These Are the 5 Biggest Wi-Fi Security Risks
Think you're protected while using the public Wi-Fi hotspot at your favorite café or restaurant? Think again! Keep reading to learn the risks.
The public Wi-Fi of 2017 is much improved from the era of unprotected, vulnerable WLAN Internet. However, your Wi-Fi could still be compromised if you’re unlucky or careless while using public or private Wi-Fi. So, it’s important to stay armed against potential security breaches. One way to check the security of your Internet, whether you’re on a public or private network, is to use the Wi-Fi Check feature:
- Unsecured Networks
Public Wi-Fi hotspots aren’t always properly secured. Never join an unknown open network just because it’s available to anyone. If you don’t know who is providing a Wi-Fi connection, you shouldn’t be using it; end of story. Unsecured networks are far more vulnerable to an attack, and you could be walking right into a hacker’s trap.
- Data Interception
Data interception is a serious risk if you’re using public Wi-Fi, or an older WLAN format like TKIP. The most common form of data interception is known as Man-in-the-Middle (MiM). During MiM, a hacker is latching onto data packages as they travel between two Wi-Fi users. This attack is also sometimes referred to as “eavesdropping.”
- Denial of Service (DoS)
WLAN Internet connections are often targeted by Denial of Service (DoS) attacks. A DoS attack occurs when a malicious party floods an Internet network with unwanted traffic. This surge in traffic levels often makes the network unresponsive to legitimate users, thus preventing them from establishing an online connection.
- Wireless Phishing
Hackers are always developing more advanced methods to steal personal information, including wireless phishing. One type of wireless phishing attack is carried out by infecting a user’s browser cache. If a hacker successfully breaches a web session in-progress, they can redirect that user to phishing websites, even after the user leaves the Wi-Fi hotspot.
- Rogue Access Points
Thankfully, rogue access points aren’t nearly as common as they used to be. Still, these unauthorized APs do pose a security threat. What is a rogue AP? It’s an access point that’s installed into a Wi-Fi network. Usually, these APs are meant to give clients better accessibility to the Internet, but the wireless router has been poorly configured. A vulnerable router is prime bait for hackers to break into.
