WebConsole Cyber Kill Chain

Tough times call for tough measures. What better way to visualize those measures than through the Cyber Kill Chain? The Cyber Kill Chain is a method developed by Lockheed Martin to gain further insight into what stage a cybercriminal is at in an attacking cycle. Stages include Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control, and Action on Objectives.

SMS Alerting Via SmartResponse

Security analysts can't always dedicate their time to monitoring the security operations center (SOC), nor do they always check the alerts that they receive via email, due to various reasons. Also, some alerts are simply more important than other alerts—important enough that you want to know about them right away and be notified in the most effective way possible, even when out of the office and disconnected from email.

The State of Ransomware: How to Prepare for an Attack

Ransomware is currently one of the most widespread and highest-publicized threats on the Internet. Over the last few years, we’ve seen a marked increase in the use of ransomware tools like CryptoLocker, CryptoWall, TeslaCrypt and more recently Locky. Security experts predict 2016 will follow this trend as more cybercriminals begin offering ransomware-as-a-service options to their list of nefarious wares.

Learn How to Automatically Mitigate Threats

The reality today is that 76% of organizations were compromised by a successful cyber-attack in 2015. With perimeters becoming ill-defined and fluid due to the rise in the adoption of BYOD (bring your own device), cloud services and the mobile workplace, we can no longer rely on building big walls to keep people out. In my use case featurette you’ll see host becoming compromised using a previously undetected attack, and how LogRhythm detects and automatically mitigates this threat in real time.

Detecting and Ending Long-Running Processes

We recently had a challenge arise with administrators connecting to a variety of servers daily and launching a variety of tools. Often, the default action for administrators is to disconnect their session rather than log off. This results in applications left running that consume valuable server resources such as memory and CPU. While there are configuration settings you can put in place to address these challenges, often in a large enterprise, they are not straight-forward as they may seem. So, how can you use LogRhythm to detect these long-running processes?

Monitoring Digitally Signed PowerShell

The purpose of the Execution Policy is not to stop the user from running unapproved applications. Rather, it is a way to prevent an attacker from running scripts that the user hasn't approved. This is an important distinction, because the user who has access to PowerShell can run any commands they like at the interactive prompt. The Execution Policy is not designed to control this—that job is left to the Windows Account Model.

SANS "Find Evil" Digital Forensics Use Case for Windows

In 2014, SANS published a Digital Forensics poster called “Know Abnormal…Find Evil.” This resource delves into the differences between normal and abnormal behavior—and what you might look for or ignore in a digital forensics investigation. Using this reference guide—and other Windows knowledge—you can look for deviation from normal Windows behaviors in real time. This gives you quicker visibility into suspicious activities that try to hide within Windows.

Detecting Rogue Svchost Processes

Malware authors may attempt to hide their processes in plain sight by calling them the same name as common Windows processes. Very commonly, "svchost.exe" has been used for this purpose. It is difficult to catch this by simply looking at a system, because multiple instances of svchost.exe are expected to be running on a typical Windows System. By leveraging LogRhythm's built in parsing support, we can detect rogue svchost processes.
