Elie Bursztein
Elie Bursztein (born 1980 in France) is a French computer scientist and software engineer. He currently leads Google’s Security and Anti-Abuse Research Team.

Education and early career 
Bursztein obtained a computer engineering degree from EPITA in 2004, a master’s degree in computer science from Paris Diderot University/ENS in 2005, and a PhD in computer science from École normale supérieure Paris-Saclay in 2008 with a dissertation titled Anticipation games: Game theory applied to network security.
His PhD advisor was Jean Goubault-Larrecq.

Before joining Google, Bursztein was a post-doctoral fellow at Stanford University's Security Laboratory,
where he collaborated with Dan Boneh and John Mitchell
on web security, game
security, and
applied cryptographic research.
His work at Stanford University included the first cryptanalysis of the inner
workings of Microsoft’s DPAPI (Data Protection Application Programming Interface), the
first evaluation of the effectiveness of private browsing,
and many advances to CAPTCHA security and usability.

Bursztein has discovered, reported, and helped fix hundreds of vulnerabilities, including securing Twitter’s frame-busting code, exploiting Microsoft's location service to track the position of mobile devices, and exploiting the lack of proper encryption in the Apple App Store to steal user passwords and install unwanted applications.

Career at Google 

Bursztein joined Google in 2012 as a research scientist.
He founded the Anti-Abuse Research Team in 2014 and became the lead of the Security and Anti-Abuse Research Team in 2017.
Bursztein's notable contributions at Google include:

 2020 Developing a deep-learning engine that helps to block malicious documents targeting Gmail users.
 2019 Developing a password-checking service that has allowed hundreds of millions of users to check whether their credentials have been stolen in a data breach while preserving their privacy.
 2019 Developing a Keras tuner that became the default  hypertuner for TensorFlow and TFX.
 2018 Conducting the first large-scale study on the illegal online distribution of child sexual abuse material in partnership with NCMEC.
 2017 Finding the 1st SHA-1 full collision.
 2015 Deprecating  security questions at Google after completing the first large in-the-wild study on the effectiveness of security questions, which showed that they were both insecure and had a very low recall rate.
 2014 Redesigning Google CAPTCHA to make it easier for humans, resulting in a 6.7% improvement in the pass rate.
 2013 Strengthening Google accounts protections against hijackers and fake accounts.

Trivia 
Bursztein is an accomplished magician and posted magic tricks weekly on Instagram during the 2019 pandemic.

In 2014, following his talk on hacking Hearthstone using machine learning, he decided not to make his prediction tool open source, because of the Hearthstone’s community disappointment and at Blizzard Entertainment’s request.
