A memo seen by KrebsOnSecurity that the Secret Service sent to field offices around the United States this week says the ring has been filing unemployment claims in different states using Social Security numbers and other personally identifiable information (PII) belonging to identity theft victims, and that “a substantial amount of the fraudulent benefits submitted have used PII from first responders, government personnel and school employees.” Continue reading U.S. Secret Service: “Massive Fraud” Against State Unemployment Insurance Programs→
