The take-over of the RSA Conference website(see Krebs here for a nice summary) reminds us (as if it was needed) that is not the technology the weakest link (and even less cryptography as such), but us, humans. Two points should be stressed:

• if system are too complex (like in this case, the relations between content providers of online information) we are not up to the task of managing their complexity and we fail to adopt the needed security measures
• technology and technical security is best and most easily circumvented and avoided by exploiting the human factor: why deploy expensive and technologically complex malware when you can send an email (well-formed) to ask employees to provide their usernames and passwords to access even mission critical systems? Much easier, faster, less expensive and you are sure to get an obliging answer!
