Re: Faking the TCP handshake [New attack]
Eee, w czym problem? Przecie już od dawna się używa:
Kod:
# sysctl -a | grep timestamps net.ipv4.tcp_timestamps = 1
Nawet już na reddicie zauważyli dokument ([url=https://tools.ietf.org/html/rfc1948]May 1996, Defending Against Sequence Number Attacks (rfc1948)[/url])
Także w czym problem? xD
