The Federal Reserve Bank issued a notice Tuesday telling banks to assess their cybersecurity postures and search for clues that they'd been victims of cyberattacks by the same group that pulled off an $81 million cyber heist from the Bangladesh Central Bank account at the Fed.
The Fed's alert, which Fortune said was reportedly seen by Reuters, was not the only warning issued by regulators this week regarding a series of hacks leveraging the Society for Worldwide Interbank Financial Telecommunication (SWIFT) financial messaging service platform to carry out attacks against financial institutions.
The Federal Financial Institutions Examination Council issued a statement that urged financial institutions to “review their risk management practices and controls over information technology and wholesale payment systems networks, including authentication, authorization, fraud detection, and response management systems and processes.”
SWIFT CEO Gottfried Leibbrandt in May announced details to reinforce the security of the messaging services.

Symantec identified three pieces of malware that were used in limited targeted attacks against the financial industry in South-East Asia and include Backdoor.Fimlis, Backdoor.Fimlis.B, and Backdoor.Contopee, according to a May 26 blog post.
Researchers said the Backdoor.Contopee malware was linked to the Lazarus cybergang who used a different malware in attacks against Sony Pictures Entertainment in 2014.
