Medical technology maker Stryker Corp., hit by a crippling cyberattack linked to a pro-Iran group, is still investigating the breach and doesn’t know when its systems will be back online.

The company said in a regulatory filing Wednesday afternoon that it expects the breach to continue disrupting operations and “the timeline for a full restoration is not yet known.” In an earlier memo seen by Bloomberg News, the company acknowledged that the attack had pummeled its network.
