Cybersecurity researchers are warning about services that are being sold to bypass systems designed to distinguish between real users and automated bot traffic. These services are intended to circumvent CAPTCHAs (Completely Automated Public Turing test to tell Computers and Humans Apart), which are used to prevent spam and fake account creation. They work by sending requests to human solvers who figure out the solution and submit the results back to the users. Threat actors have been observed using these services in combination with proxyware to hide their IP address and get around antibot barriers. This makes it difficult for online web services to block abusers’ originating IPs. To combat this, researchers suggest that online web services should supplement CAPTCHAs and IP blocklisting with other anti-abuse tools.
