10 years ago today, I built a cathode ray tube in a wine bottle for fun. I had been reading Linus Pauling's amazing textbook General Chemistry and realized that CRTs sat at an essential moment in physics history. In the late 1800s, high voltage and vacuum pump technologies were…
🔥 Microsoft patched a perfect 10.0 CVE in Entra ID (ex-Azure AD) that let attackers impersonate any user, even Global Admins—across every tenant worldwide. 🔑 MFA? Conditional Access? Logging? All bypassed. Total tenant takeover—SharePoint, Exchange, Azure resources. Details…
The Secret Service dismantled a network of more than 300 SIM servers and 100,000 SIM cards in the New York-area that were capable of crippling telecom systems and carrying out anonymous telephonic attacks, disrupting the threat before world leaders arrived for the UN General…
Europe might finally scrap the cookie banners they foisted on the entire world Trillions of wasted clicks and they actually make us LESS safe. Killing the dumb regulation would be a huge online quality-of-life upgrade.
