Pratique du Shadowing: I was wrong about VPNs - Apprendre l'anglais à l'oral avec la vidéo
Création de la leçon...
1
The Internet says VPNs are completely useless.
2
They might be right.
3
Or are they?
4
In this video, we're busting some myths.
5
Can a VPN protect you from hackers?
6
Does it make you invisible?
7
Oh. The goal here is to help you answer this question for yourself.
8
Do you actually need a VPN?
9
Get your coffee ready.
10
We're turning on our virtual private network.
11
That's what VPN stands for, by the way.
12
When you are enabling a VPN, you are connecting to a virtual private network.
13
What does that mean?
14
We'll cover that.
15
But for most people, VPN simply means privacy.
16
Protecting you on public Wi Fi from hackers.
17
It's a magic pill, a warm blanket for security.
18
And how do most people know that?
19
Well, VPN companies are great at marketing.
20
They sponsor YouTubers like crazy.
21
And it just so happens that, this video is sponsored by NordVPN.
22
Hold up. Don't click away.
23
I get it. What a conflict of interest.
24
Right? But hear me out.
25
I'm not gonna hold back.
26
In fact, because I'm sponsored by a VPN, I have to be extra harsh to have any shred of dignity left.
27
You know what?
28
You can grade me at the end of the video.
29
Scale of one to 10.
30
One, I'm a trash goblin that sold out.
31
10, I don't know.
32
I'm a good boy.
33
You have to like, subscribe, comment.
34
Deal? Alright.
35
We're all gonna be okay.
36
Are you ready for myth number one?
37
Let's go. HTTPS already encrypts traffic, so VPNs basically do nothing.
38
Right? This is the biggest argument against VPNs.
39
It's a good one.
40
Let's break it down.
41
First, what type of VPN?
42
Because there are commonly two types, and not everyone knows this.
43
In this video, we're talking about personal VPNs, like NordVPN, but not the VPN that your company might provide you to securely connect to their stuff.
44
So we're not talking about this one even though they do kind of work in a similar way.
45
For a personal VPN, the promise is that when you turn it on, it will encrypt or hide all of your Internet traffic.
46
So let's say, for example, when I visit academy.networkchuck.com.
47
Without a VPN, the idea is that if someone can get in the middle of this traffic, sniff it, they can see everything I'm doing, which by the way is not a hard thing to do.
48
I made a video about that here.
49
So if I pay for a course, you might be able to sniff up my credit card information, my email, my password, whatever I'm doing.
50
But if we turn on a VPN, they suddenly can't smell anything.
51
Took that analogy too far.
52
No. It still works.
53
Never chucked a coffee.
54
By the way, what are you drinking today?
55
Doesn't have to be coffee, but it helps.
56
Let's do a simultaneous sip.
57
Instead of going directly to the website, we'll form what's called a VPN tunnel with a VPN server.
58
And in our case, it'll be one of NordVPN servers.
59
This is a secure encrypted tunnel, meaning that all the traffic that the hacker might normally see, it's locked up.
60
It's unreadable, unsmellable, unsniffable.
61
In fact, his nose has stopped up.
62
Yeah. We went too far.
63
I felt it. I felt it.
64
This is the toughest analogy I've ever made.
65
It's fun, though.
66
And when I'm visiting academy.networkchuck.com, the Internet is seeing NordVPN's network and not my network.
67
A VPN simply just changes the network you appear to be on.
68
This is cool, but here's the thing.
69
This worked great for HTTP.
70
It was necessary with HTTP, but now most websites, including academy.networkchuck.com, they use HTTPS.
71
The s stands for secure, encrypted using TLS or transport layer security.
72
This means that without a VPN let's get NordVPN out of here.
73
This means that without a VPN, when I connect to a website using HTTPS, it's encrypted.
74
The hacker still has a stuff nose.
75
So does that mean the VPN is essentially doing nothing?
76
Not exactly.
77
You see, HTTPS, it's not hiding everything.
78
It's encrypting your traffic.
79
A 100%. Well, I don't wanna say that.
80
For example, it's not hiding the sites that you visit or how often.
81
Let me unstuff his nose here.
82
The hacker and your ISP can sniff the fact that you visited academy.networkchuck.com 10 times in the last hour along with any other website you visit, creating a fun little profile on you for advertisers.
83
Isn't that fun?
84
Don't you love being tracked?
85
Don't believe me?
86
Watch this.
87
I've got a little hacking lab sitting here.
