This TCP session hijacking technique might be of interest to some of you.

The paper demonstrates how traffic load of a shared packet queue can
be exploited as a side channel through which protected information
leaks to an off-path attacker. The attacker sends to a victim a
sequence of identical spoofed segments. The victim responds to each
segment in the sequence (the sequence is reflected by the victim) if
the segments satisfy a certain condition tested by the attacker. The
responses do not reach the attacker directly, but induce extra load on
a routing queue shared between the victim and the attacker. Increased
processing time of packets traversing the queue reveal that the tested
condition was true. The paper concentrates on the TCP, but the
