Does NSA Know Your Wi-Fi Password? Android Backups May Give It to Them
On by default on most newer Android devices, Google’s Android backup stores your personal details in plaintext.
If you’re using Google’s “back up my data” feature for Android, the passwords to the Wi-Fi networks you access from your smartphone or tablet are available in plaintext to anyone with access to the data. And as a bug report submitted by an employee of the Electronic Frontier Foundation (EFF) on July 12 suggests, that leaves them wide open to harvesting by agencies like the NSA or the FBI.
