Apple’s AirPlay aims to simplify the experience of streaming music, photos, and videos from devices like iPhones and MacBooks to televisions and speakers. Yet, recent research highlights that this ease of use could be exploited by hackers. A set of vulnerabilities termed “Airborne” allows AirPlay-compatible devices to become hidden entry points for malware and unauthorized network access.
Researchers at Oligo, a cybersecurity firm based in Tel Aviv, recently disclosed these weaknesses in Apple’s proprietary AirPlay protocols. These security flaws primarily exist within the AirPlay Software Development Kits (SDKs) used by third-party manufacturers for smart TVs and other devices. Specifically, if an attacker shares the same Wi-Fi network as a vulnerable device, they can hijack it without physical access.
This would enable the hacker to navigate within a home or business network, potentially installing malware or ransomware, disrupting operations, or locking users out of their systems. Additionally, compromised devices can be co-opted into a botnet, which can be used for larger attacks. Many smart devices, equipped with microphones, could also be turned into surveillance tools.
Apple has taken steps to address these vulnerabilities by patching its own devices and updating third-party vendors. However, numerous third-party AirPlay-enabled products—likely tens of millions—remain unprotected. Some may not receive automatic updates, and other vendors may lack the initiative to issue security patches.
A demonstration by Oligo illustrated how easily a speaker could be commandeered to display unauthorized content. While a specific manufacturer was not targeted, the incident underscores a broader risk: any device using the AirPlay SDK can be a potential gateway for malicious actors.
Furthermore, researchers found that Apple Carplay is also susceptible to these vulnerabilities. Although exploitation here is trickier and involves Bluetooth or USB connections, over 800 vehicle models could be at risk.
For those looking to safeguard their devices, here are some essential steps:
- Create a separate Wi-Fi network: Most routers allow multiple networks. Keep smart devices like AirPlay-enabled speakers on a different “IoT” network from your important devices to minimize risk.
- Disable AirPlay when not in use: Turn off AirPlay in device settings to avoid cross-device vulnerabilities.
- Avoid public Wi-Fi: Connecting to unsecured networks increases the risk of exploitation. If necessary, do not engage in streaming while connected to these networks.
- Secure your home Wi-Fi: Use a strong, unique password, keep router firmware updated, and avoid outdated settings like WEP.
- Limit device permissions: Turn off unnecessary features such as microphones or remote access, reducing exposure for potential hacks.
While Apple markets itself as a leader in privacy and security, these Airborne vulnerabilities demonstrate that its devices may not be as secure as advertised. The need for a more robust approach to third-party AirPlay devices is clear, as vulnerabilities persist long after patches are applied. The company must take more proactive measures if it seeks to be genuinely regarded as a privacy champion.
