FreeBSD : tor -- diffie-hellman handshake flaw (5fde5c30-0f4e-11da-bc01-000e0c2e438a)

A tor advisory reports Tor clients can completely loose anonymity, confidentiality, and data integrity if the first Tor server in their path is malicious. Specifically, if the Tor client chooses a malicious Tor server for her first hop in the circuit, that server can learn all the keys she...

To shadowless go without a trace anonymous breakthrough network limit-vulnerability warning-the black bar safety net

Network management as the name suggests, is every pipe of the network, and tried various means to restrict our Internet access people. In the network established all sorts of rules, don't download, don't use IM, not allowed to access the restricted site, etc., so we can't enjoy the Internet bring...
