Microsoft inadvertently forgot to renew the SSl certificate of its Microsoft Exchange software, which had the consequence of making the administration portal inaccessible since
As of yesterday afternoon, the admin.exchange.microsoft.com site was no longer functioning correctly, since it displayed warnings to anyone who tried to connect. Indeed, the administration portal indicated that the connection was not private , since the SSL certificate had expired.
SSL certificates are small data files that digitally bind a cryptographic key to an organization’s data . SSL certificates allow websites to switch from HTTP to HTTPS, which is more secure. Typically, SSL is used to secure credit card transactions, data transfer, and connections. More recently , it has become the standard for safe browsing on many sites , such as social networks.
MICROSOFT IS AWARE OF THE PROBLEM, AND IS WORKING TO CORRECT IT.
Questioned on social networks by angry users surprised that Microsoft could have forgotten to renew the certificate, the American giant announced that it would solve the problem shortly. Not all browsers react in the same way to the absence of the certificate, since Google Chrome completely prevented you from accessing the site, while Firefox warned you that the connection was not secure.
Recently, Microsoft Exchange has been the subject of another more serious controversy . Indeed, Exchange business email has been the victim of Chinese hackers, who have managed to steal data from 30,000 organizations . According to information from Krebson Security, a cybersecurity specialist, these hackers were mandated by the Chinese government .
It is not known whether the failure to renew Exchange’s SSL certificate is due to human error, but it appears to have impacted many users. Since then, Microsoft has announced that the certificate had been renewed , and that people should not encounter problems connecting.
