Pharming in cyber security is a type of attack where users are silently redirected from a real website to a fake one designed to steal login details, financial data, or other sensitive information. It can happen by tampering with DNS settings, DNS cache, or a victim’s device so the redirect happens automatically.

Quick Scoop

How it works

  • A criminal compromises a system or network lookup path.
  • When you try to visit a legitimate site, you get sent to a spoofed copy instead.
  • If you enter your credentials, the attacker captures them.

Why it is dangerous

  • It can look completely normal at first glance.
  • Victims may not realize anything is wrong until after data is stolen.
  • It often targets banks, payment sites, and other high-value services.

How to reduce risk

  • Check the URL carefully before signing in.
  • Use up-to-date security software and system patches.
  • Avoid suspicious networks and report strange redirects quickly.

Pharming vs phishing

Pharming and phishing both aim to steal information, but they work differently. Phishing tricks you into clicking a fake link or opening a fake message, while pharming quietly reroutes you even if you typed the correct address.

Example

If you type your bank’s real web address but a DNS attack sends you to a clone site that looks identical, that is pharming.
