Intercepting and Collecting Web Evidence in the Times of TLS1.3 and HTTP3.0

The presentation introduces methods for intercepting TLS/SSL connections. The focus is on man-in-the-middle attack employing proxy and other ways how to obtain unencrypted content of the TLS/SSL session. Speakers outline necessary theory (including news about TLS 1.3), well-known attacks (e.g., renegotiation, downgrade, cipherspec change, and others) and industry-standard tools (such as Wireshark, NetFox Detective, Fiddler Proxy and SSL-Split). The session also includes a live demonstration of the MitM attack on HTTPS connections enhanced with form-logging JavaScript injection. Participants will receive free of charge access to the testbed, which consists of real devices (and their traffic), including the prototype of our hardware probe decrypting SSL/TLS on-the-fly.
