Seven Ways for hackers to use Wi-Fi to infringe your privacy

Wi-Fi-Ah, you are so convenient, but so dangerous!

Here, we will introduce seven methods and countermeasures to "generously donate" your identity information through Wi-Fi connection.

 

Use free hotspots

They seem to be everywhere, and their number will triple in the next four years. However, many of them are untrustworthy. Hackers can use the "sniffer" tool to access your logon credenemail, email addresses, and even more sensitive accounts) "Software interception-This software can intercept any information you submit through this connection. The best way to prevent hackers from being targeted is to use VPN (virtual private network), which encrypts the information you enter and thus protects your data privacy.

 

Online Banking

You may think that no one needs to be reminded not to use free Wi-Fi to operate online banking, but Kaspersky Lab, a network security vendor, says that more than 100 banks worldwide are losing $0.9 billion due to cyber hackers, it can be seen that many people are still affected. If you are sure that the free Wi-Fi in a coffee shop is formal and you want to connect to it, confirm the network name with the waiter. It is quite easy for others to set an open wireless connection in the store with a vro and set its network name as the store name.

 

Always turn on the Wi-Fi Switch

If the Wi-Fi switch on your phone is always on, you will be automatically connected to an insecure network, and you are not even aware of it. You can use location-based Wi-Fi in your mobile phone, it will automatically turn off your Wi-Fi switch after you leave the network range you saved and turn it on again after you go back.

 

Do not use Firewall

Firewall is your first line of defense against malicious intrusion. It can effectively keep your computer network open and block hackers and malware. You should always enable it unless your anti-virus software has its own firewall.

 

Browse non-encrypted Web pages

Sadly, 1 million of the top 55% websites in the world are not encrypted. An unencrypted website exposes all transmitted data to hackers. If a webpage is secure, your browser will mark it (for example, Firefox is a gray lock, and Chrome is a green lock icon ). However, even secure websites do not prevent you from being hijacked. They can steal cookies from websites you have visited through public networks, whether they are formal websites or not.

 

Do not update your security protection software

If you want to ensure that your network is protected, update the router firmware. What you need to do is go to your router Management page to check whether the latest firmware version can be downloaded from the vendor's official website.

 

Do not protect your home Wi-Fi

Needless to say, it is important to set a complex password and change the default name of the wireless connection. You can also filter your MAC address so that your router can identify only those devices that have been confirmed.
