Apple users have been issued a "High Severity" warning by the Indian Computer Emergency Response Team, or CERT-In, cautioning that multiple critical vulnerabilities can indeed allow hackers to take full control of iPhones, iPads, and Macs. According to the advisory of November 10, 2025 (CIAD-2025-0041), these Apple bugs might expose your personal data, including photos, chats, and financial information, and may even allow the attacker to lock the device completely. CERT-In has asked users to take immediate action by updating their software to prevent potential exploitation. But with Apple devices now being commonly used across India by professionals, students, and businesses alike for sensitive activities, including UPI payments, online banking, and access to government apps like DigiLocker and Aadhaar, the advisory is a timely reminder that keeping security updated is of the essence to protect personal and financial information.

CIAD-2025-0041 the advisory from CERT-In explains that the vulnerabilities found in Apple's operating systems could let attackers execute arbitrary code, a technical term meaning a hacker could secretly install and run harmful software on your device. This could give them the power to access, modify, or delete your data without your knowledge.

Even more concerning, the flaws could allow for privilege escalation, meaning hackers could gain admin-level access to your system, similar to having the master key to your digital home. Other potential issues include bypassing security restrictions, stealing sensitive data, and even triggering denial-of-service (DoS) attacks, which could render your device unusable.

For the average Indian user, that could mean everything from losing access to banking apps to seeing your iPhone freeze or restart repeatedly. The danger also extends to professionals using Macs for business or design work; an unpatched vulnerability could lead to stolen projects or leaked client data.

The list of affected Apple devices is quite long and includes almost all of the company's products. CERT-In says users are at risk if they are using any of these versions:

If you haven't updated your Apple device recently, particularly if you're still running older software versions, your device is likely exposed. Many Indian users tend to skip or delay updates because of internet data costs, limited Wi-Fi, or fear of slowing down older devices. However, this time, skipping an update could mean opening the door to hackers.
