Why the iPhone's Messages App Refuses Audio Messages That Mention 'Dave & Buster's'

In a bizarre bug that has left many iPhone users scratching their heads, Apple's messaging app has been found to refuse sending audio messages that include the name "Dave and Buster's". The issue was first spotted by app developer Guilherme Rambo, who warned iPhone users earlier this month about the peculiar problem.

According to Rambo, the bug occurs when an iPhone user tries to send an audio message using the Messages app to someone else who is also using the Messages app. If the recipient happens to mention "Dave and Buster's" in their message, the audio message will never be received. Instead, the recipient will see a "dot dot dot" animation for several seconds before it disappears.

The reason behind this anomaly lies in the way Apple's BlastDoor feature protects users from malicious messages that might rely on faulty data parsing. When an iPhone user sends an audio message with incorrect formatting, specifically when including the ampersand (&) symbol in the name "Dave and Buster's", the transcription engine on iOS recognizes it as a problematic parsing error.

"The parsing error triggers Apple's BlastDoor Messages feature," explains Rambo. "So far, so good." However, what happens next is that the audio message fails to send due to the BlastDoor mechanism's strict formatting requirements. In this case, the ampersand (&) symbol has special meaning in HTML and XHTML, making it an invalid character for use in a brand name.

To get to the bottom of the mystery, Rambo plugged the recipient device into his Mac and captured the logs right after the device received the problematic message. The results showed that BlastDoor was indeed at work, protecting users from what could be seen as a potential security exploit.

"Since BlastDoor was designed to thwart hacking attempts, which frequently rely on faulty data parsing, it immediately stops what it's doing and just fails," says Rambo. "That's what causes the message to get stuck in the 'dot dot dot' state, which eventually times out, and the message just disappears."

While this bug may seem like a convenient way to send "hacked" messages to someone's iPhone via bad audio message transcription, it actually highlights the effectiveness of Apple's BlastDoor mechanism. By being pedantic about formatting, BlastDoor is protecting users from an exploit that would abuse data parsing issues.

As for what this means for regular iPhone users, don't worry – you can breathe a sigh of relief knowing that your messages are safe from malicious hackers. However, it's always good to be aware of the quirks and limitations of our devices, especially when it comes to security features like BlastDoor.

So there you have it – the curious case of why the iPhone's Messages App refuses audio messages that mention "Dave & Buster's". While it may seem like a minor issue, it's a great example of how Apple's security measures can sometimes lead to unexpected results.
