Cybersecurity for Beginners: How to use Wireshark

[@steventelfer8186]

Wireshark is one of the most important tool in IT. Mastering this tool is such a great advantage. Thank you!

[@Adam-ey2jc]

I have always wanted to learn more about Wireshark but felt imitimidated by it but this video does a good job of breaking down some of the confusion around it. Modern computers are so complicated! I would love to see more videos about Wireshark or of this nature.

[@KyanoAng3l0_Mtvtks]

Been using this alongside Portmaster. Makes me giddy to know that my tweaks and mods to minimize telemetry on Windows 10/11 work! :D I'd only see Windows telemetry being blocked by Portmaster when Windows tries to check for updates in the BG.

[@cryptoafc7655]

Portmaster made my windows go in blue screen mode

[@KyanoAng3l0_Mtvtks]

@@cryptoafc7655 Better bring it up to the Portmaster devs or in their community (can't mention the name here cos YT auto-deletes comments that mention other socials, lol). I haven't encountered that yet, but Portmaster does use a kernel driver so BSODs are possible.

May i know what kind of tweaks mods you do to reduce telemetry. I am interested to know

Yes, great video. I'm in cybersecurity program in college and so far I'm doing the general studies but I can't wait to get into the cybersecurity stuff like this.

[@_Garm_]

really intersting tutorial, would love to see more wireshak tutorials! :D

[@shackcf]

Been using Wireshark on personal PC for years. While working it was Network Instruments that was pre-2009. Thanks for the videos.

[@Embbrr]

Would love more videos like this, I was struggling with learning a lot of protocols for my IT program I am in, and this video was explained perfectly, The examples on screen were very easy to follow, and your approach to explaining how exactly things worked was very easy to follow, need a full series like this, from Zero to Hero! Great job honestly.

[@CoderSal-XIII]

Wireshark is such an important tool. I use it all of the time both at work and at home. Such a great tool. Good video for beginners.

[@buraduri]

This video seems like it's missing an important part of the usefulness of wireshark. How do I identify what I don't know what I'm looking for? No shit if I connect to youtube I'll see youtube but what about unrecognized connections from potentially malicious software on my PC

[@joepjoep9531]

You have to look at this differently it’s made for people who never used it before you can’t start somewhere in the middle or very complicated if you are learning something new

[@pcsecuritychannel]

Wireshark is an investigative tool, not anti-malware. If you want a quick and easy way to detect malware, this isn't it.

[@seansingh4421]

In that scenario you would wanna look for network connections involving unusual ports, so lets say you have a typical Windows home edition PC, but you spot a some random executables (Apps and .exe) successfully connecting via Port 22, Port 3389 BUT you don’t even have Remote Desktop feature because that’s unavailable in Home editions. This is just one example and trust me this can be a rabbit hole of being over suspicions but this is one example of an outbound C&C connection

[@johnsmith1953x]

[@joepjoep9531]

Good video for absolute beginners

[@FakeJeep]

Very simple and straight forward tutorial.

[@random-user-in-yt]

Good tutorial but I think you miss a important point for some people who can not see any readable DNS query. If DNS query is encrypted(maybe by HTTPS), WireShark can not capture those DNS query in readable string.

[@ttrqs]

been waiting for a vid like this, ty

[@davidbell7094]

Excellent info picked up,through this video. Yea I'd love too see some more videos like this,is good too understand more of what it all means,cheers buddy!

[@wannabedal-adx458]

1) More content on Wireshark would be great (aka Tutorials). 2) How much does Wireshark cost?

[@Taffy84]

It's free

[@squirlmy]

Open Source and free forever, unlike for example Metasploit, which is partly open and partly with proprietary upgrades.

[@faithtechnology3542]

hey just wanna tell you that you are a great guy these videos are so easy to understand

[@damianpodgorski6977]

Yes please, Leo, more videos like this one. Thanks as always.

[@jaycolife2314]

I’m interested in computer science and how they connect with the world. It’s fascinating but intimidating and overwhelming.. I subscribed hoping you’ll put up more content like this. Break it down for us..

[@wissy006]

I liked the video, it was very interesting thanks Leo😄❣️

[@HazexDimond]

great stuff 👍 many useful cases for this tool last time i used it was to check my dns traffic to make sure it was all configured/encrypted correctly for a deeper dive, chris greer has some good wireshark content on youtube, explains filters well

[@x9v8k]

Yes, please do more videos to add on this one (advance). Is there anything further to see if the connections are not easily identifiable? Is there a way to pinpoint a remote connection quickly?

[@vaclovas-art]

DNS can be also encrypted using DNS over TLS or DNS over HTTPS. So than you cannot see any DNS requests which was made. ISP also cannot see it 😊

[@xbeast7585]

Thank You So Much For The Video Sir Please Make More Videos On How To Use Wireshark 💓✨

[@TheRealWillM]

I don't know if you do this already but maybe create a 'related series' as an aside to the main thrust of the channel. Anyway those are my thoughts and content like this is very useful for 'dipping' the toe in, which may be useful down the track.

[@UserforPhone]

I am very curious about why there is no option to have a professional packet capturing software like Wireshark for mobile/Android?

