BGP prefix hijack → traffic interception
From a compliant origin AS, announce a more-specific or origin-spoofed prefix belonging to the victim. Internet routing converges on the attacker AS; traffic for that prefix flows through attacker for inspection / DoS.
§ Context
Assumed environment: attacker controls (legitimately or via compromise) a BGP-speaking AS that peers with major transit. RPKI ROAs not enforced by most peers — common for many regional ISPs.

§ Frequently asked
- What is the "BGP prefix hijack → traffic interception" attack path?
- From a compliant origin AS, announce a more-specific or origin-spoofed prefix belonging to the victim. Internet routing converges on the attacker AS; traffic for that prefix flows through attacker for inspection / DoS. It chains 5 steps drawn from real-world offensive-security techniques.
- What starting position does this attack require?
- The first step is Control / compromise an AS (T1583) — a resource development primitive. Assumed environment: attacker controls (legitimately or via compromise) a BGP-speaking AS that peers with major transit.
- What is the final impact of this kill-chain?
- The final step lands on Announce more-specific victim prefix (NET-BGP-HIJACK), which falls under Lateral Movement. From here, an operator typically pivots into post-exploitation or maintains persistence.
- How can defenders detect or prevent this attack?
- Detection and prevention vary per step. Refer to each linked MITRE ATT&CK entry under "References" — every technique on that page lists defensive controls, detection telemetry, and known threat-actor usage.

Attacker on a transit network between mobile-core hops (or with compromised UPF). GTP-U packets are typically unfiltered between PEs; inject packets into subscriber bearers — credential capture, free-of-charge tunnels, downstream attacks.
