Can Someone Hack Your Phone If You Use Their Wifi
Can Someone Hack into My Phone Through Wifi? – Xtrium
Can someone hack into my phone through WiFi? Such security concerns around smartphones are justified.
After all, our smartphones store every aspect of our lives and can pose a potential threat that can disclose our most confidential information to data hackers.
One of the many methods used by hackers includes the infiltration of Wi-Fi networks.
Yes, hackers can gain access to a mobile phone (Android or iOS) by using Wi-Fi networks. Generally, hackers use Man In The Middle attacks, aka DNS Hijacking, to infiltrate Wi-Fi routers.
They intercept communication between a user’s phone and the Wi-Fi network to access usernames, passwords, emails, and other private data.
Let’s look at several situations of how a phone can get hacked and how to secure it from malicious cyber-attacks carried through Wi-Fi networks.
How Can Someone Hack into My Phone Through WiFi?
A hacker can hack into your phone by carrying out the MITM (Man in the Middle) attack. If your home or office space uses a cable, DSL, or fiber-optic network then you must be having a router to transmit signals.
The router connects all your devices like phones, computers, smart home gadgets to the internet via the router. The process of how a hacker deploys MITM attack by using your router as the bait is quite simple:
In layman terms, this is how MITM attack takes place:
Your device connects to a Wi-Fi routerThe router relays the MAC address, which identifies your device. Each device on local network has unique MAC finds taget local WiFi router and gets access to target router’s MAC changes his device’s MAC address to make it the same as target router’s MAC, every device on the local Wi-Fi network connects to the hacker’s relays data between the router and his device, making him the Man in the Middle (MITM) this occurs, the hacker gets access to read all inbound and outbound network requests using different data collection methods.
This implies that if you type a username and password on a website or input your credit card data, it is stored on the hacker’s system.
In addition, every URL you visit is stored. All your devices connected to the hacked Wi-Fi network including your phone suffer a data breach.
It’s important to note that your phone can be hacked over any Wi-Fi network, including home and public Wi-Fi.
Note: Exercise caution when connecting to a new network since hackers leave suspicious Wi-Fi networks accessible to hack into devices and obtain access to their private information
How to Tell if Someone Hacked your Router
There are indications to look for to determine whether your router has been hacked.
You can lookout for the signs explained below to know how to tell if someone hacked your Wi-Fi:
Your Username & Password Turn Invalid
Passwords abruptly failing to work is not a good indication. When it comes to your router, this is no exception.
If your Wi-Fi network password or login credentials for the router’s admin panel no longer function, it might be an indication that a hacker has got access to your router and modified the settings to shut you out.
Unknown Device Connected To Your Wi-Fi Network
If you’re signed into your router’s dashboard, you should check the list of IP addresses that are connected to your network frequently.
If you notice an unfamiliar IP (particularly one from another country), it is most probable that a hacker has gained access to your network.
So, for our second method of determining whether your router has been hacked, look for any unfamiliar IP addresses.
How to find unknown devices connected to your Wi-Fi router:
Open a web browserEnter the IP Address of your router in the address your username and password to access the router dashboard (can be found at the back of your router) logging in, look for option that reads “connected devices” or “attached devices”Check the list of connected devices to your Wi-Fi networkIf you notice an unknown device connected to your router, ban its MAC Once you find any unknown device or notice that more devices are connected to your network than the number of devices in your home, you must take quick action.
Redirected To Malicious Websites
Another indicator of a hacked router is when you try to access your usual websites and continually get rerouted to sites you didn’t intend to visit.
This is one of the classic signs of DNS hijacking or MITM. Raise the alarm when you see this happening with clean websites that are in your frequently visited history.
Ransomware Messages
Ransomware is a form of harmful software that hackers deploy to prevent you from accessing your data in return for a ransom payment. If a hacker gains access to your router, they may easily deny access to your network.
But what if you receive an email or other form of contact from a hacker requesting cash in return for network access?
The government authorities advise against paying the ransom and suggest reporting the issue to the cyber cell of the police department.
