A New York court has ruled that Zurich, Sony's insurer at the time of its massive PlayStation hack, is not obligated to defend the company in lawsuits stemming from the breach.

Zurich American Insurance Co. and Sony have been embroiled in an ongoing lawsuit for years, as the insurer sought immunity from covering Sony after its 2011 breach. Zurich argued that it was not liable to indemnify Sony for lawsuit costs, since Sony's policy only covered claims for bodily injury, property damage or personal and advertising injury.

On Feb. 21, a New York state trial court judge ruled that Zurich was not responsible to come to Sony's aid for more than 50 class-action complaints filed against the electronics giant.
