Dish Network Corp. shares slumped to their lowest level in more than a decade after the company said some data had been stolen in a recent ransomware attack. Separately, Bank of America downgraded the stock to underperform.

Dish learned on Monday that some data, including potentially personal information, was extracted from its IT systems as part of an earlier cyberattack, according to a company filing. While Dish, Sling and wireless and data networks remain operational, the company said in a filing Tuesday that its internal communications, customer call centers and Internet sites have been affected.
