FBI warns all users not to connect to WiFi provided in public places when they go out

The FEDERAL Bureau of Investigation (FBI) has also issued a notice on its official website advising users not to connect to public WiFi when they go out. The idea of not connecting to public WiFi was not the FBI’s first, but it is still valid today and should be heeded by all. The FBI says don’t let your computer, phone, tablet, or other device automatically connect to those free public WiFi networks when you go out.

This can pose a potential security risk to you, as hackers can use these public WiFi to sniff connected devices and intercept traffic.

Why not use public WiFi:

In the tip, the FBI says connecting to public WiFi is the equivalent of a user sending a public invitation to a hacker inviting those with bad purpose stogmers to access their devices.

Hackers can naturally connect when users connect to free public WiFi, and they can use the opportunity to launch attacks while they are in the same local area network.

The FBI says hackers can send malware to user devices through a local area network, steal a user’s account password, and even remotely turn on a camera and microphone.

Of course, the FBI may be a little alarmist to professionals, but it’s hard not to mention that hackers do have a way of reaching such an attack.

In fact, this type of attack mainly relies on LAN man-in-the-middle hijacking and the exploitation of the device’s potential vulnerabilities, no one can guarantee that their devices are completely free of vulnerabilities.

HTTPS is a good approach but not enough:

Man-in-the-middle hijacking of such attacks does not directly affect connections encrypted through HTTPS, and unfortunately there are still a few services connected via HTTP.

A hacker can hijack a connection through a clear text HTTP protocol and even replace some files with specially crafted malicious files when they download them.

The FBI also says the HTTPS protocol doesn’t fully guarantee security, because if you’re connected to a phishing WiFi owned by a hacker, hackers can decrypt traffic.

Of course, there is a case where a hacker who breaks into and controls some public WiFi routers can also decrypt HTTPS traffic to steal content.

Full use of traffic Internet access? I can’t do it!

The FBI’s advice is not to connect to any public WiFi, including public places such as shopping malls or even hotel wireless networks, and to use cellular traffic instead.

Although from a security point of view this is a very pertinent proposition, but the full use of cellular traffic internet access, perhaps the vast majority of users can not do it for a long time.

Especially in the hotel if you want to see streaming video or live or turn on the computer to handle office affairs, simply rely on traffic internet estimates will be stressful.

However, turn off WiFi on your smartphone or tablet when you’re away and off the house, prevent automatic scanning of WiFi connections or revealing MAC addresses.
