A widely used digital certificate that verifies secure internet connections is set to expire on September 30th, leaving millions of older devices, such as SmartTVs, phones, and video game consoles, at risk. Updates to address this issue are available, but if they are not implemented before the 30th, devices may have permanent connectivity issues.
The certificate at hand is called DST Root CA X3, which cross-signs with the even more commonly used ISRG Root X1 certificate. Root certificates are considered a backbone of encrypted web usage, and their expiration could lead to entire chains of certificates failing, wreaking havoc across the internet.
