WI-FI SECURITY FLAW ID’D

Security researchers have discovered a Wi-Fi network vulnerability that could allow attackers to steal sensitive information or spread malicious software while someone is logged in to a computer or mobile device.

A report published Monday said the breach could only happen if an attacker is within range of the potential victim, but the weakness could affect anyone using a Wi-Fi network, whether at home, the office or at a public coffee shop.

The Wi-Fi Alliance, an industry group, says there’s no evidence that the vulnerability discovered by researcher Mathy Vanhoef has been exploited maliciously. It affects WPA2, a protocol used to secure Wi-Fi networks.

The group says the problem can be resolved through straightforward software updates. Microsoft says it has already deployed patches. Google says it’ll do so in the coming weeks. High court will hear Microsoft search case. The Supreme Court agreed Monday to take on a major dispute over the government’s authority to force American technology companies to hand over emails and other digital information sought in criminal probes but stored outside the U.S.

The justices intervened in a case of a federal drug trafficking investigation that sought emails that Microsoft keeps on a server in Ireland. The federal appeals court in New York said that the emails are beyond the reach of a search warrant issued by a U.S. judge.

Privacy experts say Microsoft and other tech companies have been more willing to push back against the government since the leak of classified information detailing America’s surveillance programs.

Ruby Tuesday going

private. Ruby Tuesday is being acquired for about $146 million in a deal that will take the struggling chain private.

Like other sit-down restaurant chains, Ruby Tuesday has lost customers to cheaper, faster and more casual places. Comparable-store sales at Ruby Tuesday have fallen for six consecutive quarters, and the company has not reported a quarterly profit in two years.

The private-equity firm NRD Capital said Monday that it will pay $2.40 for each share, a 21 percent premium from the chain’s closing price of $1.99 on Friday.

Is HelloFresh better (financially) than Blue

Apron? HelloFresh, the meal-kit startup backed by Rocket Internet that plans an initial public offering in Frankfurt, is telling investors that it’s set to overtake its rival Blue Apron Inc. in the U.S. in the near term.

HelloFresh generated sales of $169 million in the U.S. in the second quarter, up from $141.5 million in the first three months of the year. If the Berlin-based startup can sustain that growth rate, it could top Blue Apron’s revenue in the third or fourth quarter.

Ahead of its planned IPO that aims to raise as much as $357 million, HelloFresh is trying to convince investors it’s better than Blue Apron, which has lost almost half its value since going public in June. The U.S. company has struggled with higher costs and a decline in customers, just as Amazon.com Inc.’s purchase of Whole Foods Market Inc. highlighted the growing competition in the food business.

HelloFresh, active in about nine markets, in August reported an increase in sales and customers in the second quarter while Blue Apron, which sells its boxes only in the U.S., said it is losing clients.
