Stryker stock down: Medical equipment maker’s systems defaced by cyberattack linked to pro-Iran hackers

Medical equipment maker Stryker was allegedly hit with an Iran-linked cyberattack on Wednesday, right after midnight ET, causing a global outage across its system. Staff and contractors said a logo of an Iran-linked group appeared on the login page, according to The Wall Street Journal, which first reported the news.

Shares of the Michigan-based global medical technology company (NYSE: SYK) were down nearly 4% in early afternoon trading on Wednesday at the time of this writing.
