    Ep50: Arrested in a State She'd Never Visited: The Cash App Account in Her Name

    Episode Summary: In this short episode, Marc covers 404 Media's reporting on Amanda Smith, a Pennsylvania woman arrested on an Arkansas warrant after someone opened a Cash App account with her Social Security number and date of birth and used it to collect $1,000 from a Facebook Marketplace scam. He walks through how investigators tied the account to her, the account details that don't match her, and why Cash App wouldn't share account information with her. The case is ongoing and Smith is presumed innocent. Marc closes with one record you can start keeping this week. Key Topics Covered: The arrest: a warrant from Arkansas, a computer fraud charge, and three nights in jailHow police got to her: a hacked Facebook account, a fake Marketplace sale, and a search warrant to Block, which owns Cash AppThe data that didn't match: a Philadelphia address, an iPhone running a 2022 operating system, and a Verizon connection when she's on AT&TWhere the case stands: Cash App wouldn't share account details with her, she turned down a plea offer, and a hearing is set for November Main Takeaways: Identity theft isn't only a money problem. Stolen identity data can attach your name to someone else's crime.In this case, a Social Security number and date of birth were enough to put Smith's name on a payment app account.The details that didn't line up were the address, the device, and the phone carrier.Write down which accounts are actually yours: your banks and payment apps, your phone number, your carrier, and your devices.

    Ep49: ChatGPT Ads: Your Prompts, Your Email, and the Switch That Doesn't Stop Ads

    Episode Summary: ChatGPT now shows ads on its Free and Go plans. In this episode Marc walks through what 404 Media found when it ran its own test ads: advertisers can upload lists of emails, phone numbers, or Android advertising IDs, and your current chat shapes which ad appears. Turning off ads personalization changes how ads are picked, but it does not stop them. Marc covers what each setting does and five steps you can take today. Key Topics Covered: 404 Media's test ads: how Joseph Cox used OpenAI context hints to steer ads toward privacy and AI chatsCustom audiences: email, phone, hashed identifiers, and Google Advertising IDs, plus include, exclude, and bid-adjustment bucketsThe two switches: Personalize ads vs Ads-Free mode, and why one does not equal the otherWhat OpenAI commits to: advertisers do not get your chats; Temporary Chats show no ads; health and politics limitsFive actions: check your plan, Data Controls, delete ads data, Temporary Chat, and shrink the lists you are on Main Takeaways: Free and Go show ads. Plus, Pro, Business, Enterprise, and Edu do not.Context hints are guidance, not keyword triggers, but your prompt still decides whether an ad fits.Advertisers can match uploaded emails, phone numbers, or Android advertising IDs to ChatGPT users (inclusion and bid bumps need at least 25,000 matched users).Turning off ads personalization still leaves context-based ads on. Ads-Free (Free plan only) or a paid plan is what removes ads.Your personalization setting does not take you off an advertiser's uploaded list.For sensitive topics, use Temporary Chat. It shows no ads and does not use or update memory.

    Ep47: Why AI Risks Are Different

    Episode Summary: Someone told Marc that AI panic is nothing new — just the printing press or nuclear weapons all over again. He disagreed, and it turns out there was a report to back it up. In this episode he breaks down why AI collapses the cost of dangerous capability in a way the printing press, the internet, and even nuclear weapons never did, what Anthropic's brand-new September 2026 threat intelligence report documents, where his own "$200 expert" framing overstated the case, and the four guardrails that would close the gap. Key Topics Covered: The argument that started this episode — a debate about whether AI panic is history repeating, and the report Marc found three days later making his case for himWhy the printing press comparison breaks down — institutions had a century (and decades, for the internet) to catch up; AI's capability curve moves in monthsWhat's actually different about nuclear weapons — nuclear risk lives behind physical choke points: materials, facilities, expertise. AI risk lives in a skill, and skills can't be fenced offAnthropic's report: the receipts — three disrupted operations, walked through case by case, that turn the argument from speculative to documentedDoes AI make anyone an expert? Not exactly — Marc's own "$200 subscription = expert" line, and the more defensible version of the claimAttackers, defenders, and who adapts faster — the same models cutting attacker costs are cutting defender costs too, and why that race mattersWhat real AI guardrails would look like — four concrete guardrails: pre/post-release capability testing, enforceable standards, international coordination, and risk-scaled access Main Takeaways: AI doesn't need generations to reach scale like the printing press or the internet did — model capability jumps happen every few months, not every few decadesNuclear risk is contained by physical choke points (fissile material, facilities, expertise); AI risk lives in a skill, and skills don't have a border to fenceAnthropic's September 2026 report documents real, disrupted operations — including a breach that went from one stolen developer token to full cloud admin control in roughly three hours"$200 subscription = expert" overstates it: AI doesn't manufacture expertise, it lowers the skill required to attempt tasks whose consequences the operator isn't trained to handleDefenders get the same acceleration attackers do — the organizations lagging on AI-assisted defense are the ones absorbing the most riskClosing the gap takes four things: pre/post-release capability testing, enforceable (not voluntary) standards, international coordination, and access that scales with risk instead of price Timestamps: [0:00] The argument behind this episode[1:03] Why the printing press comparison breaks down[1:53] What's different about nuclear weapons[2:55] Anthropic's report: the receipts[4:46] Does AI make anyone an expert?

