The amount of alleged losses to fraud victims rose last year according to the Internet Crime Complaint Center.
The unverified losses jumped 8.3 percent from $US485 million in 2011.
While the fraud damages increased, the number of fraud complaints lodged with the group fell from 310,000 in 2011 to 289,874 last year.
The most common complaints involved emails scams impersonating the FBI, "intimidation" incidents and scareware schemes that try to sell fake anti-virus by claiming the victim's computer is infected.
The IC3, a partnership between the FBI, National White Collar Crime Center and Bureau of Justice Assistance, reported the finding in its annual Internet Crime Report.