88
Kali Linux is sniffing all the traffic from this machine here, my Ubuntu machine.
89
Let's go visit a few websites.
90
I'm gonna launch, Wireshark and Kali Linux.
91
This is what hackers use to sniff stuff.
92
Let's take a look at Ethernet one.
93
We'll start sniffing.
94
Over here, we'll go to academy.networkchuck.com.
95
Stop capture.
96
Filter off DNS.
97
Let's find the packet.
98
Let's search for networkchuck.
99
There it is.
100
Do you see it?
101
Academy.networkchuck right there.
102
Totally sniffable.
103
But I could see you typing in the comments already.
104
You're like, Chuck, what about secure DNS?
105
DNS over HTTPS.
106
Yeah. That will encrypt this information.
107
And in theory, it should hide this information from hackers sniffing your stuff and your ISP.
108
In theory, let's try it out.
109
I saw David Bombal do this in his video, this one here.
110
Check it out.
111
It's pretty good, but watch this.
112
We'll go over here, we'll enable secure DNS.
113
Boop. And we'll use Google.
114
Let's start capturing again, and we'll go to, like, I don't know, cisco.com, microsoft.com.
115
Let's go see what we found.
116
Now it looks like we didn't find any DNS packets, but let's try this.
117
Look at that.
118
This is so crazy.
119
That looks like DNS to me.
120
That doesn't it?
121
Easy for me to say the SNI gave us away, and you're like, what is that?
122
Not gonna dive deep into that right now.
123
Go watch David's video.
124
The point is even with secure modern standards, we're not getting the anonymity and privacy we want, and this is where a VPN shines.
125
Because when you connect back to NordVPN, all that traffic from HTTPS, all your web traffic, your DNS queries, and also everything else your computer's doing.
126
It's not just your web browser talking to the Internet.
127
You get all your apps and your games constantly talking to other servers on the Internet.
128
You don't even know what they're doing if they're secure.
129
Alright. Fresh capture.
130
VPN on. We'll go to academy.merch.networkchuck.com.
131
Easy for me to say.
132
Cisco.com. Go to networkchuck.coffee, and let's see what we find.
133
Nothing with Cisco.
134
Nothing with network chuck.
135
Everything and notice the protocol here.
136
Everything is WireGuard, which is what NordVPN uses to secure you.
137
Connecting to a VPN encrypts all of that.
138
And now we've given our hacker and our ISP a stuffy nose again.
139
I think we can say that myth is busted.
140
Boom. Hold up.
141
Can't NordVPN see all of our stuff?
142
Yes. And that's myth number two.
143
A VPN just shifts your trust from the ISP to the VPN company, and most of the companies don't deserve it.
144
Let's pop the hood on that.
145
And honestly, this might be the strongest argument against using a VPN because we may be able to hide all of our traffic from hackers in our ISP, but that involves putting all of our trust in the VPN provider.
146
PureVPN said no logs, meaning they don't keep track of what we do when we visit websites.
147
They don't have a record of it.
148
Yet their logs that don't exist helped unmask a net stalker.
149
Now while I agree that's a good thing that happened, still, come on guys.
150
You said no logs, but hear me out on this.
151
Dishonest providers doesn't necessarily mean the tool is useless, but you do have to verify who you're trusting.
152
And when it comes to the Internet, you're gonna be trusting someone.
153
So I do actually use NordVPN a lot, and they claim no logs like a bunch of other companies do.
154
So why do I trust them?
155
Well, they just passed the sixth audit on their no logs assessment, and this is an independent audit, not them checking themselves.
156
And by the way, as I'm naming this stuff off, it doesn't have to be NordVPN.
157
It can be you using this criteria for your VPN.
158
Check it. Also, NordVPN uses RAM based servers, which means no disc or database to seize or give over to law enforcement.
159
And then jurisdiction's a big one.
160
NordVPN is in Panama or they're under the jurisdiction of Panama.
161
This is important for us because there's no mandatory data retention law in Panama, and they don't need to store logs.
162
Can I prove any of that?
163
No. At the end of the day, it comes down to trust.
164
NordVPN has given me enough reasons to trust them with my VPN access, and you'll have to answer that for yourself with whatever provider you choose.
165
Myth number three, a VPN makes you invisible.
166
I'll go ahead and bust this one.
167
No. It doesn't make you invisible.
168
And this one you kinda already know.
169
Right? Like, a VPN can make you feel more secure.
170
It can make you a little bit more private, but it can never ever make you fully invisible.
