The hacker behind TeamPCP was deanonymized and arrested. After a year of headline-making breaches and wild supply-chain attacks, taunting and teasing victims all the while... it turns out another kitty-cat profile picture was the thread that unraveled his identity.

"I Built an AI Cybersecurity Research Factory (for CTFs & Vulnerabilities)!" ... long-form video demonstration that doubles as "how I personally use AI lately," and some playground experiments setting it in motion to go hack away on wargames and potential software applications 🤖 Video link below:

During tax season I got a notification that my tax documents are ready, from... uh... Zoom 😂 Phishing email leveraging their legitimate document sharing functionality, pointing to a link and a domain that _looks like_ an IRS website, but, infects your computer. Video link: youtu.be/p6ySQ94GZsA

hELLO the tIME HAS cOME oNCE AGAIN on my cONTENT cALENDAR for me to continue to scream and shout about oUR VIRTUAL EVENT ContinuumCon 2026 jUNE 12 - 14 continuumcon.com livestream run of show is free & public but all workshop sessions get into hands-on labs see u there ✌️

A funny slew of phishing emails I've seen flying around: a legitimate Facebook Business invite notification, but bad actors stuffing threatening urgency into their "name" values that get inserted into the real email. And the phishing landing page is hysterical. 🤣 Video link: youtu.be/QRN3t1_paTY

Joined by Katrina Manson to hear all about her latest book release: Project Maven & the Dawn of AI Warfare 👀 We talk AI usage at the Pentagon, drone intel, AI enabled targeting, and the ethical tipping point of autonomous weapons. Super fascinating ideas. Video: youtu.be/OVgruylpVXc

Real treat to catch up with Joe Tidy and hear more behind the scenes deets about his book Ctrl+Alt+CHAOS: How Teenage Hackers Hijack the Internet 🤩 Insight into "the most hated hacker in history" and the rise and fall of teenage hacking gangs. Video: youtu.be/GUzD_ShRKYE

Fake Windows notifications -- homage to iPurpleTeam and their sweet recent writeup, showcasing some tricks with toast popups in pure PowerShell to fake alerts from installed apps found in Registry. Even a low-privilege custom protocol handler! Video: youtu.be/wrAFZLa1TAk

Our virtual event endeavor is back for its round-two show -- ContinuumCon 2026! Banner mantra "The cybersecurity conference that never ends" 😜 All sessions are workshops and you keep a whole cyber range to work on them whenever you want. jh.live/continuumcon Main eventlivestream is June 12-14th!

Vibecoding -- err... 🌈 AI assisted programming ✨ -- a "ChatGPT for the dark web!" Natural language chat interface backed by threat intel API, for a Golang tool with a TUI (in spirit of the current command-line coding harnesses 😜). Fun project. Video: youtu.be/oqU41QwtAGE

NahamSec teaches me bug bounty basics! He fills me in on the platforms, programs, and how the scope has grown so much now. Ben walked me through threat modeling and had a slick demo of his real-world bugs found with Red Bull and others 😎 Video: youtu.be/lNuvI48ysVo

GraphSpy: A Hacker's Tooling Deep Dive, video demos with the creator @RedByte1337! 🤩 Keanu shows me the wild things you can do for post-exploitation in Entra ID -- even adding a physical security key for persistence and a ton of other tricks 🤯 Video: youtu.be/qEtoKC32UoE

The recent Trezor-physical-mail-phish-delivery-crypto-scam made me giggle -- so I rambled about it in a video. I'm not a crypto guy but alarm bells should probably go off in your mind when something is asking for your recovery seed phrase. 😅 Video: youtu.be/UQFySFs2GJk

I've made some updates and added 2 hours worth of new material to the "Linux for Hackers Fundamentals" course on @hackinghub_io ! Vim text editor basics and sed & awk for text processing. Here's a 40% off discounted link if you'd like to take a peek :) hhub.io/Linux2026JH

h?ckers a[r]e gl*bbing! A little showcase of @0xv1nx0 's neat new project LOLGlobs -- demo is a teeny weeny PowerShell download cradle, obfuscated with globbing tricks and used with some 'living off trusted sites' just flair for funzies too :) Video: youtu.be/IImLVU39V_Q

