AS4788 Telecom Malaysia major route leak?

I see tons of bogus routes show up with AS4788 in the path, and at least AS3549 is acceping them. E.g. for the RIPE NCC (193.0.0.0/21): [BGP/170] 00:20:29, MED 1000, localpref 150 AS path: 3549 4788 12859 3333 I, validation-state: valid > to 64.210.69.85 via xe-1/1/0.0 Tore
