This is possible because a packet sniffer can analyze the conversation between two or more nodes in a network. So, in the event of a network error, the information captured by the packet sniffer can be used to identify the erroneous packets and pinpoint the node that failed to answer the request s.
Making it easy to identify faulty devices within the network in an efficient manner and providing the ability to take swift corrective actions. Detecting security loopholes — A disturbing fact about packet sniffers is their ability to work as spying tools. They also help the good guys, such as your Network Manager, by testing the vulnerabilities of a network. Once these vulnerabilities are detected, it is easier to remove the loopholes thus preventing the possibilities of hacking attempts.
IP sniffing and MAC sniffing are some of the most common ways to analyze and examine the traffic flowing through a network. Thus the network administrator can easily analyze the information packets to detect any flaws within the network. While Packet sniffers have legitimate uses in monitoring and troubleshooting a network, they have also been widely used by hackers for gaining unauthorized access to a network and stealing information. That is why it is very important for network managers to put security measures, such as firewalls, in place to prevent intrusion to the network.

It can be used for good, to run diagnostic tests and troubleshoot potential problems.
But it can also be used for malicious purposes, to snoop in on your private data exchanges. This includes: your web browsing history, your downloads, the people you send emails to, etc.
But how does a packer sniffer work? Simple — when data packets are transmitted, they pass through several nodes in a network. If a node finds the packet is addressed to some other node, it drops or ignores the packet. In packet sniffing, on the other hand, some nodes are programmed to not follow this practice and collect all or a certain sample of packets, regardless of their destination.
As mentioned before, a packet sniffer can have both positive and negative use cases, depending on who is using it. Cyber attackers can exfiltrate sensitive information from unencrypted messages.
If a user logs into websites over unencrypted transmission his credentials are exposed in plain text and can be easily intercepted by packet sniffers. Image Source: DNSstuff. Making sure all applications and servers within an organization run without any performance bottlenecks is a difficult task.
Digital lawbreakers utilize these as hacking devices to sniff, capture, and take private data, for example, client characters, passwords, login certifications, card subtleties, messages, texts, information, and furthermore for ridiculing information.
