Hackers Have Heavy-Duty Week

Boorstin on The Week of Many Hacks

You know hacking has hit the mainstream when even the biggest names in tech are hit, and when it becomes an Internet meme. And that's exactly what happened over the past week.

It started last Friday when Facebook reported a security breach, although it reassured users no information was compromised.

On Tuesday, Apple had similar news, saying some employee computers were hacked but no data was exposed. The cause of Facebook and Apple's hacking seems to be related to Java software.

Twitter was hacked a few weeks ago in an attack that may have given hackers access to information about 250,000 Twitter uses. But this week hackers went public on the social media site.

On Monday, Burger King's account was taken over, with the rogue Tweeter claiming the burger chain was sold to McDonald's. The following day, Jeep's account was hacked. Its profile page changed to say that the company was sold to Cadillac and offensive comments were tweeted out.

Those accounts were quickly restored and the fake tweets were removed, Twitter is urging users to practice "good password hygiene."

But the real hacks seem to have sparked a fake hack trend. Viacom's MTV and BET tweeted that their accounts were hacked by each other. It turned out to be a marketing ploy, which drew major backlash on Twitter for making light of a serious issue. It's an issue that doesn't seem to be going away.

On Thursday, Donald Trump went public, saying his account was hacked when a Lil' Wayne lyric was tweeted out. It has since been deleted.

Also on Thursday,, CNBC's sister company, was hacked. Security experts warned that malware may have infected the computers of visitors to the site. NBC said it worked quickly to resolve the problem. Security experts advise that users run anti-virus software.

A wide range of companies are working together to figure out the source of the attacks, and to ramp up their protection. No one seems immune.
