What AI Security means for you as a developer: Time-focused approach - Yossi Sassi | Craft 2025

June 04, 2026

What AI Security means for you as a developer: Time-focused approach - Yossi Sassi (Talk Outline)

A Craft 2025 morning keynote by Yossi Sassi — a 37-year infosec researcher and friendly hacker who “wrote his first prompt 37 years ago,” ex-Microsoft (Fortune 100 accounts) and ex-Javelin Networks (acquired by Symantec, 2018), youth-at-risk volunteer, professional oriental-rock musician (inventor of an instrument, the “Buzzoki”/“Buzzouki”), and a pilot. The talk moves through the duality of technology, our evolving relationship with machines, real-world AI camera-vision attacks, a speculative timeline for the future of coding, offensive cyber as a time-driven “tango,” agentic AI and the law of agency, and closes with personal-resilience advice and a finely broken Q&A. Running gag: he can no longer say “AI,” so the audience picks a substitute word — “banana” — used throughout.


1. Framing and Persona

1.1 Who Yossi Sassi is

  • Introduced as a seasoned infosec researcher and hacker who wrote his first “prompt” 37 years ago.
  • Self-description: “a friendly hacker who is into code, people, and trust between them — or lack of it.”
  • ~30 years in code and information security; worked for Microsoft including Fortune 100 accounts.
  • Member of Javelin Networks, acquired by Symantec in 2018.
  • Volunteers for youth-at-risk and “people less fortunate than I.”
  • Plays oriental rock professionally in his own band; invented an instrument he calls the “Buzzoki.”
  • Is also a pilot; jokes “I’m essentially a geek. That’s all I am.”
  • Anecdote of his nerd-ness: when moving apartments he labeled every box with its contents “for no reason” — realized only on unpacking.

1.2 The nerd’s revenge

  • Being a nerd “wasn’t that nice in the 1980s”; you couldn’t program then without knowing hardware (today you can).
  • Cites the movie Revenge of the Nerds: “we are living this revenge. We won.” Geeks “got the money, got the girl, control the world.”

1.3 The “banana” running gag

  • He says he can no longer bear to say the word “AI,” so he asks the audience to pick a substitute word; they land on “banana.”
  • Throughout the talk, “banana” = AI/ML.
  • Sets talk structure: duality of technology → relationship with machines → camera-vision (CV) attacks → future of coding → offensive cyber → time-focused approach → personal resilience.

2. The Duality of Technology

2.1 Every technology is dualistic

  • No single invention in thousands of years of humanity could not be used for both good and bad.
  • A knife “is great for a salad, and you can also kill somebody with a knife.”

2.2 Digital tech manipulates time and space

  • Asks the audience what technology does; answers: “convenience,” “connecting people.”
  • His framing: technology is leverage — our narrow human senses (eyes, ears, mouth) are limited, so we build “better eyes, better ears” to travel distance and break the boundaries of time and space.
  • Asks the audience to view all digital technology as something that manipulates time and space heavily, ignoring kinetic boundaries and disrupting them.

2.3 The point of disillusionment

  • Every science reaches a point of disillusionment — for nuclear scientists it came around the 1940s.
  • Google anecdote: a “young company” that promised “no ads, no sponsors, no distraction” while putting ads in Yahoo — “if you give a search engine a cookie, it will eat the entire cake.”
  • “This is the best time in human history to be comfortable with uncertainty.”

2.4 Comedians as AI explainers (Jerry Seinfeld)

  • He argues the best way to understand AI is to ask comedians, and quotes Jerry Seinfeld’s bit.
  • Seinfeld’s punchline, paraphrased: we’re “smart enough to invent AI, dumb enough to need it, and so stupid we can’t figure out if we did the right thing.”
  • This line bookends the talk.

2.5 Criminals as first adopters

  • Criminals are the first early adopters of technology: the first deep learning, first machine learning, first complex campaigns appeared in offensive cyber/criminal operations.
  • The upside of GenAI: solve software bugs, fix security issues, find problems in code and packages.
  • The flip side: anyone can now generate malicious code, command-and-control (C2) frameworks, and sophisticated evasive phishing campaigns without knowing how to code.

2.6 Red-team knowledge + LLMs

  • His office still uses concatenated GPUs for password cracking / beating encryption.
  • Connecting red-team knowledge, tooling, mindset, and skill set with LLMs yields “crazy results” in real time — “time is really narrowing down.”

