The US government on Tuesday told banks to include details about cyber attacks when filing mandatory reports on fraud and money laundering, saying that will help battle digital crimes that pose "a significant threat" to the US financial system.
The US government has long required banks to submit confidential reports known as suspicious activity reports, or SARs, in fraud cases involving at least $5,000.
The Treasury Department's office of Financial Crimes Enforcement Network, or FinCEN, released an advisory that specifies what details banks should include in SARs when there is a cyber element in the case.
"The bank should include all available information," FinCEN said in the advisory. That includes describing how the system was breached, IP addresses of computers used by hackers and device identifiers.
