Target admits it ignored early signs of massive data breach

Target Corp. has acknowledged its security software picked up on suspicious activity after a massive cyberattack was launched, but it decided not to take immediate action.

The acknowledgment comes after Bloomberg Businessweek reported Thursday that Target’s security team in Bangalore received security alerts on Nov. 30 that indicated malicious software had appeared in its network. It then flagged the security team at its home office in Minneapolis.

“Like any large company, each week at Target there are a vast number of technical events that take place and are logged,” said Target spokeswoman Molly Snyder in a statement. “Through our investigation, we learned after these criminals entered our network, a small amount of their activity was logged and surfaced to our team. That activity was evaluated and acted upon. Based on their interpretation and evaluation of that activity, the team determined that it did not warrant immediate follow up.”

She added, “With the benefit of hindsight, we are investigating whether, if different judgments had been made, the outcome may have been different.”

The nation’s second-largest discounter continues to grapple with the fallout of its massive breach since it revealed in mid-December that hackers stole credit card numbers and personal data of millions of its customers. Target announced last week that its chief information officer, Beth Jacob, had resigned and it was searching for an interim CIO. It also said it was working to overhaul some of its divisions that handle security and technology.

Target’s sales, profit and stock prices have dropped in the wake of the massive breach. The retailer reported late last month that its fourth-quarter profit fell 46 percent on a revenue decline of 5.3 percent as the breach scared off customers.

Target’s sales have been recovering as more time passes, but it expects business to be muted for some time: It issued a profit outlook for the current quarter and full year that missed Wall Street estimates because it faces hefty costs related to the breach.
