When a packet sniffer is used in 'promiscuous mode' users can analyze network traffic regardless of its destination - like a fly on a wall watching office activity. While this empowers IT professionals to perform a quick and thorough diagnosis of network security, in the wrong hands, Wireshark...
With the development of encryption protocols, users and email providers were able to convert plaintext messages into ciphertext, preventing unauthorized parties from snooping or stealing data via a packet sniffer (a program designed to collect and analyze data transmitted over a network). However, wh...
What are network sniffers? Network sniffers is a tool that is used to monitor the real-time data flow across a network. A network sniffer could check for abnormal usage by individual nodes. This information could be used by network administrators to optimize the network. The tool can either...
When spelled with a lowercase “s,” the term “sniffer” indicates the use of a packet sniffing tool for either good or nefarious purposes. In the hands of authorized network administrators, a sniffer is employed to maintain the unimpeded flow of traffic through a network. Conversely, in the...
What is a VPN? VPN stands for Virtual Private Network. The purpose of a VPN is to provide you with security and privacy as you communicate over the internet. Here's the problem with the internet: it's inherently insecure. When the internet was first designed, the priori...
First, packet capture devices connect to the network and simply record all the data that is being transmitted or received on a physical or wireless network. NetFlow data, on the other hand, is typically collected by network switches or purpose-built probe appliances that in turn send data flow...
They are eavesdropping on all of the connections going over this insecure, wireless network. Within the hacker’s sheaf of evil-doings is something called a ‘packet sniffer’. A packet sniffer is network utility that analyses and may inject tasks into the data-stream travelling over the ...
Internet Protocol spoofing.Likeidentity theft, IP spoofing takes place when cybercriminals alter the sourceIP addressof a website, email address or device for the purpose of masking it. This dupes the users into believing that they are interacting with a legit source and the sensitive information...
If anything seems out of the ordinary, unexpected or out of character, do not click or open an attachment. Spoofing Even if it looks exactly like a site you’ve been to before, it might be a malicious duplicate – especially if you’ve clicked a link to get there. ...
Due to the nature of Internet protocols, much of the information sent to the Internet is publicly accessible. When you connect to a local area network (LAN), every other computer can see your data packets. When an attacker is on the same network as you, they can use a sniffer to read...
