Passive DNS is not a new technique but, for the last months, there was more and more noise around it. Passive DNS is a technique used to record all resolution requests performed by DNS resolvers (bigger they are, bigger they will collect) and then allow to search for historical data.
When you are performing penetration tests for your customers, you need to build your personal arsenal. Tools, pieces of hardware and software are collected here and there depending on your engagements to increase your toolbox. To perform Wireless intrusion tests, I’m a big fan of the WiFi Pineapple. I’ve one for
I published the following diary on isc.sans.org: “SNMP Pwn3ge“. Sometimes getting access to company assets is very complicated. Sometimes it is much easier (read: too easy) than expected.

“Footprinting” is a technique to gather information about information systems. The goal is to collect as much information as possible and correlate them to build some kind of “business card” of the target. Relevant information are: DNS names, network topologies, software versions, localization and much more. To achieve footprinting, lot
