Spider AF, a privately owned Japanese company founded in 2011, provides ad measurement and verification services. Employing approximately 50 people, the company's primary product is a tool designed to identify and prevent invalid clicks and conversions in online advertising, thus mitigating ad fraud. In 2023, the company's revenue was less than $1 million.
Ad fraud constitutes a significant financial threat, exceeding billions of dollars and impacting key performance indicators. A large portion of digital advertising spend, estimated at nearly 20%, fails to reach genuine customers due to fraudulent activities such as bot clicks, impression stuffing, and fake leads. Google Tag Manager (GTM), while beneficial for managing marketing tags and scripts, also presents a vulnerability due to its widespread use and potential for exploitation. Client-side security monitoring helps observe and analyze script behavior within users' browsers to detect malicious activity, including data access and interactions with external systems. The convenience of GTM, while improving workflows and saving time, also makes it a target for attacks.
