@@natural......9963 It's automatic because I have a membership with David Bombal ($1.99/mo). It's like Patreon, but through KZbin. Other plans are available, each with specific perks.

When I thought about how much I spend on books (that take hour[s] to absorb) versus watching a 30-min video demo, the $2 seems a pittance.

Even his uplinks and downlinks entered in error-disable mode. There was upon a time when dot1x came out to play...

She was a drug addict, I realized a bit late through her text messages and recent call records to different hard drug dealers. She had gotten to the point of selling them for a living and I noticed she’s always spending lavishly and never thought of our kids and I thought that was enough until she brought a man to our bed while I was away to satisfy her sexual urge. I got all the information from her through the great service of *ONE HACkER WHITE on IG, WhatsApp [phone]‬* I won’t have known if I didn’t take this bold step.

Pretty useless video. you have root access to the switch

[@davidbombal]

I am teaching concepts in this video and have privilege 15 access (or root as you say) to demonstrate concepts. However, that level of access is not required to successfully launch a lot of the Yersinia hacks like CDP, VTP, STP or DHCP etc. These are layer 2 attacks that do not require any type of user authentication or authorization. Best practice would be to enable root guard, port security, dynamic ARP inspection, DHCP snooping and other mitigation techniques. The videos in this series teach why those types of protocols and mitigation techniques should be enabled.

@@davidbombal David Bombal my point is, you can confirm the attack is successful, how would an attacker know. And u know the switches setup with default config. Whether it be layer 1,2,3 core switch or even a layer 7 firewall you just flooding the switch with random traffic, which most Cisco's will disable that port and your "hacking" is being locally connected? . So the video then is mis titled hacking, I mean you could do the same with multiple computers doing a simple ping - l xxxxx. It's not hacking is all I'm saying, it's denial of service.

@@davidbombal also in your guide, maybe teach the guys su/sudo apt-get update/upgrade/install.

@@travismailsa1 When teaching concepts like these, I believe it is really important to demonstrate the results of the attacks. I would get a huge number of complaints if I didn't show the results of the attacks; and also set the foundation of what we are doing. This is also only one of the videos in the series and as I said in the video that it is getting too long, so I put more information in Part 2 and more in subsequent videos. I am showing attacks from the ground up - from initial installation in the first video in the series to more complex attacks. Probably best that we agree to disagree on this.

@@davidbombal I concur :) maybe change the video title, because that's why I came to watch. I thought it would of been a bug/firmware exploit or a Medusa or ripper attack from kali. Your video is well presented though. Finally :) if you teaching from the ground up and performing an "attack" locally advise on a Mac change.

Three guys just met eachother and they have a conversation about different sorts of paste😂😂😂 The first guy says: "I know everything about tomato paste, because I own an Italian restaurant." The second guy says: "I know everything about toothpaste, because I am a dentist." The third guy says: "I know everything about copy-paste, because I am a Redditor."😂😂😂😂😂😂😂😂😂😂😂😂 😂😂😂

Possibly the video is mirrored? I know some cameras do it by default as that's how you see yourself in the mirror.

Hi there. Im totally new to kali linux and when trying to run command yersinia -G it shows me that i dont have GTK installed. I dont see any tutorials on how to install GTK. Do somebody know how to instal GTK?
