There is actually some good thinking going on out there. I saw it recently in the Albuquerque Journal, in an editorial piece by Tim Sarmo and George Orbanek, at this address: https://www.abqjournal.com/2491933/7-steps-to-better-government.html Such ideas. Consider: “We believe fact, supported by irrefutable evidence.” Not long ago I tried to point to that irrefutable evidence, in that …

Https://tls.ulfheim.net/ has a beautiful graphical way to see every step of setting up a TLS connection. This is porn for network geeks, but also for hackers (sometimes the same people). To paraphrase Ultra Famous Hacking God Pablos Holman, Here’s the messages between website and client to set up TLS. Every one of these is an …

The KBID XXX – TLS Downgrade I almost every course I teach I discuss the perils of “TLS fallback,” a fatal misconfiguration that negotiates a web server back to an old, insecure SSL/TLS version. From there it’s simple to use known exploits against the web server and boom, now it’s a Russian crimeware server. This …

A fellow teacher tells me about the “Holy Unblocker,” a proxy service that lets school kids get around their school’s web restrictions. It looks to me like it could be useful for other people, perhaps people living under regimes that want to control their access to knowledge and communications. This proxy is insidious: it uses …

Here’s an awesome Bluetooth exploit from 2018 that EVERY device was vulnerable to, called the KNOB attack. “We found and exploited a severe vulnerability in the Bluetooth specification that allows an attacker to break the security mechanisms of Bluetooth for any standard-compliant device. As a result, an attacker is able to the listen, or change …

Here’s another Google Appspot pen-testing practice site, this one focused on XSS (Cross-Site Scripting). Oh, it’s so fun to have sites where you can rampage like Hannibal’s elephants without getting condemned to death by gladiator! “In this training program, you will learn to find and exploit XSS bugs. You’ll use this knowledge to confuse and …

I’ll let them say it: “This codelab is built around Gruyere /ɡruːˈjɛər/ – a small, cheesy web application that allows its users to publish snippets of text and store assorted files. ‘Unfortunately,’ Gruyere has multiple security bugs ranging from cross-site scripting and cross-site request forgery, to information disclosure, denial of service, and remote code execution. …
