[ACBS] Update your phone’s security to protect your securities account

Apple and Google have recently released security updates to fix vulnerabilities in iOS and Android. If a device is not updated, attackers may exploit it to break in, steal personal information, and put investors’ securities accounts and transactions at risk.

ACBS therefore recommends that you check and update your phone as soon as possible, following the instructions below:

1. For iPhone or iPad

Apple released a security patch on October 26, 2026. Please update to the version below (or later), depending on the operating system you use:

• iOS/iPadOS 27: version 27.2
• iOS/iPadOS 26: version 26.7.2 (for supported devices)
• iOS/iPadOS 18: version 18.7.11 (for supported devices)

🔃 How to update: Settings → General → Software Update.

2. For Android phones or tablets

Google has published its October 2026 security patch, which includes two patch levels: October 1, 2026 and October 5, 2026. Please update to the latest version available, at patch level October 5, 2026 or later.

3. Tips to protect your securities account

In addition to updating your device’s security, please note the following:

• Do not share your username, password, OTP, or any other security information with anyone.
• Do not click on unfamiliar links or install apps from unknown sources.
• Decline any request to install an app, share your screen, or remotely control your device from strangers.
• Regularly check your account balance, transaction history, and account status.
