Researchers: 2/3rds of Android apps suspiciously collect sensitive data without user consent

“Researchers from Intel Labs, Duke University, and Pennsylvania State University have created a tool that analyzes how Android apps handle the data they access on smartphones,” Elinor Mills reports for CNET. “Results from experiments on 30 apps might surprise some people.”

“When a user wants to download an Android app, a permissions screen is displayed that explains exactly what data and resources the app has access to, and users must click ‘OK’ before the download can proceed,” Mills reports. “The report suggests that users can be at risk because they are not told how the apps use their data. ‘Android’s course-grained access control provides insufficient protection against third-party applications seeking to collect sensitive data,’ the report, entitled ‘Realtime Privacy Monitoring on Smartphones,’ said.”

Mills reports, “Specifically, the researchers found that two-thirds of the 30 apps in the sample used sensitive data suspiciously, half share location data with advertising or analytics servers without requiring ‘implicit or explicit user consent,’ and one-third expose the device ID, sometimes with the phone number and the SIM card serial number. In all, the researchers said they found 68 instances of potential misuse of users’ private information across 20 applications.”

  1. HeadCheese,
    Click to flash is just a proxy that gates the execution (and display) of lfash content, it still appears to the website (in the case youtube) they you are a flash enabled user.
    Those who connect via a non flash device (like an iPad) are fed a h.264 stream.
    Many sites are doing this now (adaptive content) because of the huge number of non flash devices are too big a segment of the market to ignore. (or they ignore them at their own peril)

  3. Just to agree with Big Blue above, 30 apps is highly unlikely to be an appropriate sample size for the android market. The article does state that this was mostly to test out their new tool, but still they don’t need to add to sensationalist headlines when the average person has the statistical skills of a monkey.

  5. And how is this much different that Apple’s Safari or Apps?

    If your not private surfing with Firefox, and the add-ons of BetterPrivacy, Ad Block Plus, Ghostery, NoScript, TrackMeNot and WOT, your taking your chances.

    If you entered your personal info upon a new OS X install it’s giving out your personal info to everyone.

    If you don’t reboot your Mac after visiting sites you rather not anyone know about (besides your ISP) a simple terminal command can recover those sites visited, no root needed.

    If you don’t install a OS X outgoing firewall, any website can make your browser make unauthorized unseen connections. This happens a lot on the iPad and likely any iOS device as Apple will not allow certain software on their App Store.

  7. Ho hum. More of the same:

    “… the researchers said they found 68 instances of potential misuse of users’ private information across 20 applications.”

    It’s called ANDROID HELL.

    I get to sit back and watch while the Google Trolls rant and rave that Android Hell isn’t real. Have fun with that kids. I’m just gonna laugh while I play with my far safer iDevices.
