More than 80 US government websites have now become either insecure or inaccessible due to the sites not updating a security credential known as a TLS certificate, according to a report by Netcraft.

Sites impacted include the likes of NASA, the US Department of Justice, and the US Court of Appeals.

Most of these affected sites will allow users to proceed past the security warning page, but that can leave users vulnerable to cyber attacks.

The US government shutdown has taken a toll on public spaces — with garbage and human feces overflowing at National Parks — but now the deterioration is being felt online.

Most of the affected sites (like this NASA site) will allow users to proceed past the security warning page, but according to Netcraft, that can leave users vulnerable to attacks.

For instance, if a connection is not secure, websites can be impersonated and sensitive information (like credit card numbers and passwords) can be stolen if entered into the fake site.
