Scores of Social Security numbers of employees and volunteers could be in the hands of data thieves, and now the FBI is working to keep them from capitalizing on it.
O'Dea High School will be closed so "staff members will have adequate time to complete the steps necessary to move toward resolving the fraud," O'Dea High School Principal Jim Walker said.
Students at Bishop Blanchet will be dismissed early at 12:35 p.m.
"We will be using the afternoon to address pressing financial and tax matters among our faculty and staff, allowing time for conducting business with financial institutions and agencies open during work/school hours," Bishop Blanchet President Antonio DeSaprio said.
Additional information regarding Seattle-area school closures can be monitored through the students' school website.
The archdiocese learned of the fraud on March 4 and quickly learned at least three parishes and the chancery were affected.
A notice was posted on its website saying several people in their parishes and chancery have become victims of fraud.
The notice says hackers have been able to steal personal information, file fake tax returns and redirect the money to themselves. The archdiocese now has a forensic security firm and the FBI on the case.
To see if you've been a victim of fraud, check with the IRS to see if a return has been filed in your name by going to the IRS website, calling the tax line or going to the local IRS office.
If your information has been compromised, report it to the IRS, check your credit reports and notify police to create an identity theft report.
