Bypass Bot Detection

Summary: PortSwigger Research lists a Burp Suite extension, authored by Zakhar Fedotkin, that mutates ciphers to bypass TLS-fingerprint based bot detection. The extension changes network settings under Settings -> Network -> TLS to select "Use custom protocols and ciphers," modifies those settings during brute force attacks, and per its own listing cannot bypass aggressive bot detection.

What you should know: A tool that alters TLS fingerprints to slip past bot detection is available as a Burp extension, so controls that rely on TLS fingerprinting alone are being tested against a published bypass.
