On NTP Reflection DDoS: 1990s Strike Back?

February 18, 2014 Added by:Anton Chuvakin

Sure, I admire the ability of attackers to find all the opportunities for amplification DDoS.

Why the FCC Can't Actually Save Net Neutrality

January 27, 2014 Added by:Electronic Frontier Foundation

Some people have condemned last week’s court decision to reject the bulk of the Federal Communications Commission’s (FCC) Open Internet Order as a threat to Internet innovation and openness.
