Lcamtuf notably found several ELF Parsing bugs in file, that appeared may have been exploitable. The work he has been doing with AFL and googles big fuzz farm, focusing on utilitie…

The first way I did it was just read the file, parse the json, check for nulls, and print. Then I piped this to a file. That is too boring though. The next way I did it was with Vi…

It might be extremely valuable for Google to prompt you, while riding in your driverless Tesla, to make a stop at a Krispie Kreme on your way home.

What if you are an experienced engineer talking to another experienced engineer ? Seems to me if someone writes bad code when they SHOULD be writing good code, code-shaming might b…

Nginx and net/http has worked wonderfully for me. Nothing fancy is necessary.

After reviewing the code it looks like I was wrong. The code from the tutorial won't provide any encryption for your sessions, only integrity. In order to encrypt the values in the…

I actually wrote a tool[0] to attack gorilla sessions that are mentioned at the bottom of this, and gave a talk on some security functions in Go. The big take-aways from my talk. G…

They are technical. Brushing up on: K&R - The C Programming Language K&P - The Unix Programming Environment K&P - The Practice of Programming Kerrisk - The Linux Programming Interf…

Google has a big fuzz-farm and Project Zero looking for this type of thing and even they did not find Heartbleed years ago. They are nabbing tons of bugs but there are many that ar…

The new stuff happening in the PHP space is really really awesome. HHVM + HACK + XHP is an entirely different experience compared to writing PHP. Code can actually be very clean an…

Sounds like we were always on the same page... I never said an attacker can't do this. I'm saying an attacker can't do a s/https/http and have a user end up at an HTTP login page, …

Relay what credentials from the HTTP connection ? There are none... It sounds like you are talking about creating a phishing page and injecting it, hoping the user enters their cre…

Not all traffic. Amazon has a separate SecureOnly cookie for access to their trusted pages that isn't sent over HTTP. Without that cookie not all traffic can be proxied.

Right, but you get a redirect to the https login page with an http login URL. An attacker can attempt phishing with HTML/JS injection on a HTTP page but an attacker cannot get a us…

No. SSL stripping is an attack where you prevent a user from upgrading to an HTTPS connection. That isn't possible here. Many sites have multiple tiers of authentication. For examp…

What's wrong with being more than one thing. They are shaking up A LOT about how we currently think about the ``energy'' models. I think batteries are going to do wonder for countr…

I think it would be hilarious to see fictional "failed" historic YC apps, especially those that made it big in their time.

I don't understand your issue with hardcoded salts. It essentially works the same way as an HMAC. It is some secret material that further complicates the attackers job...It doesn't…

I actually think Terry could provide a lot of value if he was able to provide training in system engineering. The experience he has is invaluable. I'm not sure what his plan is, th…

In case you're thinking this is THE BUG that should have been released today, I don't think it is. While serious, I saw this on github several days ago. I've also seen two others t…

Would a possible example of a large magnitude event be the 2012 Virginia Derecho[1] ? Does anyone remember this evening as a day of large outages? I wasn't able to experience the e…

Yeah, it is only base64ing the woffs. The reason I post it is that it has all the benefits of this project (only CSS) without the downsides (being ridiculously hard to use).
