Imagine you're immersed in a virtual reality game, building a digital empire, when suddenly a hacker breaks into your world and steals your virtual treasures . Now, translate that scenario into real life: your iPhone or iPad, full of photos, messages, and banking details, could be the next target. This isn't science fiction: Apple has just released a critical patch for iOS 18.3.1 and iPadOS 18.3.1, fixing a vulnerability that allowed physical attackers to access locked devices. In this article, we explain why this patch is vital and how to protect your information in a world where even the most secure gadgets have vulnerabilities.
What is USB Restricted Mode and Why Does It Matter?
USB Restricted Mode is like a digital gatekeeper: if you leave your iPhone on a table for more than an hour, it blocks cable access unless you enter your passcode. Implemented in 2018, it was created to prevent tools like GrayKey (used by the FBI) from extracting data from locked devices.
How did the vulnerability (CVE-2025-24200) work?
- An attacker with physical access could disable this mode , even if the device was locked.
- This allowed malware to be installed or sensitive files to be copied without the password.
Real-life example: In 2023, security agencies used similar methods to access the phones of Spanish politicians infected with the Pegasus spyware.
Who Was Affected by This Risk?
Apple confirmed that the vulnerability was exploited in attacks targeting specific individuals , likely journalists, activists, or public figures. However, any user in Chile with these devices could be at risk:
Vulnerable devices:
- iPhone: XS, XR, 11, 12, 13, 14, 15, 16 and SE (2nd/3rd gen).
- iPad: Pro 11'' (1st gen+), Pro 12.9'' (3rd gen+), Air (3rd gen+), mini (5th gen+).
Why should you care?
- Chile is a growing target: According to OSIPTEL, cyberattacks increased by 62% in 2024, with an emphasis on the theft of personal data.
- The "domino effect": A hacked iPhone could expose home or corporate Wi-Fi networks.
Step by Step: How to Update Your Device
Protecting yourself is easier than installing an app. Follow these steps:
1. Connect to Wi-Fi: Avoid using mobile data (the update is ~500 MB).
2. Open Settings > General > Software Update.
3. Download iOS 18.3.1 or iPadOS 18.3.1 (or iPadOS 17.7.5 for older models).
4. Restart your device and check the version in *Settings > General > About*.
Bonus tip: Enable two-factor authentication for iCloud. This way, even if someone gains access to your device, they won't be able to access your account without an additional code.
Security Lessons: Beyond the Patch
This incident reveals three uncomfortable truths about cybersecurity in 2025:
1. Physical attacks are still prevalent: It's not enough to simply avoid suspicious connections; leaving your iPhone in a cafe can be risky.
2. Updates are your best shield: 40% of Chileans postpone updates, according to the INE.
3. Apple isn't invincible: In 2024, it fixed six zero-day vulnerabilities; in 2025, it already has two.
Case study: In 2024, an executive in Santiago was the victim of data theft using a modified USB cable. His unpatched iPhone 14 Pro allowed access to his corporate emails.
Frequently Asked Questions (FAQ)
Should I be concerned if my device isn't on the affected list?
No. Models prior to the iPhone XS (such as the iPhone 8) are not supported by iOS 18, but Apple released iPadOS 17.7.5 for older iPads.
How do I know if I've been hacked?
- Warning signs: Overheating, unknown apps, or error messages when connecting the cable.
- Solution: Restore the device from a clean backup and change all your passwords.
What happens if I don't update?
Your device will still work, but it will be vulnerable to attacks that could steal photos, WhatsApp messages, or even Apple Pay data.
Your iPhone is More than a Phone, Protect It
Cybersecurity isn't just for experts: it's a habit. This Apple patch is a reminder that even the most advanced devices require maintenance. In Chile, where 78% of the population uses an iPhone , updating today could prevent a data breach tomorrow.
