Beloved tv dad, ni nightly news begins right now. Announcer from nbc news World Headquarters in new york, this is nbc nightly news with lester holt. Good evening, theres late word from yahoo tonight of a massive and stunning security breach. The company revealing that hackers may have stolen the personal information from more than a billion yahoo users. The hack apparently occurred over three years ago, but is just now being made public. Whats more, the eyepopping breach is apparently separate from the major attack announced by the company just a few months ago. Nbcs Miguel Almaguer has late details. In what is one of the largest hacks in u. S. History, today yahoo confirms data from more than one billion User Accounts was stolen in 2013. Private names, email addresses, telephone numbers, dates of birth, even encrypted security questions and answers have been exposed. The scale of this attack is something that weve never seen before but were going to keep seeing these things. Because now the internet has been around a long time. Scrambling to identify the person or group who penetrated their firewalls, tonight the internet giant says weve taken steps to secure those User Accounts and were working closely with law enforcement. But this isnt the first attack. Three months ago yahoo revealed another massive breach. When at least 500 million users had their account information stolen. Suspicious a Foreign Government may have been involved that hack is still under investigation tonight. Once a hacker gets your information from yahoo, they can use that to get into other things that are going to make money for the hacker. Though its believed no bank account or credit card information was stolen, Security Experts say your other accounts, like online banking, that use the same passwords, could now be at serious risk. So yahoo says change all your passwords now. Tonight at least one billion users are vulnerable, and so is their private information. Miguel almaguer, nbc news, los angeles. Now an nbc news exclusive, what intelligence Officials Say is evidence the russian effort to disrupt the u. S. Election went all the way to the top. Naming president Vladimir Putin, a former kgb chief, an active player in the Cyber Operation that targeted democrats and the Hillary Clinton campaign. Weve learned new details about what officials believe motivated the plot. Nbcs Senior Investigative correspondent Cynthia Mcfadden tells us more. Tonight nbc news can report that Vladimir Putin was personally involved in the russian attempt to disrupt the u. S. Election. Two Senior Intelligence officials with direct access to all the information tell nbc news the new intelligence is derived from diplomatic sources and others including spies working for americas allies. Specifically, a highlevel intelligence official tells nbc news putins role was directing the use of the hacked material. Putins objectives were multifaceted. What we again as a vendetta gas Hillary Clinton morphed into a an effort to show corruption in american politics and creating an image that other countries couldnt depend on u. S. To be a credible Global Leader any more. Hes had a vendetta against Hillary Clinton, thats been known for a long time. He wants to discredit american democracy and make us weaker in terms of leading the liberal democratic order. And most certainly, he likes president elect trumps views on russia. Now it sounds like we have evidence to support those hypothesis. So tonight the question, will the u. S. Retaliate against mr. Putin directly . Sass part of its plan, u. S. Intelligence dug into mr. Putins personal empire and concluded that his network controlled some 85 billion worth of assets. Left centre. Cynthia, thank you. Paying more for anything is rarely good news. But those who track the economy say todays announcement by the fed that its racing a key Interest Rate after years of historic lows, is yet another sign the economy is on the upswing. For only the second time since the great recession, the Federal Reserve bumped up the rate banks charge each other. Raising it a quarter point. But as tom costello tells us, it will have an effect on all of us and what we pay for a lot of things. For the second time in a decade, the Federal Reserve raises overnight lending rates. Todays quarterpoint rate hike a vote of confidence that the economic recovery is real. While raising rates slowly, the fed is giving itself room to lower rates again should the economy stumble. We expect the economy will continue to perform well with the job market strengthening further and inflation rising to 2 over the next couple of years. Higher rates mean borrowing will become modestly more expensive. Affecting credit cards, shortterm loans, federal Student Loans and new car loans. Also affected, mortgage rates, which for years have been sitting near record lows. The beautiful hardwood floors. This womans realtor told her to expect a rate hike, so she and her family just closed on their first house in new york. Just in time. We locked in an Interest Rate of 3. 75. As of friday, the Interest Rates are 4. 75. Thats a 200amonth difference. If you took out a popular Adjustable Rate Mortgage when rates were low, now is the time to lock in a fixed rate. You want to insulate yourself from the Interest Rate increases. Higher rates could be good news for anyone with cds or anyone on fixed incomes dependant on Interest Rates. If the investments you have are Interest Rate dependant, your increases will be minimal. The cordellos say their house payments will be cheaper than the rent they were paying. The days of cheap money may be coming to an end as the economy picks up steam. The consensus at the feds is they will raise rates three more times in 2017. Much of that could depend on the trump administrations effects on the economy. Lefter in. Tom costello, thanks, tom.

If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt and pe blood clots. Plus had less major bleeding. Both made eliquis the right treatment for me. Ask your doctor if switching to eliquis is right for you. I used to be with verizon, but i switched to sprint.

Some 40 million americans use the popular ridesharing app, uber. But the company is now facing sharp criticism after a lawsuit by a former employee accuses uber of allowing workers to Access Private information to spy on customers. Tonight, hes speaking out in a tv exclusive with nbcs joelynn kent. Uber has become a nearly 70 billion business by offering a convenient way to order up a ride on your smartphone. But a former employee now says the companys lax security allowed thousands of employees who had no need, to track customers trips without their knowledge. What i witnessed, there were some real problems with the safety associated with the protection of that data. I would say you know, youve got to stop. Former security engineer ward spangenberg alleges in a lawsuit between march 2015 and february 2016, workers were able to quote track highprofile politicians, celebri celebrities and even personal acquaintances of uber employees, including exgirlfriends, boyfriends and exspouses. I could print it out on a spreadsheet. Spangenberg was fired after 11 months at uber he says for raising these privacy concerns. Uber tells nbc news he was fired for inappropriately accessing data himself. I wont tolerate data access abuse at uber and ive helped build out systems at uber that will detect abuse if it happens. Spangenberg denies accessing data inappropriately and says that was not the reason given when the Company Fired him in a statement to nbc news, uber says, its absolutely untrue that all or nearly all employees have access to customer data. With or without prior approval. We have built entire systems to implement technical and administrative controls that limit access to customer data. All potential violations are quickly and thoroughly investigated. Uber tells nbc news it was adding controls before spangenberg started at uber and continues to do so today. I want people to be conscious of the fact that we are giving away our information and allowing ourselves to be tracked. If youre worried about protecting your whereabouts, uber is still an option, simply turn off the Location Services function and input manually your address and your destination.