171
Remember, it just changes the network you appear to be on, but we're not Harry Potter here.
172
No invisibility cloak.
173
Well, let's see them.
174
Put it on. Woah.
175
You know, I'm gonna have at least one Harry Potter reference in this video.
176
You know this.
177
Think about incognito mode.
178
When you turn that on in your browser, you kinda feel like a hacker.
179
Right? Like, no one can see me.
180
All that's doing is not saving your browser history on your computer.
181
It doesn't mean that the stuff you visit isn't looked at upstream.
182
And a VPN is kind of the same energy.
183
Like, it'll hide your IP address, but your IP is like 5% of how you actually get tracked.
184
If you're still logged into Google, cookies are still following you around.
185
And the big one, browser fingerprinting, your screen size, your fonts, your extensions.
186
There's a big thing about LinkedIn looking at all your extensions recently.
187
It adds up to a fingerprint that's essentially you, and you don't need an IP address to know that.
188
Actually, I'm curious.
189
There's this website.
190
We can test this out right now.
191
Cover your tracks.
192
I'm gonna test my browser.
193
Oh, this is fun.
194
I am not protected, it says.
195
Myth three, busted.
196
Easy. Myth number four, a VPN keeps you safe from hackers.
197
Yeah. This gets into weird territory because that's kind of the advertisement.
198
Right? This is the promise.
199
Turn on a VPN and the cartoon hacker can't touch you.
200
A VPN alone will not protect you from the stuff that actually gets people.
201
It's the phishing emails.
202
It's the fake shopping sites.
203
That extra RAM you tried to download.
204
A VPN essentially does nothing about any of that.
205
Remember, a VPN just changes what network you appear to be on.
206
It builds an encrypted tunnel, but the tunnel's job ends the second your traffic leaves it or the second you click the wrong link.
207
The danger was never inside the tunnel.
208
The danger is you.
209
So, yeah, the myth is busted.
210
Now a VPN alone will not protect you from hackers, but NordVPN really isn't just a VPN anymore.
211
What they actually are now is kind of an all in one digital security app, and they have next gen antivirus features that help block phishing, malware, trackers, and the stuff that actually gets people hacked.
212
Like, let's be honest.
213
This guy is used sometimes downloading some images, malware deleted.
214
They even have email protection.
215
I didn't know that.
216
And a crypto wallet address checker.
217
How does that work?
218
Flag suspicious crypto wallet addresses to keep your transaction secure.
219
That's pretty cool.
220
Search safety results.
221
Oh, dude. They have a URL cleaner built in.
222
That's pretty sick.
223
Hijacked Session Alert.
224
Notifies you if your session cookies are found to be for sale on the Dark Web.
225
What? This is the stuff that gets, like, YouTubers hacked.
226
Pretty sure this happened to Linus, and it will alert you.
227
And, essentially, hackers can avoid having to steal your password by just getting your cookies.
228
This is the whole thing.
229
Look at this diagram.
230
Looks fun. Now, seriously, as far as VPNs go, a NordVPN isn't awesome.
231
But the fact that it's more than a VPN is kinda cool because you can still have normal people, not techies like us, turn it on, and they think, oh, yeah.
232
VPN is protecting me.
233
In this case, it is.
234
They just don't know it.
235
So trick your family and friends into using a VPN that actually protects them.
236
That felt very salesy, but that was a good line, wasn't it?
237
Anyways, check out my link in the description below.
238
NordVPN did sponsor this video and allowed me to deep dive on VPN stuff.
239
They are a massive supporter of my channel, so show them some love.
240
I actually use them a lot.
241
Now on to myth number five.
242
A VPN is just a privacy thing.
243
It's all about anonymity and keeping you invisible, which we just talked about, but it's not.
244
It's actually an anti harassment tool.
245
One thing people know about VPNs, and it's shouted from the the rooftops by, like, every YouTuber ever, is the fact that it hides your IP address.
246
Now is that a big deal?
247
A lot of people will say it's not, but I say it's stinking is.
248
Because in a lot of cases, your IP address points to where you physically are.
249
Go ahead. Try it out.
250
Go to, like, where what'smyip.com.
251
I'm not gonna show you mine because it'll show you where I'm at, but it'll have a pretty good idea of where you're located.
252
So whether you're trying to avoid a DDoS attack from a 12 year old with $5 or you're trying to avoid being swatted, being able to change what network you appear to be on also changes what location you appear to be in.
253
It goes from a privacy thing to also a protection thing.