How to Fix a Hacked Router?
If your network shows signs of being compromised, here are the steps that you need to follow for fixing it and bringing your devices back to safety.
Step #1. Disconnect from The Internet
When you unplug your router from the internet, the hacker loses access to the router because there is no longer a link.
Step #2. Reset Your Router
Your router’s settings and passwords will be reset if you do a factory reset. This gives you a fresh start with the router. To assist you with this process, there should be a physical reset button on the back of your router.
How to reset your router:
Keep your router connected to the power sourceLocate the reset button on your router. It is usually located on the back or down the reset button with a paperclip or a needle for 30 lease the button after waiting 30 for the router to #3. Change Your Passwords
Log in to your router’s admin interface after it has been rebooted and reset the password.
Please keep in mind that when you reset your router, your login details will be reset to the factory default username and password.
For reference, there should be a label on your router that lists the default username and password.
How to change router password:
Open your preferred web browser, enter the IP address of your the default username and password to log vigate to the settings Router PasswordFill in the new your When you change your password, choose a unique and complex password containing special characters like (! @#$).
You should reset the settings for your router’s admin panel as well.
Step #4. Turn Off Remote Management
Block access to your router from an outside network:
Open router’s admin to Settings > Remote off Remote Management and save the #4. Update Your Router Firmware
Routers do not usually update automatically, which is why it is critical to manually upgrade the firmware. Firmware is software that manages several features of your router and its hardware.
Upgrades are critical because they help resolve vulnerabilities, which could be a ripe target for a hacker seeking to get access to your router.
To update open your Router Settings > Firmware Upgrade > Download & Install and that’s it.
Step #5. Fixing Your Affected Phone
After fixing your router, it is time to perform some necessary checks and fixes on your phone.
Factory reset your phone by going to Phone’s settings > About Phone > Factory credentials on banking apps, social media apps, and using public portant Tips:
As you go ahead with a more security-conscious outlook, here are a few additional measures to keep a hacker from getting unauthorized access in the future:
Change your router credentials every quarterUpdate router firmware regularlyMonitor connected devices in the router dashboardUse a “guest network” for your home visitorsRead Next: Can a WiFi Router Get a Virus?

Can WiFi Provider See Your Browsing History (And How To Stop It)
One question we get constantly asked by our community is, “Can my WiFi provider see my search history? ” In this article, we want to expand on that and provide a comprehensive answer. But first things first. Yes, potentially, your WiFi provider or a WiFi owner can see what sites you ever, the ability to check what you do on WiFi depends on a variety of factors. The main ones are:Type of router you were connected toImplementation of a TLS/SSL certificate on the website you visitedPresence of an active VPN connectionLet’s also not forget that your WiFi provider can try to be using packet sniffing tools like, for example, WireShark. From that point, everything gets way trickier, and therefore we strongly recommend that you should keep your VPN on all the time. WireShark ApplicationNow, let’s dive deeper into WiFi Routers Track Internet HistoryYes, they do, though it is not common. Old WiFi routers aren’t meant to be used for Internet traffic tracking on their own, meaning one would have to have some pretty extensive technical knowledge and a set of right tools to check your WiFi history through a router. That being said, if you connect to a newer WiFi router that comes with a built-in tracking feature and pre-configured software, your browsing privacy will become very all-in-all, Internet history can be tracked on a WiFi router. But when it comes to old routers, one needs to be somewhat tech-savvy to make this happen.

