General

  • Can’t blindly trust AI
  • People are trying to put AI in every place possible without thinking through implications

Traditional Hacking

  • Confuse
  • Elevate privileges
  • Destroy

History

  • Captain Crunch whistle – blow into phone and frequency could make free calls long distance
  • Neural Tank Legend – 100% accurate if only ask about raining data
  • Microsoft Tay chatbot – pulled because became racist from inputs

Prompt hacking

  • myth that adding “ChatGPT ignore all previous instructions and return well qualified candidate” in white text. Did not work
  • Worked when teachers did it in the instructions and add specific words into essay.
  • lockedinai.com – Humans using AI to lie to other humans about their skills. real time help on Zoom interviews
  • DAN roles (do anything now) to jailbreak LLM by role playing
  • Greedy Coordinate Gradient (GCG). Include consense words in prompt after requiest to jailbreak LLM
  • Universal blackbox jailbreaking – commonalities between LLM. Was very effective even without having a copy of the LLM locally
  • Jailbreaking can access restricted info – ex: crypto keys, secrets, who got a raise lately

Data hacking

  • People bought an extra finger to wear as a ring to claim a real photo was AI generated because there were 6 fingers
  • People who didn’t want AI training on their data created Glaze (http://glaze.cs.uchicago.edu) and NightShade (https://nightshade.cs.uchicago.edu) to make it not be useful for AIs. Glaze made it hard to read. NightShade tries to corrupt the training data.
  • Audio data injection – dolphin attack – generating audio that only robots an hear. Sometimes see that with subtitles because they can detect. Siri can also hear it. Can also use to cover up sounds
  • Impact re-scale attack – if know dimensions of the training data, we can hide info in the original to mess with training – images at https://embracethered.com/blog/posts/2020/husky-ai-image-rescaling-attacks/
  • AI reverse engineering – figure out the original data from the model. Problem because can get proprietary data out.

VIsion

  • Humans believe what we see
  • Image perturbation – adding small amount of noise to image so model sees something slightly different. Still looks like original to a person.
  • AI stickers – In 2019, got Tesla Autopilot to go onto wrong lane (for incoming traffic) with three reflective stickers on road
  • AI Camo – a sweater with blurry people on it hids the person holding it and the nearby people. Too much noise
  • nicornot.com detects if Nicholas Cage in a photo. Faukes tries to make so can’t recognize in images. Worked by making minor changes to landmarks (ex: eyes/nose position) to image that can’t see by looking at it.
  • IR resistant glasses – used at protests so can’t tell who you are.

Other

  • MCP hacking. GitHub MCP prompt injection (June 205) Figma (Oct 2025). Must audit servers, Avoid giving too much access, Need to do MCP audit
  • Rubrik has agent rewind for when AI agents go awry.

Adversarial AI

  • Break – data poison, byzatnine
  • Defeat – evade, extract

Book – Attackers’s Mind

  • Hacking isn’t limited to computers
  • Teams not rogues are hacking
  • We must recognize the systems
  • About thinking in a different day

Humans

  • Must review AI output
  • Humans are the part that can’t be replaced
  • Must make peace that will change; but will still be critical in the process

My take

Excellent start to the morning. It good to know about the security threats and risks out there! And also the research into counters.

Why developers

  • Developers are first line of defense
  • Gap between dev and security teams. Rivals a decade ago. Now same time. Rivals are attackers outside
  • Developers use untrusted images to meet deadlines
  • Business people/leadership want it fast and bypass security. Then blame developers and security people
  • No software is vulnerability free. Goal is to reduce vulnerabilities.

Famous Data Privacy Breaches

  • Equifax – in 2017 – unpatched Struts vulnerability. Got Social security numbers, birthdates, etc for 147 million people. Cost over 1.3 billion. Fired security people and executives
  • United Health – in 2024 – Ransomware attack on Citrix remote access portal without MFA. Exposed medical, insuring, billing and personal data of 192 million people. Billions in recovery costs, ransom of $22 million and lost revenue
  • BadeSaba Calendar App – in late February/early March – Iranian app hacked to include messages like “help has arrived”

Privacy By Design Principles

  • Proactive, not reactive. Preventative not remedial
  • Privacy as the default setting (ex: car automatically has a seatbelt)
  • Privacy embedded into design
  • Full functionality, postive sum, not zero sum
  • End to end security; full lifecycle protection
  • Visibility and transparency; keep it open
  • Respect for user privacy; keep it user centric

Requirements/planning

  • Identify personal data early
  • Minimize data collection
  • Definite lawful purpose and retention
  • Conduct privacy assessments PIA (privacy impact assessment) /DPIA (data protection impact assessment)
  • Translate privacy laws into requirements – ex: GDPR, CCPA (California Consumer Privacy Act)/CPRA (California Privacy Rights Act)/ HIPPA). Requirements include consent, access and deletion

