Network hijacking - the low down

This report summarizes network hijacking techniques — including rogue ASN announcements by unscrupulous ISPs, abuse of IXP peering to announce hijacked ranges directly, and BGP route hijacking (e.g., announcing more-specific prefixes) — and explains how these methods can be used to redirect or intercept traffic for credential theft, man-in-the-middle attacks, or infrastructure abuse; it points readers to a follow-up post for mitigation advice.