    Ep46: Vulnerability Prioritization: Why 98.5% of CVEs Are Never Exploited

    Roughly 98.5% of all known CVEs have never been exploited. In this episode I break down a conversation between Jeremiah Grossman and Robert Hansen of Root Evidence, and host Raphael Mudge, on the Down the Rabbit Hole podcast, and what it means for how you prioritize a patch queue. I cover CVSS score versus exploitation evidence, how to use CISA's free KEV catalog, why the vulnerability management industry has no incentive to tell you the truth, and what separates a junior-sounding answer from a senior one in a security interview. In this episode: (00:00) The scan report that isn't as urgent as it looks(01:03) The 98.5% number and the mechanic analogy(02:01) Why the industry defaulted to patch everything(03:00) The 36-hour outage from a perfect-10 patch(03:48) CVSS score vs. exploitation evidence vs. insurance-claims data(05:08) What it sounds like when someone understands this in an interview(06:15) Why the industry has no brakes, and the AI-hype myth(07:49) Your homework Links: Down the Rabbit Hole, episode 722, "Vulnerability Math Ain't Mathing"CISA's Known Exploited Vulnerabilities (KEV) catalogFIRST.org, the CVSS specificationFull written breakdownOur cybersecurity career guideBreaking into cybersecurity with no experienceThird-party risk and the AI bug-report flood Not financial or legal advice.

    Ep45: Fired for Failing a Phishing Test? What Binance Actually Does

    Episode Summary: Binance fires employees who repeatedly fail its monthly phishing tests — while the entire security-awareness industry insists you should never punish someone for clicking. In this episode Marc breaks down what Binance actually does, whether you can really get fired for failing a phishing test, how corporate phishing simulations work, and what a program looks like that takes security seriously without torching its own culture. The honest answer isn't at either extreme. Key Topics Covered: What Binance's red team is doing — monthly tests, recruiter and fake-conference lures, and mandatory remedial training for anyone who failsCan you really get fired? — the "three strikes" model and the 2019 Krebs on Security debate over whether a failed phish test should be a fireable offenseHow corporate phishing tests work — the baseline click rate, the "gotcha" landing page, and the Hoxhunt failure-rate ladder (no program 20–35% down to highly mature 2–5%)"Weakest link"? — the industry split between Hook Security's "never punish a click" and the accountability camp, and where Marc landsAccountability without a blame culture — four principles for getting Binance's seriousness without the fearThe boring middle thing that actually works — train relentlessly, test fairly, measure reporting, and save real consequences for real patterns Main Takeaways: You usually can't get fired for a single click — real programs reserve consequences for repeated failures in high-risk roles, not one slip-up someone ownedPunishing clicks backfires: people who fear consequences hide mistakes, and a hidden compromise turns a five-minute cleanup into a five-month incidentThe metric that predicts resilience is report rate, not click rate — reward the people who spot the phish and hit "report," loudlyHumans aren't the weakest link; untrained, unsupported humans are — most failure is the program, not the personFair escalation targets the overlap of three things: repeated failure, high-risk access, and refusing to train or report Timestamps: [0:00] The gotcha that shows up on your performance review[1:03] What Binance's red team is actually doing[2:23] Can you really get fired? Three strikes and the Krebs debate[3:34] How corporate phishing tests work, and the Hoxhunt failure-rate ladder[5:03] "Weakest link"? The industry split, and where we land[6:55] Accountability without a blame culture: four principles[8:19] The boring middle thing that actually works Tools & Resources Mentioned: Binance runs monthly phishing tests (crypto.news)Repeated failures may lead to dismissal (WEEX)Addressing the repeat phishing offender (IT Brew)"Should Failing Phish Tests Be a Fireable Offense?"

