Chase Bank is investigating a wave of check fraud incidents spurred by a viral social media “glitch” trend, which falsely suggested that users could withdraw unlimited cash from ATMs after depositing fake checks. The bank has referred these cases to law enforcement.

The viral trend, which began on platforms like TikTok, encouraged users to commit fraud by withdrawing funds against fraudulent checks. Within 24 hours, many involved users saw their accounts blocked. A Chase spokesperson emphasized that depositing fake checks and withdrawing money is fraud, regardless of online claims.

The Wall Street Journal reported that Chase is reviewing thousands of cases, and there was a technical error allowing customers to temporarily withdraw full amounts before checks cleared. The glitch has since been fixed.

The severity of check fraud penalties varies by state, with potential jail time and financial penalties, depending on the case.
