Galaxy S4

Truth be told, the Samsung Galaxy S4 hardware isn’t really the star of the show. But that’s not to say the Galaxy S4 specs aren’t impressive. They most certainly are, and it’s even more impressive considering that Samsung’s built everything into a device that’s in nearly the same footprint as its predecessor, the Galaxy S3.

On the hardware side, there’s really nothing too surprising. The Galaxy S4 broad strokes are a 5-inch display, 2 gigabytes of RAM and Samsung’s usual mix of physical and capacitive buttons.

facebook hacking

Remember the last OAuth Flaw in Facebook, that allow an attacker to hijack any account without victim’s interaction with any Facebook Application, was reported by white hat Hacker ‘Nir Goldshlager‘. After that Facebook security team fixed that issue using some minor changes.
Yesterday Goldshlager once again pwn Facebook OAuth mechanism by bypassing all those minor changes done by Facebook Team. He explains the complete Saga of hunting Facebook bug in a blog post.
As explained in last report on The hacker News, OAuth URL contains two parameters i.e. redirect_uri & next, and using Regex Protection (%23xxx!,%23/xxx,/) Facebook team tried to secure that after last patch.
In recent discovered technique hacker found that next parameter allow facebook.facebook.com domain as a valid option and multiple hash signs is now enough to bypass Regex Protection.
He use facebook.com/l.php file (used by Facebook to redirect users to external links) to redirect victims to his malicious Facebook application and then to his own server for storing token values, where tokens are the alternate access to any Facebook account without password.
warnning
But a warning message while redirecting ruin the show ! No worries, he found that 5 bytes of data in redirection URL is able to bypass this warning message.

Example:  https://www.facebook.com/l/goldy;touch.facebook.com/apps/sdfsdsdsgs (where ‘goldy’ is the 5 byte of data used).

Now at the last step, He Redirect the victim to external websites located in files.nirgoldshlager.com (attacker server) via malicious Facebook app created by him and victim’s access_token will be logged there. So here we have the final POC that can hack any Facebook account by exploiting another Facebook OAuth bug.

This bug was also reported to Facebook Security Team last week by Nir Goldshlager and patched now, if you are a hacker, we expect YOU to hack it again !

Recently there were a bunch of videos going around the net about some of the greatest pickpockets in the world. Simply put, if they wanted something you had, they were going to take it and you probably wouldn’t notice. I’ve always kept my wallet in my front pocket, and usually with my hand on it, but they even showed them getting around that in the video (you can’t always be vigilant).

I had the idea to make some kind of alarm that would go off if anyone but me removed the wallet from my pocket. A quick google search revealed tons of wallet alarms, but I noticed that they all had a credit card form factor(that’s good) and would make noise when exposed to light(that’s bad). This represents a problem since the pickpockets in the videos tended not to open the wallets till later at another location. I needed something that would make noise as it was removed from my pocket. Most importantly, I needed the alarm to be located inside the wallet. This immediately makes the wallet undesirable and will hopefully make someone drop it like hot coals.

 

I happened to have a few little magnetic window alarms sitting around. They’re just a loud buzzer with a magnetic reed switch.  After holding one up to my poor fat old neglected wallet, I saw that the alarm was roughly the same thickness as all the old business cards I should’ve cleaned out of my wallet anyway.

I promptly tore the alarm apart and started planning how I was going to slim it down as much as possible.  Most of the thickness is from the case, the batteries would be the next biggest contributor.  After destroying the buzzer from one by trying to pry it from its plastic enclosure, I decided to leave the buzzer and simply live with the thickness. After all, if the prototype worked well, I could design something in a credit card form factor later. That is, if my attention span were long enough to do a thing like that.

The only real modification I made to the alarm itself was to un solder the reed switch and relocate it to the very end of the whole mess. This would allow it to be at the “spine” of the wallet and keep the power switch at the opening for easy access. The rest was simply cutting away as much bulk as possible and hot gluing things together.

It actually works exactly as expected. There are two choices for the alarm, a single chime when removed, or a constant alarm. The only big upgrade that I would suggest would be a stronger magnet so it wouldn’t need to be aligned perfectly.

solar-powered-cattle-crossing-gate

Anyone who’s traveled the grounds of a cattle ranch will tell you there’s a lot of stopping to open and close gates. But this project is aimed at letting you operate the gate from the comfort of your vehicle. It uses a spool of wire as the gate, lowering it for vehicle access with the use of a remote control.

The base station uses a solar panel to keep the battery topped off. But if you’re not frequently using the system it shouldn’t take much electricity at all. An Arduino board listens for the signal from the remote control. It then unspools the wire until it lays flat across the ground and can be driven over. Once the car has passed another click of the remote raises the gate back into position. There’s even a version that uses two gates which make up a cattle corridor.

We were thinking that it would be easy enough for the cows to push right through this. But after seeing the clip after the break it’s obvious they like to follow the rules.
