HP named Jon Hoak, a former NCR general counsel, vice president and chief ethics and compliance officer, replacing former ethics chief Kevin Hunsaker.
In his new role, Hoak will assist outside counsel Barry Schwartz's assessment of HP's current investigative practices and to help develop future best practices, according to HP.
Before coming to HP, Hoak served as senior vice president and general counsel for NCR from 1993 to May 2006. HP CEO Hurd is also an NCR alum.
"HP has traditionally led the industry in adherence to standards of ethics, privacy and corporate responsibility, and with Jon's help, we will lead again," Hurd said in a statement.
Hoak, who started his new role on Wednesday, will report directly to Hurd until a general counsel is hired. "Mark Hurd wanted to make a prompt hire," HP spokeswoman Emma Wischhusen said in explaining why Hoak was quickly hired.
She said Hoak was given the more senior title of vice president to reflect the high-profile position.
Ann Baskins, who was the HP general counsel, resigned in September, hours before she was scheduled to testify before Congress about her part in the spying scandal.
Hunsaker quit his post in September in the wake of revelations about his role in the scandal over tactics used to determine the source of leaks to the media.
