Google knows nearly every Wi-Fi password in the world
If an Android device (phone or tablet) has ever logged on to a particular Wi-Fi network, then Google probably knows the Wi-Fi password. Considering how many Android devices there are, it is likely that Google can access most Wi-Fi passwords worldwide.
Recently IDC reported that 187 million Android phones were shipped in the second quarter of this year. That multiplies out to 748 million phones in 2013, a figure that does not include Android tablets.
Many (probably most) of these Android phones and tablets are phoning home to Google, backing up Wi-Fi passwords along with other assorted settings. And, although they have never said so directly, it is obvious that Google can read the passwords.
Sounds like a James Bond movie.
Android devices have defaulted to coughing up Wi-Fi passwords since version 2.2. And, since the feature is presented as a good thing, most people wouldn't change it. I suspect that many Android users have never even seen the configuration option controlling this. After all, there are dozens and dozens of system settings to configure.
What is not said, is that Google can read the Wi-Fi passwords.
And, if you are reading this and thinking about one Wi-Fi network, be aware that Android devices remember the passwords to every Wi-Fi network they have logged on to. The Register writes
The list of Wi-Fi networks and passwords stored on a device is likely to extend far beyond a user's home, and include hotels, shops, libraries, friends' houses, offices and all manner of other places. Adding this information to the extensive maps of Wi-Fi access points built up over years by Google and others, and suddenly fandroids face a greater risk to their privacy if this data is scrutinised by outside agents.
The good news is that Android owners can opt out just by turning off the checkbox.
The bad news is that, like any American company, Google can be compelled by agencies of the U.S. government to silently spill the beans.
When it comes to Wi-Fi, the NSA, CIA and FBI may not need hackers and cryptographers. They may not need to exploit WPS or UPnP. If Android devices are offering up your secrets, WPA2 encryption and a long random password offer no protection.
I doubt that Google wants to rat out their own customers. They may simply have no choice. What large public American company would? Just yesterday, Marissa Mayer, the CEO of Yahoo, said executives faced jail if they revealed government secrets. Lavabit felt there was a choice, but it was a single person operation.
This is not to pick on Google exclusively. After all, Dropbox can read the files you store with them. So too, can Microsoft read files stored in SkyDrive. And, although the Washington Post reported back in April that Apple’s iMessage encryption foils law enforcement, cryptographer Matthew Green did a simple experiment that showed that Apple can read your iMessages.
