How do we explain email to an "expert"?

This has been a pretty wild week, more wild than usual I think we can all agree. The topic I found the most interesting wasn’t about one of the countless 0day flaws, it was a story from Slate titled: In Praise of the Private Email Server The TL;DR says running your own email server is aContinue reading “How do we explain email to an "expert"?”

The cost of mentoring, or why we need heroes

Earlier this week I had a chat with David A. Wheeler about mentoring. The conversation was fascinating and covered many things, but the topic of mentoring really got me thinking. David pointed out that nobody will mentor if they’re not getting paid. My first thought was that it can’t be true! But upon reflection, I’m pretty sureContinue reading “The cost of mentoring, or why we need heroes”

Can’t Trust This!

Last week saw a really interesting bug in TCP come to light. CVE-2016-5696 describes an issue in the way Linux deals with challenge ACKs defined in RFC 5961. The issue itself is really clever and interesting. It’s not exactly new but given the research was presented at USENIX, it suddenly got more attention from the press. The researchersContinue reading “Can’t Trust This!”

We’re figuring out the security problem (finally)

If you attended Black Hat last week, the single biggest message I kept hearing over and over again is that what we do today in the security industry isn’t working. They say the first step is admitting you have a problem (and we have a big one). Of course it’s easy to proclaim this, ifContinue reading “We’re figuring out the security problem (finally)”

Using a HooToo Nano as a magic VPN box

I’ve been getting myself ready for Blackhat. If you’re going you know this conference isn’t like most. You don’t bring your normal gear with you. You turn the tinfoil hat knob up to an 11, then keep turning it until it breaks off. I did do one thing that’s pretty clever this year though, IContinue reading “Using a HooToo Nano as a magic VPN box”

But I have work to do!

There’s a news story going around that talks about how horrible computer security tends to be in hospitals. This probably doesn’t surprise anyone who works in the security industry, security is often something that gets in the way, it’s not something that helps get work done. There are two really important lessons we should takeContinue reading “But I have work to do!”

Decentralized Security

If you’re a fan of the cryptocurrency projects, you’ve heard of something called Ethereum. It’s similar to bitcoin, but is a seperate coin. It’s been in the news lately due to an attack on the currency. Nobody is sure how this story will end at this point, there are a few possible options, none are good.Continue reading “Decentralized Security”
