What is the biggest threat of fraud to the Social Security system?

According to former Social Security Commissioner Martin O'Malley, the biggest threat is not fraudulent payments as often claimed, but rather identity theft. During his tenure, he discovered that the primary concern was people attempting to steal individuals' identities to hijack personal information. This finding contradicts common misconceptions about Social Security fraud. Rather than people wrongfully collecting benefits, the more pressing issue is protecting citizens' personal data from those who seek to compromise identities for various fraudulent purposes. This insight helps redirect security efforts toward data protection rather than just payment verification.
