As investigators continue to gather clues about the cyberattacks that hit computers around the world last week, some big companies and other organizations are still reckoning with the damage.

At Mondelez International, a giant maker of snacks, thousands of servers and computers were rendered useless and production lines at some factories ground to a halt. The company said on Thursday that shipping and invoicing had been disrupted during the last four days of the most recent financial quarter, but that a “critical majority” of its systems were back up and running.

Hospitals across the United States have not been able to create electronic records for more than a week after the software maker Nuance Communications experienced significant problems with its computers. On Thursday, it was not clear when all of the company’s systems would be working properly.

Reckitt Benckiser, which makes Lysol spray, lowered its sales forecasts on Thursday, citing disruptions to its supply chain. And at DLA Piper, a global law firm, employees said it might be a while before all systems returned to normal.
