What is DNS Cache Poisoning?

DNS cache poisoning, also known as DNS spoofing, is a cyber attack that exploits vulnerabilities inDomain Name System (DNS) servers. By supplying your internet traffic with false information anddiverting it to fake servers, including your business server, it helps the attacker to poison the data onDNS servers. By redirecting the DNS data to their IP address, this is achieved.

The security flaws of DNS protocols are exploited by DNS cache poisoning to redirect internet trafficaway from legitimate servers to the wrong address.

For phishing attacks, also referred to as pharming, to spread malware, DNS cache poisoning iseffectively used. The malware runs and communicates with legitimate servers in the background tosteal confidential information.

When the DNS server is attacked, users may be requested to login into their accounts, and theattacker finds its way to steal the sensitive and financial credentials.

Moreover, phishing attacks also install viruses on the client's computer to exploit the stored data forlong term access.
