Hi friends,
Tor
has always been a tough target for law enforcement for years and FBI
has spent millions of dollars to de-anonymize the identity of Tor users,
but a latest research suggests that more than 81% of Tor clients can be "de-anonymised" by exploiting the traffic analysis software ‘Netflow’ technology that Cisco has built into its router protocols.
NetFlow is a network protocol designed to collect and monitor
network traffic. It exchanged data in network flows, which can
correspond to TCP connections or other IP packets sharing common
characteristics, such UDP packets sharing source and destination IP
addresses, port numbers, and other information.
