Microsoft recently published two critical CVEs related to Active Directory (CVE-2021-42278 and CVE-2021-42287), which when combined by a malicious actor could lead to privilege escalation with a direct path to a compromised domain. In mid-December 2021, a public exploit that combined these two Microsoft Active Directory design flaws (referred also as “noPac”) was released.

Enterprises know they need defenses integrated into each aspect of their network while not being an inhibitor to innovation. Digital transformation realized through new 5G-enabled IoT, Operational Technologies (OT) and IT use cases are no exception. Therefore, security teams need to take a closer look at the best technology to support this innovation.

During a recent client engagement for a tabletop exercise (TTX), it became apparent that the client did not have a methodology for tracking indicators and building an incident timeline. The CrowdStrike Services team wanted to provide more information to our client on how incidents can and should be tracked, but nothing was available in the public domain.

In my first blog in this series, we discussed the importance of data to the modern SOC, and the unique approach of ThreatQ DataLinq Engine to connect the dots across all data sources, tools and teams to accelerate detection, investigation and response. We developed the DataLinq Engine with the specific goal of optimizing the process of making sense out of data in order to reduce the unnecessary volume and resulting burden.

The TellYouThePass ransomware family was recently reported as a post-exploitation malicious payload used in conjunction with a remote code execution vulnerability in Apache Log4j library, dubbed Log4Shell. TellYouThePass was first reported in early 2019 as a financially motivated ransomware designed to encrypt files and demand payment for restoring them. Targeting both Windows and Linux systems, TellYouThePass ransomware re-emerged in mid-December 2021 along with other ransomware like Khonsari.
