Archuleta -- whose most recent job was as a national political director for Obama for America, the President's reelection campaign -- was the person to help fix what was an agency already struggling to deal with technology problems and serious data breaches.
Aides to Republican lawmakers who voted for her confirmation now acknowledge they didn't pay enough attention to the importance of technology in the agency Archuleta was taking over.
U.S. investigators believe Chinese government hackers are behind the breach, the worst ever against the U.S. government. Some of the most sensitive security background check data, including information on mental and drug histories of federal job applicants, is now in the hands of Chinese intelligence, according to U.S. authorities.
By the time Archuleta took office, hackers had begun a series of breaches that investigators believe eventually led to the mother lo: the intrusion that began in 2014 and the eventual theft of personal records from two databases.
Archuleta likely wouldn't have known about the earlier breaches before taking office. But she knew enough about the agency's struggles to make this promise in response to written questions provided by senators voting on her nomination: "If confirmed as director of OPM, improved management of OPM's IT, including proper security and data management, will be one of my top priorities."
She also promised to create a plan within her first 100 days to modernize the agency's technology and to appoint a chief technology officer focused on the issue.
Investigators later determined that a roadmap for several of OPM's proprietary software systems was available for some time on an insecure publicly-available website.
Hackers struck the same system again in March 2013. A year later hackers breached a background investigations database. But they had trouble stealing data because OPM's computer systems were outdated. That breach was discovered in July, 2014.
