Cyber Weapons Lab, Episode 202
This is the last part of our four-part series looking at how to protect a fresh Ubuntu install. In this Cyber Weapons Lab episode, we look at open-source firewalls and how they can protect your system while still maintaining privacy. We also show how to use antivirus programs like ClamAV without sending any data to remote servers.

installing antivirus on ubuntu
2020 is really cursed
Great content Nick!
Awesome! Would love to see you guys STIG a box next
Hmmm. Love how this gets uploaded the day after I start trying to secure my ubuntu system
Sus
Illuminati theme plays
It have happened to me with some other videos as well, 2 times.
same
This is helpful. I have been waiting for this a long time…. For Kali. Thanx💋❤
this guy seems really confused, why is he showing the same stuff over again?
at least he knew "sudo !!"
@@james_gemma but not apt
ctfu lol .. damn kids with their intentionally loud keyboards and Deh-Bian based linuxes!!
Thanks dude, I need this!
new upload lets go
Oof, two minutes ago this man posted a vid I was about to look up.
Usually the stuff on this channel is pretty good. This video though is very sub-par. The majority of it basically boils down to "I already did this on my system and I don't want to undo it so just read the article." (not to mention editing mistakes)
Come on, you guys can do better than this...
I mean, usually they don’t explain too much and just expect everything they do to go the same way on your computer. I don’t think this video is much better or worse
Linus? Awesome top thx! A whole video on vetting libre software via multiple Static Application Security Testing (SAST) Tools would be great.. great job
Overuse of sudo. Why sudo on the wget when you're in a sub of your home directory? You're just messing with file permissions for no reason doing that. Also, you should be extracting lynis to /opt as it is user software. Also also, why didn't your sudo ask for a password? If you're "securing" Ubuntu, one of the first steps would be requiring a password with every sudo. This helps prevent accidents and overuse.
Bruh, want to be friends?
son.. you need to slow down your rate of speech or speak clearer.. I want to hear what you have to say but it all gets jumbled in my ears and comes out in a way I can not understand.. Ah! an article.. excellent! Woof I am 68 and this goes way to fast for this old fella.. so I am gonna save this in my fav's and come back to it when I get my Linux system up and running.. I am building a bunch of linux systems here at home for my personal systems and dump these windows pain the butts.. Thanks for doing this YT channel.. I just discovered it and like a lot of your videos.. so carry on.. see you on the tube.
I am interested if you make a Privilege Escalation video🙏
That's messed up. Even Ubuntu has to be on lock down.
Just about ANYthing "connected to the internet" can be hacked given enough time to find an exploit...
@That_dog what, "open source"?
\0 is such a great channel for all kinds of "handy" computer skills...
My Ubuntu partition mistakenly deleted and extended it to Local C drive. How can i get my files in Ubuntu back. i used lot of recover softwares but i didn't get it . please help me...
No mention of tripwire? Also you can speed up clamscan by using the "-i" (print only infected files) or "-o" (suppress all "file is okay" messages). Printing status messages to the terminal tends to be a bottleneck, I think.
Oh, wait, this is regarding using Ubuntu as your primary os hence not mentioning tripwire.
One question , can i pute a script using nfc? Into a card??
Regarding the snitch firewall. If I already have ufw installed, should I uninstall/remove it or just disable?
Wondering if ufw might conflict somehow with snitch, even if it’s disabled.
Thanks🙏
I would just use ufw. Its a frontend for IPTables, so its fine.
if u use ufw why change it? ...
Switching over next year
Bro I am so bad at this can someone explain to me. Why no matter what I do the Command Prompt works nothing like the ones they do. I can't even do the cloning thing for downloading something from git hub. I stressed and I want this to work help please. Anything I do it just says " is not recognized as an internal or external command,
operable program or batch file." or "The system cannot find the path specified." and I know I am typing it right.
I'm installing Metasploit on Xubuntu 18.04. It requires installing Java and a few other prerequisites. A video on installing Metasploit on Ubuntu might be useful to your viewers.
Can you do a video on securing a Linux server? Im assuming some of this information is the same.
It's the same thing, it just doesn't have a gui, on my servers I change the default ssh port to something else, like 5577, install fail2ban that will block ips after an x failed amount of login attempts (needs configuration) generate ssh keys, disable root login, and install my keys, for maximum security remove password login completely, or setup a 2fa Pam module, you can find plenty of videos in UA-cam.
Hi, I'm still waiting for the video about inside hacker's bag.
Hi ... I've been having issues with hackers remote accessing my POPS OS UBUNTU version 20.10 ... Need some hands on help ... I could pay you and come to wherever you are in the USA for some lessons to further understand my system and prevent hackers from accessing my laptop. Can you help???
I dont understand if you cleaning or secure or both in your pc.//thank you //
🗿I know that is stupide question !
Pls i want this!!! Video Idea:Use esp8266 to do a beacon swarm and use the beacons to redirect to access point(like the guest login page) and play a rickroll or something other useful.
Ubuntu is no more the only such linux distro. See Pop os and Manjaro Linux if you need arch based distro for an early beginner. They are all easy.
Clamtk graphical user interface would be easier for new users than using command line I would have thought, do you not like Clamtk for some reason? Also cclam scores very poorly in independent AV tests anyway, something around 60-70% detection rate for linux, the premium AV’s scored better
when administrating linux clients no one uses graphical interface...
@@lnk6098 that’s true in a professional setting, just suggesting that the graphical interface is worth mentioning for new users of linux in a private/home setting, not that they’ll need it anyway tbh
want a full course for hacking from you
isnt the part at 6.00 the second time
it is. editing mistake.
Can you do one for kali Linux?
its the same on kali since its the same "system" ...
@@lnk6098 oh. I figured there would be small changes that might need to be made between the two distros
@@matthewmcwane9569 No Not really
@@lnk6098 ok well thanks
Why not install Lynis from the official repo so that it will get updated as new versions come out?
because distro repos are often behind. For example. the ubuntu apt repo for lynis is version 2.6.2 which was release February 13, 2018!!! this one he got from the official github repository is 3.0.1 which is the latest release.