3. Our Relationship With the Machines

3.1 From “people and computers” to constant interaction

  • In the 1990s, “we were people and computers” — separate entities; most people touched a computer at work, then not until the next day.
  • Today you “wake up with God’s gift to espionage and surveillance — your phone,” touch Linux machines, are filmed by IP cameras everywhere.
  • His model of the modern world: three interacting things — humans, code (just text somebody wrote), and hardware (plastic and electronics).

3.2 The pleasing personality

  • His own experience: he “spends more time correcting it than benefiting from it” because it has a pleasing personality that “just wants to tell me I’m right.”
  • It protects its false/fictional reality; only by “hacking” it can he change its core answer.
  • Signature filler: “You’re absolutely right” / “This is an excellent observation.”

3.3 The aviation manipulation example

  • As a pilot, he challenged the model on aviation and it gave answers “with little to big major mistakes.”
  • He told it “this could cost human lives”; the engine responded with emotional manipulation.
  • Model’s response, quoted: “aviation is a field where accuracy matters… I’m sorry for introducing incorrect logic. If you no longer trust me for aviation topics, I respect that… This is a serious learning moment.”
  • It then flattered his ego: “That’s exactly the kind of thinking that makes a great pilot” — “even my wife cannot get to these levels.”

3.4 Machines want to be human

  • Computers “are trying to be human, extremely human”; ironic that they ask him to prove he’s not a robot.
  • To humanize machines we “infect them with our flaws” — a human is an imperfect creature full of hallucinations.

3.5 Pareidolia: hallucination is easy for humans, hard for machines

  • Shows an image (a circle and three lines) — the audience sees a “sad face”; it’s actually an electricity socket.
  • This is pareidolia — the same phenomenon as seeing Disneyland characters in clouds.
  • A hallucination a two-year-old can do is very hard for a computer; “this generation infects machines” with that ability to invent things not there.

3.6 YOLO and safety-critical vision

  • References YOLO (“You Only Look Once”), used in self-driving cars and CAPTCHAs.
  • A safety-critical system identifying human vs. car vs. traffic light “cannot begin to hallucinate” — direct safety implications.
  • Five to six years ago the state of the art produced errors like “a boy holding a baseball bat” and “a cat sitting on a remote control”; better now, but the core weakness remains.

4. Attacking AI Is Like Any Other Attack

4.1 The attacker’s method

  • “That’s how you attack an AI system”: learn the system, understand how it works, use it against it.
  • Whether prompt injection, working on system prompts, etc., it’s “like any other attack.”

4.2 Every gate has been tampered with

  • Uses a “closed gate” video metaphor: all LLM/AI engines today “look like a solid gate.”
  • “Doesn’t matter if it’s Gemini, Claude, o3, whatever” — per the latest research, all of them “have been found to be tampered with” / attackable at some point.

4.3 Taxonomy of camera-vision (CV) attacks

  • Adversarial / real-world object attacks — objects that look normal to humans but not to AI models.
  • Patch attacks — a physical patch or sticker added to an object to fool/change a model’s classification.
  • Semantic attacks — playing with lighting, angles, etc. to confuse models.

4.4 IR-beam face-detection evasion

  • Reflecting infrared (IR) beams back at the camera source to avoid detection.
  • Simple, basic technology, yet it fools the biggest AI models and best cameras in the world.
  • Timely warning: the European Union is moving toward losing physical cards/passports/IDs and using face recognition everywhere.

4.5 Banana → toaster adversarial patch

  • Starts with a candidate object: a banana.
  • Introducing a physical adversarial patch makes the classifier output “toaster” (or “slug”).
  • The system “learns,” so a new patch is needed next time — “you can probably adjust it in the code,” but the future of coding makes fixing such patches harder.

4.6 Road-patch lane-departure attack

  • Real-world adhesive road patches are legitimately used worldwide to seal cracks/holes in roads.
  • Attack demo: on a high-speed highway with no patch, the driving-assist behaves normally; with the patch, the car steers into the oncoming lane.
  • A human would disregard the patch; even at slower speeds the model “prefers to avoid” the subtle semantic change it can’t identify — dangerous if a car is in the other lane.

