I have been searching all over the place to find an answer to this question, but Google has made me feel unlucky these last few days. I hope I could find more expertise here. The burning question I have been pondering over is - could TCP connections be hijacked both ways?
Quick summary: Steve Bellovin pointed out the issue. 19<stone age> Kevin Mitnick exploited it. 19<bronze age> Steve wrote RFC1948, which basically said "Use randomized ISNs so the attacker has to work harder at it". 1996. A lot of vendors sort of implemented it. 1996-2000. Michael Zalewski did a nice phase-space analysis and showed a lot of vendors botched it. http://lcamtuf.coredump.cx/oldtcp/tcpseq.html 2000 A lot of vendors fixed their shit, but a lot didn't. http://lcamtuf.coredump.cx/newtcp/ 2001. You're now caught up to 6 years ago.
