    #537: Best OSINT Tools 2026: What Pros Use Daily

    Are you ready to see the 7 digital investigation tools that completely changed how I look at the internet? In this video, I’m REVEALING a powerful stack of OSINT (Open Source Intelligence) and research tools that most people have zero clue exist. These are absolute game-changers. Subscribe for more cutting-edge tech and security tools: The internet is vast, but finding the right information, or knowing what information about you is out there, requires the right toolkit. I was genuinely shocked by the advanced capabilities of some of these applications. Whether you are a cybersecurity researcher, a journalist, a private investigator, or just someone who wants to master digital reconnaissance and protect their privacy, this list of 7 secret tools will upgrade your skillset immediately. We are breaking down tools for deep email searching, uncovering hidden data in PDFs, mapping global networks, and analyzing trends that standard search engines completely miss. // MJ Banias’ SOCIALS // LinkedIn: / mjbanias Cloak and Dagger Podcast (Spotify): https://open.spotify.com/show/6mT8zDM...

  3. #536: Inside the Cisco 8000: 100Tbps Capacity

    #536: Inside the Cisco 8000: 100Tbps Capacity

    Is this the most powerful network switch ever built? In this interview from Cisco Live, we look at the new generation of Cisco 8000 and Nexus switches capable of routing 100 Terabits per second. We break down why AI data centers are forced to move from air cooling to liquid cooling, and how a single switch chassis can now handle the equivalent mobile traffic of 100 million people. AI models are growing faster than the infrastructure can keep up. To solve this, the network switch had to evolve. In this video, I talk to Will from Cisco about the engineering challenges of building the "G300" generation of switches, hardware so dense that air cooling is no longer enough. We discuss the massive architectural shift occurring in data centers, where Liquid Cooled Switches are becoming the new standard to support 1.6T Ethernet ports and massive GPU clusters. Key Hardware Topics: • The 100 Terabit Chassis: How Cisco architecture handles massive throughput. • Liquid Cooling: Why switches are adopting "direct-to-chip" cooling just like gaming rigs. • Scale-Out Networking: How these switches manage congestion for AI training jobs (Job Completion Time). • Career Insights: Will manages 5,000 engineers and explains why understanding the physical layer and hardware constraints is a superpower for modern developers.

    #535: Encryption vs Hashing: What's the real difference?

    Big thank you to DeleteMe for sponsoring this video. Use my link http://joindeleteme.com/Bombal to receive a 20% discount or use the QR Code in the video. In this interview, David Bombal sits down with Dr. Mike Pound (Computerphile) to clear up one of the biggest crypto misconceptions on the Internet: hashing is not encryption, and hash functions are not reversible. In this video you’ll learn what a hash function actually does (a deterministic, fixed-length, “random-looking” summary of data) and why the whole point is that you cannot take a hash and reconstruct the original file. Dr Mike explains the key properties of secure hashing, including the avalanche effect (tiny input change, massive output change), and why older algorithms like MD5 and SHA-1 became unsafe due to collisions. We also cover what “collisions” really mean, why they must exist in theory (the pigeonhole principle) and why they can appear sooner than expected (the birthday paradox). Then we tackle the YouTube-comments classic: rainbow tables. If hashes are one-way, how do attackers “crack” passwords? The answer: they don’t reverse hashes. They guess passwords, hash them forward, and match the results. Mike breaks down how rainbow tables speed this up with precomputed hashes, and why salting makes those precomputations far less effective by forcing attackers to redo work per user. Finally, we zoom out into modern cryptography: why SHA-2 is widely used today, why SHA-3 exists as a structurally different backup option, what length extension attacks are, and what quantum computing changes (and doesn’t change) for hashing and encryption. We also touch on how hashes power digital signatures, file integrity checks (like verifying an ISO download), and why AES dominates symmetric encryption. // Mike's SOCIAL // X: / _mikepound // YouTube Video REFERENCE // SHA: Secure Hashing Algorithm: • SHA: Secure Hashing Algorithm - Computerphile Birthday Paradox: • Hash Collisions & The Birthday Paradox - C...
