Worst Thing That Could Happen

Before I install any patch, I always open the patch notes and Ctrl-F for 'supervolcano', 'seagull', and 'garbage disposal', just to be safe.

Guess I should turn off auto-update.

If you're going to let it burn up, make sure it happens over the deep end of the bathtub and not any populated parts of the house!

Why can't gravity work like this? Although avoiding your personal satellite accidentally transferring to someone else's orbit might be difficult.

The AARP puts the average age of a first-time grandparent close to 50, and the CDC has some data. But I don't have first-parent age distributions for specific names, or generational first-child age correlations, so the dotted line is just a guess. Still, let's be honest: No further research is really *needed.*

The Newbie’s Guide To JTAG

1 Share

Do you even snarf?

If not, it might be because you haven’t mastered the basics of JTAG and learned how to dump, or snarf, the firmware of an embedded device. This JTAG primer will get you up to snuff on snarfing, and help you build your reverse engineering skills.

Whatever your motivation for diving into reverse engineering devices with microcontrollers, JTAG skills are a must, and [Sergio Prado]’s guide will get you going. He starts with a description and brief history of the Joint Test Action Group interface, from its humble beginnings as a PCB testing standard to the de facto standard for testing, debugging, and flashing firmware onto devices. He covers how to locate the JTAG pads – even when they’ve been purposely obfuscated – including the use of brute-force tools like the JTAGulator. Once you’ve got a connection, his tutorial helps you find the firmware in flash memory and snarf it up to a file for inspection, modification, or whatever else you have planned.

We always appreciate guides like these that cover the basics, since not everyone is in the same place in their hardware hacking journey. This puts us in the mood to crack something open and start looking for pins, if for no other reason than to get some practice.

Firefox turns on DNS encryption

1 Share

Firefox announced today that DNS over HTTPS will be on by default in new versions of its browser, adding an extra layer of security for people browsing the information superhighway.

Since our work on DoH began, many browsers have joined in announcing their plans to support DoH, and we’ve even seen major websites like Facebook move to support a more secure DNS. If you’re interested in exactly how DoH protects your browsing history, here’s an in-depth explainer by Lin Clark. We’re enabling DoH by default only in the US. If you’re outside of the US and would like to enable DoH, you’re welcome to do so by going to Settings, then General, then scroll down to Networking Settings and click the Settings button on the right. Here you can enable DNS over HTTPS by clicking, and a checkbox will appear. By default, this change will send your encrypted DNS requests to Cloudflare.

DNS is how web browsers look up the true address of domain names such as google.com or boingboing.net. HTTPS encrypts this lookup, preventing it from being snooped on by service providers. This limits one method of collecting data about what people do online: for users, it's an obvious benefit, but advertisers and cops are hopping mad. Read the rest
