Wal-Mart And Facebook To Serve Up Local Offers [Facebook]

Wal-Mart and Facebook are unlikely bedfellows, but here they are cozying up together in a partnership that'll create custom Facebook pages for the retailer's 3,500 stores. This is the first time a retailer has used Facebook in this way.

The idea is to make the shopping experience more personal by letting customers interact with their local Wal-Mart store on Facebook. Customers can visit the Facebook page for their local store and receive product details, event information and sales offers. Customers can even receive a map of the store which will help them find the products on sale.

Not surprisingly, Wal-Mart wants to eventually use your "like" information to personalize the experience for you. That might seem creepy, but at least you guys won't have to receive offers for feminine hygiene products, when all you want is a good deal on rakes. [Associated Press]

Mac OS X Lion Passwords Are Super-Easy to Hack (and Change) by Any Local User [Security]

You're constantly hearing about how you need to make sure to use a secure password, but what are you supposed to do if a hacker can just change your password without even cracking it? That's what users with physical access to your computer can do on OS X Lion right now.

A similar issue in previous versions of OS X allowed Admin users to access the "shadow files" that store OS X passwords, but in Lion, non-Admin users can access the hash and salt data for passwords, which shouldn't be possible. But that's not all—it seems Directory Services in Lion don't require authentication when requesting a password change for the current user, so even if the encrypted hashes aren't cracked, the password can still be changed.

CNET's got a detailed list of ways to lock down your system until Apple releases a patch, but for now, like disabling auto-log-in, enabling sleep and screensaver passwords, and disabling guest accounts; but the long and short of it is that anyone with physical access to a Mac running Lion can access and change your password relatively easily. So be careful with that, eh? [Defence in Depth via CNET via Techmeme]
