BGP hijack of Twitter by Russian ISP

March 30, 2022
On 28 March 2022, we reported about a BGP hijack of Twitter by a Russian ISP.

From 12:05-12:50 UTC, Russian ISP RTComm (AS8342) hijacked a prefix (104.244.42.0/24) belonging to Twitter. Thankfully, the hijack didn’t propagate far due to a RPKI ROA which asserted AS13414 was the rightful origin.

It’s worth noting that this is the same prefix hijacked during the coup in Myanmar last year. This is probably just reflective of the fact that this prefix is a common target for censorship. In both BGP hijack instances, the objective was likely to blackhole traffic but the route temporarily leaked out of the country.

Our report was highlighted in stories by Ars Technica, ITNews, a tweet by the CISO of Twitter and finally in an excellent blog post by Aftab Siddiqui of MANRS.
