WhatsApp Emergency Security Update: Protect Your Device Today
What Happened
The flaw (CVE-2025-55177) exploited the way WhatsApp synced messages across linked devices.
Attackers combined this with a separate Apple operating system vulnerability (CVE-2025-43300) to deliver spyware silently.
The attack campaign lasted around 90 days and was highly targeted, aimed at fewer than 200 users worldwide, including journalists and civil society members.
Why This Matters
Zero-click exploits are rare, but they’re extremely serious because they don’t rely on human error. Simply having WhatsApp installed on your phone or computer could have been enough to make you a target. While Meta (WhatsApp’s parent company) moved quickly to release a fix, users must take action to close the vulnerability.
What You Should Do
Update WhatsApp immediately:
iOS users should install version 2.25.21.73 (or newer).
WhatsApp Business on iOS and WhatsApp for Mac should be updated to 2.25.21.78 (or newer).
Update your operating system: Ensure your iPhone, iPad, and Mac are running the latest version of Apple’s software.
Check for notifications: WhatsApp directly notified affected users. If you received an alert, follow the instructions, which may include performing a factory reset.
Enable extra security:
On iPhone, turn on Lockdown Mode if you may be at higher risk.
On Android, enable Advanced Protection Mode.
The Bottom Line
Even trusted platforms like WhatsApp can become targets for advanced cyberattacks. The best defense is staying proactive—update your apps and devices as soon as patches are released and consider enabling advanced protections if you work in sensitive fields.
