**WhatsApp Fixes iOS, Mac 'Zero Click' Bug Used In Targeted Attacks On Apple Devices**

A critical security vulnerability has been patched in the WhatsApp messaging app on both iOS and Mac devices, which was exploited by hackers to target specific users in a stealthy manner. The bug, tracked as CVE-2025-5517, allowed attackers to gain unauthorized access to the device without any user interaction.

**The Attack: A "Zero-Click" Hack**

According to Donncha Ó Cearbhaill, head of Amnesty International's Security Lab, the attack was an "advanced spyware campaign" that utilized a zero-click exploit. This means that the attackers could compromise the device without requiring any user interaction or consent. The bug has been in place since late May and was used to target WhatsApp users for the past three months.

**A Sophisticated Attack**

Apple described the attack as "extremely sophisticated," indicating that it required a high level of technical expertise to execute. The attackers were able to use this vulnerability in conjunction with another Apple flaw, labeled as CVE-2025-43300, to send a malicious exploit via WhatsApp and access sensitive data from Apple devices.

**Affected Users: What You Need To Know**

WhatsApp has notified dozens of users who may have been affected by the bug. If you receive an alert indicating that your WhatsApp account may be vulnerable to this attack, it's essential to take immediate action. The company has confirmed that the issue has been fixed, but it's crucial to update your app as soon as possible.

**A Growing Concern**

This incident is not the first time WhatsApp has encountered a security vulnerability. In May, a US court ordered NSO Group to pay WhatsApp $167 million for hacking over 1,400 users' devices in a 2019 campaign. Earlier this year, WhatsApp blocked a spyware attack targeting about 90 users in Italy, including journalists and civil society members.

**What Can You Do?**

To protect yourself from this vulnerability:

* Ensure that your WhatsApp app is up to date. * Monitor your account activity closely for any suspicious behavior. * Be cautious when interacting with links or attachments from unknown sources. * Keep your device's operating system and security software up to date.

**Stay Safe Online**

As technology continues to evolve, it's essential to stay vigilant and take proactive measures to protect yourself from cyber threats. By staying informed and taking the necessary precautions, you can help prevent such attacks in the future.
