What is a MITM Attack?

A Man-in-the-Middle (MITM) attack is a type of cybersecurity threat where an attacker secretly intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other.

Types of MITM Attacks

ARP Spoofing
Attacker sends falsified ARP messages to link their MAC address with a legitimate IP address on the network.
DNS Spoofing
Attacker alters DNS records to redirect traffic to malicious websites.
HTTPS Spoofing
Attacker presents a fake certificate to impersonate a secure website.
SSL Stripping
Attacker downgrades an HTTPS connection to HTTP to intercept data.
Wi-Fi Eavesdropping
Attacker intercepts data on an unsecured Wi-Fi network.

Preventing MITM Attacks

  • Use strong encryption protocols (e.g., HTTPS, SSL/TLS)
  • Implement certificate pinning in mobile apps
  • Use Virtual Private Networks (VPNs) when on public Wi-Fi
  • Enable DNS Security Extensions (DNSSEC)
  • Keep software and systems up-to-date
  • Use strong authentication methods
  • Educate users about the risks of public Wi-Fi and phishing attacks
  • Implement network segmentation and access controls

MITM Tools and Commands

Common tools used in MITM attacks and their usage (for educational purposes only)

  • Ettercap

    ARP spoofing attack

    ettercap -T -q -i eth0 -M arp:remote /192.168.1.1// /192.168.1.2-254//

  • Bettercap

    Network attacks and monitoring

    sudo bettercap -iface eth0

  • Wireshark

    Network traffic analysis

    wireshark -i eth0 -k

  • SSLstrip

    SSL stripping attack

    sslstrip -l 8080

  • Mitmproxy

    HTTP/HTTPS interception and modification

    mitmproxy -p 8080
