Hackers hijack a dozen DeFi websites, all registered with Name.com, and steal about $138,000

Twelve DeFi websites, including Flap, Kintsu, Pickle Finance and Origami Finance, were hijacked on 30 October 2026 and served the Step Drainer kit. All 12 domains use Name.com as registrar, and 10 were suspended. The Block traced about $138,000 stolen to three EVM wallets, excluding Solana and Aptos losses. Kintsu and Origami blame Vercel. Projects say their onchain contracts were untouched.

Binance Hack: Everything You Need to Know About the Biggest Crypto Heist in History

Decrypt's explainer on the roughly $6.4 billion theft from Binance hot wallets across about 10 blockchains. Binance traced it to a compromised DevOps engineer laptop plus further breach points, and on Ethereum the attacker used 50 pre-signed EIP-7702 authorizations to turn a hot wallet into a sweeper. Chainalysis and TRM Labs attribute it to TraderTraitor; Tether and Circle froze about $2.3 billion.

Appraisal by AI: Model-driven victim prioritization in the VOLTA infostealer

VOLTA (VOLTA-AUTODOXER) is a self-deleting Windows infostealer that, after theft and live session-based enrichment, POSTs an evidence bundle to OpenRouter so an LLM can rank the victim's assets by monetization value. It falls back across a Claude, Kimi and Gemini chain when a model refuses. Talos covers the builder model, the Chrome App-Bound Encryption bypass, the volta_debug.txt artifact and countermeasures such as blocking Chrome --headless.

Polymarket Sends $3.9M Back to Traders After Vendor Script Drain

Polymarket's international site was hit on 29 October 2026 when a page-speed monitoring script served from DebugBear's CDN was replaced with a drainer. It hijacked logged-in sessions for about an hour and took $2.7M from 726 wallets via Polymarket's relayer. Scott Helme of Report URI says the CSP allowlisted every domain used and that hash pinning would have blocked the swapped file. Polymarket is repaying $3.9M, and this is its second vendor-script compromise since June.

A malicious version 2.1.313 of Anthropic's Claude Code extension was served from Cursor's marketplace for about 11 hours on 29 October 2026, reaching up to 5,000 developers. A JavaScript loader prepended to extension.js added an attacker SSH key, a reverse tunnel and macOS/Windows persistence, and reported to 134.209.82[.]225.

A Unified Hessian-Guided Framework for Post-Training Quantization

This preprint proposes a unified post-training quantization framework for large language models. It derives a Hessian-guided approximation of the output change caused by joint weight and activation quantization, using a tractable Fisher approximation. Quantization ranges, linear transformations and weight rounding are optimized together under one output-sensitivity objective. The authors report gains over state-of-the-art transformation and rounding methods in channel-wise and block-wise settings.

Only Accepted Tokens Count: An Energy Accounting of Speculative Decoding Under Latency Targets

This paper measures the energy cost of speculative decoding in SGLang with CUDA graphs on H100 and H200 GPUs, at batch sizes up to 64 across 5 corpora. Savings depend on drafted-token acceptance, which is lower on conversation than code and lower on Romansh than English. Savings shrink as batch size grows, and block drafters can push verification into the compute-bound regime, where speculation raises energy per token.

The ADLC maturity model: 5 stages of agentic development security | Endor Labs

The ADLC maturity model is a proposed five-stage framework from Endor Labs for scoring security controls over coding agents, from unmanaged experimentation to continuous verification. Each stage has requirements on two tracks, agent actions (shell commands, MCP calls, package installs) and agent output (code, dependencies, secrets). It sets stage 3 at deterministic hooks that block actions, gives evidence-based assessment questions, and lists traps such as relying on prompt-level rules.

A staking mechanism forces attackers to train on discovered poisoned samples with flipped labels, producing counter-gradients that remove the backdoor without knowing the trigger. ZKP commitments lock the training data, which blocks adaptive attacks and gradient tampering.

Donating Agent Skills to the Agentic AI Foundation

Simon Willison's link post covers Anthropic's 22 October 2026 announcement that it is donating the Agent Skills standard to the Agentic AI Foundation (AAIF) under the Linux Foundation. Anthropic co-founded the AAIF with Block and OpenAI and earlier donated MCP to it. Willison notes he predicted this in December 2025 and found his old post by querying his blog through datasette-mcp in Claude.

Rethinking Sequence Compression with Test-time Regression

TTR-Compressor is a sequence compression method that treats input tokens as a test-time regression problem. The regression is learned end-to-end by backpropagation, and its coefficients are solved in closed form in the forward pass to give the compressed representation. As a block-wise sparse attention compressor it improves RULER over attention-based compressors by a large margin. As a visual token merger for multimodal LLMs it beats the MLP merger and matches it with 55.6% fewer visual tokens.

