A senior security researcher at Census will cover the importance of domain impersonation, basics of BigQuery, Levenstein's distance, and URLs, and conduct a live demo. Domain impersonation occurs when a cyber criminal fakes a website name or an email to deceive users, leading to potential security risks. Organizations face challenges in protecting their users from domain impersonation attempts, and Census can help by quickly identifying potential threat actors and providing information for proactive blocking of impersonating domains. Fuzzy matching on the information collected by Census can be used to proactively block impersonators before they reach users, preventing organizational issues. The session will emphasize the importance of different URL components for obtaining different scores and encourage further investigation beyond the initial query results.
