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]
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.
The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans. [11] Snort can be configured in three main modes: 1. sniffer, 2. packet logger, and 3. network intrusion detection. [12]
In a May announcement, the U.S. Department of Health and Human Services said healthcare providers can ask UnitedHealth to notify people impacted by the hack on their behalf.
UnitedHealth Group said Monday that it’s paid out more than $2 billion to help health-care providers who have been affected by the cyberattack on subsidiary Change Healthcare.
The American Hospital Association (AHA) has advised health systems to disconnect from Change Healthcare and to create alternate plans in the event the attack continues for longer than expected.
This attack primarily centers on the largest 6,000 hospitals on a global basis. Healthcare data has the highest value of any stolen identity data, and given the weakness in the security infrastructure within the hospitals, this creates an accessible and highly valuable target for cyber thieves.
There are two types of shoulder-surfing attack: direct observation attacks, in which authentication information is obtained by a person who is directly monitoring the authentication sequence, and recording attacks, in which the authentication information is obtained by recording the authentication sequence for later analysis to open the device.
