WASHINGTON—While numerous analysts have long stated that small institutions, such as credit unions, are becoming bigger targets for hackers, a new warning is being issued to big banks that crooks are zeroing in on their data.
Federal officials are stepping up their warnings to large U.S. banks as some of the biggest institutions have seen an increase in attempted cyberattacks recently, the Wall Street Journal reported.
The Journal reported that regulators have asked banks, including Bank of America Corp., Citigroup Inc., JPMorgan Chase & Co. and Wells Fargo & Co., to closely monitor their networks for criminal activity.