[@bretjohnd.morales9310]

[@priyojitdeb1891]

[@miltonthecat2240]

I would like to snoop on WiFi traffic to the various WiFi-enabled devices that are proliferating in my house. This is mostly a curiosity, but I expect there will also be surprises, some perhaps concerning. I've been told that I can use Wireshark to do this, but I need to add a separate dedicated WiFi interface on my PC that supports "promiscuous mode". I found some trailing edge WiFi dongles that are supposed to support promiscuous mode, but I also need a compatible driver. This is where I have hit a dead-end, as I have been warned that the drivers for these trailing edge WiFi interfaces often have embedded malware, and I don't have a sacrificial PC available to dedicate to this effort. Any light you can shed on this in a future video would be of interest to me.

Please create a video on accessing malicious and phishing domains while using NextDNS. A general review of NextDNS would also be be nice!

[@gyl9735]

[@yt4me2lurn]

Hi, once you see the packets that show the sites you may not want, can you block those or will they just keep communicating each time you go to that site ?

[@VentelHD]

I collected all ad urls and added them to my hosts file. Can now browse anyplace without background ad data exchanges without consent.

[@kaeez]

What browser are you using?

[@giausjulius4]

Maybe we would go more in depth on this software sometime? What do the colors mean, if anything? How do you really determine what is and isn't a good IP once you see something you don't recognize? How do VPNs interact with and change the packets you see? Stuff like that. I'm just getting into the whole cybersecurity scene. Although I've been careful since the days of Limewire to never click links, ads, and to distrust anything I see in emails, etc, I haven't ever really been big in actually finding out what goes wrong in the system and network. I visit the same sites that I've always gone to. But I find myself wondering if somehow they are getting in anyway even if I've been careful just by little things I notice happening on my PC once in a while such as the CMD window opening for just a moment and disappearing, a game minimizing to desktop with no input, etc. These coupled with data leaks from big tech leaking email, account info, and so on. It's probably totally benign and I'm being paranoid but you never know.

What about reading the cap file...how can that be done?

[@shinigamirenegade]

Not going to lie if you start using Wireshark and if you have familiarity with osi model like layer with layer 3 routers packets and layer 2 switches frames then it's not bad at all. To read the traffic and knowing udp tcp protocols you're golden. I think I need help with adjusting ethernet adapter into promiscuous mode and the other mode. And what's the functionality.

If that doesn't block the connection it's pretty pointless. Netguard on Android can do that and can block every single individual app or site that the app connects. I don't know if there's something like that for Windows.

[@HabeebSule]

This is an awesome video thanks.

how would one check a hacked PC on this environment?

[@GYTCommnts]

My old Outpost Firewall used to show me similar information, separated by the apps (or component of the O.S.) which was generating the connection... Is there a tool for this or is there an option available on Wireshark for monitoring this? Or is only doable on firewalls?

[@sauplink7975]

To achieve what you were doing with Outpost Firewall-monitoring traffic per application or OS component-you can use Wireshark but with some limitations, as it primarily focuses on packet-level analysis rather than app-based monitoring. However, with the right filters, you can approximate similar functionality by analyzing traffic specific to certain processes or connections. Wireshark allows you to apply **display filters** to identify specific network traffic based on protocols, IP addresses, or ports, which indirectly helps monitor app activity. However, it does not directly show traffic sorted by applications unless you pair it with OS tools to map the process to network traffic. For more straightforward app-based monitoring, a dedicated firewall or monitoring tool like **PRTG Network Monitor** or **SolarWinds Deep Packet Inspection** might be more suitable【7†source】【9†source】. If you want a direct replacement for the Outpost Firewall's style of monitoring, consider using **NetFlow** or **Deep Packet Inspection (DPI)** tools, which can classify traffic by app category and offer more detailed insights into app-level connections【9†source】. If you still prefer Wireshark, combining it with system monitoring tools could provide a similar overview, but it will require manual filtering and linking to specific processes.

[@KirenKK-te7pb]

Wireshark has to be a " backdoor" to catch " backdoor entries " too. The ethics of the admin of any empowerment matters as much as the expected service😅!

[@TheTitaniumSkull]

This reminds me of back in late 90s early2000s there was a free app (can’t remember name) that backtracked incoming pings.

[@CSGhostAnimation]

Now if we could just firewall all traffic until I actually open google, or open my video game, then I would be happy

[@alberts6096]

there should be a function in wireshark make a image of all connection, install software, make image again and compare.

[@ZephniStrife]

I don't know why but my instant reaction to something like this is: How can I trust it? As it could quite easily see current webpages you are on or applications you're typing passwords into, and then hide its ip: protocol transaction with a server... but it's probably fine 👀

the biggest question is are wireshark is safe to used it since all virus check website say have something on it?

[@Holycurative9610]

If you try to download a cracked version of any program it will come up as having a virus because of the software used to crack the program This is piracy and if you want the full version of a paid program then go pay them for it and you don't have false positives for virus alerts. Wireshark is free and used by a lot of people so it is very unlikely to come preloaded with a virus. I've just installed Wireshark and there are NO viruses at all...
