Am attempting to open an old device cover (an adapter) and it has these screws (please see attached image, sorry for the bad quality, I couldn't get better focus than this.)

Would really appreciate if someone could guide me identify it and/or point to where to obtain a driver for it. (Or even more awesome if any tips of opening it using any hack without a specialty driver, if possible!)

Update Addendum

Well I am happy to report that — thanks to the help and solution below — I have acquired & successfully opened the Tamper-proof/Security Torx screw using the bit! (see more bad images below, :D Though I notice that a kind contributor has edited my original picture and fixed some text too, thanks!) :)

This is a tamper proof torx screw. There are torx bits with a hole in the center that will remove them, if you are bold you can try smacking the center pin with a punch at an angle (small ones usually snap off) and then a standard torx bit can be used to remove it. Check online and I bet you can find a tamper proof bit kit for under 15$.

Your picture shows a Security Torx screw head. https://upload.wikimedia.org/wikipedia/commons/thumb/9/9b/Screw_Head_-_Torx_Tamperproof.svg/40px-Screw_Head_-_Torx_Tamperproof.svg.png

You can find a good overview on most common screw drives for identification on a specific wikipedia page.
