Blind vulnerabilities, which occur when an attacker receives no immediate feedback from a system, present unique challenges in cybersecurity. Detectify's scanner addresses these by employing methods like local systems analysis, time-based responses, and out-of-band detection. Local systems allow attackers to test vulnerabilities in a controlled environment without needing server feedback. Time-based detection involves manipulating server response times to infer vulnerabilities, though it's prone to false positives and can disrupt legitimate users. Out-of-band detection, preferred by Detectify, involves sending a unique ID to the server and waiting for an external request to confirm a successful exploit, minimizing false positives and allowing for more comprehensive data extraction. While blind vulnerabilities can be harder to detect, they do not diminish the potential impact, as they are variations of existing vulnerabilities, such as SQL injection or cross-site scripting (XSS). Detectify's automated web app scanner, which is available for a free trial, uses these sophisticated techniques to provide reliable results and enhance security against blind vulnerabilities.
