A newly discovered security vulnerability, dubbed CVE-2024-44207, has recently been identified and patched in Apple's iOS 18..1 and iPadOS 18..1. This security issue involved audio messages in the Messages app that could potentially allow attackers to capture a few seconds of audio before the microphone indicator was activated, effectively recording without the user's knowledge. Thankfully, Apple has promptly addressed this issue with improved checks to ensure the privacy and security of their users.

Exploit Details

The vulnerability lies in the way the Messages app handles audio recordings for audio messages. Due to insufficient checks, an attacker could potentially exploit this issue to capture a few seconds of audio discreetly without the user being aware that their microphone is active. This could lead to the leaking of sensitive information or personal conversations.

Here is a simplified code snippet that demonstrates the vulnerability

def start_recording():
    # Time delay allows the recording to start before the microphone indicator is shown
    time.sleep(2)
    show_microphone_indicator()
    record_audio()

def send_audio_message():
    start_recording()
    stop_recording()
    send_message()

As seen in the above code snippet, the start_recording function contains a time delay that enables recording to start before the microphone indicator is shown to the user. This could potentially be exploited to record sensitive audio without the user's knowledge.
