Don't trust this one security app

The NQ Mobile Vault security app received rave reviews in the past, but now it has been exposed as a fraud. It turns out the app is using weak encryption and leaving your data exposed, and it might not be alone. Is this app an outlier or are there more security pretenders out there leaving your information at risk?

NQ Mobile Vault claims to use encryption to provide "maximum privacy" for pictures, videos, texts, Facebook messages and other data on your phone. It has rating of 4.4 on the Google Play store and over 30 million users. There's only one problem. It's not actually that secure.

The app uses a form of encryption called 8-bit XOR that, on its own, is easy to crack. Just take a look at it compared to the much stronger AES-256 encryption that is used for SSL, online banking transactions, Wi-Fi and many other purposes.

Let’s compare the number of possible keys for AES-256 with NQ Vault’s XOR-8:

AES-256: 11,580,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,
000,000,000,000,000,000

NQ Vault: 255
