Opening remarks BSides Tallinn organizers

We will introduce the wonderful day ahead.

It was a dark day in October in Finland when psychotherapy clinic Vastaamo’s data breach became public. For the first time in history, a ransomer had turned his attention from blackmailing a company to private individuals, with a threat of publishing their sensitive information online unless a ransom was paid.

Laura Kankaala is an ethical hacker and Security Consultant at F-Secure and is widely recognised as an authority in the ethical hacker community with a deep knowledge across the security landscape. She was one of the people aiding victims of Vastaamo case together with her fellow security professionals at KyberVPK. Laura’s mission in life is to build trust in technology through security and make the internet a better place for all of us.

This talk will cover the basic knowledge needed to start researching vulnerabilities in Windows drivers and author will also make publicly available a new tool that can easily be used for such ends.

Jaanus Kääp has worked in Clarified Security as a penetration tester and security researcher for the last 10 years. He has been in MSRC top security researchers list in 2015-2020; has published over 100 CVE-s, mostly by Microsoft and Adobe; found web vulnerabilities from Facebook, Google, Apple, Adobe, Spotify, etc. Kääp holds a Masters degree in Cybersecurity.
