Is Someone Hacking My Wifi

Peripheral Devices Dont Work Properly

How to Tell if Your Wi-Fi Network Has Been Hacked

The presence of a virus or a hacker affects not only your computer but all devices connected to it. So, if your printer suddenly doesnt print files or you cant open your USB device, something might be amiss. Run a full scan of your system and look for any new software that you havent installed.

If you cant find a problem, the issue might be with the peripheral device or the hacker has covered his traces well.

Antivirus Program Is Turned Off

Think about your antivirus as a shield, which protects your laptop from malicious threats, viruses, and dangerous website. Under no circumstance should you ever turn it off because youll be vulnerable and an easy target. Thats why when hackers breach your computer, the very first thing they might do is disable your antivirus so that it cant warn you that something unusual is happening.

But couldnt I have switched my antivirus off without realizing? Thats unlikely. Try to turn it off, and youll immediately get a warning, and youll be asked whether you want to disable it. My point is that its not something that can happen with one click of the mouse. And if a program wants from you to turn off your antivirus or firewall, it should raise the red flag that something is not right.

So, if you notice that your antivirus is not running, youre almost 100% hacked. The first thing you should do is to try to get your antivirus working again. If you cant do it, it means that the infiltration is serious. You can attempt to install a new antivirus or restore your computers setting to a point before the breach.

You can also switch your computer in Safe mode and see if you can get things running. However, if you dont know what youre doing, its for the best to get a professional to fix your computer, especially if you have important files which you have not backed up.

Never Use Hidden Networks

A normal Wi-Fi access point will send beacons containing all the information needed for nearby devices to discover and connect to it, such as the network SSID and supported encryption. Hidden networks, by contrast, never send beacons and dont announce themselves in any way, requiring that a client device to be in range and already know about the network to connect. That means youll never see a hidden network included in the list of nearby access points, making it harder in theory for an attacker to know a network is there. Some users think that security by obscurity is a good way to hide their network from Wi-Fi hackers, but the ironic truth is that by hiding your Wi-Fi network, you make all of your smart devices easier to track. Because a hidden Wi-Fi network will never broadcast before a device tries to connect to it, a Wi-Fi device configured to connect to a hidden network will have to assume that the network could be nearby at any moment. In practice, that means that your device will be constantly calling out the name of the network youve hidden, making it easy to track your Wi-Fi device even if the MAC address is randomized or youre taking other precautions to stay anonymous. Not only does this make it easier to trick your device into connecting to a rouge AP, it also allows anyone to track your presence by the radio signals your smart device is constantly sending.

How Can I Detect Who Is On My Wifi

How to DOS any WiFi network

By far the simplest way how you can answer yourself the question Whos on my WiFi? is by checking your routers logs. Virtually all routers keep some sort of a record of past and current connections, usually stating both the IP address of every connected device and its name.

If you notice that an iPhone 8 is connected to your home wireless network even though you dont own a single Apple device and are sure that neither do your friends and family, its possible that the iPhone belongs to someone who has no business being on your network.

If your router allows you to disconnect a connected device from the admin interface, dont hesitate to do so. Just remember to also change your password otherwise the intruder might reconnect the second you go back to minding your own business.

Wifi Security Is Important

Recently, two Belgian researchers discovered a critical vulnerability in the Wi-Fi Protected Access II implementations on most wireless networking devices that use the protocol. The name of this vulnerability is KRACK , and it allows attackers to steal sensitive data, including passwords, credit card numbers, or chat messages.

According to Wired, Security analysts say its a tricky vulnerability to take advantage of, and major platforms like iOS, macOS, and Windows are either unaffected or have already been patched. But given the millions of routers and other IoT devices that will likely never see a fix, the true cost of KRACK could play out for years.

What Are The Signs Of A Hacked Wifi

Wifi can be accessed by almost every device in the modern day: a smartphone, tablets, PCs, and laptops. To know whether someone has been tampering with your personal wifi there are certain signs that can prove it. The most common sign and the most obvious one is that a hacked wifi always makes the internet connection a lot slower, as someone else might be using your wifi to surf the web. Another sign to look out for is to check if the routers activity is still blinking after turning off of the devices in your house that are using wifi. If the light still continues to blink, it means that some unauthorized person is using your wifi.

Your Friends Receive Social Media Invitations From You That You Didnt Send

Weve all seen this one before. Either you or your friends receive invitations to be a friend when you are already connected friends on that social media site. Usually, youre thinking, Why are they inviting me again? Did they unfriend me and I didnt notice, and now they are re-inviting me. Then you notice the new friends social media site is devoid of other recognizable friends and none of the older posts. Or your friend is contacting you to find out why you are sending out new friend requests. In either case, the hacker either controls your social media site, has created a second near-look-alike bogus page, or you or the friend has installed a rogue social media application.

