Burp Suite is a Java-based, cross-platform penetration testing tool for web applications. It is widely used for intercepting, modifying, and replaying HTTP requests, supporting features like packet capture, manual request tampering, and brute-force attacks. However, when Burp Suite starts, it actively initiates DNSLOG probing. These automated requests can be flagged as suspicious activity by security infrastructure like STA (Security Traffic Analysis) probes or IDS/IPS systems.