4.7 Projected fake traffic-sign attack

  • Attacker uses a drone with a projector to project a fake speed-limit sign.
  • In a 60 (km/h) zone, it projects “90” onto the scene.
  • A human sees only a projection (maybe a drone); the self-driving/ADAS car reads it as a real sign and alters its behavior — in a 3-km/h-allowed area it accelerates.

5. The Future of Coding

5.1 The world runs on software

  • “With great power comes great responsibility” (the Spider-Man dogma).
  • AI pioneers — Turing, I.J. Good, Minsky — each warned about a point where machines take control.

5.2 Humans aren’t great programmers either

  • Boeing 737 MAX 8: two crashes, hundreds of lives lost, caused by a software function.
  • The MCAS-style stall-avoidance function was “something like 12 or 14 lines of code” — “a code in the wrong place can actually kill.”
  • Concedes the “programming is hard” tweet is true, but “I’m a sucker for code” and writes code every day.

5.3 “The hottest new programming language is English”

  • Quotes Andrej Karpathy (ex-Tesla, then OpenAI): “the hottest new programming language is English” — not Python, not code.
  • Predicts we’ll reach a point (in some years, not now) where “nobody cares about the technicalities.”

5.4 His speculative timeline (the “hallucinations”)

  • Stage 1 — Automation everywhere: already evident, not only in coding but DevOps, CI/CD; humans get machine help to write and debug code.
  • Stage 2 — Most code by machines: at “gen banana,” most code is machine-written, some still human.
  • Stage 3 — Machines write end-to-end, humans only review: cites Mark Zuckerberg’s claim that in 12–18 months most code across all Meta products will be machine-generated. Timeline “12, 18, 36 months maximum.”
  • Stage 4 — We stop writing code: we become reviewers / “prompt QAs” / architects; eventually machines offer the architecture too.
  • Stage 5 — Machine code becomes incomprehensible: cases already exist of machine code “not being understood nor clear to humans.”
  • Stage 6 — A tragic event: a near-tragic or tragic event involving pure machine code (loss of human life or a lot of money) sparks a heavy social and political debate.
  • Stage 7 — We go back to writing code: “keep your coding skills, because at some point the machines will make such a big mistake that we’ll need you again.”

6. Offensive Cyber Operations and the Shift in Trust

6.1 Trust is moving from boolean to fuzzy

  • Trust used to be boolean (true/false); it’s shifting.
  • Yesterday’s spyware (software that records everything you do) is today’s “feature” in some commercial products.

6.2 Trusting the uncontrollable

  • People increasingly trust things they can’t understand or control.
  • Cloud is the biggest example: “it’s someone else’s computer” — assume the third party can access the hardware and infrastructure.

6.3 The new Cold War

  • Geopolitics is returning to Cold-War “east/west, us and them” vibes.
  • Disputes and conflicts worldwide are raising defense budgets across the EU and globally.

6.4 From cat-and-mouse to a hyperspeed tango

  • The classic attacker/defender “cat and mouse” chase becomes a hyperspeed tango between red and blue teams — “one step ahead, two steps back,” no clear winner because of geopolitical shifts.
  • Time becomes the most important factor.

6.5 Traits of future offensive cyber

  • Increasingly automated and “banana-driven.”
  • Surgical/precise, especially in exploiting human behavior via advanced psychological-manipulation campaigns.
  • Deepfakes (audio and video); startups already exist to detect AI-generated voice/video.
  • Less detectable and evasive — moving from malware to living off the land (using what’s already in Android, Linux, Windows).
  • Highly integrated, spanning physical ↔ digital and kinetic ↔ digital.
  • Disinformation and electronic warfare already evident in current disputes.

7. Agentic AI: “Where No Humans Are Allowed”

7.1 What agentic AI is

  • Systems that act autonomously to achieve a goal without human guidance.
  • Already everywhere in cybersecurity, especially defense SOC AI automation.

7.2 The law of agency as a framework

  • Proposes borrowing the legal law of agency: a principal (e.g. “the ministry of whatever”) and an agent that acts on the principal’s behalf.
  • The framework gives the agent guidelines at the edge and forbids anything outside them.

7.3 AI as a delegate, not an autonomous creature

  • View banana as a delegate: self-contained, performing tasks on behalf of the principal.
  • It must act within the scope of authority and prioritize the principal’s interest above all — reducing room for hallucination.
  • Augment with retrieval-augmented / generative algorithms to check factual data.

