- The MAC address variable is an important one when it comes to tracking devices on your network. Most networks use DHCP servers so you cannot rely on tracking activity based on IP addresses only. MAC addresses are unique per device so they will give you a reliable audit trail as to what is happening on your network.

Your smartphone, your laptop, your computer, your tablet, even your smart watch all carry a unique identity, and we are not just talking about their looks. Every device has a string of characters unique to them that helps identify them, used to identify them in a network environment. While this is awesome to know for knowing what devices are on your network or are malfunctioning, it also could be used more nefariously. Welcome back to #TechTuesday, where we are going to explain MAC Addresses, and how they are used for tracking.

Every physical networked device, whether wired or wireless, is given to the consumer with a unique MAC address. Designed to be unique to that device, this identity allows networks to identify the device when it connects. This identity is actually very useful in home networking, allowing you to easily assign a static IP address based on the MAC of the device you would like to receive that identity. The network will be able to decide if you have connected previously, and recall settings specific to that device. Of course, you can change the MAC of a device in the software of it, but seldom is this technique used.
This seems like no major issue, right? Identifying yourself on a network is a courtesy, plus it only does so on networks you're connected to. Well, not quite. The concern arises with the mobile devices we use, such as our smartphones, tablets, and laptops because of how Wi-Fi works.
Scanning For Signals
When you leave your home, do you turn off your Wi-Fi chip on your smartphone? Do you entirely turn off your laptop or tablet to save battery? If not, chances are these devices are automatically scanning for available Wi-Fi networks as you move around. These devices, while enabled, use a passive discovery system that listens for Wi-Fi access points nearby that are broadcasting connections, and an active discovery that will broadcast requests for an access point. While doing this, because of how this system is designed, your device will broadcast its MAC address as a part of the discovery request. So as you're wandering around with that Wi-Fi chip enabled on your smartphone, it is broadcasting your presence to any network that will listen. https://elderever620.weebly.com/blog/mac-create-app-launcher. https://elderever620.weebly.com/blog/app-that-automatically-deletes-empty-folders-on-a-mac.
So you might wonder how this is used to track you? Well, I will take London for an example. Recently, they have Wi-Fi enabled garbage cans all across the city, set up by advertisers, that offer free connections. These cans have Wi-Fi monitoring hardware in them, and are all networked together for consistency. If you happen to pass one of these cans with your Wi-Fi enabled, your phone will ping the can with its MAC address, and the can would make note of the address and the location. As you move through the city, this process would repeat, giving a general idea of where you have been moving. This same thing can be done in stores, giving an idea where in a store you might have wandered based on the sniffers logging your mac address and current relative location. This information could be used to track you down based on a wide area, or sold to advertisers to advertise directly based on your habits and frequent visits of a location.
So how do you get around this all, though? Well, there's not a solid solution right now just yet. At least, not on all devices. Apple did fix this with their newest iOS 8, which will randomize your device's MAC address each time it scans for nearby networks, making the address worthless for tracking. While this is a solid step in the right direction, we have yet to see other developers pick this habit up just yet, but only because it was not much of a known issue until it became so. Of course, if someone really wanted to track you, there are a variety of ways such as cell signal and GPS location. But every step we can take to protect ourselves and our privacy is a step in the right direction.
- The popular TikTok app has been collecting personally identifiable user data, a new investigation shows.
- TikTok exploited a still-active loophole that allowed it to bypass Google’s privacy requirements for Android app developers.
- TikTok accessed MAC addresses on Android for at 15 months and used an additional layer of encryption to hide this collection of data.
- The TikTok user tracking feature was removed in November, at a time when Google was already aware that apps were exploiting the Android security loophole.
ByteDance and its popular app TikTok have faced intense scrutiny in the US lately, with the Trump administration accusing voicing security concerns about the app. The government shared its fears that the app could collect user data that could then be used by the Chinese government, and told ByteDance to sell its TikTok operations in America. Separately, Trump issued a new executive order that would prevent ByteDance from doing business in the States.

It turns out there is a cause of concern when it comes to user data. TikTok has been collecting sensitive data from Android users up until last November, taking advantage of an Android loophole that other apps use, skirting Google’s privacy rules for Android. It’s not just TikTok at fault for tracking users, as Google had not patched that exploit even though it knew about its existence.
Stock Tracker Mac
An investigation from The Wall Street Journal shows that TikTok was collecting the MAC addresses of Android devices, in violation of privacy safeguards that Google has in place for Android.
The MAC addresses are unique identifiers for every device that can connect to the Internet, smartphones included. MACs can be associated with other app data from the same phone and other sources to track users online. Apple stopped making MAC data available to apps in 2013, and Google followed two years later.
TikTok said earlier this year that its app collects personal data less than Facebook and Google. At the time, it wasn’t known the app was tracking users via MAC data. A company spokesperson told The Journal that “the current version of TikTok does not collect MAC addresses.” The harm may already be done, however.
TikTok used a workaround to bypass Google’s MAC collection restrictions in Android, the report notes, and then it hid its actions under a supplementary layer of encryption. TikTok’s internet traffic is already encrypted in transmission, which is a common practice for most internet traffic nowadays. However, TikTok added an extra layer of custom encryption that served no security purpose other than to hide the fact that MAC addresses were collected.
The way TikTok collected user data allowed for perpetual user-tracking:
TikTok bundled the MAC address with other device data and sent it to ByteDance when the app was first installed and opened on a new device. That bundle also included the device’s advertising ID, a 32-digit number intended to allow advertisers to track consumer behavior while giving the user some measure of anonymity and control over their information.
That advertising ID can be reset, but if someone has access to the MAC information, they could just pair the new advertising ID with the MAC address. The only way to get out of this would be changing phones and removing TikTok.
TikTok collected MAC data for 15 months before the feature was removed.
Google shares the blame here, considering The Journal’s findings. TikTok wasn’t the only app abusing the loophole. The security hole is widely known, Joel Reardon told the paper. Reardon is an assistant professor at the University of Calgary and the co-founder of AppCensus. The company looked at 25,152 popular Android apps in 2018 and found that 347 of them were accessing MAC addresses.
Reardon filed a formal bug report about the issue last June, as he discovered the latest version of Android did not fix the problem. https://elderever620.weebly.com/blog/mac-apps-to-paint-on-photos. “I was shocked that it was still exploitable,” he said, adding that Google told him it had a similar report on file at the time he filed his finding. Google confirmed to The Journal is investigating TikTok’s collection of MAC addresses but declined on commenting about the security loophole.
Microsoft, which has shown interest in purchasing the US portion of TikTop, also declined to comment on whether it knew about TikTok’s data collection.
On a different note, this whole security issue shows that if there’s any sort of loophole in an operating system, those who will find it can abuse it. Replace loophole with encryption backdoor, and you get the same result, albeit with a lot more serious consequences.
