Xoom, a digital payments company based in San Francisco, disclosed that its systems were exploited for $30.8 million in fraudulent transfers to overseas accounts.

"The incident involved employee impersonation and fraudulent requests targeting the company's finance department," Xoom said in a Jan. 5. filing with the Securities and Exchange Commission.

No customer data or funds were involved in the transfers, and federal law enforcement agencies are investigating the incident, according to the filing.

Additionally, Xoom said that Matt Hibbard, the company's chief financial officer, has resigned from the company, effective immediately.  He will be replaced by Ryno Blignaut, who will serve as acting CFO and chief risk officer.

Blignaut previously served as Xoom's CFO and chief risk officer for nine years, before leaving the company last month, according to the Xoom website.
