- Outdated systems are considered the weakest link in device security.
- The rollout is gradual and affects users globally, including in Israel.
WhatsApp is implementing a new security measure that will prevent users from accessing their accounts on devices running outdated versions of Android and iOS. The change, rolled out server-side by Meta, aims to protect user data by ensuring that the underlying phone operating system is secure before end-to-end encryption can be effective.
Users attempting to log in on a device with an outdated operating system will be met with a mandatory alert screen, with no option to bypass it. They will be required to update their phone's operating system to proceed. Meta stated that this strict measure is not due to a flaw within WhatsApp itself, but rather a recognition that end-to-end encryption is ineffective if the phone's basic infrastructure is compromised.
Cybercriminals can exploit known vulnerabilities in older operating systems to install malware and spyware on devices. Once a phone is infected, attackers can intercept texts, images, and recordings directly from the device's memory or keyboard before WhatsApp can encrypt and transmit the information.
This new requirement joins other recent security initiatives by WhatsApp, including warnings against unofficial web plugins, AI-based scam detection, and the replacement of two-factor authentication codes with complex passwords. Security experts emphasize that an operating system that has not been updated for months or years represents the weakest link in the chain, exposing all applications on the phone to surveillance and identity theft.
The blocking mechanism is being gradually distributed to accounts worldwide, including in Israel. WhatsApp has not provided a specific list of operating system versions deemed unsafe. To avoid being disconnected, users are advised to check their smartphone's settings under "Software Updates" and ensure they have the latest version provided by their device manufacturer.
