[bitcoin-dev] BGP hijacking on Bitcoin p2p network

[alicexbt]

Hi Bitcoin Developers,

Based on this [answer][1] from 2014, bitcoin nodes are vulnerable to BGP hijacking. There was an incident in March 2022, twitter prefix was hijacked and details are shared in 2 blog posts:

https://isc.sans.edu/diary/rss/28488

https://www.manrs.org/2022/03/lesson-learned-twitter-shored-up-its-routing-security/

'nusenu' had written an article about Tor network being vulnerable to BGP hijacking attacks: https://nusenu.medium.com/how-vulnerable-is-the-tor-network-to-bgp-hijacking-attacks-56d3b2ebfd92

After doing some research I found that RPKI ROA and BGP prefix length can help against BGP hijacking attacks. I checked BGP prefix length and RPKI ROA for first 10 IP addresses returned in `getnodeaddresses` in bitcoin core and it had vulnerable results.

Has anyone written a detailed blog post or research article like nusenu? If not I would be interested to write one in next couple of weeks?
Looking for some "technical" feedback, links if this was already discussed in past with some solutions.

Hi alicexbt,

Routing attacks have actually been studied quite a bit in literature.

You may be interested in the research articles of Maria Apostolaki et al.[1,2], Muoi Tran et al.[3], and related works.

Best,

Elias

Hi Elias,

Thanks for sharing the links.

I have also started working on a simple chrome extension which connects to local bitcoin core and checks IP address of all peers for prefix length and other things. I would highlight peers with different colors based on certain things in this extension.
