Senate investigators accused Target on Tuesday of making serious missteps that allowed hackers to steal millions of credit card numbers from its system.
Target “missed a number of opportunities”¦ to stop the attackers and prevent the massive data breach,” the Senate Commerce Committee aides wrote in a report.
The findings could expose Target to a lawsuit from the Federal Trade Commission, which has sued dozens of companies in recent years for failing to adequately protect customer data from hackers.
Molly Snyder, a Target spokeswoman, said the company’s investigation is ongoing.
“With the benefit of hindsight, we are investigating whether, if different judgments had been made the outcome may have been different,” she said.
The hackers stole credit card numbers for as many as 40 million Target customers between Nov. 27 and Dec. 15 of last year, according to the retailer. The hackers obtained other personal information such as names and addresses for another estimated 70 million customers.
The report comes ahead of Wednesday’s Senate Commerce Committee hearing which will feature testimony from John Mulligan, Target’s chief financial officer, and FTC Chairwoman Edith Ramirez.
The report details how the hackers breached Target’s system and identifies numerous points where Target could have prevent the theft of its customers’ data.
Target gave access to its network to a small Pennsylvania heating and air conditioning vendor, Fazio Mechanical Services, which had “weak security,” according to the report.
The hackers used malware to infiltrate the vendor and then used the vendor’s credentials to access Target’s system, the investors found. Even then, Target could have disrupted the hack if it responded to its internal alerts.
“Target appears to have failed to respond to multiple warnings from the company’s anti-intrusion software regarding the escape routes the attackers planned to use to exfiltrate data from Target’s network,” the Senate aides wrote.
In public financial filings, Target has acknowledged that it is under investigation by the FTC and state attorneys general over the breach.
Senate Commerce Committee Chairman Jay Rockefeller is pushing legislation that would expand the FTC’s ability to crack down on companies for inadequate data security. His bill, the Data Security and Breach Notification Act, would give the FTC the authority to set data security rules and the power to fine companies for violations.
The legislation would also set a national standard requiring companies to notify customers in the event of a breach.
“While Congress deserves its share of the blame for inaction, I am increasingly frustrated by industry’s disingenuous attempts at negotiations,” the West Virginia Democrat said in a statement. “It’s time for industry to work with us on legislation that reinforces the basic protections American consumers have a right to count on.”

The Supreme Court on Monday declined to hear an appeal to the "federal disclosure rules for political advertising," leaving in place the ruling by a lower court upholding a law requiring the disclosure of donors to political ads. The appeal came from "a Denver-based libertarian think tank that wanted to run an ad without being forced to divulge its major donors," which argued that the requirement was a violation of first amendment rights under the Court's Citizens United decision.
