Target Corp.'s chief financial officer is to testify before a congressional committee today after a U.S. Senate report released Tuesday said that the company missed multiple opportunities to prevent the holiday data breach, Reuters reported.


The report said there was no indication that Target responded to warnings that malware was being installed on its system by hackers. The company also ignored other automated warnings that revealed how the hackers would carry data out of the network, the report said.


Today, John Mulligan, Target's executive vice president and chief financial officer, and Edith Ramirez, chairwoman of the Federal Trade Commission, are among witnesses in a committee hearing on how to protect consumer information from cyberattacks.


Target has declined to comment on Tuesday's report until after today's testimony by Mulligan.


Also, Trustmark National Bank and Green Bank NA are suing Target and security firm Trustwave for damages suffered due to the breaches, American Banker reported. The banks are seeking class-action status and damages of more than $5 million.
