Mind the MPLog: Leveraging Microsoft Protection Logging for Forensic Investigations

In an incident response investigation, CrowdStrike analysts use multiple data points to parse the facts of who, what, when and how. As part of that fact-finding mission, analysts investigating Windows systems leverage the Microsoft Protection Log (MPLog), a forensic artifact on Windows operating systems that offers a wealth of data to support forensic investigations. MPLog has proven to be beneficial in identifying process execution and file access on systems.

You Didn't Ask? Well, the SOC Evolution Answered Anyway

Let me begin by stating the obvious: The cyberattack surface is growing exponentially and diversely. Essentially, it’s a bigger shark and we’ve got the same small boat. The environments, platforms, services, regions and time zones that constitute modern enterprise operations and drive digital transformation for business continue to require increasing specialization and expertise beyond current in-house capabilities.

Approaching Linux Post-Exploitation with Splunk Attack Range

With the recent release of Sysmon (System Monitor) for Linux by Microsoft, new opportunities for monitoring, detection development, and defense are now possible. Sysmon for Windows is a very popular tool among detection developers and blue teamers as it provides extensive details from system activity and windows logs. Due to the extensive information this service/driver provides in Microsoft Windows, it is very useful when researching attacks and replicating malicious payloads on lab machines.

Technical Advisory: Zero-day vulnerability in Apache Log4j Library Allows Remote Code Execution

On December 9th, 2021, Apache disclosed CVE-2021-44228 (colloquially referred to as Log4Shell), a remote code execution vulnerability in the Apache Log4j library, a Java-based logging tool widely used in applications around the world. A highest possible severity score of 10 has been assigned to this exploit.

Detecting Malware Script Loaders using Remcos: Threat Research Release December 2021

Nowadays, malware used to have several stages before it fully compromised the targeted host or machine. The very well-known initial stager is the “phishing email” that contains a malicious macro code or malicious URL link that will download either the actual loader or the next stager to download the actual payload.

Six Pillars of DevSecOps

DevOps and Security. One encourages speed, agility, iterative learning, enabling technology to keep up with the pace of business. The other wants to keep you safe, slows things down, crosses all the T's and dots all the I's. They seem to be at odds with one another — but do they need to be? DevSecOps says no, that’s not the way it has to be.

Devo's 2022 Cybersecurity Predictions: Part Two

In part one of our 2022 cybersecurity predictions series, Devo CSO Gunter Ollmann explained the rise of XDR, the detection-as-code and response-as-code movement, and the growing interest in security tools with built-in, on-demand expertise. In this second installment of our series, I share my take on how the cybersecurity landscape will evolve. Let’s dive into it.

What Is Data Logging?

Humio is a CrowdStrike Company. Data logging is the process of capturing, storing and displaying one or more datasets to analyze activity, identify trends and help predict future events. Data logging can be completed manually, though most processes are automated through intelligent applications like artificial intelligence (AI), machine learning (ML) or robotic process automation (RPA).

Simulating, Detecting, and Responding to Log4Shell with Splunk

For more information on how to respond to the Log4j vulnerabilities using Splunk products, please see our Log4Shell response overview page. Like most cybersecurity teams, the Splunk Threat Research Team (STRT) has been heads-down attempting to understand, simulate, and detect the Log4j attack vector. This post shares detection opportunities STRT found in different stages of successful Log4Shell exploitation.
