On March 25, shares of U.S. medical device maker Stryker Corp. (NYSE: SYK) closed at $346.11 on the New York Stock Exchange, up 5.63%, adding roughly $7.9 billion (₩11 trillion) to its market capitalization in a single day. Following this gain, the company’s market cap stands at about $132.5 billion (₩180 trillion), with regular‐session trading volume reaching 1.16 million shares.

Stryker has been recovering from a March 11 cyberattack by the Iran‐linked hacking group Handala, which severely disrupted its global networks as well as production and logistics systems.

According to security experts, the attack exploited Microsoft Intune to perform remote device wipes, causing widespread data loss. Some reports claim that hundreds of thousands of endpoints were erased in the incident.
