One of the most commonly used techniques is to dump credentials after gaining initial access. Adversaries will use one of many ways, but most commonly Mimikatz is used. Whether it be with PowerShell Invoke-Mimikatz, Cobalt Strike’s Mimikatz implementation, or a custom version. All of these methods have a commonality: targeting LSASS.
If you haven't heard the gospel of risk-based alerting (RBA) in a SIEM context, by the end of this sermon you'll see why you’ll want it running in your environment yesterday, whether you're an analyst, an engineer, or in leadership.
As the trend toward having a more distributed labor force working remotely part or full time persists, Splunk continues to see strong customer demand for more visibility into the security of the productivity and collaborative products their employees use.

This second major release includes important changes requested by our customers and valuable new functionality.
As the conflict in Eastern Europe continues, the Splunk Threat Research Team (STRT) is constantly monitoring new developments, especially those related to destructive software. As we have showcased in previous releases in relation to destructive software and HermeticWiper, malicious actors modify their TTPs in order to become more effective and achieve their objectives.
The Splunk Threat Research Team is actively monitoring the emergence of new threats in the cyber domain of ongoing geopolitical events. As we have shown previously in several releases, including HermeticWiper and CaddyWiper, actors in this campaign are deploying, updating, and modifying stealthier malicious payloads. On March 17th, 2022, the Ukraine CERT discovered a new malicious payload named DoubleZero Destructor (CERT-UA #4243).
Do you feel like every other cybersecurity news story mentioned ransomware in 2021? Does it feel like you can’t turn on a cybersecurity podcast and not hear the “R” word? We feel the same way, and as a cybersecurity vendor, we felt that we should also contribute to the noise. :-) But we did want to try and do something different.
As stated in our previous threat advisory STRT-TA02 in regards to destructive software, past historical data suggests that for malicious actors to succeed in long-standing campaigns they must improve and add new ways of making their payloads stealthier, resistant, and damaging. HermeticWiper introduces some unique features, applying destructive actions on compromised hosts.
