Methods of counteraction of bypassing two-factor authentication using reverse proxy

The existing solutions for counteracting and preventing the interception of data tokens two-factor authentication are considered. Features that may indicate presence a silent reverse proxy server chosen. It is proposed to analyze information about additional time anomalies, which usually created by server. advantage this approach characteristics generated on client-side, malicious cannot modify it. Machine learning methods were used detect implicit signs A new method detecting satisfies following conditions proposed: 1) human factor minimized, 2) use an individual user possible, 3) has acceptable impact performance can be in real-time.
