How to Protect your Wifi From FragAttacks and Attackers? FragAttacks is a set of security vulnerabilities that can be used to attack WLAN devices. Just as all Wi-Fi devices created before have vulnerabilities, attackers can steal sensitive data or attack network devices.
Here you can learn how to protect your Wifi from FragAttacks and attackers. But first, let us know some basic information about FragAttacks.
What are FragAttacks & What Can Attackers Do with it?
The term FragAttacks was released on May 12, 2021, and stands for fragmentation attacks and integration. This is a collection of vulnerabilities that have been jointly disclosed. Three of them are the design flaws of Wi-Fi itself, which will affect most devices that use Wi-Fi.
Researchers have also found programming errors in many WLAN products. Cybercriminals are easier to exploit than the design flaws of the wireless network itself.
An attacker can use FragAttacks to do one of two things. On the one hand, through FragAttacks, it may steal data from WLAN networks, and it is also encrypted to prevent such attacks. (Websites and applications that use HTTPS or other types of secure encryption can resist these attacks, but they send unencrypted data over an encrypted Wi-Fi network. Connect to a Wi-Fi network. If so, you can use FragAttcks to use Wi -Fi encryption to prevent this from happening.
Secondly, researchers are mainly concerned about the possibility of using FragAttcks to attack vulnerable devices on Wi-Fi networks.Unfortunately, many smart home and IoT devices, especially those of strange flying brands that do not provide long-term device support, are not regularly updated. Cheap smart plugs and smart bulbs from unknown brands are vulnerable to attack. Theoretically “not important” because the device is on a trusted home network. However, FragAttacks allows an attacker to bypass the security of your Wi-Fi network and directly attack your device as if it were connected to the same Wi-Fi network. -Wi.-Fi is used as a network device.
Which Devices are Vulnerable to FragAttacks?
Researchers said that all Wi-Fi devices created so far may be affected by at least one FragAttack vulnerability, which means that any Wi-Fi device that first launched Wi-Fi in 1997 may be attacked.
The news is that this vulnerability was discovered nine months before its release. At this time, many companies have issued security patches to protect their devices from FragAttacks attacks. For example, Microsoft updated Windows with FragAttacks protection in an update released. March 9, 2021
What’s the Actual Risk FragAttacks?
First, with an attack on Wi-Fi, the attacker must be physically close to the wireless range of the network, i.e., to execute an attack using FragAttacks. That is if you are in apartments and dense urban areas, the risk of increasing the number of people nearby increases somewhat. If you live in a place where no one else is present, you are unlikely to be attacked.
Corporate networks and networks of other institutions that can be the target of high value are also clearly at higher risk than the average home network.
At the time these flaws were revealed in May 2021, the researchers said there was no evidence that one of these flaws was being exploited in the wild. So far, they seem like a simple theoretical problem, but when they become public, they increase the risk of people using them to attack real networks.
So FragAttacks is a problem, but there are no “wormable” attacks that can spread like wildfires over the Internet. An attacker can attack a smart home device or capture sensitive information by being close to the user and attacking the network. data. Of course, device manufacturers need to expose this flaw and issue software patches for existing devices to protect future devices. And there are some things you can do to protect yourself.
How can you protect your Wifi from FragAttacks?
Thankfully, standard best practices for keeping your devices and networks safe can also help to protect your Wifi from FragAttacks and attackers. Here are 3 ways which can help you to protect your Wifi from FragAttacks and attackers.
1. Use secure encryption
Make sure you visit the HTTPS site when you log in. Try to use HTTPS whenever possible. Browser extensions such as HTTPS Everywhere can help, but you don’t need much, because if HTTPS is available on most websites, they will most likely be used automatically. Firefox can be configured to warn before loading unencrypted HTTPS websites. Also try to use strong encryption everywhere. Although you can transfer files between devices on the local network, please use an application that provides encryption to ensure the security of the transfer.
You can track user FragAttacks and other potential crashes by bypassing Wi-Fi encryption. VPNs can of course route all traffic through an encrypted connection, so you can visit the HTTP website you are currently using (or any other unencrypted service). If you are disturbed by the network currently in use, they can provide additional protection against Frag attacks.
2. Scan for security updates constantly
Make sure your device is checking for security updates. If you’re still using a Windows 7 or earlier macOS computer that hasn’t received the update, you’ll need to update. If your router is too long and the manufacturer does. Don’t upgrade your router, you need to use a new router. If the firmware update does not apply to smart plugs and other old devices, and there may be security vulnerabilities, you should replace them with new ones.
3. Install these security updates
Recent devices usually install updates automatically. However, some devices, such as routers, require you to agree to the installation of those updates by clicking an option or pressing a button.
That’s it: To protect your Wifi from FragAttacks and attackers, please use a device that receives updates, install security updates, and use encryption when connecting to websites and transferring data. Fortunately, FragAttacks has not yet been used in the wild.
Those who manage the security of an enterprise’s IT department have a lot of work to do to ensure that their infrastructure is not prone to these errors.
