Owen said, "First of all, hackers will implement middle attack, copy all traffic between the device and the Internet, although some traffic may be encrypted - If the user when accessing the website using HTTPS, but quite a lot of data is still readable. ”

Once invading user equipment, hackers can do whatever they want. Davis said that "hackers can use this connection to infiltrate user devices, access files, inject malicious pieces, and perform other malicious acts."

Mimecast network strategist Orlando • Scott - Cowley (Orlando Scott-Cowley) said, "In the attack, the hacker can easily detect the user's personal information, applications and services used, as well as the type of device." Once users get these Information, hackers have mastered the key to enter the user's "kingdom", and may sell this information to any person or organization willing to pay high prices.

The following are the findings of Avast's use of fake WiFi hotspots: 38.7% of users have installed Facebook or Facebook messaging applications; 13.1% have access to Yahoo emails, and 17.6% have access to Gmail; 13.8% use Chat applications such as WhatsApp, WeChat or Skype. If the attack is successfully implemented, hackers may gain access to these systems.

This is obviously not good news for users, but if users use work equipment and store sensitive information, the loss will be even greater.

solution

For users who travel frequently and need WiFi during their trip, Davis recommends purchasing their own hotspots. In this way, the user knows the device to which he is connected, and can use it anytime when needed, without having to rush to use potentially insecure connections.

If you choose public WiFi, Davis recommends choosing a network that does not require registration and does not make any financial transactions through the connection.

Orlando said that if it supports 4G, users can use the phone as a hotspot and connect faster than some free WiFi networks.

Scott Cowley said that if a user uses a WiFi hotspot that looks like a geographical location - for example, the name of the user's coffee shop, he can ask the waiter to check if there is a problem with the WiFi hotspot.

PCWorld claims that even if it is not traveling, users should be careful that their computers automatically log in to any public WiFi network. Users may always work at Revolution Roasters, using their WiFi network. Owen said that hackers can establish a WiFi with a similar name, and the user's computer may not be able to distinguish between the two.

VPN (Virtual Private Network) protects the information transmitted between the device and public WiFi. Irving recommends that users protect their physical devices. Sometimes it’s easier to get in touch with a device and install malicious pieces than to connect via the Internet.

Owen said, "Travelers should be aware that hackers will steal their laptops, tablets and phones. In addition, users should not be inserted into the CD-ROM from unknown sources on the device, hard disk or U disk, hackers may put these things deliberately 'lost' In public places, entice users to insert them into their equipment.”

Therefore, if the mobile storage device is suspected to be from a travel agency and contains information that promises to be discounted, it should not be inserted into its own device because the user does not know its true source.
