How To Hack An iPhone Through Wi-Fi

Have you ever wondered whether someone could hack your iPhone, and occasionally your interest grows to the point where you wonder if you can hack an iPhone yourself? Hacking an iPhone is feasible. Technically, every networked digital technology can get hacked. When Apple boasts about how difficult it is to hack an iPhone, it refers to the iOS code and security features. On the other hand, a human mistake has long been the primary source of data breaches worldwide.

When it comes to iPhone hacking, most approaches consider the user, not the operating system, as the weak link in the security chain. You may make it difficult for anyone who has no permission to use your phone by being aware of the most efficient techniques of influencing people like yourself. Apple noticed a severe security flaw in an iOS feature in early 2020, letting hackers take total control of any iPhone within the Wi-Fi range.

How To Hack An iPhone Using Wi-Fi 

Hacking is breaking into electronic equipment, analogous to theft, but digital. While it may appear unethical or immoral, there are certain advantages.

Governments and the FBI use legal hackers to combat illicit hackers attempting to steal information. They also break into terrorists’ and others’ iPhones to acquire necessary information.

Using a public Wi-Fi connection is the top way to get into an iPhone. Public Wi-Fi is incredibly dangerous and insecure. You can more or less get the target data if you know what you’re doing. It is, nevertheless, complicated to understand. As a result, you’ll require a lot of technical knowledge.

Researchers looking into a flaw that caused the Wi-Fi service on iPhones to crash discovered that it could get used to executing code remotely without the user’s knowledge.

Carl Schou discovered the flaw after connecting his iPhone to a network with the SSID “%p%s%s%s%s%n,” resulting in the device losing its Wi-Fi connection capability. Various string variants caused the Wi-Fi service to fail and enter a restart cycle. According to tests conducted by security experts, the vulnerability found by Schou may be exploited in iOS 14.6 when connected to a maliciously constructed SSID.

Resetting network settings to remove the names of all Wi-Fi networks, including the infamous one from the list of known SSIDs it might join, was all it took to fix the situation.

However, researchers at mobile security firm ZecOps discovered that this weakness is more than just a Wi-Fi denial-of-service (DoS) problem.

The researchers said that the flaw may get triggered with a zero-click (no user engagement) and lead to remote code execution on specific iOS devices.

According to ZecOps, the problem is analogous to a format-strings flaw, where the computer interprets an input value as a formatting character rather than a character. Wi-Fi Demon was the name given to this assault.

“However, this problem differs from “typical” print format string bugs in that it makes use of [NSString stringWithFormat:], which Apple developed, and Apple eliminated support for percent n for security concerns,” ZecOps notes.

The researchers utilized “% @,” a format specifier for printing and formatting objects in Objective-C, the programming language for iOS apps while trying to discover another way to attack the problem

When the researchers merely added “% @” to the name of an SSID, they were successful. Creating a malicious Wi-Fi network and waiting for the victim to connect is one scenario that might result in malware executing the target device.

If the Wi-Fi connection is enabled and the auto-join feature switched on, which is the default state, one scenario creates a malicious Wi-Fi network and waits for the target to connect.

The Wi-Fi service fails and restarts in a cycle after receiving the malicious SSID information on previous iOS versions, even if the user does not join the malicious network.

If the problem gets exploited locally, a hacker might use it to create a partial sandbox and jailbreak the device.

Although ZecOps found no proof of Wi-Fi Demon attacks in the wild, the company believes that some malicious hackers may have identified the flaw and may use it.

The researchers say Schou’s vulnerability may be exploited in iOS 14.6 while connecting to a maliciously constructed SSID.

To guard against Wi-Fi Demon assaults, the researchers advised updating the phone’s operating system and removing the auto-join option in Wi-Fi settings, which can also protect against beacon Ip spoofing that overwhelms the device with access points connection.

Apple has been working on a cure in recent iOS 14.7, but these attacks are new and might grow more popular given their covert nature.

These are the sites where we most frequently come across dodgy Wi-Fi networks:

1. Airports: Many airports in the United States provide free public Wi-Fi to travelers. These networks are basically like any other public Wi-Fi network in terms of security. Any Wi-Fi network that requests extensive personal information or gets run by a third party raises even more red lights. 

