The Splunk Threat Research team has researched two of the current payloads involved in these heinous campaigns against healthcare and first responder organizations such as Conti & REvil. In the first blog, we explored the REvil ransomware group and in this blog, we will explore Conti.

SeriousSAM or CVE-2021-36934 is a Privilege Escalation Vulnerability, which allows overly permissive Access Control Lists (ACLs) that provide low privileged users read access to privileged system files including the Security Accounts Manager (SAM) database. The SAM database stores users' encrypted passwords in a Windows system. According to the Microsoft advisory, this issue affects Windows 10 1809 and above as well as certain versions of Server 2019.

Continuing to ride the waves of Summer of Security and the launch of Splunk Security Cloud, Splunk Security Essentials is now part of the Splunk security portfolio and fully supported with an active Splunk Cloud or Splunk Enterprise license. No matter how you choose to deploy Splunk, you can apply prescriptive guidance and deploy pre-built detections from Splunk Security Essentials to Splunk Enterprise, Splunk Cloud Platform, Splunk SIEM and Splunk SOAR solutions.

The Splunk Threat Research Team has assessed several samples of Trickbot, a popular crimeware carrier that allows malicious actors to deliver multiple types of payloads.

Extended Detection and Response (XDR) has generated a lot of buzz recently with press, analysts, and even customers. There’s no denying that, at face value, its promise of reduced complexity and cost while increasing detection and response is alluring. As security teams look to modernize their security tooling, they’re also looking for solutions to some of their largest challenges. Is XDR the answer? What is XDR, exactly, and how do you determine if it’s right for your organization?

Since last week, I’ve been speaking with Splunk customers and our own team about the cyberattacks impacting the Kaseya software platform. While Splunk was not impacted by the ransomware attack, as a security leader we want to help the industry by providing tools, guidance and support. It’s critical that we work together as a community to counter cybersecurity threats and share information about events like these.

We are super excited to announce updates to Splunk Enterprise Security (ES) with our latest 6.6 release. Get ready for the latest and greatest that Splunk Enterprise Security has to offer. Let's dive right into it.

Splunk was named a Leader for the eighth consecutive time this week in the Gartner Magic Quadrant for Security Information and Event Management (SIEM)*. In our opinion, this recognition marks one of the longest running recognitions in the history of the SIEM market. The recognition comes on the heels of Splunk also being ranked No.

When Splunk told me we would have a “breach holiday” theme for the summer, I didn’t think it would be quite so on the nose… For those of you who have been working on this Kaseya REvil Ransomware incident over the weekend, I salute you. We’ve been doing the same. As usual, my team here at Splunk likes to make sure that we have some actionable material before posting a blog, and this time is no different.

I have often joked that IT, and in particular cybersecurity, is like fashion — not a lot is ever new, just reimagined and, in some cases, improved. As I sit pondering the beauty of my COVID-19 comb-over mullet, I have found myself thinking about how this fashion analogy applies to zero trust.
