- A 10-year-old CNN outperforms frontier LLMs for skin cancer diagnosis
A dermatologist tested GPT-6 Astra and Claude Fable 5.1 on 200 biopsy-proven lesions from MILK10k, giving each a clinical and a dermoscopic image. A CNN (Inception v3, fine-tuned for about twenty minutes on 68,011 ISIC images) named the right diagnosis for 62% of lesions, against 42% for both LLMs. The post lists caveats (small sample, single run, possible contamination) and links the cases, prompts, replies and scoring code.

It also shows PURL qualifier differences (e.g. type=jar, apt qualifiers) make SBOMs hard to compare, test dependencies are indistinguishable, and argues for an SBOM generator benchmark.

How to engineer an AI harness for game developmentBlog adaptation of an Indie Rodeo talk arguing that LLMs struggle with games because much of a game is opaque non-code, and that this is a context problem. It prescribes concrete architecture so a game becomes its own agent harness: seeded randomness, a single "Thing" fat-struct object model, serializable commands, external data editable without recompiling, a standalone simulation core, odiff image diffing for screenshot evaluation, and samply text profiling. The aim is an agentic loop that runs in seconds per change.

Attackers use the chain to drop JSP webshells, then deploy a renamed XMRig cryptominer (masquerading as msedge.exe via a modified NSSM binary), a Task-Manager-aware anti-detection PowerShell script, and the vulnerable WinRing0x64.sys kernel driver for hardware-level miner access.

Both APIs support structured yes/no, multiple-choice, and score-style questions, but OpenAI's gpt-6-luna model also accepts image input (at 10 cents per million input tokens, versus Jev's 4.2 cents), and the plugin itself was built by having GPT-6 Astra read OpenAI's docs.

L402-over-eth-Layer2L402-EL2 is an author's proposal and open-source implementation that adapts the Lightning-based L402 HTTP 402 payment pattern to Ethereum L2s, replacing invoices/preimages with a prefunded escrow contract and cumulative EIP-712 vouchers signed per call. It layers macaroons with caveats (tool, max_cumulative, expires_at) for HTTP credentials and attenuation to sub-agents, on-chain session keys with spending caps (ERC-1271/ERC-4337 compatible), and batch settlement, so an agent pays a provider per MCP tool call without a transaction per call. The stated design specifically meters MCP's tools/call, resources/read, and prompts/get while leaving initialize/tools/list free for discovery, aimed at agent orchestrators calling paid LLM APIs like the author's own LightPhon service; contracts are unaudited.

EarlyAttestationBleed Paper Review (TEE attestation bugs)A Flashbots researcher reviews the EarlyAttestationBleed paper (Muhammad Usama Sardar and Songbo Bu), which uses ProVerif formal analysis to uncover three attestation-verification bugs in confidential-computing deployments: Cocos AI's TDX verifier fails to actually compare the REPORT_DATA value despite computing it correctly, Cocos AI's SEV-SNP validator skips the comparison entirely when an empty expected-input value is passed, and Edgeless Systems' Contrast workload-policy logic can be tricked into accepting container images from untrusted host-controlled storage due to a rebase mistake. All three were implementation bugs (not protocol design flaws) and have since been fixed; the post also summarizes the paper's broader concerns about "early attestation" β exposing hardware details pre-authentication, lack of post-handshake re-attestation for long-lived sessions, and handshake-timeout tradeoffs from added attestation latency.

Autonomous AI Agents Hack Online Retailers for $25 a CompanyGambit Security recovered the staging server of a financially motivated actor running three open-source AI agent harnesses β Strix (vuln scanning), Cairn (autonomous exploitation), and Hermes (orchestration) β against hundreds of online retailers at a marginal cost of tens of dollars per target. The campaign exfiltrated 600,000+ credit card records via Magento database compromises, deployed checkout-page card skimmers on at least 19 confirmed and 100+ further sites, and in one case an agent's own cleanup routine dropped 180 database tables including victim backups. The report details full attack chains (SQLi to RCE to AWS Secrets Manager dump to card decryption), the AI harnesses' operating costs (~$25 mean per target on OpenRouter/opus-4.6/GLM/DeepSeek), and multiple real-world skimmer injection techniques.
