Cache poisoning is a cyber attack where an attacker injects false information into a DNS server to mislead users to a malicious IP address. This manipulation causes users to be directed to harmful websites, making DNS cache poisoning a significant security threat.
Key Points:
- How Cache Poisoning Occurs: Attackers inject malicious IP addresses into DNS caches, diverting users to the wrong sites. The use of UDP instead of TCP in DNS communication makes it vulnerable to this attack.
- Risks of Cache Poisoning:
- Hindrance of Data Security and Updates: Incomplete security updates leave systems vulnerable to trojans and viruses.
- Malware Infection: Redirected IPs can install harmful viruses on user devices.
- Data Violation: Users unknowingly share sensitive data like passwords and credit card information with malicious sites.
Prevention:
- Avoid clicking unknown links.
- Use VPNs for end-to-end encryption.
- Regularly scan systems for malware.
- Flush DNS cache regularly to prevent attacks.
