• Immediate action: update Apple devices to the latest iOS/iPadOS/macOS patch.

• Vulnerability CVE-2025-43300 enabled attackers to run malicious code through crafted images.

• CISA confirmed active exploitation; risks were focused but targeted assets include ETH and BTC in mobile wallets.

Apple zero-day vulnerability CVE-2025-43300 threatens crypto wallets—update iOS/iPadOS/macOS now to secure ETH, BTC and mobile assets. Update instructions inside.

What is the Apple zero-day vulnerability CVE-2025-43300?

CVE-2025-43300 is a zero-day flaw in Apple’s image processing components that allowed remote code execution when a device processed a crafted image file. The vulnerability affected iOS, iPadOS and macOS and posed a specific risk to mobile crypto wallets by exposing sensitive data to attackers.

How does CVE-2025-43300 threaten crypto wallets?

The exploit chain used crafted image files to trigger remote execution, giving attackers potential access to clipboard contents, transaction data and wallet session tokens on compromised devices. Mobile hot wallets for ETH and BTC are particularly exposed because they often run on devices that process images and receive external media.

Government and industry monitors, including CISA (as plain text reference), confirmed active exploitation and added CVE-2025-43300 to tracked vulnerability catalogs, underscoring the real-world targeting of mobile crypto users.

How can users secure their Apple devices and mobile wallets?

Follow these steps immediately to minimize risk:

1. Back up your device using encrypted backups.
2. Install the latest iOS, iPadOS or macOS security update from Settings → General → Software Update.
3. Restart your device after updating to ensure patches are applied.
4. Review wallet app permissions and revoke clipboard or file-access permissions where possible.
5. Consider moving significant holdings to cold storage until device integrity is confirmed.

Frequently Asked Questions

Do I need to update iOS, iPadOS and macOS now?

Yes. Installing Apple’s security update immediately closes the exploit vector used by CVE-2025-43300 and reduces the risk to mobile wallets and other sensitive apps. Patching is the primary defense against remote code execution via crafted images.

How can I tell if my wallet was compromised?

Indicators include unauthorized transactions, unknown approvals in wallet transaction history, unexpected clipboard activity, or unfamiliar app behavior. If you observe anomalies, move funds from hot wallets and rotate keys where feasible.

Key Takeaways

• Update now: Install Apple’s patch for CVE-2025-43300 on iOS, iPadOS and macOS immediately.
• Risk focus: The vulnerability enabled remote code execution via images and threatened ETH, BTC and hot-wallet data.
• Defensive steps: Back up devices, patch, restart, restrict wallet permissions, and consider cold storage for large holdings.

Conclusion

Apple’s swift patch for the Apple zero-day vulnerability CVE-2025-43300 mitigates a targeted threat to mobile crypto wallets, but users must act now.