Clamscan.. say that ten times fast...
is parrot Ubuntu ?
Yeah, it's based on it
@@amparorod2000 it's based on it as well. Easy way to check is to look at the wikipedia page for the Linux distro that you're wondering about and it'll give you some info. You can also find info like that on the distribution's own web page but that info may not be the easiest to find as it might not be on the main page.
Parrot is based on Debian as is Ubuntu
⚠️ I need help. ⚠️
I have an idea in my mind for "stealing" WPA&WPA2 WiFi passwords, and i can't find that someone did this on the internet.
Steps:
1. Capture the handshake from victim.
2. Make a fake/our AP with the same SSID as victims WiFi SSID. Our/fake AP needs to have a password protection (it needs to look exactly the same like victims WiFi when he checks the settings on his phone/PC)
3. Now we disconnect user/victim from his real WiFi and prevent/block him from seeing his real WLAN Name when he check the settings on his device.
4. Victim will now ONLY see our fake AP and he will think it is his real WiFi so he will try to connect and enter the password in the password field. (Or maybe the phone will connect to it automatically because it will think that this WiFi is trusted one)
5. We will now capture the password which he is trying to enter and we will compare it with the handshake we captured earlier.
6.1. If password and the handshake match, we will continue to step 7.
>6.2. If password and the handshake doesn't match, we will go to step 6.3.
>6.3. We will not accept the user/victim to connect to our fake AP and we will request the password again (like on any other normal WiFi)
7. Now that we captured the correct password we will accept the user/victim to connect to our fake AP (just for a few seconds) (so the user/victim thinks there is nothing wrong and that he successfully connected)
8. We will now turn off / stop transmitting our fake AP and in the same time we will stop blocking user/victim from seeing and connecting to his real WiFi (he probably won't notice this step because his device will probably automatically connect back to his real WiFi within few seconds)
FINISHED:
1. User/victim didn't suspect anything because he didn't go through sketchy fake login web-page. (A lot of other hackers use "Evil Twin Attack" with fake web page of your router, asking you to enter a password to update the router, or they use some similar tools, like Fluxion (same router update fake web page), Wifiphisher (fake router web page...). They are all basically the same attacks.)
2. We got the correct password for that WiFi.
THE END
If you read all of this Thank You So Much!

Thank you for help!
I am very new to this field, but I could understand your point and your English just fine.

Virus hides in registries of windows bases system, Ive never known Ubuntu to get a virus as it is Linux based, however it can get malware.
where TF is Kody K.
Interesting. I thought enabling the firewall was enough.
Firewall and that, still won't be enough
If you are sprawling all over the internet and downloading and/or running foreign files constantly, or you are trying many different pieces of software I would definitely still be worried as it's only a matter of time in that situation. If you are using the machine for general and minimal use for research, games, websites that lean towards being "safe" and you aren't downloading strange programs I wouldn't worry at all. There are many areas in between but just be sure to install and use only what you truly feel you need. The more you bloat a machine up the more risk it presents.

I found many Windows viruses on my Linux Mint machine.. still good to clean it up to help prevent infecting a friend's Windows machine.
Just run OpenBSD and you‘re done.
What is the point of the video if you don't want to do anything it's just a waste of time
"it is all about money", ads and marketing my friend...
Wait you are asking what's the point because you yourself don't want to do anything? How is it a waste of time, especially for newcomers?
This is not a mere coincidence that i recently installed linux and kali and now this pops up....

Pretty sloppy video... Some parts are done twice (the clam AV scan for instance), that some editing issues easily fixable but not being bothered to wait for lynis to finish before shooting the end of the video and worse, not feeling ashamed to simply read an article about installing opensnitch because "it s too long and I don't want to do it again"... This is plain laziness dude...
linux requires zero AV ....

Wait, what's this???
@John I just sector edited all the windows icons to open source ones from the torrent I downloaded. no one would know it's windows 10... except the damn updates...
yeah I know, we've come a long way from where things started. Ubuntu is the sacred cow for the masses, and still is hit and miss. god, think about this - windows now has it's own subsystem for linux. install your own flavour INSIDE windows.. WITH a gui these days.
We're sailing on dire waters... thanks 2020..
Windows simply is more vulnerable due to popularity. However it is also true that linux is much more safer in comparison to windows. Windows 10 is a bloated piece of crap, all the background processes and services that gets left over even after uninstalling apps should be treated as spyware.
