(Yicai) July 22 -- Chinese cybersecurity stocks such as Oriental Jicheng and Koal Software surged after China was relatively unscathed by last week’s global information technology crash that resulted from a failed software update by CrowdStrike Holdings.

Oriental Jicheng [SHA: 002819], Koal Software [SHA: 603232], and Guohua Network Security Technology [SHA:000004] all jumped by their daily trading limit today, ending 10 percent higher.

Chinese businesses were generally unaffected by the IT outage on July 19 because they use independent vendors for their data security and cloud service needs, ensuring security at the infrastructure and application level, the chief of WPS Office, an office software firm, told Yicai.

Nearly 10 million Windows-based devices crashed around the world last week in the wake of CrowdStrike updating a cloud-based antivirus software that is not sold in the Chinese mainland, resulting in widespread disruptions at banks, airlines, retailers, telecoms companies and other service providers.

Chinese airlines and airports operated normally because they mainly use a passenger system developed by China TravelSky Holding, according to the company. The state-owned firm's core production system is not based on Windows, it told Yicai.

Chinese hotels have not installed CrowdStrike’s software, so chains such as Homeinns and H World Group, the owner of Ji Hotels, were unaffected, said Zhao Huanyan, a senior analyst in the hospitality industry.

But some foreign-funded enterprises were not so lucky. Marriott International and InterContinental said today that their China businesses have now returned to normal.

A person in charge of a Shanghai hospital’s IT department told Yicai that CrowdStrike is largely used by foreign companies in China, and the outage had little impact on the local medical sector.

Although China’s software sector is increasingly strong and independent, companies should take cybersecurity risks seriously and keep improving data security, industry insiders pointed out.
