Description Having access to an internal network can provide a wealth of information, if you know how to look for it. This course will teach you Sniffing and Spoofing techniques using Ettercap and TCPDump. Once a foothold is established within a network, the next logical step is to try and capture the traffic of other systems to help gather intelligence. Having access to an internal network can provide a wealth of information, if you know how to look for it. In this course, Sniffing and Spoofing with Kali Linux, you’ll learn to use network packet inspection to your advantage. First, you’ll explore the ability to sniff and look at network traffic by using Ettercap and TCPDump to create a MAC flood attack. Next, you’ll discover how to perform an ARP poisoning attack, which establishes you as the “man-in-the-middle”, spying on traffic between a target PC and the router. Finally, you can implement a DNS spoofing attack, which ultimately can easily help you establish an additional foothold and provide you with a great deal of information about our target. When you’re finished with this course, you’ll have the skills and knowledge to work with Ettercap and TCPDump, tools needed to perform sniffing and spoofing attacks as part of a penetration test.

The Windows registry editor allows specially crafted .reg filenames to spoof the default registry dialog warning box presented to an end user. This can potentially trick unsavvy users into choosing the wrong selection shown on the dialog box. Furthermore, we can deny the registry editor its ability to show the default secondary status dialog box (Win 10), thereby hiding the fact that our attack was successful. View the full article

This is possible! This does not happen, It looks like it's from that other person's E-Mail. Here is a short explanation of what Spoofing exactly means: Spoofing is the forging of features with the aim of temporarily assuming a false identity. This can for example be e-mail, website, IP address and biometric features. Email Spoofing: E-mail spoofing is a term used to describe fraudulent e-mail activities. These activities involve changing specific properties of the e-mail message, such as From (From), Return-Path (Sender) and Reply-To (Reply to). This makes it seem like the e-mail comes from another source. E-mail spoofing is a common technique for sending spam. There are also computer viruses that use e-mail spoofing to spread themselves. The virus uses a different address that it found on the infected computer as the sender. In some cases, the virus itself also creates an e-mail address. Yaha.E is not the first virus that falsifies the sender. The Klez.H virus even did so structurally and is therefore difficult to combat to date. People whose computer is infected can be difficult to be alerted because their email address is unknown to most recipients. Okay, how are we going to do this? This time we are just looking for a website that can do this for us, Go to www.google.com Here we type in: Email Spoofer We just grab the first one, In my case this is Emkei's Instant Mailer, I use this Self too. If you click on it, we will come here: Here we will fill in all information, I will briefly describe what I have entered here: From Name: This is the name of the so-called sender, This sees the recipient. From E-mail: This is the E-mail where the e-mail comes from, the recipient sees this. So you can also take another man's E-mail, for example. To: This is the E-mail where you send the e-mail to, This is the recipient. Subject: Here you indicate the subject / title Attachments: Here you can add Images Content type: Which type of text you want to use Text: The text you want to send Captcha: This is just a security, just fill it out. Is always different And then you press send !! And then there is this: Congratulations, you have successfully sent your fake E-mail !! I hope you have done something about this, some will already know this. But is it always fun for the one who did not know this yet, and maybe it was necessary? Tjauw luitjes, Have a nice day !!
