In recent years, domestic Internet traffic from the United States and other countries has been misdirected via China Telecom, according to Oracle. The US Naval War College recently released a report claiming that China Telecom was deliberately manipulating BGP routing to intercept Internet traffic (pdf).
The term BGP refers to the Border Gateway protocol and allows traffic between different Internet providers. route. A network can advertise via BGP that it manages a particular IP block, so that other networks know where to send the traffic for that network. However, because of the complexity of the BGP configuration, errors can occur, which creates opportunities for traffic diversion, according to the Naval War College.
When the network 1 advertises via BGP that it manages an ip block that actually manages the network 2 Indeed, some of the traffic destined for the network 2 will be routed via the network 1. The execution of the diversion Because of the complexity of BGP, most of these attacks are committed by government agencies or large international criminal organizations with access to multiple ISPs placed at strategic locations, according to the report.
According to the Naval War College. China Telecom, which is owned by the Chinese state, regularly uses BGP diversion to intercept inter alia domestic Internet traffic from the United States. As a result of this report, Doug Madory of Oracle wrote a blog stating that China Telecom had indeed received domestic Internet traffic from the United States. Madory remains in the middle, however, deliberately or accidentally. In addition, he argues in favor of the introduction of certain mechanisms to prevent bad routing of traffic.
