Ap­ple has re­leased a soft­ware up­date to iOS and macOS that you should down­load right away.

The se­cu­rity up­date patches a dan­ger­ous vul­ner­a­bil­ity in WiFi chips that al­lows hack­ers to “ex­e­cute ar­bi­trary code”— in­dus­trys­peak for tak­ing over your de­vice. Through the WiFi chip, a hacker may be able to as­sume con­trol of your de­vice’s pro­ces­sor, the cen­tral com­puter that runs everything else.

To take ad­van­tage of the flaw, known as Broad­pwn, all an at­tacker has to do is get within range of your WiFi de­vice, ac­cord­ing to Ni­tay Arten­stein, the se­cu­rity re­searcher at Ex­o­dus In­tel­li­gence who dis­cov­ered the prob­lem and re­ported it. The flaw af­fects mil­lions of Ap­ple and Android de­vices; Google’s Android team re­leased a patch for ear­lier this month. — The Washington Post
