Country-dependent analysis of the LinkedIn leak

Supervisor(s)Dr. Pascal Schöttle


In 2012 more than 160 million credentials (consisting of email address and password) were stolen from the business-oriented social networking site LinkedIn. Supposedly, the credentials belong to users from all over the world. At least it was reported that the leak contained more than 100.000 Austrian accounts.

The goal of this thesis is to analyze the LinkedIn leak separately for different countries and report differences in the distribution of common passwords among different countries. Furthermore, the thesis should give a statistical analysis about the gain of knowledge an attacker gets from knowing the home country of a potential victim.
