The episode opens by thanking sponsors NDL Industries, Parker Sporlan, and Westermeyer Industries, then highlights NDL's CO₂-rated components including ball and check valves tested up to 2030 PSI with CE/CRN/UL certifications, high-pressure copper fittings rated to 1,885 PSI, and a CO₂ service tee. Parker Sporlan promotes its Virtual Engineer tool for sizing and selecting components for A2L refrigerant projects, and Westermeyer features RDP series differential pressure monitors for oil separator filter condition, including a transcritical CO₂ model. Brett and Kevin discuss actuator torque challenges on CO₂ valves under high differential pressure, ISO 5211 actuator mounting, and the tradeoff between leak-tight sealing and actuator size. They compare CO₂ adoption in the US (~5,000 systems) versus Europe (~95,000), discuss efficiency gains from improved controls, gas cooler sizing impacts, water restrictions affecting adiabatic cooling, ejectors, split gas coolers, and a Walgreens CO₂ rack using extensive heat reclaim, geothermal, and transcritical operation at about 90 bar.

A living off the land attack is one of the sneakiest techniques in a ransomware operator's playbook — and in this episode, Dr. Mike Saylor breaks down exactly what it is, how it works, and what your organization can actually do about it.Instead of bringing their own tools into your environment (which might trip your alarms), attackers just use what's already there. PowerShell. WMI. RDP. The same tools your admins run every single day. To your monitoring systems, it looks completely normal. That's the whole point.Mike and Curtis cover why attackers prefer your tools over their own, how recon can quietly run for 30 to 90 days before the attack goes loud, and what defenders can actually do about it — removing admin privileges, system hardening, golden images, application whitelisting, and free tools like Nmap and Wireshark. There's also a match.com story involving organized crime and a wooden casket on someone's front porch that you really don't want to miss.0:00 - Intro1:21 - Welcome and Book Announcement3:28 - What Is a Living Off the Land Attack?5:38 - Real-World Example: Conti Ransomware and WMI8:12 - Why Attackers Use Your Tools Instead of Their Own13:05 - Admin Privileges: Best Practice vs. Reality17:31 - The Louvre Heist Analogy20:08 - Recon Phase: Low and Slow24:16 - What Defenders Can Do25:55 - RDP and Remote Access29:48 - The Recon Timeline: 30-90 Days30:48 - PowerShell and System Hardening34:10 - Network Discovery Tools (Nmap and Wireshark)37:37 - Application Whitelisting and Geo IP Blocking42:08 - Action Items and Wrap-Up

What is an initial access broker — and why does it matter to your organization? In this episode, W. Curtis Preston and Prasanna Malaiyandi are joined by Dr. Mike Saylor of Black Swan Cybersecurity to break down the role of the initial access broker in today's ransomware attacks.Most people picture ransomware as a single bad guy with a keyboard. The reality is way scarier. There's an entire criminal supply chain out there, and the initial access broker is the specialist at the front of it. These are the people who do nothing but break in — stealing credentials, exploiting vulnerabilities, hijacking sessions — and then sell that access to other criminals who do the dirty work. Dr. Mike Saylor walks us through a real case study from 2024 where an employee's personal Gmail account — with a Google Docs folder literally named "passwords" — became the entry point for a corporate ransomware attack months later. This stuff is real, it's happening constantly, and most organizations have no idea how exposed they are.We cover what IABs target, how they package and sell access, what "coincidental passwords" are and why they're so dangerous, and what practical steps you can take today to make your organization a harder target.Chapters:00:00 - Intro: What Is an Initial Access Broker?02:12 - Welcome, Introductions, and a Little Judging03:33 - Defining the Initial Access Broker04:31 - Real Case Study: How Bob's Gmail Became a Corporate Breach07:16 - How IABs Package and Sell Access10:32 - How Stolen Credentials Get Bundled and Priced29:48 - RDP, VPN Vulnerabilities, and What IABs Are Hunting32:54 - Web Shells Explained35:08 - Session Hijacking and Man-in-the-Middle Attacks36:16 - Would Eliminating IABs Stop Ransomware?36:49 - How the Cybercriminal Ecosystem Evolved to Create IABs39:51 - Practical Takeaways: What You Can Do Right Now40:45 - The Numbers: 37 Billion Records and the ShinyHunters Breach
Inter Miami's attack wakes up in the second half as they comeback from a 2-0 deficit with 4 goals in the second half to get their first ever road win against Orlando City. Messi had a masterclass and plenty of other players performed at a high level. We go live after the match to break down what went wrong the first half and what change Mascherano made to flip the script in the second half.#InterMiami #messi #orlandocity #Intermiamicf

professorjrod@gmail.comAre you preparing for the CompTIA exam or looking to boost your IT skills development? This episode dives deep into Windows troubleshooting with a focus on network diagnostics — a crucial topic for any tech exam prep. We guide you through validating a Windows machine's network identity using IPConfig, performing a strict ping sequence to verify communication scope, and utilizing NSLookup to troubleshoot DNS issues. Following this disciplined order ensures clarity and efficiency, making every fix both defensible and effective. Whether you're studying solo or in a study group, this step-by-step approach to Windows networking will enhance your technology education and help you succeed in your IT certification journey.We dig into why a 169.254 APIPA address narrows the culprit to DHCP or network infrastructure, not the NIC or OS. Then we connect the dots between ports and services using Netstat, making it clear when a service is misconfigured rather than the network being “down.” From web ports 80 and 443 to SMB 445 and RDP 3389, you'll see how listening states reveal the true problem fast.Powerful remote access demands restraint. We break down when RDP makes sense, why Network Level Authentication should be non-negotiable, and how consent-based Remote Assist reduces risk when users need to stay in control. For scale, we highlight WinRM over HTTPS and SSH as secure, script-friendly options that keep credentials protected and GUIs out of the attack surface.Performance complaints need evidence, not guesswork. We show how Task Manager, Resource Monitor, Performance Monitor, and Event Viewer combine to reveal bottlenecks, crashes, and policy blocks. When things get critical—no boot, blue screens—we map BIOS vs UEFI realities, then use WinRE tools in the safest order to recover without data loss. By the end, you'll have a repeatable framework: identity, routing, names, services, performance, platform, recovery.
