That App Has a Back Door to Your Digital Life

Ever wonder why that flashlight app needed access to your contacts? Or why a game asked to read your call logs? You’re not paranoid—you’re just starting to see the frightening reality of third-party app permissions. I recently dove deep into third-party app permissions while researching my upcoming book about personal cybersecurity, and what I discovered about app permissions will make you rethink every ‘Accept’ button you’ve ever clicked.
The Hidden Price of Convenience
One topic keeps coming up repeatedly in data breach reports: third-party apps. According to recent studies, 98% of organizations have third-party vendors who have suffered data breaches, and 61% of companies experienced third-party data breaches over the past year—a 49% increase from 2023.
The Average Android App Requests 11 Permissions
The average popular Android app requests 11 dangerous permissions, with communication apps averaging nearly 19 permissions and social apps requesting 17.2 dangerous permissions. These aren’t just numbers—they represent potential entry points for cybercriminals.
A recent report found that 74% of organizations that experienced data breaches said they were breached because they gave too many access privileges to a third-party app. Even more alarming, 15% of all data breaches in 2024 involved supply chain compromises, including third-party software vulnerabilities—up from just 4% in 2020.
The Most Dangerous Permissions You’re Probably Granting
Through my research, I’ve identified the permissions that pose the greatest risk:
Location Access: Your location data reveals far more than just where you are—it exposes your home address, where your kids go to school, your daily habits, and even your route patterns. All this information can be sold to third parties, used for identity theft, or exploited to plan physical crimes.
Camera and Microphone Access: With full access to your camera and microphone, malicious apps could theoretically spy on you, capture sensitive information, or record audio and video without your consent. Some apps even use microphone access for advertising purposes, listening to what TV shows you watch to build advertising profiles.
Contact Access: Granting contact access allows apps to harvest not just your information, but your friends’ and family’s data too. Cybercriminals can use this for targeted phishing scams, making fraudulent messages appear to come from people you trust.
File Storage Access: When apps request access to read or modify external storage, they can potentially access sensitive files like photos of your ID, financial documents, or personal photos. About 77% of apps request permission to read external storage.
Third-Party Breach Examples
The impact isn’t theoretical. In 2024, major companies like AT&T faced breaches affecting 70 million customers, while Ticketmaster suffered a breach impacting 560 million users. In both cases, vulnerabilities in third-party systems were exploited, leading to massive data exposure.
Even more concerning, research shows that almost all analyzed popular apps (94%) ask for notification permissions, which can be exploited to bombard users with ads, phishing links, or misinformation. Notifications have even been previously exploited by commercial spyware vendors for tracking users.
Actions to Take Now
Here’s what I recommend based on my research:
- Audit Your Current Apps: Go through your phone settings and review the permissions you’ve granted. Ask yourself: Does this flashlight app really need access to my contacts? Does this game need my location? Many permissions can be revoked without affecting the app’s core functionality.
- Change Default Settings: When installing new apps, don’t just click ‘Accept All.’ Instead, selectively grant permissions. For location access, choose ‘Only while using the app’ instead of ‘Always.’ For many apps, you can deny risky permissions entirely without losing functionality.
Don’t Automatically Grant Access
As I continue writing my book on personal cybersecurity, one thing becomes clearer: the biggest threats often come from the devices in our pockets. Every permission you grant is a potential gateway for cybercriminals. The good news? You have more control than you think.
Start small—check one app’s permissions today. You might be shocked at what you’ve been allowing.
