I read about this. Very interesting. Tor has obviously been cracked open by the NSA so this could be a disaster waiting to happen. Still most definitely very interesting to say the least.
HORNET, like Tor, is not immune to targeted attacks on anonymity. If an attacker, such as a government agency or law enforcement organization, could control more than one of the nodes along a path selected for a HORNET channel, they would be able to perform "confirmation attacks"—the sort of timing analysis, flow analysis, and packet tagging that other security researchers have demonstrated could be used against Tor. "HORNET cannot prevent such confirmation attacks targeting individual users," the researchers concluded. "However, HORNET raises the bar of deploying such attacks for secretive mass surveillance: the adversary must be capable of controlling a significant percentage of ISPs often residing in multiple geopolitical boundaries, not to mention keeping such massive activity confidential."
