Risky Business #386 — Katie Moussouris on the (groan) disclosure debate

On this week's show we're checking in with Katie Moussouris of HackerOne. She's an ex Microsoftie who's spent something like a decade working on vulnerability disclosure policies. She even helped get a vuln disclosure ISO standard ratified!

And she'll be joining us this week to discuss disclosure politics, I guess you'd call it... for those of us who've been around infosec for a while, most of us would rather stick our face in a blender than talk about it, but Katie will be along to point out why people should fight their "disclosure debate fatigue" and get involved.

The two countries have apparently agreed that they won't hack each other with the aim of stealing IP anymore. Questions to Richard include: Are they kidding?

Bridging Between Cisco VIRL and GNS3 for L2 and Serial Support

One of the known issue for anyone preparing for a Cisco exam is that the solutions available today don’t support all the needed features.  Cisco VIRL supports L2 switching out of the box, whereas GNS3 does not.  GNS3 supports the configuration of serial interfaces on routers whereas Cisco VIRL does not.  For someone starting out in this […]

An EIGRP Scaling Puzzle

This last week I received an email from a friend asking about scaling. The situation is this: a particular company has well over 100 EIGRP routers on a single L2 service from a provider. Will this scale? What’s more interesting than simply asking about scale, though, is to ask the “why” question — no matter […]

Risky Business #384 — Mark Dowd talks AirDrop pwnage, XCode iOS scandal

We've got a great show for you this week. Mark Dowd drops by to talk about the recent spate of Trojaned iOS apps that made it into Apple's China App Store. We also talk to him about his awesome AirDrop bug. How did it work?

This week's sponsor segment is actually a real cracker. Context IS consultant David Klein tells us how he owned an entire cloud platform by enumerating some shitty 90s-style bugs in some third party libraries they were using. It's comedy gold. This cloud platform that uses security at a selling point. It's bad.

HTIRW: The Internet Society

In ending this series — which I hope has been useful for Packet Pusher’s readers to get a solid survey of the entire Internet’s operational structure — we’ll talk about one of the “forgotten” groups of people helping to build and maintain the ‘net as we know it. Without this organization the Internet probably simply […]
