MITM Detector nga Stan Wijckmans

MITM Detector inspects the certificate chain of every HTTPS connection and cross-references the issuing certificate authority against a blacklist of known or suspicious issuers. When a suspicious issuer is detected, the extension displays a notification alerting the user to a potential interception attack.

A certificate issuer can be added to the blacklist by adding its Distinguished Name (DN) to the list on the extension's settings page.