    Ep44: California's DROP Tool: Delete Yourself From Data Brokers in One Free Request

    Episode Summary: California just made deleting yourself from data brokers a single free request. In this episode Marc breaks down the state's new DROP tool: what it deletes, how to file it in a few minutes, why August 1, 2026 is the date that matters, and the three things it won't fix. If you're a California resident, this is a free privacy win you shouldn't skip. If you're not, he covers what to do instead. Key Topics Covered: What DROP is — California's Delete Request and Opt-out Platform, and where the 614 data broker number comes fromHow it works — one free request, and what it actually deletes across registered brokersFiling it step by step — a few minutes of work, plus the scam to watch out forThe August 1, 2026 deadline — why that's the date brokers have to start honoring requestsThe honest limits — what DROP won't fix: Google, Meta, and brokers that re-collect your dataNot in California? — the moves that get you similar protection without DROP Main Takeaways: DROP lets California residents delete themselves from every registered data broker (614 and counting) with a single free request — no per-broker opt-outsAugust 1, 2026 is the date that matters: that's when brokers must start honoring DROP deletion requestsIt's not a silver bullet — it won't remove you from Google or Meta, and brokers can re-collect your data over time, so treat it as maintenance, not a one-and-doneWatch for the scam: the only official place to file is the state's own site — don't pay a third party to do what's freeNot a California resident? Freeze your credit and use manual opt-outs or a removal service to get similar coverage Timestamps: [0:00] The 12-broker breaking point[1:10] What DROP is and where the 614 number comes from[2:05] How it works and what it actually deletes[3:40] Filing it step by step, plus the scam to avoid[4:46] Why August 1, 2026 is the deadline[5:19] The honest limits: Google, Meta, and recurring brokers[6:51] Not in California?

    Ep43: The Best Personality Traits for Working in Cybersecurity

    Episode Summary: A Reddit thread on r/cybersecurity asked a simple question: what's the best personality trait for working in cyber? The answers — with hundreds of upvotes — weren't about hacking or certifications. They were about curiosity, patience, humility, staying calm under pressure, and empathy. Marc walks through each trait with personal stories from 8+ years of building teams, hiring, and working incidents at 2 AM. Key Topics Covered: Curiosity — the #1 answer by a wide margin; the trait that makes you dig into a log line everyone else shrugs offPatience — explaining technical risk to non-technical people without making them feel stupid, because if you do, they stop reporting incidentsHumility — saying "I don't know, but I'll figure it out" beats bluffing every time; ego is the worst trait in the fieldCalm under pressure — incident response at 2 AM, zero-days on Friday afternoons, breaches that keep growing; staying focused when everything is on fire matters more than any certEmpathy and kindness — cybersecurity is a people problem wrapped in a technology problem; being technically right doesn't matter if nobody wants to work with youThe uncomfortable truth — ADHD, burnout, trauma-induced hypervigilance; the always-on mindset is a strength until it isn't Main Takeaways: Technical skills are trainable — tools, frameworks, scripting languages, detection logic are all learnable, especially with AISoft traits like curiosity, patience, and empathy are harder to develop and are what separate people everyone wants on their team from people nobody wants to work withIf you're thinking about getting into cybersecurity, don't ask "am I technical enough?" — ask "am I curious enough to keep learning?"The best cybersecurity professionals aren't the ones who sprint the hardest — they're the ones still there in five years Timestamps: [0:00] Introduction — the Reddit thread that started it all[0:58] Curiosity — the #1 answer and why it matters[2:41] Patience — the art of explaining things without condescension[3:58] Humility — why "I don't know" is a superpower[5:15] Calm under pressure — the difference between a skill and a warning sign[6:28] Empathy and kindness — the most surprising and important trait[7:49] The uncomfortable part — burnout, ADHD, and mental health in cyber[9:11] Final thoughts — what really separates the best from the rest Tools & Resources Mentioned: Reddit Thread: Best Personality Type/Traits for Working in Cyber --- I do hope you enjoyed this episode of the podcast.
