Tool to detect fraudulent WiFi hotspots, avoid revealing personal information

Using public WiFi exposes users to many risks of personal information being compromised. Hackers will monitor and interfere with the incoming and outgoing connection data on your WiFi-connected device. It can also direct users to malicious websites to steal financial information or install malware on the device for remote access.

You should avoid accessing networks without passwords and sending data out unencrypted, as this data can be easily collected by bad guys. Here is a tool to detect rogue WiFi hotspots.

According to security researcher Tom Neaves (Trustwave company), spoofing MAC address and SSID (network name) in public places is relatively simple. Then the phone will automatically connect to WiFi if the user has been to these places before.

Researchers have now successfully developed a tool to solve this problem, helping users easily detect rogue WiFi access points by comparing the current access point information with the previous one. The new tool, called Snappy, can detect rogue WiFi access points that are spoofed to steal data.

By analyzing, Tom Neaves found some characteristic elements of the access point (which do not change over time), such as the provider, BSSID, supported speeds, channel, country, maximum transmission power and some other factors.

The researcher uses the signature function to generate a unique signature for each access point. This signature can be used by a scanning tool to generate matches and mismatches.

If the information matches, this means that the access point is the same as the last time. On the other hand, if the information does not match, it means that something has changed and the access point the user is connecting to may be fake.

You should note that when you turn on the device and look in the list of captured WiFi networks, there are many different names. Only choose networks that you know clearly and belong to a specific company or hotel. You should not connect to strange WiFi networks without password protection, even if that network has better transmission quality than the one you usually use.

At the same time, absolutely do not use public WiFi to buy or sell anything related to personal accounts. This will be the main reason why you can lose your bank account or other important network service accounts.

In addition, you should not use the same password on many important services at the same time because if you expose one account, hackers will quickly test those accounts to control your mailbox.

In the age of technology, don't be subjective when using public WiFi, because sometimes just a small mistake can cause your personal information to be stolen.
