Social engineering? Signing up for the listserv is a matter of going to this website., then filling out such hard hitting forms as "Name" and "Interest in Biometrics", and waiting for an e-mail confirmation stating you've been approved. Since the website says that its a free listserv for anyone interested in Biometrics, I don't think approval would be all that hard to get. After they signed up, they then summarized the most interesting things from each year that were posted to the listserv, and posted the results on the web. Wow! From the summary and translated article make it seem like they pulled a government approved hack of the NSA using cunning wit and unmatched skill or something.
