The Identity Leak Checker (ILC) is one of the oldest and probably best known research projects of the Security Engineering Group. On the Internet, digital identities are stolen, misused and resold by cyber criminals every day. Such identity data sets are used on the Internet to collect more and more information about users. Complete data sets can be resold more expensively, or used to improve future attacks.
With the ILC, we provide an infrastructure to collect and make available this identity data that is stolen from service providers and then published ("leaked"). You can therefore request a check of the leaked data for your e-mail address at the ILC. Upon verification, you will receive an email from us stating what types of data, such as username, password, or address and credit card information, are contained in the publicly available records. Based on this, you can take appropriate precautions and, for example, update your passwords.
On the website of the ILC you will also find some hints on how to handle accounts and passwords
