Millions of smartphones, computers and devices using outdated software run the risk of not being able to connect to the Internet because of network certificates.
Follow entrepreneur, the problem is related to the IdentTrust DST Root CA X3 network certificate which is expiring today. This certificate is provided by the non-profit organization Let’s Encrypt, which encrypts the connection between a user’s device and the Internet to try and prevent hackers from stealing information while transferring data.
Typically, when accessing every website whose domain name begins with HTTPS (Secure Hypertext Transfer Protocol), users will be protected by IdentTrust DST Root CA X3 and several other certificates. But after September 30, Let’s Encrypt will stop using this old certificate, i.e. Internet access is also interrupted.
techcrunch Assessment, the problem does not affect most Internet users around the world. However, there are still millions of smartphones, laptops, PCs, game consoles… that are using the old standards, so they can’t access the network without updating to the latest software.
“Computer users running macOS 2016 or windows Consoles with XP SP3 or earlier, PlayStations 4 or earlier that have not had their firmware upgraded, and use applications based on OpenSSL 1.0.2 or later, will not be able to access the Internet.” techcrunch pay attention.
For smartphones, in principle, devices Android 7.1.1 or earlier will be affected. However, Let’s Encrypt extends the certificates on these machines to 3 years, so the problem only affects versions prior to Android 2.3.7 (Gingerbread).
Personal iPhone Daud iOS Versions 10 or earlier may not be able to access the Internet due to the expired IdentTrust DST Root CA X3. Currently, the iPhone 5 is the last iPhone model to stop supporting iOS 10.
Users need to upgrade the device to a newer operating system version to avoid interruptions in Internet access. For products that are too old and not supported to be updated, users should replace them or use them for other purposes that do not require a network connection.
