Bad bots interact with applications in the same way a legitimate user would, making them harder to detect and prevent. They enable high-speed abuse, misuse, and attacks on websites, mobile apps, and APIs. They allow bot operators, attackers, unsavory competitors, and fraudsters to perform a wide array of malicious activities. Such activities include web scraping, competitive data mining, personal and financial data harvesting, brute-force login, digital ad fraud, spam, transaction fraud, and more. Produced by the Imperva Research Labs, a premier research organization for security analysis, vulnerability discovery, and compliance expertise, the 2020 Bad Bot Report underscores the increasing pervasiveness of bad bots, revealing that no industry is safe from malicious bot activity.