2. Budget Hotels And Motels: Maintaining a sizeable Wi-Fi network with hundreds of unique users and private connections is expensive; many low-cost hotels use a single open network.

3. Cafes And Bars: Coffee shops are practically associated with “free Wi-Fi.” While the Boingo pop-up at the airport may have heightened your defenses, we’re willing to bet you no longer hesitate to connect to Starbucks’ Wi-Fi.

How To Avoid The iPhone Wi-Fi Threat

If your iPhone is running iOS 12 or older, you are not subject to this security issue.

For everyone else, it’s advisable to turn off the iPhone’s Wi-Fi connection Auto-Join option. Go to Wi-Fi > Auto-Join Hotspot > Never in the Settings menu.

Avoid connecting to Wi-Fi networks with % signs in their names, as this was how the older version of the vulnerability materialized and might still be how some hackers operate.

It’s also a great idea to keep backups of your iPhone data on hand just in case. Also, reset your Network settings to prevent your iPhone from automatically connecting to recognized networks. Navigate to Settings > Reset > Reset> Reset Network Settings to reset your network settings. And only connect to networks you’re familiar with.

Other Measures

1. Updates should get installed as soon as feasible: Some updates get hastily implemented patches for freshly revealed security flaws. You may encounter annoyances such as delayed loading times or minor issues initially installing updates. On the other hand, these tiny inconveniences are better for someone to access your phone and take your identity.

2. Create a two-factor authentication system: Set up two-factor authentication to keep unwanted users from your Apple and iCloud accounts. Biometrics-based multifactor authentication is much better!

3. When using public Wi-Fi, use a VPN: Anyone with access to the same network is susceptible while using public Wi-Fi. When you use a VPN on your iPhone when connected to public Wi-Fi, you can safeguard your iPhone at a time when it gets most exposed to hackers.

4. Make a secure password: Make sure your password gets made up of a combination of letters, numbers, and special characters. It should be unique to your Apple ID and contain at least 12 characters for best password security.

5. Please don’t give out personal information without first verifying its integrity: Before submitting personally sensitive data, check the asking organization’s website to ensure it’s legitimate.

6. When you’re not using Bluetooth, please turn it off: Hackers can access your iPhone by discovering and spoofing other devices you’ve connected to previously. 

1. Head to Settings.

2. Select “Bluetooth.”

3. Click the Switch icon to turn it off.

4. Create a passcode: After you’ve completed these steps, putting your phone down for an extended length of time will require a passcode to unlock it.

Go to the Settings menu.

1. “Touch ID & Passcode” will appear.

2. Turn on the passcode by tapping “Turn Passcode On.”

3. Select “Passcode Options” from the drop-down menu.

4. “Create a Custom Alphanumeric/Numeric Code” is the option.

How Can You Tell If You’ve Been Hacked?

When a phone gets hacked, there are frequently specific obvious signals that anything is wrong:

1. The phone is always heated and has a low battery.

2. Regardless of the connection quality, the phone takes a long time to load web pages.

3. You don’t recall making specific phone calls or sending SMS.

4. Your contacts claim they’ve been receiving strange texts from you.

5. Before assuming you’ve been hacked, do your homework. A new iOS update is sometimes to blame. Alternatively, if your iPhone is more than two years old, its battery may be approaching scheduled obsolescence. 

NOTE: There isn’t a single example of what your iPhone looks like after it’s hacked. Strange or inappropriate pop-ups may appear, and you may see programs on your phone that you are unfamiliar with on your screen. The most obvious clue would be if your contacts received messages or phone calls from you that you did not initiate.

Conclusion

When it comes to the morality of hacking, it’s a touchy matter. However, even if the entire process is contaminated, there are times when it may be beneficial for their better benefit.

Furthermore, if you can hack one iPhone, you can hack any iPhone, which indicates that everyone is vulnerable to being hacked. This vulnerability is why Apple and other software developers place such a high priority on security.

Even though it may appear to be an impossible undertaking, breaking into an iPhone is doable. You can always hire a professional hacker to do the job for you.
