How a Wi-Fi Hacker Snoops on Your Laptop and Mobile

You have likely heard of the dangers of using unsecure public Wi-Fi, so you know that hackers are out there snooping. It is pretty easy to hack into a laptop or mobile device that is on a public Wi-Fi connection with no protection. Hackers can read your emails, steal passwords, and even hijack your website log ins.

Let’s imagine that you are in a local coffee shop with your laptop. All someone has to do is download a wireless network analyzer, which usually has a free trial, and with the right hardware and additional software they can often see what everyone is viewing online…unless they are protected. In some cases they can also read your emails that are going out and received, as well as texts you might be sending. Scary, right?

Tips on How to Use a Wi-Fi Hotspot Safely

You now know what you are up against when you connect to a public Wi-Fi spot, but you should also know that you can use them with some safety in mind. Here are some tips:

  • When you log onto a website, only use an encrypted connection. This means use the URL that begins with HTTPS, not HTTP. Keep an eye on that as you move from page to page because some sites will send you to an unsecured page, which makes you vulnerable.
  • There are also many websites out there that will allow you to encrypt your browsing session automatically. Facebook, for instance, has this. To turn it on, go to your “Security” settings on the site, and then enable “Secure Browsing.”
  • If you are going to check your email, login to your web browser and then ensure that your connection to your email client is encrypted. (Check by looking at HTTPS). If you are using Outlook, or another email client, make sure that your settings are set for encryption.
  • Don’t use any service that is not encrypted when you are on a public Wi-Fi connection.
  • Consider using a VPN when you are connecting to a public Wi-Fi connection. There is a small fee for this, but it’s well worth it.
  • Beware of “evil twins” which are rogue networks designed to mimic legitimate networks. Example “ATT WiFi” my be “Free ATT WiFi”. Other than downloading special software that detects evil twins, the best case is to ask someone who’s knowledgeable as to which network is the safest.
  • If you are on a private network, make sure you realize that they are also vulnerable. Anyone who knows how can spy on the network. Again, use WPA or WPA2 security so the connection is encrypted. However, if someone guesses or knows the password, they can still spy on any device that is connected

Thanks for the advice. We are very careful about security. In fact it is hard to be too careful.

Good to know Robert. I rarely use hotspots because I know how vulnerable they are to hacking.

Hi Robert- I don't use public wi-fi anymore because of this. But I know I am still vulnerable.

Hi, Robert. 

      Aside from the hackers, I have found that using hotel wi-fi is the best way to pick up malware.  They get through every layer of security that I have on my computer.  I finally quit using "free" hotel wireless.  Today, I use my smartphone as a wireless hotspot.  That seems to have solved the problem.

Thank you for the information. I think we all know the public sites are not safe, but for many, the "free" option is too hard to pass up.

Old Wi-Fi technology using Wired Equivalent Privacy WEP, since 1997, or Wi-Fi Protected Access WPA (aka WPA1), since 2003, uses weak RC4 (Rivest Cipher 4) encryption, is not secure, and should not be used.

WPA2, using strong Advanced Encryption Standard (AES), is more secure, but it is old technology, used since 2006, with some known security weaknesses.

WPA2 is being replaced by stronger security in new WPA3 devices, announced January 2018.  When upgrading Wi-Fi routers, smartphones, tablets, and PCs, look for WPA3 support, often found along with fast Wi-Fi 6 (802.11ax).

WPA3 has backward compatibility to support WPA2 devices during the technology transition until all devices are migrated to WPA3. But the strongest security is achieved when using all WPA3 devices, not mixing WPA3 with WPA2 devices.

WPA3 includes encryption security features for use at public locations, known as Wi-Fi Enhanced Open networks.

5G cellular is also being introduced that will provide a high-speed secure connection without using Wi-Fi.

Meanwhile, use long strong random passwords and SSID names, avoid using public Wi-Fi, and turn off Wi-Fi SSID broadcast on your router.  Also, use two-factor authentication where available.

Robert Siciliano - You always raise my awareness. I was in Austin, TX for about a week. I like to visit my favorite Coffee Shop a couple miles aware from the Convention and Hotel. This time when I got there, I noticed College Students. All were on their smart phones or Lap Tops. A few (just a very few) had a coffee cup on their tables. It made me think about you and wonder, how many hacks are done a day inside what seems like a safe place to grab a cup of cofee, have lunch, or meet up with friends.
