Book review: Silence on the wire
While looking for some interesting read for the summer, I’ve stumbled across a book written by Michal Zalewski named “Silence on the wire: a field guide to passive reconnaissance and indirect attacks”, from No Starch Press.
Passive fingerprinting and reconnaissance is a technique that bases all its findings on what the is received on the wire. No packets are generated at all, unlike more conventional scanning techniques (see nmap as an example of active scanning). But passive reconnaissance goes beyond the determination of the Operating System; sometimes valuable information is leaked, intentionally or unintentionally, in the packet.
