Cyber assaults against financial services companies nearly doubled this year, according to a report issued Monday by PwC, formerly Price Waterhouse Coopers.

Twenty percent of the companies surveyed said they had a cyber breach by a competitor in 2014, compared to 11 percent in 2013.

Forty-four percent of the companies said they experienced cyber assaults by employees, up from from 33 percent, and 28 percent had their computers attacked by ex-employees, up from 23 percent.

Hacking incidents by outsiders declined, with 26 percent of companies reporting incidents, down from 36 percent.

The results contrast with reports by federal cyber security officials that most significant cyber attacks are coming from overseas.

Firms that serve as vendors to financial services companies are also potential threats, according to the report. Over 40 percent of the 758 financial services companies surveyed said they had detected breaches by current and former service providers, contractors and suppliers.

“While many financial services companies have detected third-party compromises, most have done little to protect themselves,” the report said.