WiFi Browsing History: What Can Be MonitoredUnfortunately, things that can be monitored on WiFi aren’t limited to browsing history only. There is much more what your WiFi provider can see. For example: The exact time when you connected to the InternetTime that you spent onlineTime spent on a particular websiteSpecific URLs you visited on a particular websiteUnencrypted HTTP websites dataSource & destination IP addressesHTTP vs HTTPSWhen you enter a website URL into your address bar, you may notice that each domain starts with either or. These are the two types of transfer protocols that websites and web browsers use to send and receive data packets over the web. HTTP stands for Hypertext Transfer is an advanced version of HTTP. It’s referred to as Hypertext Transfer Protocol Secure. The key difference between these protocols is the implementation of a TLS/SSL certificate on top of HTTP. The TLS/SSL certificate is a global standard security technology that allows secure communication between a web browser and a server. In other words, all the data passing through an SSL-backed website is encrypted to some extent. So, if you visit a page on an HTTPS website, your WiFi admin won’t see the content of the page and what exactly you were doing on there. However, he will still be able to see what websites you visited and what pages on those websites you WiFi Provider See Your History On A PhoneYes. If you use a smartphone to surf the Internet, your WiFi provider or a WiFi owner can see your browsing history. Except for browsing history, they can also see the following information:Apps you were usingSource & destination IP addressesUnencrypted HTTP websites dataHowever, let’s assume your WiFi admin wants to see everything you do online bad enough, and he’s invested some resources into a logging infrastructure. Then, even your delicate data can be subject to monitoring. For instance:Call & text logsText messagesVoice messagesImages or photos That’s, of course, more than enough to completely ruin your privacy and personal life. But, everything can be even worse if hackers intercept the traffic you transmit over WiFi. Then they may easily steal your account credentials, passwords, credit card details, and other valuable information no matter what device you use to access the Internet. The truth is that WiFi is flawed and, by its nature, open technology. So, unless you protect yourself with VPN encryption, you can never be confident in the security of your WiFi Owner See What Sites I VisitYes, definitely. A WiFi owner can see what websites you visit while using WiFi as well as the things that you search on the Internet. There are lots of routers with a built-in tracking feature from companies like Netgear. When deployed, such a router will track your browsing activities and log your search history so that a WiFi owner could easily check what websites you were visiting on a wireless connection. Furthermore, if this person is a tech nerd, he or she can also use special software to check your browsing history on any type of router. How To Hide Browsing History On WiFiGenerally, there are 2 ways to hide your browsing history on WiFi. You can use either Tor or a BrowserYou can use the Tor browser to hide your search history from the WiFi owner. All traffic that is routed through the Tor network is encrypted, so nobody will see what websites you were browsing. However, it’s still possible to see that you established a connection to the Tor network, and that itself may be quite suspicious. Also, Tor is really slow for things like video streaming, so you’ll be literally confined to certain activities that don’t require high-speed The other way to prevent somebody from sneakily keeping tabs on your search history is to use a virtual private network. With its help, you can anonymously browse the Internet, even if you’re connected to someone’s WiFi. That’s because a VPN assigns you a completely different IP address, hides your identity, and solidly encrypts your Internet traffic.
VPN for WiFi: Why Use It? So, there are two options: Tor and VPN. Which one is better? To find a detailed answer to this question, you can check one of our articles – Tor vs VPN. However, in case you don’t want to dig into it, here is a quick sneak peek. A VPN is much faster than TorWith a virtual private network, you can do plenty of things that require fast connection speed. For example, you can stream high-definition video without any issues since all the traffic you transmit is routed through a single high-speed tunnel. On the contrary, Tor uses several voluntarily run tunneling servers, also known as nodes, that significantly slow down your connection speed, thus limiting you to certain activities. A VPN offers better securityA VPN provides a significantly better level of protection than Tor does. Firstly, it masks your IP address and protects your online traffic with a hacker-proof AES-256 encryption. Secondly, it keeps your data protected all along the way until it hits the destination point, whereas Tor decrypts data packets coming out of the last node. Paid VPNs also provide advanced security features such as Kill content is accessibleA VPN allows you to choose one server from a pool of servers located in all corners of the world, making it possible for you to access any content you want. As for Tor, it will randomly pick a couple of servers from its global network. In the vast majority of cases, these servers won’t match the ones you need to uncensor your favorite websites. Wrapping Things UpHopefully, we’ve managed to elaborate on the topic and provide you with the information you were looking for. Here is a short summary of the article:Your WiFi provider can see your browsing history on any deviceOne can see your browsing history on all types of routers if he wants it bad enoughExcept for search history, there are other sensitive data that can be monitoredYou can hide your WiFi history by using Tor or a VPNVPN is a better choice than Tor if you want to be confident in your online privacy and securityStay protected!
