This foreigner is probably talking about something that happened several years ago. .

1. Take advantage of the "unencrypted communication" feature between the wireless LAN router and the PC

Nowadays wireless routers basically support encryption. If the wireless network you use is not encrypted, Well, no foreigner needs to tell you, Windows will warn you that this connection is unsafe.

Taking a step back, even if your link layer is not encrypted, some online banks now support https connections, so when you connect to an https website, the communication between you and the server is encrypted.

Taking a step back, even if your network layer is not encrypted, most websites will require you to install a certificate, which is to digitally sign the communication between you and the server.

So it is basically impossible to obtain your online banking account number and password from wireless communication. Of course stallions can, but that’s another question

2. “Search for certificates from the other party’s computer”

The prerequisite for “Search from the other party’s computer” is to hack into The other party's computer, the so-called hacking into other people's computers and catching unsuspecting chickens is one thing, but hitting them wherever you point them is another matter. What's more, a PC doesn't want a server, doesn't open too many ports, and doesn't matter what advanced preventive measures you take. As long as the anti-virus software is updated regularly, system patches are kept up, and the admin password is not left blank, your computer cannot be hacked by ordinary hackers. of.

But to be honest, if you really want to steal your online banking account password, this may be the easiest part to start with.

In short, what this foreigner is talking about is a situation where there are no preventive measures. The ideal situation is that in reality, as long as you are not too lacking in precautionary awareness, you usually don’t have to worry about this issue.

However, it is true that wireless networks do have certain security risks, because anyone can access them and capture packets.

So try to choose an encrypted wireless network. If it is your own router, you can also limit the mac addresses that are allowed to connect
