No one is immune from hacks, former Yahoo CEO tells lawmakers

- By Kevin Freking

WASHINGTON >> Former Yahoo CEO Marissa Mayer told lawmakers Wednesday that the threat from statespons­ored hackers has changed the playing field so dramatical­ly that even the best- defended companies can fall victim.

Mayer joined former and current CEOs of Equifax in testifying before a Senate committee examining recent data breaches that affected millions of Americans. Lawmakers said they hoped to use the informatio­n learned to shape future legislatio­n.

In Yahoo’s case, stolen informatio­n for billions of users included names, email addresses, phone numbers, birthdates and security questions and answers. Mayer said the thefts occurred during her nearly five-year tenure and she wanted to “sincerely apologize to each and every one of our users.”

“As we all have witnessed: no company, individual or even government agency is immune from these threats,” Mayer said.

Mayer said Yahoo successful­ly defended itself against a barrage of state-sponsored and private hacks over the years and even employed hackers to test the company’s defenses. In the end,

she said “Russian agents intruded on our systems and stole our users’ data.”

Mayer is part of a long line of company executives and former executives who have made their way to Capitol Hill in recent years to explain how their company fell victim to a cyberattac­k. She was joined by the interim CEO of Equifax, Paulino Barros, Jr., who took over after hackers exposed the personal informatio­n of 145million Americans.

Barros told the committee he has focused on improving customer service and revising the company’s structure so that the company’s chief security officer reports directly to him. He also said the company is on schedule to release a computer app in January that will allow consumers to lock and unlock their credit data.

Sen. John Thune, R- S. D., the committee chairman, said 48 states have separate laws governing how and when companies must notify consumers of a breach. He said a federal law should replace that patchwork of laws.

“A single federal standard would ensure all consumers are treated the same with regard to notificati­on of data breaches that might cause them harm,” Thune said.
