Is the FSI innovation rush leaving your data and application security controls behind? At the same time, the attacker floods the real router with a DoS attack, slowing or disabling it for a moment enabling their packets to reach you before the router's do. He or she can just sit on the same network as you, and quietly slurp data. Read more A man-in-the-middle (MITM) attack occurs when someone sits between two computers (such as a laptop and remote server) and intercepts traffic. Doing so prevents the interception of site traffic and blocks the decryption of sensitive data, such as authentication tokens. The attacker again intercepts, deciphers the message using their private key, alters it, and re-enciphers it using the public key intercepted from your colleague who originally tried to send it to you. Evil Twin attacks mirror legitimate Wi-Fi access points but are entirely controlled by malicious actors, who can now monitor, collect, or manipulate all information the user sends. Cyber criminals can gain access to a user's device using one of the other MITM techniques to steal browser cookies and exploit the full potential of a MITM attack.
