By Sophie Van Remortel: Digital Marketing & Content Coordinator


Microsoft has issued an urgent security notice regarding HiveNightmare (also known as SeriousSAM), which is a vulnerability that can allow a regular user unintended administrative access to an organization’s network. This is a low external risk and high internal risk to environments as the information exposed could potentially allow a skilled attacker to run programs and administrative tools with full administrative privilege on any domain computer.  

As of August 6th, 2021 Microsoft has released a workaround solution for systems that are vulnerable to the HiveNightmare security flaw. No patches have yet been released by Microsoft. If you would like more details regarding this vulnerability, they can be found here

SWICKtech will continue to monitor the details of the vulnerability, keeping client’s network and data security top priority. Please contact us if you have questions regarding HiveNightmare or cybersecurity.
