What is a route leak in networking?
In: 3
When computers communicate to each other over the internet, they don’t send messages directly (as they are not directly connected), but the data is sent through a number of hops or intermediary hosts. (Called routers.)
Often, the complete patch from A to B has a number of internal hops and a lot of external ones.
If the internal hops/routers are visible, this is called a route leak, and attackers can use it to gain insight in the internal network to plan future attacks.
