 So a handful of my tech friends have brought this up and it's yet another problem with BGP and I've actually done a video or two on this before and we're going to talk about it again because well the problem still persists and hopefully one day we'll have BGP fixed. So quick background BGP border gateway protocol is how the internet routes itself. So while we talk a lot on this channel about routing internally in a network and firewalls and things like that the rest of the world has a routing method as well. It's it obviously a much larger scale than just routing in your office but the concepts are still the same and the BGP protocol is the way we understand these routes. Now in the early days of the internet everything was trusting and everything was just wonderful big happy place of academic sharing knowledge so these protocols were implemented with that same no one will do anything nefarious or bad or you know break any of this. But there is this case here this is the recent one regarding Google's getting hijacked. But like I said this let's visualize this a little bit and this is the site I've talked about before and I used it in my video for how human error broke the internet on November 6 2017. Here we are in November of 2018 and well this time they hijacked Google and what this allows you is each company is assigned an AS number autonomous systems number. So Google's is AS 15169 I'll leave a link to this here actually I'll be doing directly here what you're looking at is a visualization or how BGP routes between all the different Google data centers nodes and everything that belongs to their autonomous system and how it touches other networks. Now this is where things get a little goofy there's just a lot of trust between companies like level three cogent and all the different places in between Hurricane Electric here and these nodes in this graph kind of scales the nodes based on number of interconnects between there is all the different ways that if one line breaks another one will back up that line for the data to pass. But of course there's kind of like we're looking for the straightest path so BGP can helps find the straightest path or it can also redirect and this goes back to what's happening over here we can see the straightest path somehow became China so Google right routed through China and came back over here. Now this is one of the reasons for the absolute importantness of everything being an SSL that way despite the traffic being routed from this it still is encrypted and as long as no one has the encryption keys we should be good to go. Now let's go a little bit further in history though and I'll leave these links to if you want to read these. So this is a hijacking the internet using a BGP man in a middle attack back at DEFCON 16 this was from 2012. Then we have the original AS707 incident and this was the original Florida man there's a whole case study on it and it has a Wikipedia page and I see the original Florida man because somehow a system in Florida somehow turned the internet into all slash 24 prefixes and broke the internet and many of you that are watching this may not even be old enough to remember this but I got an upgrade here to tell you I was on the internet back then and yeah the internet broke but we kind of dealt with things like that you know this is back in our earlier days of the internet that sometimes things just didn't work and there's not a lot of detail unfortunately because no one really knows they have a breakdown of the incident but no one really knows exactly what happened but it started with a Florida router so our original Florida man somehow broke that if you're not in the US look it up you'll get the joke so it's still a huge problem it's still there it's is it something to be concerned about yeah but you can't do a necessary lot about it it's more pressure for unless you happen to work at one of these big companies replacing the broken and old BGP trust system that we have and we've just seen this abused over and over again and misconfigured because most of the systems that run BGP are not easy and so I know they don't necessarily put the new guy on it but then if you don't change routes very often you kind of are the new guy because you don't have a lot of experience with it so you break things and this is back my human error one nothing malicious was done they just oops some BGP routes and broke them and we've seen this happen before it just drives you nuts because you know you can't get two sections of the internet uh it's happened to AWS it's happened to all of them they didn't go down the routing tables got messed up that connects the connection from you to them so I'll leave you with this so you can read into it and get a better understanding I love playing with this site because it lets you dig into connections between everything it's just kind of a fun visualization and when you take out the search I'll show you what it renders when you look at just how big and just how many routes there are yeah it's huge and these are just these are not all the computers online these are all BGP routes that are in here and it is it's a lot of we've really made a complicated machine with this internet and because of it it's um being able to drill into and look at each one of them you start to get an idea of the scale and the scope of getting all these individual companies to agree on how all the routing works and that's where the challenge is we need a better trust system for this Google's been working on some replacements for BGP for a long time it's just really hard to get everyone on the same page because they're kind of like well as long as we trust each other it works until it doesn't but then we fixed it within a few hours so it's really not a big deal right it's a matter of time these scenarios have been played out in there not really well I guess they could be considered more doomsday scenarios as our dependence on the internet increases but being off the internet for a day or two doesn't always no you seem like a bad thing you know I guess I could take a day off work because no internet we don't get to do as much so these are my thoughts on it I'll leave you all these links in the description below so you can use them for the reading on it and dig into it and be as scared as the rest of us that BGP is just still broken today in 2018 as it was back when the AS707 incident happened back in April of 1997 wow it's been a while anyways thanks share your thoughts below in you know if you can influence the change of BGP because you have a position that you can do that it's got to be done I don't know when it will happen maybe we'll be revisiting this video again because the next time BGP hijacks and makes a mess out