Google API keys didn't use to be considered "secret," so they're all over the web-- but now they are an open door to Gemini 🫠 Quick rundown video of Truffle Security's really nifty research, almost 3,000 websites exposed.. including Google themselves😅 🔗 youtu.be/XNMHUifKce8

Quick dance with CVE-2026-21509, a "Security Feature Bypass Vulnerability" and an emergency out-of-band fix from January Patch Tuesday (and an obligatory exaggerated YouTube thumbnail -- I apologize and appreciate folks who understand algorithm nuance) youtu.be/Ck8IPInn74A

Moltbook is still weird. And external AI skills suck. I'm late to the yap party by a week or so (which is apparently an eternity in the current time vortex) but I wanted to show cool community resources & research amongst the skills shenanigans. Video: youtu.be/IvL89vbWmQ8

February got here fast-- and the 2026 Snyk Fetch the Flag CTF came up quick too! This year my friend NahamSec is hosting the game, starting NEXT THURSDAY 2/12 at 12pm ET! Free 24-hour Capture the Flag event with AR glasses as prizes 😎 See ya there! jh.live/snyk-ftf2026

Are MCP servers safe and secure? Yes? No? Sometimes? Maybe? ... Zack Korman shows me some of his learnings on MCP security (or lack thereof) with his "Evil MCP" project 😈 YouTube link: youtu.be/_r_sLetar_o 1. data exfil of your prompts & code context 2. inserting vulnerabilities into your code

I for one am totally guilty of just throwing caution to wind and poking at the newfangled whizbang AI world with reckless abandon -- but whatever "black box" we tout it to be, there's stuff you don't notice and forget that just you accepted the risk.

Also, meme thumbnail experiment continues. Disaster girl feels appropriate when AI might burn down your codebase. This is the first time Zack and I got to hang out and chat, please show him and his writeup some love! All credit to him and his work -- his blog: zkorman.com/posts/cyberd...

Video demo of the NTUSER dot MAN trick I saw floating around before the new year -- I did not know this was a thing👀 Hat tip to DeceptIQ et al.... we showcase: 1. breaking a Windows login with an empty user profile, 2. getting initial access EZPZ with a Sliver C2 implant,

I'm experimenting with MEMES in the THUMBNAIL and SHORT video TITLES to MITIGATE against CLICKBAIT Also experimenting with longer social text promos for video releases to add more preview details and context. I no longer have to just feed algorithms, but now LLMs, too!

Video demo of the NTUSER dot MAN trick I saw floating around before the new year -- I did not know this was a thing👀 Hat tip to DeceptIQ et al.... we showcase: 1. breaking a Windows login with an empty user profile, 2. getting initial access EZPZ with a Sliver C2 implant,

3. exporting, downloading, and hijacking an existing target user profile NTUSER.DAT or HKCU Registry hive, 4. converting hives from .reg plaintext to binary with the HiveSwarming.exe tool, 5. and establishing persistence with the new backdoored NTUSER dot MAN profile we upload!

No Registry writes, API calls or registry callbacks because it's just a single file placed on disk! Kinda neat. This is my first recording after a month break for the holidays and it was _painful_ -- lots of fails and mistakes and it took many hours 😅

"'ConsentFix', a browser-based ClickFix-style attack with OAuth consent grants" ... leveraging the Azure CLI app client to social engineer for easy access into Entra ID 👀 I got nerdsniped by this, so I played with it a bit and tried a drag-and-drop gesture! Video: youtu.be/AAiiIY-Soak

Infostealer malware logs -- maybe an unconventional threat intel source, but Estelle Ruellan shows me her sweet research using LLMs to analyze stealer logs at scale: - How did a victim get infected? - Can we uncover a threat actor when they infect themselves? and more. Video: youtu.be/3j4jzCU0Kwc
