On July 14, 2020, Microsoft released a security update related to a remote code execution (RCE) and denial of service (DoS) vulnerability (CVE-2020-1350) in Windows DNS Server (2003 - 2019).

This post continues this two-part blog series on further understanding the differences between macOS and Windows on the system level for effective endpoint security analysis. In Part 1, we covered process events. Here in Part 2, we’ll discuss file and network events. As with Part 1, my hope is to help cybersecurity professionals expand and enrich their experiences on a less familiar platform, ultimately helping them to be better prepared to face differences from past experiences.

How would you compare the Windows and macOS operating systems? In what ways are they similar? Why do they each take different approaches to solving the same problem? For the last 19 years I've developed security software for Windows. Recently, I’ve started implementing similar features on macOS. Since then, people have asked me questions like this. The more experience I gained on these two operating systems, the more I realized they’re very different.

This is the final blog of our three-part blog series on living-off-the-land (LOTL) attacks. If you missed last week’s blog, you can read it here. LOTL attacks are also known as “malware-free” attacks because your own tools are used against you, either to hide malicious activities under a legitimate system process, or to leverage genuine system activities for malicious purposes.

We’re back with part two of our three-part blog series on living-off-the-land attacks. If you missed part one, you can read it here. In a nutshell, living-off-the-land (LOTL) refers to a type of attack where the attacker uses the tools and features that already exist in the target environment to carry out malicious activities. The concept of LOTL is not new, but LOTL and file-less attacks have been gaining popularity over the last few months.

The cybersecurity threat landscape is quickly changing. Administrators have become more cautious when it comes to security and governing access, end users have become tech-savvy and security-aware, and attackers have also raised their game. Living-off-the-land attacks, or LOTL, is one clear trend today, with attackers exploiting preinstalled features and default tools built into system.

Windows Server 2019 ships and installs with an existing level of hardening that is significantly more secure compared to previous Windows Server operating systems. Gone are the bloat of Xbox integration and services and the need for third-party security solutions to fill security gaps. Operating System (OS) hardening provides additional layers of security and preventative measures against both unauthorized changes and access.

In our last release of the PowerShell security series, we talked about how PowerShell could be leveraged by malicious actors to gain unprecedented access to your organization’s critical assets. From enumerating sensitive domain information and carrying out credential-based attacks to running malicious executables in memory (file-less malware), we shined a light on the potential of PowerShell and why it’s an ideal weapon for cyber attackers today.
