DFOH

A System to Detect Forged-Origin BGP Hijacks

We report all new AS links and highlight in red the suspicious ones. For each suspicious case, we indicate the confidence level: the higher the confidence level the higher the likelihood that the suspicious case is malicious (ten is the maximum confidence level).

We provide the data since January 2022 and up to yesterday. The suspicious cases detected during the last 24 hours are visible in the live page.

You can use the form below to filter cases by time, AS numbers, or other attributes. You can click on a row in the table to see more details about a particular case.

Default date is 2024-01-01.

Below, you can indicate which filters you want to apply on the reported cases.

We found 87 new AS links among which 14 are suspicious.
