You've got a free wifi every day, and you've probably got someone behind you to intercept your account code. The more common wifi is, the less people talk about the security of the wifi hotspots, the more the vast majority of people step on the pit without knowing that they are being stolen。
Fake free wifi
Criminals present a hot spot in front of malls and cafÉs with one or two letters, such as starbucks next to starbucks, with a password left blank or placed in 12345678, which is specifically connected to guiders. Even after he hijacked the dns on the router, every account you lose, every password you pass first. In 2024, an online police officer at a certain location reported that a group had stolen over 30,000 entries for six months。

The more subtle way to play is for some groups that do not work on fishing sites and directly monitor all traffic from your mobile phone on their routers. You log in, cell phone bank transfers, fill out a delivery list, the password is all over the phone, and he recorded it. You don't know the whole thing, you don't have any unusual hints on the screen, you think you're connected to a normal network, and all the data is turned around。
A few moves by wifi in public
Go to the coffee shop and the hotel lobby and ask wifi what his name is. The more you turn out, the more you look like a real card, the more alert you are. Public hot spots without passwords, especially those such as "cmcc- "free-wifi", are the most likely to be implanted into malicious programs, and you are connected to an active back door。
Before opening up payment software or bank ap, turn wifi off to the operator's 4g or 5g traffic. It doesn't matter if you spend dozens of mega-flows, but your transaction data go by the encryption channel, which the middleman can't even intercept. This habit is extremely low-cost and takes two more seconds to cut the network, blocking the way in which the vast majority of paid information is stolen, which is more useful than the installation of any security software。
The real cost of setting the router

Many people buy a router with their home or office, the password is the default admin for the factory, and the certification agreement is wep. Wep was broken with scripts for five minutes back or later in 2005 and is still in use. A private router in the company is not available, which is tantamount to opening up the intranet door, with customer information, financial data, core code running in an unprotected section。
In 2023, an incident occurred in a manufacturing company, where a department chief had a private router in the office area without authorization or network segregation, outside assailants went directly into the inside of the network, dragging production data and supplier proposals for two months. Finally, it was calculated that compensation was awarded for the loss of more than eight million dollars due to the shutdown. An unauthorized router lost the company's profits for most of the year。
The router's security is not being saved
The certification agreement had to choose wpa2, wep and wpa. Hide sid, not allow router names to be shown in the search list, then bind the device mac address that allows access, and no stranger even guesses the password. The password is at least eight, size plus numbers plus markers like ab3#xk9。
To add a wireless router to the corporate office network, the it approval process must be followed to separate the network from vlan and ensure that wireless equipment and core business networks are not in the same broadcast area. Many people took it on themselves because of the difficulty of the process, as a result of which a single terminal was infected, the entire sector network was paralysed for three days, overtime repairs and the loss of business was much more than the equipment that had been saved。
Wifi's blind zone

You were in a milk tea store last year with "mixue-store" and the password was stored. This year you passed another store with the same name and the phone was automatically connected. The hacker ate the same thing, set up a hot spot with the same name in a crowded area, and hundreds of mobile phone murmurs came up, and he ran through the data in bulk on the backstage。
The wifi is not normally used to turn off the wireless lan switch on the cell phone and notebook, so that it does not search the backstage itself. Right? And those wifi-keys-apps, whose backstages keep passing the hot-spot codes you've been passing on to its servers, are the same as taking photos of the home keys to strangers, and offloading them as soon as they can。
Back off the pit vent
In public, even wifi, name check with the merchant. No hot spots without passwords, transfer payments cut cellular data. Home and office routers, wpa2 strengthen passwords and mac bindings and complete basic security in three steps. Wifi didn't have to turn it off, the almighty key off, heard a friend say, "i'm connected to a free internet," and remind him to read his name。
These are really not complicated, but less than 20 per cent can be achieved. You could have someone staring at your screen backstage behind every free hotspot. Wifi hot point information security is not something that can be solved by technocrats. It takes you three more seconds each day to confirm a name, and it's a habit that works better than 10 safe apps。
Did you check your name first? The comment section talks about the pit you've stepped on or almost stepped on, but if you think it's useful, then you can give it to your elders, and one more person knows that only one person is stolen。
