Facebook And Dropbox Are Seriously Vulnerable To Hackers Right Now:

world-shaker:

A motivated hacker could copy a plain text file off of your mobile device that would grant him access to your entire account.

The problem exists within the app itself — the sensitive data isn’t encrypted, it simply sits on your device in plain, readable form.

There’s no jailbreak required to get this data either. Using a free piece of software called iExplore, which lets you browse your iPhone as if it were an external hard drive, Wright was able to gain access to the text file.

Looks like it affects the iOS and Android apps.
