BTCPay Server warns of hot wallet thefts targeting outdated instancesBTCPay Server, an open-source self-hosted cryptocurrency payment processor, reports attackers draining hot wallets on instances running version 2.4.1 (July 23, 2026) or earlier. Attackers logged in as administrators on versions older than 2.4.2. Users should update to 2.4.7; the exploited flaw is not disclosed. An October 29 critical vulnerability found by Anthropic's Frontier OSS scanner prompted 2.4.7. The August 7 release 2.4.2 had already warned of an exploited LND credential exposure.

Critical Linux kernel flaw allows remote root attacks on MPTCP serversCVE-2026-98432 is a use-after-free race condition in the Linux kernel IPv4 TCP code (tcp_v4_syn_recv_sock, ireq_opt), affecting kernels back to 4.4 and rated 9.8 by the kernel CVE team (Red Hat rates it 5.9). Anthropic researchers say an unreleased Claude model built an exploit that bypassed KASLR and got remote root on an MPTCP listener in about 53 minutes.

Crypto's Two Answers to AI Bug HuntersBankless article on how crypto is responding to AI-driven bug discovery. It cites Bitcoin Core's 22 October 2026 policy change to fix and ship bugs findable with a simple LLM prompt instead of embargoing them, DefiLlama's 112 hacks over $1M in 2026 versus 70 in 2025, and the Initia exploit (~$2.7M). It contrasts an agility approach (Starknet, bunker mode) with minimalism and AI-assisted formal verification (Anthropic and Theorem proofs across 123 libraries).

Bitcoin Core Rewrites Its Security Policy for a World Where AI Finds Bugs in One PromptBitcoin Core merged a security policy update in October 2026 that adds an "easily discoverable" label for vulnerabilities findable with a simple LLM query. Such bugs get a fix backported to all maintained releases and a new version shipped fast with an advisory, instead of a long embargo. Antoine Poinsot of Chaincode Labs proposed the change after a spike in reports. The article also recaps the Bitcoin Red Team and AI-found Lightning and wallet bugs.

LitPivot: Developing research ideas through dynamic contextualization within the literature landscapeLitPivot is a system from Ai2 and the University of Pennsylvania that helps researchers revise early research ideas when reading prior work changes their direction. It splits a proposal into problem, contribution and evaluation facets, groups papers from Asta Paper Finder per facet, and offers critiques with supporting excerpts and suggested rewrites. In a 17-researcher study, domain experts rated LitPivot ideas as better grounded in the literature than ideas made with a text editor and an AI chat tool.

The rise and fall of Jev hypeThe essay uses the launch of Jev, TypeSafe AI's "System One" general-purpose classifier trained with RLCD, to dissect AI marketing patterns: name dropping, jargon, ambiguity, inflated claims and drama. The author argues Jev's hype peaked and collapsed within about 33 days, while open-weight rivals beat it on cost and performance. It also lists incremental advances since ChatGPT and four unsolved problems: abstract reasoning, continuous learning, embodiment and the economics of running AI.

LLMs are making formal software verification feasible at a much larger scaleAnthropic and Theorem report using Claude to write Rocq proofs that 239 fuzz entry points across 123 OSS-Fuzz libraries never crash on inputs under 64 MB, at the RISC-V binary level (about 180 million lines of proof). Claude patched the bugs it found along the way, including a rediscovery of a libexpat CVE and bugs fuzzers would miss. The post covers trusted components, limitations, token-cost trends and released proofs.

LLMs are making formal software verification feasible at a much larger scaleAnthropic and Theorem report that Claude wrote Rocq proofs of crash-freedom for 239 OSS-Fuzz entry points across 123 open-source libraries, working on compiled RISC-V binaries for inputs up to 64 MB. Proofs total about 180 million lines, and Claude found and patched bugs along the way. The post covers proof reuse (17% fewer tokens), Opus 5.5 using about 40% fewer tokens than Opus 5, and limitations.

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.
