In December 2013, retail superpower Target was the target (hehe) of a massive data breach that could have affected as many as 110 million customers. On Monday, May 5, 2014, the CEO of Target, Gregg Steinhafel, announced that he would be stepping down, no doubt a result of the chaos that engulfed his company in the aftermath of this data breach. Target's CFO, John Mulligan, has stepped in as interim CEO until the position is filled once again.