How hackers could use Wi-Fi to track you inside your home
As connected devices such as voice assistants, security cameras, and smart appliances grow in popularity, the homes and offices where they are installed become increasingly filled with a dense web of Wi-Fi signals.
A new study from University of Chicago and University of California, Santa Barbara researchers finds that external attackers can use inexpensive technology to turn these ambient signals into motion detectors, monitoring activity inside a building without being detected themselves.
With only a small, commercially available Wi-Fi receiver, an attacker from outside the target site can measure the strength of signals emitted from connected devices and monitor a site remotely for motion, sensing whether a room is occupied. The research, led by leading UChicago computer scientists Heather Zheng and Ben Zhao, reveals the technique of these attacks as well as potential defenses.
“It’s what we call a silent surveillance attack, ” said Zheng, a Neubauer Professor of Computer Science at the University of Chicago and expert on networking, security and wireless technologies. “It’s not just about privacy, it’s more about physical security protection. By just listening to existing Wi-Fi signals, someone will be able to see through the wall and detect whether there’s activity or where there’s a human, even without knowing the location of the devices. They can essentially do a monitoring surveillance of many locations. That’s very dangerous. ”
The research builds upon earlier findings that exposed the ability to “see through walls” using Wi-Fi signals. However, previous methods detected indoor activity by sending signals into the building and measuring how they are reflected back to a receiver, a method that would be easy to detect and defend against. The new approach requires only “passive listening” to a building’s existing Wi-Fi signals, does not need to transmit any signals or break encryption, and grows more accurate when more connected devices are present, raising significant security concerns.
“The worrisome thing here is that the attacker has minimal cost, can stay silent without emitting any signal, and still be able to get information about you, ” Zheng said.
Connected devices typically do not communicate with the internet directly, but do so by regularly transmitting signals to an access point, a hardware device such as a router. When a person walks nearby either device in this conversation, it changes the signal subtly, such that the perturbation can be detected by a nearby receiver “sniffing” the signal. That’s enough information for an observer to know if a person (or large animal, the researchers add) is in the room, with very high accuracy.
Because most building materials do not block the propagation of Wi-Fi signals, the receiver does not even need to be in the same room or building as the access point or connected devices to pick up these changes. These Wi-Fi sniffers are available off the shelf and inexpensive, typically less than $20. They’re also small and unobtrusive, easy to hide near target locations, and passive—sending no signal that could be detected by the target.
The researchers also suggested different methods to block this surveillance technique. One protection would be to insulate buildings against Wi-Fi leakage; however, this would also prevent desirable signals, such as from cellular towers, from entering. Instead, they propose a simple technical method where access points emit a “cover signal” that mixes with signals from connected devices, producing false data that would confuse anyone sniffing for Wi-Fi signatures of motion.
“What the hacker will see is that there’s always people around, so essentially you are creating noise, and they can’t tell whether there is an actual person there or not, ” Zheng said. “You can think about it as a privacy button on your access point; you click it on and sacrifice a little bit of the bandwidth, but it protects your privacy. ”
Zheng hopes that router manufacturers will consider introducing this privacy feature in future models; some of those firms have announced new features that use a similar method for motion detection, marketed as a home security benefit. The UChicago research has already received attention from Technology Review, Business Insider and other tech publications, raising awareness of this new vulnerability.
The study also reflects a growing research area in the Department of Computer Science, examining issues around increasingly prevalent connected “Internet of Things” devices. The IoT Security and Privacy Group, which includes Zhao and Zheng and additional faculty members including Nick Feamster, Blase Ur, and Marshini Chetty, will investigate both the benefits and potential vulnerabilities of these technologies, and a new IoT Lab in the Center for Data and Computing provides devices for researchers and students to hack and study for research.
The paper also includes co-authors Zhujun Xiao, Max Liu, and Yuxin Chen of UChicago CS, as well as Yanzi Zhu and Zhijing Li of UCSB.
