Research undertaken between 2008 and 2014 suggests that more than 81% of Tor clients can be ‘de-anonymised’ – their originating IP addresses revealed – by exploiting the ‘Netflow’ technology that Cisco has built into its router protocols, and similar traffic analysis software running by default in the hardware of other manufacturers.
Professor Sambuddho Chakravarty, a former researcher at Columbia University’s Network Security Lab and now researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology in Delhi, has co-published a series of papers over the last six years outlining the attack vector, and claims a 100% ‘decloaking’ success rate under laboratory conditions, and 81.4% in the actual wilds of the Tor network.
