WatchGuard: Hafnium Exploit: Important Information You Need to Know
| Last week, Microsoft released a very critical emergency Exchange patch to fix a series of zero day vulnerabilities that attackers could exploit to fully compromise your Exchange server and steal critical information. These flaws pose a severe risk, as state-sponsored threat actors exploited them before Microsoft was aware of the issue, and now the rest of the cyber criminal world is following suit. |
To protect your customers, you should patch all on-premises Exchange servers. However, in the meantime, WatchGuard can help. To learn more about this issue, and what WatchGuard products do to help, please check out our knowledge base article on the subject, as well as this Secplicity post.
