What's Your Mission? Start Ups, Soccer, and Selfishness.
Bubble Within Blocks Growing up as just another white kid from the suburban surroundings of Flint, Michigan I was pretty ignorant. Even though I lived ten minutes from the city of Flint, I couldn't have been farther away mentally. To me, Flint was the place...

No Thing Left Behind
You're Damn Right Adorable Crochet Puppy Mauls Researcher Most of what we've heard about the Internet of Things (IoT) has been pushing fear , uncertainty, and doubt with regard to security. But, the effect has not been an improvement of security! Rather, th...

A Final LZ4 Act - Hacking Erlang
Killing Money I've been getting a lot of emails, DMs, PMs, etc, congratulating me on my perseverance through the P.R. mess that has been the LZO/LZ4 bugs. Thanks for your support! But, let's be realistic, I've really just been killing money.  The amount of ...

So I Guess This Happened
LZO Exploit, You Say? What's that, you say? No functional exploits for LZO or LZ4? I guess both are proven, now. Sorry, folks, but we had to wait for a bit to let people get patched. We're kind to the Internet community like that.  In the next few days, we'...

The 42 Year Old Vulnerability
Two Deaths and Priceless Damage In 1933, the Castlewood Canyon Dam burst, causing a massive flood. Flood waters rushed from the dam 40 miles north to Denver, Colorado; an event that, according to the dam's chief engineer, could never happen.  The video blog...

I Was Wrong - Proving LZ4 Exploitable With Less Than 4MB
But Not In the Way You Might Think For the uninitiated, I recently uncovered a vulnerability in LZ4 during triage with the Linux kernel team on a separate but very similar issue in LZO. Ludwig Strigeus uncovered the issue over a year ago  and posted it to t...

The Internet of Us
It'll all be OK, little guy.  It's Not Me, It's You I've been analyzing and building Internet of Things technology since 2009. At the time, my wife Jessica and I were living in a condo building in Denver's Capitol Hill neighborhood. Nick DePetrillo and I ha...

Start-Ups, Information Security, and Budgets
Start Up, not Down.  The 80's Were Ok, I Guess As a child of the 80's, I was raised with a lot of mixed messages. These messages took a lot of bizarre forms. I distinctly remember Poison's "Open Up and Say Ahh" being re-released solely because parental grou...

Bla Bla LZ4, Bla Bla GoLang Or Whatever
I Was Coerced  A lot of people don't know this, but I've known Jaime Cochran  for almost fifteen years. We've been friends as long as I've been on the Internet. So, when she jabbed me earlier tonight saying "Hey, why the hell haven't you looked at GoLang ye...

The LZ4 Two Hour Challenge
I'm a Ruby Virgin So, I never found Ruby all that intriguing. It's just not that exciting to me. Sure, I can audit your Ruby on Rails app, but have I ever delved into the internals of Ruby to attack the language, itself? Nope. Not even remotely interested. ...

Hacking CERN - Exploiting python-lz4 for Particles and Profit
A Race Lost Before It Began Obviously the LZ4 issue has gotten a lot of attention, but unfortunately for the wrong reasons. A side effect of the negative reaction from the author of LZ4 is that some packages dependent on the compression algorithm thought th...

Understanding the LZ4 Memory Corruption Vulnerability
You Don't Play Right The entire premise behind security auditing is to identify ways that software can be abused. Period. Our concern as analysts is not to evaluate software "within the parameters in which it should be used". The best security bugs are slig...
