There's also a fair amount of scraping for things like... - Reselling aggregated data - Competitive pricing and inventory data - "Sniping", like with auctions, event tickets, or things like airline check-in processes that are first-come, first-serve - Weird SEO stuff where people scrape content in the hopes that isn't indexed yet, and they can beat you to it. - And, sort of in the space you mentioned, searching for existing vulnerabilities by various signatures, or trying to brute-force guess things like passwords.
