A serious vulnerability was found in PHP, leading to a series of temporary shutdowns of Japanese companies' websites. In the United States, by contrast, many companies continued operating without being affected.
Articles from Silicon Valley and New York report that a serious vulnerability was found in the programming language PHP, affecting websites around the world. While some Japanese companies temporarily shut down their websites, companies in the United States, where the vulnerability's impact was relatively limited, are reported to have continued operating their sites. The nature of the vulnerability, the scope of its impact and differences in how companies responded are drawing attention.
The reports also say that, in terms of defensive measures, the US government and technology companies worked together to respond swiftly. In Japan, the speed of the response and the degree of coordination remain subject to further reports. Companies say they are updating to the latest version and strengthening monitoring, and further details of the incidents are expected to emerge in future news reports.
