![]() ![]() There are two primary sniffing attack types: passive and active. This allows the attacker to intercept and read all traffic passing between the two “devices.” Types of Sniffing Attacks This computer acts as a proxy between the targeted devices and the rest of the world, allowing the attacker to capture all traffic passing through.Īnother common technique is ARP poisoning, in which the attacker tricks devices on the network into thinking they are communicating with another device when they are not (Grimmick, 2021). One popular method is to set up a packet sniffer on a computer connected to the network in question. There are several ways an attacker can capture packets passing through a network. In some cases, attackers may also use sniffing attack tools and packet sniffers to inject malicious code into otherwise innocuous data packets in an attempt to hijack a target’s computer or other devices. ![]() Common targets for these attacks include unencrypted email messages, login credentials, and financial information. What Are Sniffing Attacks?Ī sniffing attack occurs when an attacker uses a packet sniffer to intercept and read sensitive data passing through a network (Biasco, 2021). This can be done using software that captures all data packets passing through a given network interface or by using hardware devices explicitly designed for this purpose. ![]() In its simplest form, sniffing is the act of intercepting and monitoring traffic on a network. This article will look at what sniffing is, how it can be used for harm, and how sniffing attacks can be prevented. However, when employed by malicious hackers, sniffing can be used to launch devastating attacks against unsuspecting targets. ![]() Ethical hackers can use sniffing to gain tremendous insights into the workings of a network and the behavior of its users, which can be used to improve an organization’s cybersecurity. The technique of capturing all data packets traveling through a network using a software application or hardware device is known as network sniffing (Mitchell, 2021).