254
Not to mention while I was in Japan for three months, I used NordVPN all the time to watch my shows back home.
255
The geo unblocking alone is fun.
256
And I know I know a bunch of these VPNs use shared IP addresses that get blocked.
257
That happens to me, which is why a dedicated IP, which is offered by NordVPN and other providers, is super helpful.
258
Yeah. You can actually get a dedicated IP address assigned to you.
259
You can avoid pop ups that ask you to prove to be be human, avoid those IP blocks.
260
Now quick note on dedicated IPs.
261
Your traffic is still encrypted, your IP and virtual location are hidden.
262
But because a dedicated IP is tied to your Nord account, which is also tied to your email, some activity can be traced back to that Nord account.
263
Just be aware of that.
264
Myth number six, normal people don't need a VPN.
265
And, you know, honestly, a lot of people who don't necessarily care about their privacy online, they're not surfing anything weird.
266
They're just visiting Facebook.
267
They don't care if their ISP knows that.
268
For most people, they don't need a VPN on all the time, but that's the key.
269
A lot of those tech nerds, we like to have security all the time.
270
We don't like to be tracked or fingerprinted, so we turn on VPN.
271
We do all the tricks.
272
But for most people, they don't care about that.
273
But I still think normal people need a VPN sometimes.
274
It's event driven, and these events are kinda multiplying.
275
Like in the summer of twenty twenty five, The UK rolls out an age verification law, and overnight, VPN demand explodes.
276
So a law flips overnight, or maybe you're traveling and you're on sketchy hotel Wi Fi, or a site you normally visit is geo blocked.
277
That's when you reach for a VPN.
278
So the answer to do you need a VPN isn't just a flat yes or no.
279
I think it's, you know, sometimes you do.
280
Probably not right now when you're watching me on YouTube.
281
That's HTTPS.
282
You may not care if your ISP or or the hacker sniffing your stuff right now knows that you visited YouTube, but you might need it in some of the situations we mentioned.
283
So here's the verdict.
284
End of the video, we're gonna land this plane.
285
What's a VPN actually good for?
286
And if you jump to the end of the video right here from the beginning, shame on you.
287
Get back there.
288
I'm just kidding.
289
A little bit.
290
So VPN is good for hiding your metadata from an ISP or a hacker, stuffs their nose right up.
291
It shifts your trust from your ISP to something you can trust and verify in most cases.
292
And with NordVPN, you get more than a VPN.
293
You get dedicated IP options, and plus it's an all in one digital security app with next gen antivirus features.
294
But what a VPN is not is it's not gonna make you invisible, and it's not gonna magically make you hacker proof.
295
You still have to be, you know, smart online.
296
You can't just run around without a care.
297
You have to have some good cybersecurity hygiene.
298
So I wanna hear from you.
299
What do you think about VPNs?
300
Are you gonna use one?
301
Do you use one?
302
Comment below.
303
Also, how did I do?
304
Scale one to 10.
305
Be nice. And be extra nice and show NordVPN some love for sponsoring this channel and making a lot of what I do possible.
306
They are awesome.
307
That's all I got.
308
I'll catch you guys next time.
309
Hey. You're still here.
310
If you're new here, I like to pray for you, my audience, at the end of my videos.
311
I believe in the power of prayer, and I genuinely love you guys.
312
I wanna see you succeed.
313
I wanna see you have a fulfilling life, and I believe the best way I can do that is to pray for you.
314
I know it's weird, but let's do it right now.
315
One, three, pray.
316
God, I thank you for this person on the other side of the screen.
317
I thank you for who they are.
318
I thank you that they're curious and that they're passionate about tech.
319
And I ask in your name that you just bless them indeed right now.
320
If they're going through a hard time, whatever it is, give them peace right now.
321
Give them courage and encouragement that whatever it is will pass, and I ask that you give them strength to make it through make them yeah.
322
To I can't talk right now.
323
Give them strength to make it through it, god.
324
Bless their careers and their jobs and their families.
325
Let them flourish.
326
Help them to I ultimately just know you, god.
327
In some way, they would know you because I believe that is where we find ultimate joy.
328
Help them to take this knowledge that they're learning here to encourage them and and maybe it light a fire in them to jump into cybersecurity or just reignite their fire for what they already do.
329
God, I just thank you so much for this person.
330
It's in your name I pray, Jesus.
331
Amen. Thanks for letting me do that.
332
I'll catch you guys next time.

Qu'est-ce que la technique du Shadowing ?
Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
