Zero-click prompt injection? It's a half-click. That's @ben_nassi 's correction to his own use of the term, and on ep. 3 of In the Wild, From Dumbledore to Delayed Tool Invocation, he explains why the gap matters:

Many thanks to @zenitysec_labs and @mbrg0 for hosting me to discuss interesting topics. Here is the second part of the podcast #prompt_injection #LLM #infosec #cybersecurity #promptware
part 2 of my convo w/ @ben_nassi is up on in the wild! we talk about google's response to 'invitation is all you need', CaMeL, beyond the lethal trifecta, half-click ai exploits, BlackHat submission, what is a great talk, and the real world ai security conf

A talk with a great friend on techโ€ฆ
starting with @ben_nassi we talk about the real world ai security conf at Stanford, the best BlackHat talk opener ever staring Dumbledore, building an ai worm with GPT4 back in 2024, and the evolution of promptware available now on youtube, spotify and apple pods youtu.be/9uinwdWXlQ8

Extremely happy to get a Pwnie! Hacking Agentic Browsers was fun this year! Going to post some technical dives today!
here we go. we got the pwnie for best ai sec bug! thank you to all ai vendors for shipping slop browsers for us to hack! @StAJect0r @supriza0 @tamirishaysh @p1njc70r

The first autonomous agent cyberattack is an unprecedented event that deserves unprecedented transparency. Today weโ€™re sharing everything we can: a full technical timeline, an interactive replay, and how we used an open model to defend ourselves, so defenders everywhere can learn from it and prepare for whatโ€™s next. huggingface.co/blog/agent-inโ€ฆ

AI coding assistants are not just helping developers. HalluSquatting, GhostApproval, and GitLost show how attackers can exploit hallucinated repos, fake package names, private code access, and dangerous approvals. Security Now breaks it down. twit.tv/shows/security-now/eโ€ฆ

You can find the talks from Real World AI Security on a dedicated YouTube channel we opened (many thanks to @danboneh for his efforts in uploading them). There are a few missing videos of speakers who did not permit us to upload their talks. For those who asked me for the slides of my talk, here is the link to the video of my talk on the Promptware Kill Chain (co-authored by @BrodtOleg , Elad Feldman, @schneierblog , and @ben_nassi ) Video (on YouTube): youtu.be/JiwSHjBxmqc Paper (arXiv): arxiv.org/abs/2601.09625Real World AI Security (YouTube channel): youtube.com/@RealWorldAISecCโ€ฆ #RWAISec #real_word_ai_security #ai #infosec #llm #security #cybersecurity #promptware #prompt_injection

@Stanford The Real World AI Security Conference 2026, led by Dan Boneh, was incredible. Personal highlights: - Deep convos on AI agent security with red teamers, blue teamers, researchers, builders, and defenders - Great talks from @wunderwuzzi23 and @ben_nassi - @zenitysec Happy Hour - Robot hacking w/ @BT6_Official at @ARIA_research I had the chance to demo live hacking a ROBOT with @BT6_Official: โ€œKinetic Prompt Injection: Live Jailbreak of an Embodied Agentโ€ Huge shoutout to my die hard brothers @PhilDursey, @Ph1R3574R73r, and @Eito_Miyamura for the demo. Great seeing @danboneh, @mbrg0, Keren Katz, John Sotiropoulos, Alan Aqrawi, @wunderwuzzi23, and many others pushing this space forward. AI security is moving fast, but AI agent adoption is moving even faster. It was exciting seeing everyone is attacking this problem from so many different angles. Thereโ€™s still a lot of debate around the role and efficacy of model-level guardrails in defending AI systems. Thanks to @zenitysec for supporting the event. Stay tuned for the robot hacking post. ๐Ÿ‘€

ted โ€ข Visible to anyone on or off LinkedIn My few takeaways from the 1st Real World AI Security Conference. 1. ๐—ง๐—ฒ๐˜…๐˜๐˜‚๐—ฎ๐—น ๐—ฃ๐—ฟ๐—ผ๐—บ๐—ฝ๐˜ ๐—œ๐—ป๐—ท๐—ฒ๐—ฐ๐˜๐—ถ๐—ผ๐—ป๐˜€. Based on the talks given by Google, Anthropic, and OpenAI, I am happy to see that the biggest AI whales improve their mitigations against textual prompt injections.ย My feeling is that their mitigations are at a level preventing 99.9% of the attacks against their systems, allowing only out-of-distribution attacks to bypass. This is a significant improvement from where we were a year ago, when many studies showed how insecure production systems are. 2. ๐— ๐˜‚๐—น๐˜๐—ถ๐—บ๐—ผ๐—ฑ๐—ฎ๐—น ๐—ฃ๐—ฟ๐—ผ๐—บ๐—ฝ๐˜ ๐—œ๐—ป๐—ท๐—ฒ๐—ฐ๐˜๐—ถ๐—ผ๐—ป. I am more concerned at this time about multimodal prompt injections because it seems like less progress is invested in this field. My feeling is that most systems remain vulnerable to multimodal prompt injections. Given that many humanoids will be deployed in the next few years, we must invest significant efforts in securing systems in the latent space against multimodal prompt injections. 3. ๐—ฃ๐—ฟ๐—ผ๐—บ๐—ฝ๐˜ ๐—œ๐—ป๐—ท๐—ฒ๐—ฐ๐˜๐—ถ๐—ผ๐—ป ๐—ถ๐—ป ๐˜๐—ต๐—ฒ ๐—ช๐—ถ๐—น๐—ฑ. The web is rapidly changing in light of the increasing use of agents. Based on Palo Alto and CISPA talks, I believe that the web has become the most common place to meet "prompt injections in the wild". Whether they succeed or not remains a mystery because we are currently lacking the ability to measure their success rate on the client side. 4. ๐—ก๐—ฒ๐˜„ ๐—ง๐—ฒ๐—ฐ๐—ต๐—ป๐—ผ๐—น๐—ผ๐—ด๐—ถ๐—ฒ๐˜€ ๐˜๐—ผ ๐—ฆ๐—ฒ๐—ฐ๐˜‚๐—ฟ๐—ฒ ๐—”๐—ด๐—ฒ๐—ป๐˜๐˜€ Given that the web is rapidly changing in light of the increasing volume of agentic browsing, we will have to develop and adopt new technologies to support this change. I believe newer technologies will be invented in the next few years, and this field will become a focus for academics and industry. 5. ๐—ง๐—ต๐—ฒ ๐—˜๐—ณ๐—ณ๐—ฒ๐—ฐ๐˜ ๐—ผ๐—ณ ๐˜๐—ต๐—ฒ ๐—œ๐—บ๐—ฝ๐—ฟ๐—ผ๐˜ƒ๐—ฒ๐—บ๐—ฒ๐—ป๐˜ ๐—ถ๐—ป ๐—Ÿ๐—Ÿ๐— ๐˜€ ๐—ผ๐—ป ๐—ฆ๐—ฐ๐—ถ๐—ฒ๐—ป๐—ฐ๐—ฒ ๐—ฎ๐—ป๐—ฑ ๐—œ๐—ป๐—ฑ๐˜‚๐˜€๐˜๐—ฟ๐˜†. Based on the talk delivered on how good LLMs have became in finding vulnerabilities in open sources, I expect to see a similar effect in science in general. I am not even sure whether scientists will be the most important leaders in their field in a few years from now, because I believe that most of the significant discoveries will be made by LLMs.ย Scientists and engineers will have to reinvent themselves in light of these changes.
