arget Corp faced a security breach in December which affected 70m customers

Beth Jacob, the chief information officer of US retailer Target Corp, which suffered a security breach said to have affected 70m customers, has resigned.

In a statement CEO and chairman Gregg Steinhafel said the company would be "elevating the role" to a new job of chief information security officer and would hire externally for the position.

"While we are still in the process of an ongoing investigation, we recognise that the information security environment is evolving rapidly," the statement noted.

"To ensure that Target is well positioned following the data breach we suffered last year, we are undertaking an overhaul of our information security and compliance structure and practices at Target."

As part of this effort, the retailer said it will be conducting an external search for an interim CIO as well as a chief compliance officer. 

Steinhafel added: "We are also working with an external advisor, Promontory Financial Group, to help us evaluate our technology, structure, processes and talent as a part of this transformation."

The data breach hit Target's profits in its last financial year. Annual net income for the 12 months to 1 February fell 34% to $1.971bn, while sales dipped 0.9% to $71.3bn.
