Yahoo Hack Throws Internet Insecurity into Sharp Relief

Article excerpt

Even in an era of massive data breaches, the one announced by Yahoo this week was spectacular and raises worrisome questions about the continued vulnerability of America's digital networks to increasingly sophisticated adversaries.

Yahoo on Thursday announced that a state-sponsored adversary had broken into its networks and stolen the names, email addresses, phone numbers, birth dates, passwords, and security questions belonging to a staggering 500 million user accounts.

The announcement confirmed earlier rumors about a potential breach at the company. In August, a cybercriminal named "Peace" announced he had put some 200 million Yahoo credentials for sale on the Dark Web. Yahoo had said it was aware of the hacker's claim but did not confirm it had been breached.

Peace has put hundreds of millions of similar user credentials stolen from LinkedIn, MySpace, and Tumblr up for sale earlier this year. The data was obtained from intrusions at these firms over the past two or three years.

Yahoo said the intrusion into its network occurred sometime in late 2014 but offered no explanation on why it was disclosing the breach only now, two months after agreeing to sell its core business to Verizon for $4.8 billion.

Just this week, for instance, White House officials said that they are investigating reports that hackers leaked First Lady Michelle Obama's passport details and vice president Biden's travel schedules online.

The breaches come at the time when spending on information security is higher than ever. The technology research firm Gartner expects worldwide information security spending to top $81 billion in 2016, up nearly 8 percent from last year.

As organizations such as Yahoo continue to get breached in spectacular fashion, modern enterprises face enormous challenges in stopping hackers. …
