Just think of all those fun little Facebook apps you signed up for, tried once and then forgot about. They’re all still sat there, with access to your account and personal details. If one of the app developers wanted to, they could cause you a whole world of pain.
So. Much. Tech.
Some of the biggest names in tech are coming to TNW Conference in Amsterdam this May.
Even if you’re quite careful with the apps you install, check your Facebook and Twitter settings and you may be surprised just how many apps you’ve granted ‘additional permissions’ to.
I was slightly shocked to discover an amazing 66 apps had varying levels of access to my account. While most of these long-forgotten novelties couldn’t do much hard with simply the ability post my recent activity with the app to my wall, some had the ability to send me emails and – more frighteningly – access my data even when I wasn’t using the app.
In most cases the developers won’t mean any harm by this but it’s easy to see how some of them could cause trouble By leaving these unused apps with a backdoor to your data you’re leaving yourself open to potential trouble.
With Twitter, 13 apps have read and write access to my account. Most of these are third party Twitter clients like Brizzly and Seesmic but some (Twazzup, for example) I’d forgotten even existed and I may well never use again. As with Facebook, by leaving these connections open you’re leaving yourself open to potential troublemakers who can send messages from your Twitter account if they choose.
