A serious security flaw disclosed in PHP, a programming language widely used to run websites, has affected financial institutions, companies, local governments and central government agencies in Japan, according to an Odaily report citing Jin10. Speaking at a press conference on the morning of Oct. 22, Japanese Chief Cabinet Secretary Minoru Kihara said no damage reports had been received so far. He urged companies and other organizations to apply patches and said the government would keep a close watch on developments and respond as needed. Kihara also said some government departments, including the Ministry of Health, Labour and Welfare and the Ministry of Finance, had temporarily stopped publishing parts of their website content as a precaution. Following the incident, Japanese cybersecurity-related stocks moved higher, while the foreign exchange market and the yen bond market showed no obvious volatility.

A nasty security hole in PHP — the programming language that powers websites — has hit financial institutions, companies, local governments and government agencies in Japan, Odaily reported, citing Jin10.

Speaking at a press conference on the morning of Oct. 22, Japanese Chief Cabinet Secretary Minoru Kihara said, "As of now, we have not received any reports of related damage." He also urged companies and other organizations to install patches, and said the government would keep a close watch on the situation and take appropriate measures.

Government departments take precautionary steps

Kihara said government departments, including the Ministry of Health, Labour and Welfare and the Ministry of Finance, have temporarily stopped publicly posting some parts of their website content as a precaution. A defensive move. Simple as that.

Market response

After the incident, Japanese cybersecurity-related stocks moved higher, while the foreign exchange market and the yen bond market showed no obvious swings.
