a 10yr old CNN outperforms frontier LLMs on cancer diagnosis it seems inevitable that similar training data will be available to LLMs, and it's surprising that's not already the case the "long tails" of the real world, where precision really matters, continue to need domain specific training lynchlab.net/llm-skin-cancer

PCBs made in America. Twice as fast as Shenzhen. Today @CircuitHub is unveiling The Grid, our factory-scale robot in Massachusetts that builds circuit boards on demand. No changeovers, no per-design setup. Prototypes and production batches, fully automated.

RE: Tailworm 1. The "report" is totally unreadable. I, as someone who is very familiar with reporting vulns and kubernetes, am totally unable to parse the sections on kubernetes. There may be valid bugs, but I can't tell. I would not have reported these as vulns in this state.

we have a new EVM coming up soon that just wrapped audit, it has JIT baked in, it's really fast, and it's gonna be the future of foundry, reth, tempo and all the evm ecosystem using our stuff! huge leap coming. stay tuned.

Reminder that if you have over $10m TVL it’s free to go through STRIDE. If you have over $10m TVL and you haven’t gone through STRIDE, that is wildly irresponsible. Just do it. It’s so incredibly valuable.
Shoutout @asymmetric_re! We recently went through STRIDE at @ImperialPerps. The changes we made as a result of the program have made the incidents of the last few days much less stressful!

100% reliability nodejs brotli exploit takes 5 hours of /goal. No human involvement required
I'll be the first to admit I'm mediocre at exploit development, but I am in contact with enough extremely talented exploit developers to say this for certain: Anyone claiming they were "easily" able to generate a working php2shell exploit with AI is either: a) a world-class exploit developer with an extreme case of imposter syndrome. b) currently looking at some very confident-sounding but wrong LLM output. I'm rather certain it's the latter based on the number of AI-hallucinated exploits I've seen posted on GitHub. Threat actors are also blasting my honeypot network with "php2shell" exploits that not only don't work, but aren't even within 10,000 miles of anything to do with how the exploit actually works. I've seen the same technique from the attached image in multiple alleged "php2shell exploits", including one on GitHub with over 100 stars. Problem is, it's not php2shell, nor is it even a vulnerability at all. It's a technique known as "session poisoning", which can be leveraged to exploit local file inclusion (LFI) vulnerabilities in PHP apps (not PHP itself). The only thing it has in common with CVE-2026-109618/CVE-2026-109619 is they both use the "PHP_SESSION_UPLOAD_PROGRESS" feature. And mitigation advice for both issues reference setting "session.upload_progress.enabled" to "Off". People are shoving loose details of the vulnerability into LLMs, the LLMs are keying in on the "PHP_SESSION_UPLOAD_PROGRESS" string, then generating session poisoning code that has nothing to do with the actual CVE. And because the people doing this have absolutely no idea what they're doing, they're confident enough to post their "proof of concept exploit" to GitHub and share it on social media. So if you see people talking about "session poisoning + LFI" it's likely their LLM hallucinated an exploit based on a 2018 blog by Orange Tsai talking about a local file inclusion attack vector. What's even worse is that "security researchers" are then using LLMs to triage these exploitation attempts, falling victim to the same hallucinations, then confirming there is ongoing mass-exploitation (there currently isn't). The actual real exploit is very difficult to exploit, and so far I've not seen anyone successfully get it working on more than a handful of PHP version with highly-specific configurations. LLMs are useful tools in the hands of skilled professionals, but for others, they're often just a Dunning-Kruger accelerator.
