What happened

Apple started showing Critical Software lock-screen alerts to people using older iOS and iPadOS versions, warning that attackers are actively targeting out-of-date devices via malicious web content. Apple’s guidance is clear: install the latest available security update for your device as soon as possible.

This follows Apple’s recent security messaging about exploit activity affecting older software branches and expanded patch coverage for older hardware that cannot run the newest iOS generation.

Why this matters

If your iPhone or iPad is behind on updates, a single malicious link or compromised website can create real risk for personal data, accounts, and device integrity.

Even if these campaigns often start as targeted operations, once exploit details spread, copycat abuse can grow quickly. The practical takeaway for everyday users is simple: being even a few updates behind increases exposure.

How to check if you’re affected

Affected devices/versions: any iPhone or iPad running an older (not-latest) security patch level for its supported iOS/iPadOS branch.

Check your current version
- Go to Settings → General → About → iOS Version (or iPadOS version).
Install updates immediately
- Go to Settings → General → Software Update and install the latest update offered for your device.
Confirm you are on a supported, patched branch
- Compare your installed version with Apple’s security release records.
If your device cannot update to the newest major iOS, install the latest available patch for your branch
- Apple has released security updates for older supported devices as well.
If you are high-risk or can’t update immediately, enable Lockdown Mode
- Use this as a temporary hardening step while you complete patching.

What to do right now

Update iOS/iPadOS today (don’t postpone).
Keep automatic updates enabled.
Be extra cautious with links received by SMS, email, or social apps until patched.

Bottom line

If you or family members are running older iOS/iPadOS versions, this is a high-priority maintenance task. Verify versions, patch immediately, and use Lockdown Mode where appropriate until fully updated.
