Linda McClasson reports:

A Michigan-based metal supply company is suing Comerica Bank, claiming that the bank exposed its customers to phishing attacks.

A lawsuit filed by Experi-Metal Inc. (EMI) in Sterling Heights, MI alleges that Dallas-based Comerica opened its customers to phishing attacks by sending emails asking customers to click on a link to update the bank’s security software. EMI says even though the bank had two-factor authentication using digital certificates for its online banking portal, the phishing scam was able to circumvent these measures.

EMI contends that Comerica’s actions opened its online bank account to a successful phishing attack where more than $550,000 was stolen from the company’s bank accounts and sent overseas.

News of this suit comes days after news of another Dallas-based bank, PlainsCapital Bank, suing one of its customers in a dispute over a similar hack.

EMI is but one of many companies across the U.S. being targeted by hackers in this fashion.
