A technical report has warned of a security flaw in recent iPhone models that could expose hundreds of millions of users to hacking risks, due to a default setting that allows USB accessories to connect automatically once the phone is unlocked. Despite multiple updates released by Apple, the issue remains unresolved.
Details
Concerns have grown alongside reports of spyware exploiting direct wired connections to access user data, especially through public charging ports.
- The current iOS setting enables automatic connections when the device is unlocked
- This allows data connections to be established when plugging into untrusted cables
- A safer option would require user permission before each new connection
Apple provides several options to manage USB connections, including:
- Always Ask
- Ask for New Accessories
- Automatically Allow When Unlocked
- Always Allow
However, setting the third option as default raises concerns, as it reduces security in high-risk environments such as hotels and airports.
Experts advise switching the setting to Always Ask or Ask for New Accessories via:
Settings → Privacy & Security → Wired Accessories
What’s Next?
Attention is now on upcoming iOS updates to see whether Apple will change the default setting, as warnings about potential exploitation continue.
