(Headquarters: Minato-ku, Tokyo; Representative Director and President: Hiroyuki Iwai; Securities Code: 4166; hereinafter "Cacco"), which supports the safety of online transactions with AI and proprietary algorithms, conducted the "2026 Survey on Internet Ad Fraud" targeting 400 professionals involved in web advertising operations.
