techniques against passkey/WebAuthn authentication, including three zero-days: Windows 11 logging complete WebAuthn assertions to an Event Log readable by unprivileged users (patched July 2026), Microsoft Entra ID historically failing to enforce WebAuthn anti-replay protections (challenge reuse, session binding, signature counters), and local malware that calls the native Windows WebAuthn API directly to phish users with a convincing native-looking passkey prompt. The write-up argues these implementation failures mirror classic credential-relay attacks like Pass-the-Hash and NTLM Relay, and recommends device-bound passkeys with attestation enforcement for high-value accounts.

The auditor maintains its own Merkle tree of the global phone-number-to-public-key map and periodically signs the tree head, so clients that require signatures from all three auditors can detect a malicious server maintaining a split view within at most one week. This replaces manual safety-number comparison with an automated key-transparency check for end-to-end encryption integrity.

PolinRider Jumps the Fence to Go, Packagist, npm, PyPIOpenSourceMalware documents how PolinRider, a DPRK/Lazarus Group supply-chain campaign tied to the Contagious Interview cluster, spread from GitHub account takeovers into Go modules, Packagist/Composer packages, npm libraries and Chrome extensions without any change to the malware itself. Because Go and Packagist resolve packages directly from git tags rather than a separately-uploaded artifact, a compromised GitHub account automatically becomes a compromised registry release — unlike npm/PyPI, which require a separate publishing credential and largely stalled the takeover at the registry boundary. The post gives ecosystem-by-ecosystem evidence (10 Packagist packages, 80+ Go modules, an NPM/Chrome cluster), IOCs (TRON/Aptos dead-drop addresses, XOR keys, loader signatures, temp_auto_push.bat), a campaign timeline, and remediation guidance for Go/Composer maintainers.

THORChain Exploit Report #2 — GG20 root-cause disclosureTHORChain's second exploit post-mortem details how an attacker who joined as a validator planted a malformed multi-prime Paillier modulus during GG20 threshold-signature key generation, then deliberately failed 864 MTA signing rounds over 2.5 days to leak fragments of other validators' key shares via a combination of three individually low-severity flaws inherited from Binance's tss-lib: an unverified Paillier modulus (the same class documented as BitForge and TSSHOCK), a range proof that didn't bind its two halves together, and an undersized blinding value. Once enough fragments accumulated the attacker reconstructed the full vault private key and drained roughly 10 million dollars in a single transaction before solvency checks could react, since no anomalous fund movement preceded the theft. THORChain is patching the fork, moving from GG20 and Paillier to DKLS and Schnorr based signing, and adding per-validator key-sign failure monitoring as a result.
