BGP hijacking is the fraudulent rerouting of internet traffic by taking over IP addresses.
BGP hijacking is a form of DDoS attack that may used to steal credentials from personal and financial accounts. This is done as a part of a man-in-the-middle attack that sniffs for information on networks. They could also complement advanced phishing attacks or be a part of a disinformation campaign.
An autonomous system refers to a network or a collection of network that a particular organization manages.
Signs to watch out for
External services can be employed to watch out for illegitimate announcements to the BGP router.
The hijack may result in a page loading multiple times because the network requests may be traveling a long path. Latency will also rise notably in most cases.
There are monitoring tools available that detect possible BGP hijacking attacks.
