ACE Seminar: An Internet Census Taken by an Illegal Botnet

Speaker: Dr Oliver Hohlfeld

Date/Time: 20-Aug-2015, 15:00 UTC

Venue: Roberts 421



On March 17, 2013, an Internet census data set and an accompanying
report were released by an anonymous author or group of authors. It
created an immediate media buzz, mainly because of the unorthodox and
unethical data collection methodology (i.e., exploiting default
passwords to form the Carna botnet), but also because of the alleged
unprecedented large scale of this census (even though legitimate census
studies of similar and even larger sizes have been performed in the
past). Given the unknown source of this released data set, little is
known about it. For example, can it be ruled out that the data is faked?
Or if it is indeed real, what is the quality of the released data?


Oliver is heading the Network Architectures group within the
Communication and Distributed Systems (COMSYS) institute at RWTH Aachen
University. He obtained his PhD from TU Berlin in 2013. His research
interests include large scale internet measurement, network
architectures such as SDN, and the subjective evaluation of networked systems.
