A 0-day bug, also known as a zero-day vulnerability, is a type of software flaw that is unknown to the software vendor. This means that the developers of the software are unaware of the issue, leaving it open to exploitation by malicious actors. In the case of WhatsApp, the 0-day bug allows attackers to remotely install spyware on a user's device without their knowledge or consent.

How does the WhatsApp 0-day bug work?
The WhatsApp 0-day bug exploits a buffer overflow whatsapp number database vulnerability in the app's VoIP stack. This allows attackers to send a specially crafted malicious code via a call to the target device. Once the code is executed, the attacker gains access to the device and can install spyware to gather sensitive information such as messages, call logs, and even access the device's camera and microphone.

The implications of the WhatsApp 0-day bug are severe, as it can compromise the privacy and security of millions of users worldwide. With the ability to remotely install spyware, attackers can eavesdrop on conversations, steal personal data, and potentially even track the physical location of a user. This poses a significant risk to both individuals and organizations that rely on WhatsApp for secure communication.
