"Because cybercriminals are keen on breaking CAPTCHAs accurately, several services that are primarily geared toward this market demand have been created," Trend Micro said in a report published last week. Cybersecurity researchers are warning about CAPTCHA-breaking services that are being offered for sale to bypass systems designed to distinguish legitimate users from bot traffic.
