Hacker Demonstrates Security Risks Of Free Public Wi-Fi

We constantly hear that using free public Wi-Fi is a serious risk when it comes to our personal information. We had a hacking expert show us the very real risks. WBZ-TV's Christina Hager reports.

You can use that method to kick people out of a public wifi so u can use it alone.

i just did something similar to this at my cyber defense club. you can even create new DNS names so they’re not as obvious as fake. and the software can copy how actual websites look just by passing the URL during setup

I learned to look at network on pc, cellphone, etc. You will notice names you never saw before. On pc you will see if someone is on iPhone, Android, and see if someone is on your network all the time. You will learn over time who is not supposed to be there.

the lock just means that the packet are encrypted using https protocol. Doesn't mean that u re safe

FYI to the people in the comments, VPN won't necessarily protect you from these attacks. Even though the websites you visit will be secure and not visible to the hacker, they can still gain your IP address since you connected to their "wifi" in the first place.

FYI lock just means a secured connection to the server. Not that you can't be hacked

gotta put 0's and 1's on the screen to show this hacker is serious

[vrevivez]

So, setting up a phishing link makes me a hacker ?

[wahidkurdo]

Just because the site is secured with ssl that dont mean its safe

Of course he's got his little MacBook with Linux on it, now that's a stereotypical hacker computer, like my laptop.

Nowadays these mitm attacks aren’t as relevant due to hsts which basically tells your browser to force https and not http which makes downgrade attacks and cookie hijacking significantly harder https also encrypts your traffic so it cannot be read by an attacker where as http does not

[victoriawicker]

This very scary but also it's all about paying attention to the very few important details

I run a public wifi. you gotta isolate each local device from each other via mac/ip address and contain them inside a vlan inside a guest network.

what they're showing here is stupid.

interviewer: could you take someone's credit card information?



hacker: I already have

I one time shutdown a whole hotel wifi network out of curiosity. It was dumb but it was worth it. It through the whole hotel into a crazy panic loop. Is it recommended? No! Should anyone try it? No!
So why did I do it? To show the way of how someone can walk into a hotel, connect to the guest wifi, and shutdown a network. I hope they fix this before the real bad guys take everyone's information

[tigerlily]

these people are way too smart and too good

Fact: "The Lock" doesn't mean the website is secure, hackers can obtain that lock as well!

[ferozreviews]

Calling an ip address a series of numbers is actually a hack.

[jackwan]

I don't think people will waste time on public wifi if login is required

[Nahoogg]

That can be done with a mim attack on virtually any wifi you can crack or connect to.
