Network eavesdropping, also known as eavesdropping attack, sniffing attack, or snooping attack, is a method that retrieves user information through the internet.This attack happens on electronic devices like computers and smartphones.
Despite being partially mitigated in 2010, history sniffing is still considered an unsolved problem. [8] In 2011, researchers at Carnegie Mellon University showed that while the defences proposed by Mozilla were sufficient to prevent most non-interactive attacks, such as those found by Jang et al., they were ineffective against interactive attacks.
This attack can be performed either at close range (by directly looking over the victim's shoulder) or from a longer range with, for example, a pair of binoculars or similar hardware. [3] Attackers do not need any technical skills in order to perform this method, and keen observation of victims' surroundings and the typing pattern is sufficient.
Methods to prevent session hijacking include: Encryption of the data traffic passed between the parties by using SSL/TLS; in particular the session key (though ideally all traffic for the entire session [21]). This technique is widely relied-upon by web-based banks and other e-commerce services, because it completely prevents sniffing-style ...
Sniffing attack in context of network security, corresponds to theft or interception of data by capturing the network traffic using a packet sniffer (an application aimed at capturing network packets). When data is transmitted across networks, if the data packets are not encrypted, the data within the network packet can be read using a sniffer. [1]
An attacker can reduce the "availability" of an IDS by overwhelming the human operator with an inordinate number of alerts by sending large amounts of "malicious" traffic intended to generate alerts on the IDS. The attacker can then perform the actual attack using the alert noise as cover. The tools 'stick' and 'snot' were designed for this ...

[2] [3] This paper caused some consternation in the security community, which had previously believed that such monitoring was a highly sophisticated attack available only to governments; van Eck successfully eavesdropped on a real system, at a range of hundreds of metres, using just $15 worth of equipment plus a television set.
