Connect The Dots: The Network Path – Part 2 of 2
In Part 1 of this topic, we saw how the so-called “Contact Path”—branches of investigation that stem from the registrant contact information in a Whois record—can often lead to the identity of a person or organization of interest. But sometimes the contact information is either fully privacy-guarded or is false data that leads to dea... - Wednesday, February 19, 2014 - 16:7
Connecting the Dots: Profoundly Important, Curiously Satisfying! Part 1 of 2
If economics and markets reflect what’s important to people–and, almost by definition, they do–then the practically eternal markets for games, puzzles, and reading material testify to deep human passions for solving problems and gaining knowledge.

Bitsquatting Is Alive and Well
Reading the recently released Cisco Annual Security Report, I paused on page 50 where the author talks about bitsquatting.  It seems this topic continues to ruminate in cybersecurity circles, recalling this paper from Black Hat in 2011.  So we spent a few hours yesterday poking around to examine some registration patterns related to ... - Friday, January 24, 2014 - 14:2

Whois and why is it suspended?
Answer: a (legal in the UK) betting site apparently owned by BSkyB that is temporarily suspended as a result of ICANN’s new Registrar agreement.

Knowledge Is (Fire)power!
Remember when there used to be a debate about whether or when full-on cyberwarfare would be upon us? It’s safe to say that the debate is over, or at the very least that it has morphed into a more nuanced debate about what to do about it.
