ORTAGE, Mich. (AP) — Stryker, a major U.S. medical equipment company, said a cyberattack disrupted its global networks Wednesday.

“We have no indication of ransomware or malware and believe the incident is contained. Our teams are working rapidly to understand the impact of the attack on our systems,” Stryker said in a statement on its website.

The logo of Handala, a hacking group linked to Iran, has appeared on company login pages, The Wall Street Journal reported.

Stryker’s statement said the cyberattack hit its Microsoft programs. Emails seeking additional information were not immediately answered.

BIG EDIT: I changed the post because I linked an incorrect, out of date article because I had no clue that Iran had previously conducted cyberattacks. Mistake was all mine.
