Washington state officials have acknowledged the loss of “hundreds of millions of dollars” to an international fraud scheme that hammered the state’s unemployment insurance system and could mean even longer delays for thousands of jobless workers still waiting for legitimate benefits.

Suzi LeVine, commissioner of the state Employment Security Department (ESD), disclosed the staggering losses during a news conference Thursday afternoon. LeVine declined to specify how much money was stolen during the scam, which is believed to be orchestrated from Nigeria. But she conceded that the amount was “orders of magnitude above” the $1.6 million that the ESD reported losing to fraudsters in April…

Among the criminal groups implicated in the fraud is a Nigerian organization known as Scattered Canary, according to a report released this week by Agari, a California-based cybersecurity firm that has tracked the African organization’s activities. The group has been running scams for more than a decade, working to steal Social Security payments, student aid and disaster relief funds, among other targets, the report said.

The group likely used personal information about Washingtonians from previous consumer-data breaches to slam Washington’s unemployment system with phony claims, which were paid out along with hundreds of thousands of legitimate ones.
