Study says malicious ISP can intercept information
Their submission is based on two identified characteristics that may make it relatively easy for a malicious Internet Service provider ISP to intercept a lot of Bitcoin traffic.
Routing attacks on Bitcoin
To start with, most Bitcoin nodes are hosted in few ISPs – 13 ISPs (0.026 percent of all ISPs) host 30 percent of the entire Bitcoin network.
Secondly, most of the traffic exchanged between Bitcoin nodes traverse few ISPs and three ISPs can see 60 percent of all Bitcoin traffic.
Bitcoin constitutes a target of choice for attackers already but while many attack vectors have already been uncovered.
Impact on the Bitcoin ecosystem
One of the reasons why routing attacks have been overlooked in Bitcoin is that they are often considered too challenging to be practical.