Crypto exchange CoinDCX ‘lying’ about $16M hack, say blockchain investigators

Protos reports that on-chain investigators, including Darcy of Salus, ZachXBT and SpecterAnalyst, say CoinDCX misattributed about $16M in outflows from compromised wallets. CoinDCX says the addresses were created in January 2025, compromised in July 2025, and that a sweeping process failed. Investigators cite gas distribution, hot wallet transfers as late as May 2026, and funds sent to Huione and Xinbi addresses.

Major Banks Find Rogue AI Agents Inside Customer Accounts—And They’re 'Horrified'

Decrypt summarizes an Axios report that major U.S. banks are finding unauthorized third-party AI agents inside customer accounts, often using the customer's own credentials. Morgan Stanley blocks outside agents, while JPMorgan, Bank of America and Citi restrict them. Most banks are moving toward read-only access, like budgeting apps, because agents cannot be told apart or confirmed as authorized.

Unboxing Phishing Kits: Huntress Examines 3 Real Kits

Recap of a Huntress Tradecraft Tuesday session (October 2026) on phishing kits that target Microsoft 365 tokens, including EvilTokens (a device-code phishing campaign abusing Railway) and the Kali365 control panel. It explains device-code phishing, adversary-in-the-middle and token replay. It lists detections (unfamiliar cloud sign-ins, device-code auth, new devices) and response steps (revoke refresh tokens, remove rogue devices, block device-code flow).

Signal Vulnerability Lets Malicious Callers Block Hang-Ups

CVE-2026-113380 (CVSS 9.3) is a flaw in RingRTC, the WebRTC-based library behind Signal voice and video calls. A remote peer can flood the call's finite state machine event queue, so the victim's hang-up waits behind junk and audio and video tracks stay live. Fixed in RingRTC 2.72.0 on 4 September; a researcher published details and a conceptual PoC afterward.

SARIA: Persistence-Aware KV Caching with Coordinated DRAM--SSD Reload for LLM Agents

SARIA (Selective Admission and Reload for Inference Acceleration) is a KV caching system that jointly manages DRAM and SSD for multi-turn LLM agents. It persists only blocks likely to be reused beyond DRAM residency, promotes SSD-hit blocks into DRAM for same-session reuse, and paces DRAM reads with a transfer coordinator. Built on LMCache MP, it cuts SSD writes by 57.1 to 58.9% versus full duplicate caching and mean TTFT by 42.3 to 79.7% versus DRAM-only caching.

eMudhra CA compromise: eight private keys, and one of them is 4

eMudhra's eight intermediate CA certificates, chaining to emSign ECC Root CA - G3, had private keys below 256 (one is 4), disclosed on 17 October 2026 by a researcher known as Wayne. Browsers and Microsoft blocked them via revocation pushes, but curl, git, containers, language runtimes and IoT may still trust them. The post gives patched ca-certificates versions, test commands and the timeline.

eMudhra CA Compromise: The Trust Stores You Didn't Patch | Endor Labs

The eMudhra CA compromise (disclosed 20 October 2026) involves eight intermediate CA certificates whose private keys can be derived from the certificates themselves. They chain to AAA Certificate Services and three other roots. Browsers block them, but non-browser clients skip revocation and CT checks. Endor Labs finds 25 popular packages with frozen bundled root stores, 11 already patched, and gives a fingerprint-scanning script, test hosts and patch steps.

Compromised eMudhra intermediate certificates

Cisco Talos describes eight eMudhra intermediate CA certificates (six TLS, two code signing) whose P-384 private keys were trivially recoverable because a flaw in an April 30, 2025 key generation ceremony produced weak keys with only 3 to 8 bytes of entropy. The post lists certificate SHA-256 hashes and serials, browser and Microsoft blocks, and the Go fix (CVE-2026-111943, Go 1.27.3 and 1.26.10) that filters chains by SPKI hash.

Introducing full transaction detection for Cloudflare WAF

Cloudflare announces full transaction detection and response-phase rules for its WAF. Detections evaluate an HTTP request together with the origin's response, so exploitation can be confirmed (for example, path traversal returning a config file) and the response replaced with a 403 block page. Covers managed and custom rules, the limit of three custom response rules, no response-body matching yet, and a first managed rule for php2shell. Available on all plans, including Free.

Browsers Block eMudhra Intermediate CAs Over Recoverable Private Keys

Eight intermediate CA certificates issued by Indian CA eMudhra in April 2025 had private keys generated with weak entropy, effectively all zeroes except the last byte, so they could be recovered almost instantly with baby-step giant-step. Mozilla and Google blocked them on 17 October 2026, Apple on 19 October and Microsoft on 20 October. eMudhra blamed a key ceremony script flaw that created a second, weaker key pair.
