Former Yahoo! Inc. Chief Executive Officer Marissa Mayer warned hackers are becoming more potent as she joined Equifax Inc.’s interim CEO in trying to reassure a Senate panel the companies are bolstering their defenses.
Yahoo, which announced last month that a 2013 breach affected far more customers than previously thought, has doubled its security staff, helping to deflect “a barrage of attacks,” Mayer said in remarks to be delivered Wednesday before the Senate Committee on Commerce, Science and Transportation. But the suspected involvement of Russian agents in its breach shows companies still face a formidable challenge, she said.