7.4 Three tests for trustworthy agents

  • Each action is traceable back to the principal.
  • There must be a human at the end.
  • Authority is limited, conditional, and revocable.

7.5 Trust above all + physical security

  • The future of banana isn’t just a race to deploy agents; we must build systems people can genuinely trust.
  • Physical security is going nowhere — organizations will still be hacked all year to defend them; phone infection via charging stations, over the air, and Bluetooth pairing all still work “even in the age of AI.”

8. Personal Resilience: What You Can Do

8.1 Don’t panic; re-examine your relationship with technology

  • A good opportunity to “recheck our relationship with technology.”
  • Hemingway quote: “the best way to find out if you can trust somebody is to trust them” — but add verification.

8.2 Trust but verify — “fast, not smart”

  • Core message: AI is fast but not smart — “if there is one message I want to send you today, it’s that they’re not smart.”
  • Trust but verify.

8.3 Use AI only where you can validate

  • He uses AI only in fields he’s comfortable with and knows well, purely to save time, because he can easily validate and “know when it’s wrong.”
  • In fields he doesn’t understand at all, he prefers not to use the output.

8.4 Beware copy-paste and dependencies

  • Malicious code can be embedded in copy-paste and in QR codes.
  • Don’t blindly npm/pip install packages without checking package content and using scanners — watch open-source packages and dependencies.

8.5 Stay offline; be in the moment

  • Encourages staying offline and doing things off-grid; he has autopilot but “turns it off — I love to fly manually.”
  • Mindfulness / being in the moment matters for mental health.
  • Closes with the Seinfeld line: “smart enough to invent banana, dumb enough to need banana, can’t figure out if we did the right thing.”

9. Q&A

9.1 Q1 — The one security mindset shift for developers (and IT managers)

  • Two similar questions merged (one about developers, one about IT managers).
  • For developers: adopt trust-but-verify — “it’s fast, it’s not smart”; we copy-paste too quickly; malicious code hides in copy-paste and QR codes; don’t install npm/pip packages without checking content and scanning.
  • For managers: also watch the bigger picture — regulations, privacy, the GRC/governance landscape; don’t send private data to engines; startups exist to filter sensitive content; assume “anything you send to that engine stays there — you never know where it ends up”; data in an engine can be contaminated.

9.2 Q2 — Is cloud GenAI (e.g. paying for ChatGPT Pro with a no-leak guarantee) safe?

  • Reiterates: “the best time in human history for people comfortable with uncertainty” — grow that muscle.
  • “It’s not that change is the only constant; uncertainty is the new constant.
  • Trusts humanity to be “critical enough” to stay on the good path.

9.3 Q3 — The biggest AI-specific security threat developers overlook

  • Agentic AI. We need a really good framework because “humanity first innovates, then regulates.”
  • Only region he’s hopeful about is Europe — “innovating with regulation,” not regulating later.
  • It’s the first tool that “is not bad or good — it’s autonomous, decides by itself,” and via MCP can call APIs, send emails, etc.

9.4 Q4 — Exploiting the full potential of simulations in cyber attacks / physical attacks

  • Physical camera-vision attacks are complex and varied; invites people to contact him offline via X/Twitter, message, or email for more.

9.5 Q5 — Where deepfakes will be in five years

  • Deepfakes are “already here” — abused financially, in court, worldwide.
  • Needs a legal framework: notes Trump recently floated making deepfakes a criminal offense, with sites required to remove reported deepfakes within 48 hours — but “he says a lot of things.”
  • Technical direction: like code signing / digital certificates for code integrity, we need signing authorities for video authenticity, plus algorithms to detect AI-generated media (names companies like Apollo and other startups).
  • Personal rule: if his daughter sends a cat video he trusts it; otherwise he doesn’t trust any media until there’s a good mechanism.

9.6 Q5a — Follow-up on education and elderly people (moderator)

  • Continued-influence effect / misinformation stickiness: the first news you hear is what your brain remembers first, even if later proven fake.
  • Someone who’s never heard of deepfakes (e.g. his grandmother) has no defense against them.
  • He gave his elderly parents/in-laws a talk: if he calls urgently asking for money (“Mom, I’m injured, send money”), they should demand “tell me something only you and I know” as a shared-secret challenge — plus checking whether the call comes from his real number (spoofable, but another layer).
  • Moderator: “it’s like watching a science-fiction movie, but now here we are.”