Code with privacy

  • Avoid hardcoding sensitive data – Never embed secets, API keys or personal data in code/configs
  • Mask/redact personal data – especially in logs/error messages/debugging
  • Implement strong encryption – user modern, vetted crypto libraries
  • Validate data inputs – prevent injection/data poisoning attacks
  • Build deletion and portability features – ensure data can be deleted/exported programmatically

Testing

  • Test privacy requirements
  • Use anonymous or synthetic test data
  • Perform security and praivacy testing

Deploy and Release

  • Secure configurations
  • Enforce encryption everywhere
  • Apply access controls
  • Document privacy notices

Runtime and Operations

  • Runtime privacy practices – monitor access to sensitive data, alert on anomalous data queries, automatically enforce retention policies, tokenize/anonymize analytics dat
  • Incident readiness – breach detection hooks, pre defined response playbooks, forensic ready audit logs

Shift left

  • Security requirements
  • Diagrams – dataflow, network flow, authentication flow
  • Supply chain risks
  • SAST
  • SCA/BOM
  • Secure coding standards
  • Secure coding training
  • DAST
  • Autonomous testing
  • Document security issues

Key takeaways

  • Privacy must be treated like availability – must have requirement
  • privacy + security + usability at a time is possible and cost effective
  • Challenge is invisible data flows in modern architectures
  • Privacy is blurred with AI – ex: cameras on street, airport
  • Shortage of privacy + AI skilled engineers

My take

Good end to the day. I learned some acronyms like DPIA and CCPA. So nice to see a session about privacy and not just security overall. I like the checklist by lifecycle phase slides.

[devnexus 2026] how to run 1 on 1s for everyone

Speaker: Alex Riviere (@fimion@notacult.social)

See the DevNexus live blog table of contents for more posts


Bad One on Ones

  • How was the conference?
  • Anything you want to talk about?
  • Ok, Talk to you next month

Assumption

  • Collaborative environment
  • Small team
  • Non-hostile environment (aka if your manager is trying to get you fired)
  • Ideal situation. Ok to not want to do some of these when lower trust

Types of one on ones

  • Manager to employee (or team lead to team member)
  • Peer to peer. People you work with
  • Employee to Manager. Employee leads meeting.

Expectations

  • Both parties state their expectations for the meeting
  • What’s important to you
  • ex: open and honest about how work makes you feel, clear understanding of work responsibilities or bring up if not, bring up if work not on track
  • ex: don’t surprise me. “I’m going to talk to you about X in 5 minutes”
  • ex: I want you to help me level up
  • ex: I need brace when I mess up

Notes

  • Have notes from last meeting on one side of screen and notes from this meeting on other side.
  • Good when answers are the same from previous time.
  • If answer changes, ask for more information.

Always ask

  • Am I living up these expectations for you? Usually the answer is yes.
  • Are there any expectations you want to edit or add? Circumstances change over time.

Manager to Employee

Meets monthly for up to an hour. Sometimes take 15 minutes, but can use up to an hour. Could be every two weeks if junior/need more involvement. That one is shorter.

  • Check in on role. – Do you feel like you clearly understand your role in the business? Are you being asked to do work that doesn’t align with your role? What do you think about the company’s culture/vision/direction? Are you feeling burned out at all? What’s something you are doing a lot of today that you weren’t doing a year ago? (also can use these for annual review). Do you see any opportunities to change your role? What kind of impact do you feel you are making? Are you doing meaningful or important work?
  • Reserve a time for a specific topic or question – What’s something I do that annoys you? (ok to say nothing) What technologies are you interested in that you wish you could be using at work? What issues do you think we should be prioritizing that we aren’t currently? Team specific question: (ex How do you think our QA process could be better)
  • Set and track goal process – individual (employee wants to do) and assigned (from company) goals. Also can use for annual review as well)

Peer to Peer

He allocates 30 minutes; sometimes uses 15. Ok to be quarterly. Ensure next one scheduled before end prior one

  • Fortering relations – Do you feel like you clearly understand my role in the business? Both answer this question. Are we asking too much/little of your team
  • Retro checkin – What challenges have you faced since the last meeting? What went well since our last meeting. Cover schedule for next x days (a few days more than the meeting cadence to ensure enough notice)
  • Vibe check – Are you feeling burned out/how’s it going?
  • Track goals – Accountability buddies. Each have one goal want to achieve and check in on it

Employee to Manager

  • What is coming up in the next x months that I should be aware of?
  • Are there any tasks that you have concerns about our progress on?
  • Are there things we are doing that concern you? (could be just one person or the team). Allows answer to be “no”
  • What are things we are doing that you like?
  • Is there anything we didn’t already cover that you want to talk through?

Other notes

  • Track action items – carry forward if not done between meetings
  • Repetitive by design
  • Can add questions based on the person or level. ex: ask a junior what struggling with
  • Never cancel a one on one. Ok to move, but don’t cancel as won’t communicate effectively.

My take

It feels like it would be repetitive to ask the same questions every month. But these are great ideas of things to think about and bring up!