What to do: First, warn other friends not to accept the unexpected friend request. Say something like, Dont accept that new invitation from Bridget. I think shes hacked!. Then contact Bridget some other way to confirm. Spread the news in your common social media circles. Next, if not first, contact the social media site and report the site or request as bogus. Each site has its own method for reporting bogus requests, which you can find by searching through their online help. Its often as easy as clicking on a reporting button. If your social media site is truly hacked , youll need to change your password .

Consult Your Router Settings

How to find out if someone is hacking your wifi and How to block that device ||Computer Support||

If you’re lucky, you’ll be able to recognize all the items on that list, but there may be a few that don’t have enough information. After going through my list, for example, I was left with a couple devices that listed no name and no manufacturer. However, I was able to get a little more information from my router’s web interface.

You can open your router’s management page by typing its IP address in your browser’s address bar. Once there, look for an option that sounds like “Attached Devices” or “Client List.” This will present you with a similar list as Wireless Network Watcher, but the information may be slightly different. After cross-referencing the unknown devices between the two, I found one of them was listed as “AzureWave Technology, Inc” in my router’s interface, but not Wireless Network Watcher. A little Googling revealed that this was my Rachio sprinkler system, so I was able to mark that down and move on.

If you see any other unlabeled devices in the list, check around your house for any internet-connected gadgets you might have missed. I realized that my wasnt listed, so after checking the Alexa app on my phone, I was able to match its MAC address to one of the unlabeled items in Wireless Network Watcher.

Power Cycle Or Reset Your Router Or Wireless Gateway

In some router hacking cases, a simple power cycle works as a quick fix. This method clears the memory of any malicious code and refreshes your public IP address. Just pull the plug, wait 30 seconds, and then plug the cord back into the outlet.

In other cases, you may need to reset your router to its factory settings if an infection persists or you cant log in. A power cycle cannot remove severe infections like VPNFilter.

To factory reset your router, find its reset buttonits either surface-mounted or recessed on the back. Press and hold the buttonyoull need a paperclip for a recessed buttonfor 10 seconds until your routers LEDs indicate a reboot.

Change Your Routers Network Name

While youre configuring your router changing your admin credentials and setting a strong password change the SSID as well. SSID stands for service set identifier, which, in everyday terms, is the name of your Wi-Fi network.

New routers often display the brand of the router in the SSID, and Wi-Fi hackers can use that information to help them crack your password. Set a custom network name instead so that they wont know which type of router you have. The more clues you give a hacker, the easier their job will be.

Get creative with your Wi-Fi network name: make it long and complex. WPA encryption uses the SSID as part of the algorithm, so by avoiding default or common network names, youll make your network more resistant to password cracking methods like rainbow tables. Besides, its fun to give your neighbors something to chuckle about.

You Cant Log In To Your Router

You should worry about a possible hack if you cant log in to your router or wireless gateway. Typically, routers ship with default login credentials you can use to access the settings. Youre supposed to change these credentials during the initial setup process .

However, if you cant log in to your router using the credentials you created, theres a possibility that its hacked. Someone may have figured out the credentials, logged in, and changed the password to lock you out. After that, a hacker has free reign to change additional settings and make your life miserable.

Issues with your routers firmware can cause login problems, too, and if your network is behaving normally but you just cant log in, its probably not compromised. In any case, youll need to reset the device to fix it.

How Router Hacking Works

how to

Depending on the router you have and how well youve secured it, aspiring Wi-Fi hackers can try one of several attack methods to breach your router security.

Using the default login credentials: This is the easiest way to hack someones router. If youve never changed your routers admin password, anyone can simply log in with that information. Router hackers know the standard passwords for the most popular routers, and theyll happily try these out on your Wi-Fi network.

Exploiting a firmware vulnerability: Firmware is the name for built-in software that tells a hardware device, such as your router, how it should work. Software vulnerabilities are security flaws that hackers can exploit in their attacks. If your routers firmware has a vulnerability, a router hacker can leverage it to access your routers administrative settings. Regularly check your router manufacturers website for firmware updates, and install any that you find.

Cracking your password: Changing your router password might not be enough to keep a hacker out. By trying one password after another, hackers can keep guessing until they land on your password. The simpler your password, the easier this becomes so always create strong and unique passwords for all your devices and accounts.

Still wondering if a router can be hacked? Given enough time and resources, any device can be hacked. Thats why effective internet security means making the hack as difficult and time-consuming as possible.

Vulnerabilities In The Software

Your operation system might have vulnerabilities which hackers can exploit. Developers try to come up with a solution as soon as they discover one, but hackers are usually faster. A weakness in the OS can allow hackers to install backdoors, encrypt your files, or steal information. Thats why you should always keep your software up to date.

Create A Strong Ssid Network Name And Pre

You will also need to make a strong SSID . If you use the router’s default network name , then you make it easier for hackers to hack your network. Using a default SSID or a common one helps hackers crack your encryption because they can use prebuilt rainbow tables associated with common SSID names to crack your wireless encryption.

Create a lengthy and random SSID name even though it might be hard to remember. You should also use a strong password for your pre-shared key to further discourage hacking attempts.
