I am a postdoctoral researcher at CISPA Helmholtz Center for Information Security.

I work with Prof. Thorsten Holz at SysSec Lab. I completed my Ph.D. at University of New Orleans under the supervision of Prof. Phani Vadrevu. My Ph.D. work primarily focused on areas of Phishing, Web Security Crawlers, Browser Fingerprinting, and building tools for large-scale measurement using honeypots.

My current goal as a postdoc researcher is to provide insights related to scams and attacks that are ongoing in the Cryptocurrency realm. By understanding such scams, the motive is to build a defense mechanism. I am currently working on the following themes -

1) Understanding the end-to-end scamming model in Cryptocurrency attacks
2) Creating a honeypot model that would automatically collect scamming accounts on social media
3) Unveiling fraud payment profile established by scammers as in-take for payment
