Security experts are urging billions of iPhone users to disable three default settings that could leave their personal data exposed to cybercriminals. These settings, which are automatically enabled on all Apple devices, could make users vulnerable to hacking attempts, identity theft, and financial fraud.
Cybercriminals are constantly finding new ways to steal sensitive data, including Social Security numbers, credit card details, passwords, and even home addresses. If hackers gain access to this information, they can drain bank accounts, steal identities, or sell personal data for profit. To protect yourself, it’s crucial to turn off these three high-risk settings immediately.
1. Wi-Fi and Bluetooth Auto-Connect
While having Wi-Fi and Bluetooth enabled at all times might seem convenient, it can also be a security risk. When your iPhone constantly searches for available networks, it may automatically connect to an unsecured or malicious hotspot controlled by a hacker. This is especially common in public places like coffee shops, restaurants, and airports.
Hackers use a technique known as an “evil twin” attack, where they create fake Wi-Fi networks that appear legitimate. Once your device connects to the rogue hotspot, cybercriminals can intercept your data, install malware, and track your online activities.
According to the National Security Agency (NSA), it’s best to disable automatic Wi-Fi connections by turning off the “Auto-Join Hotspot” feature. The agency also warns against connecting to public Wi-Fi networks that do not require a password, as they are more vulnerable to hacking attempts.

Bluetooth connections pose a similar risk. Leaving Bluetooth turned on allows attackers to exploit vulnerabilities in your device through a technique called a “BlueBorne” attack. This type of cyberattack enables hackers to gain unauthorized access to your phone without you realizing it.
How to Disable Auto-Connect:
- Wi-Fi: Go to Settings > Wi-Fi > Turn off Auto-Join Hotspot.
- Bluetooth: Go to Settings > Bluetooth > Toggle Bluetooth off when not in use.
2. Location Services
Another setting that could be putting your personal data at risk is Location Services. Many apps request access to your location, but granting them unlimited tracking permissions could expose you to privacy risks. Hackers who gain access to apps with location tracking can monitor your movements and obtain detailed information about your daily routines.
Earlier this year, cybercriminals exploited a vulnerability in Gravy Analytics, an app that collects user location data for marketing purposes. Hackers managed to steal vast amounts of personal information, including real-time location tracking of users.
To prevent such risks, security experts recommend restricting location access for apps that don’t require it and adjusting settings to only allow tracking when the app is in use.
How to Adjust Location Settings:
- Go to Settings > Privacy & Security > Location Services.
- Review the apps listed and adjust their settings to While Using the App or Never.
- For apps like Maps and Weather, select “While Using the App” instead of “Always” to limit tracking.
3. App Tracking Transparency (ATT)
Have you ever felt like your iPhone was “listening” to your conversations? If you’ve mentioned a product in conversation and then suddenly seen ads for it, you’re not imagining things. Your phone collects vast amounts of data about you, and some apps share that data without your knowledge.
Apple introduced App Tracking Transparency (ATT) to give users more control over how their data is collected. However, this feature is often overlooked or disabled by default, leaving users vulnerable to aggressive data tracking.
Apps use tracking technology to monitor your browsing habits, device usage, and even personal identifiers like your email and phone number. This data is then used to build digital profiles for targeted advertising, which can be exploited if it falls into the wrong hands.
How to Enable App Tracking Transparency:
- Go to Settings > Privacy & Security > Tracking.
- Toggle off “Allow Apps to Request to Track” to prevent apps from collecting data without permission.
- Review existing apps that have tracking enabled and disable them if necessary.
Additional Security Measures for iPhone Users
Beyond these three settings, the National Security Agency (NSA) also recommends rebooting your phone at least once a week. Restarting your device can disrupt malware and spyware from taking hold, forcing attackers to restart their hacking attempts from scratch.
Neal Ziring, the NSA’s Technical Director for the Capabilities Directorate, explains that many modern cyberattacks require a sequence of vulnerabilities to be exploited. Restarting your device regularly “resets the adversary back to the beginning” of their attack chain, making it harder for hackers to gain persistent access to your phone.
The NSA also advises users to:
- Keep Wi-Fi, Bluetooth, and cellular data turned off when not in use.
- Avoid using public Wi-Fi, especially in airports and hotels.
- Use a secure VPN when accessing sensitive information online.
- Keep iOS software and apps up to date.
- Enable two-factor authentication for added security.
Final Thoughts
Cybercriminals are constantly evolving their tactics, making it more important than ever to safeguard your personal data. By disabling Wi-Fi Auto-Join, restricting Location Services, and turning on App Tracking Transparency, iPhone users can significantly reduce their risk of being hacked.
With billions of iPhone users worldwide, taking these simple precautions can help protect against identity theft, financial fraud, and data breaches. Follow these expert security tips today to keep your personal information safe from cyber threats.
