Based on 987 announced prefixes, updated daily (2026-10-21). How the score works · RPKI explained
Listed on the threat map (2026-10-21)
- #28 of the 50 networks with the most flagged IPs worldwide (89 flagged networks)
- #2 in Pakistan (89 flagged networks located there)
- #10 for other malicious networks (39 flagged networks)
Large hosting providers appear because attackers rent their servers, not necessarily because of the operator.
