During the Investigation of a Suspicious Security Critical Event alarm, we discovered credentials had been dumped from the NTDS.dit, which is a database that stores Active Directory data, including password hashes for all users in the domain. By extracting these hashes, it’s possible for an attacker to use tools to gain access to user’s passwords, which allows them to act as any user on the domain, including the administrator.

Now that the sparkle and pop of the Fourth of July’s fireworks has subsided, it’s time for July’s open source vulnerabilities snapshot, your monthly overview of everything new in the always-evolving world of open source security.

We’re excited to announce the release of Teleport 4.3 - new UI, API driven, expanded audit capabilities, and still open source. This version is so significant, we nearly called it 5.0! In this post, we’ll cover the major new features and you’ll see why we called it ‘Teleport’.

The highly anticipated structural update to the MITRE ATT&CK framework was released July 8th, 2020. After a quiet first half of the year, it appears the ATT&CK team has been putting in lots of work into some significant redesign of the framework’s structure. This update introduces a new layer of abstraction: sub-techniques.

Things just got serious. Business Email Compromise is no longer solely the province of chancers and opportunistic Nigerian actors such as the Yahoo Boys. Organised criminal gangs with a high level of professionalism have seen the opportunity and seized it. Security researchers at Agari have published a report detailing their investigations into a Russian cybercrime gang they say have stolen millions of dollars from companies in 46 countries since mid-2019.

We’re excited to announce that the latest release of Calico includes encryption for data-in-transit. Calico is the open source networking and network security solution for containers, virtual machines, and host-based workloads, offering connectivity and security for container workloads. One of Calico’s best-known security features is its implementation of Kubernetes Network Policy, providing a way to secure container workloads by restricting traffic to and from trusted sources.

Controls management and assessments are critical for properly managing a complete information security program. Similarly, evidence collection, management, and approval is vital for proper control based security governance programs in any organization.

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.
