Generated: 2026-07-05T02:25:43.709708+00:00
Latest MRT snapshot: 2026-07-04
Scope
For each AS_PATH observed in the daily RouteViews RIB, when the path's
destination prefix is European-allocated AND any AS in the path is
registered to RU or BY, we record (prefix, transit_asn) as an active
observation. When such an observation stops appearing in subsequent
snapshots it moves to history with a last_seen date.
Detects transit-MITM-class events. Origin-AS hijack detection is
in bgp_diversion_origin.md (Track A).
