Pharming

Pharming

Pharming is a type of cyber attack that redirects users to fraudulent websites or manipulates their computer systems to collect sensitive information. Unlike traditional phishing, which relies on deceptive emails, pharming uses malicious code executed on the victim’s device to redirect them to an attacker-controlled website. Here are some key points about pharming and examples:

1. How Pharming Works:

  • Malicious Code Execution: Attackers use malware (such as viruses, Trojans, or keyloggers) to execute pharming attacks.
  • Redirecting Traffic: The malware alters the victim’s DNS settings or modifies their hosts file, directing them to a counterfeit website.
  • Objective: Steal personal or financial information, such as login credentials, credit card details, or social security numbers.

2. Examples of Pharming:

        • DNS Cache Poisoning:
          • Attackers compromise DNS servers to redirect legitimate domain names to malicious IP addresses.
          • Example: Users trying to access their bank’s website are redirected to a fake site.
        • Hosts File Manipulation:
          • Malware modifies the hosts file on the victim’s computer, mapping legitimate domain names to malicious IP addresses.
          • Example: A user types “www.paypal.com” into their browser, but the hosts file sends them to a phishing site.
        • Router-Based Pharming:
          • Attackers compromise home routers to alter DNS settings for all connected devices.
          • Example: All devices in a household unknowingly visit counterfeit banking sites.

3. Preventing Pharming:

      • Keep Software Updated: Regularly update operating systems, browsers, and security software.
      • Use Secure DNS Services: Choose reputable DNS servers or use DNS-over-HTTPS (DoH) for encrypted DNS requests.
      • Monitor Network Traffic: Detect unusual DNS requests or unexpected redirects.
      • Be Cautious: Verify website URLs, especially when entering sensitive information.

4. Disrupting AI-Controlled Systems:

      • Description: Malicious AI could target critical infrastructure, financial systems, or communication networks.
      • Impact: System failures, economic losses, or compromised security.

Remember that pharming attacks can have serious consequences, so staying informed and vigilant is crucial for protecting your online security.
