Hello everyone, We received a strange request that I wanted to share. An email was sent to us asking to confirm a LOA from a diligent ISP. The Loa was a request to open bgp for an AS , that is not ours, to announce a /23 prefix that is ours. So basically this entity sent to their upstream a request to announce a prefix from one our allocated ranges. We have the allocation correctly registered and ROAs in place , but it is worrisome that someone would attempt this. Obviously we have informed the ISP that the LOA is not valid and are trying to contact the originating party. Aside from RIRs for the offending AS and our IPs, Is there anywhere to report this type of activity? We have dealt with hijacking technically speaking in the past but this is the first time, to my knowledge, of someone forging a LOA with our IPs.
Thanks in advance for any advice Brian P.S. a big thanks to Chris for checking the boxes before activating the filter if you are on the list!
