Analyzing Pwned Passwords with Apache Spark

slides:none on file

Loads SHA-1 hashed breach records into Apache Spark via a Zeppelin notebook, infers schema from CSV/JSON, and joins with a 700k common-password list to produce counts and visualizations. Analysis shows obvious winners like "123456" seen >20 million times, length peaks at 6- and 8-character peaks, and a dog-name hit with Charlie: 278,000 matches. Uses DataFrame/Dataset APIs, UDFs and SQL DSL for filtering, and demonstrates practical ETL patterns and security takeaways (use password managers, prefer app-based 2FA).
