Beware scams in the wake of the App Store slip-up

Mac users began to have problems opening apps downloaded from the App Store Wednesday morning. This caused messages that the apps were damaged and would need to be re-downloaded from the App Store.
It turned out that the problem was an expired cryptographic certificate at Apple, used to verify the legitimacy of these apps. Apple didn’t renew it in time, and when it expired, App Store apps failed.
