The Internet is a complex web of thousands of independently-managed networks organized into Autonomous Systems (AS). Border Gateway Protocol (BGP) is the protocol that all these Autonomous Systems use to share routing information with each other. Understanding BGP routing is the key to understanding how your network connects to the…
How does one steal crypto-coins? By hacking DNS and BGP – the two cornerstone protocols governing the Internet. With any cryptographic system, one way to compromise it is to be a man in the middle (MITM) when a transaction is taking place. Both ends of the transaction believe they’re talking…
In past blogs, we’ve explored how you can alert for and diagnose BGP route leaks and hijacks. Route leaks and hijacks—routing events where illegitimate prefixes are wrongly propagated through the Internet—are notoriously difficult to troubleshoot and have the potential to bring down entire swaths of the Internet.
In past blogs, we’ve explored a specific BGP issue that can have far-reaching, large-scale impacts on networks across the Internet: route leaks and hijackings. In this post, we’ll discuss alerting for leaks and hijacks, which is the first step in the process of detecting, diagnosing and ultimately mitigating these notoriously…
There have been a number of high profile routing leaks in the past few weeks. So today we’re going to review several of these leaks in detail to understand how the work, how you can detect them and how you can determine their severity. Our examples cover the Google /…
