The exploit enables attackers to perform highly privileged actions that typically require a kernel driver. Part 1 of this blog series showed how to block these attacks via ACL hardening. If you haven’t already, please read the first part of this series, because it lays an important foundation for this article. Interested readers can also check out the excellent Unknown Known DLLs...

In our 2021 Security Predictions, the WatchGuard’s Threat Lab team anticipated that authentication would be the cornerstone of strong security. “With billions of usernames and passwords ripe for the picking on the dark web and the prevalence of automated authentication attacks, we believe that any service without MFA enabled will be compromised in 2021,” said WatchGuard CSO Corey Nachreiner.

Following up on our Simulating Filesystem Tree with Billions of Files series, let's imagine that we want to create a filesystem with 1 billion inodes in memory. At this scale, every single byte used to represent the inode will use 1GB of memory. Just with the inode numbers, each with 8 bytes, will use at least 8GB of memory. If we consider, conservatively, that each inode will use approximately 50 bytes of space, it will not be feasible to store this information in memory.

The modern enterprise network is a complex, highly connected ecosystem of hardware, software, services, communication protocols, virtual resources, and people; who all work together to support business operations. IT networks are now the backbones of organizations everywhere, so cyberattacks aimed at breaking down network security are a huge threat for companies and stakeholders.

With the sharp increase in remote working worldwide, companies have endured a proliferation of cybersecurity risks — and, consequently, increased their spending to protect stakeholders.
