Whether or not you made it to RSA 2023, here are two key themes we saw throughout this year’s conference.

We are excited to announce the release of a new detection package “Sliver”, which identifies and raises alerts related to the Sliver C2 framework. This new package joins our industrial-strength C2 Collection and uses a variety of techniques to detect Sliver, above and beyond our HTTP-C2 package’s existing Sliver coverage. In this blog we provide some basics about Sliver and how it works and then dive deep into the techniques we use to detect this popular and powerful tool.

This blog post is the first in a 2 part series on Corelight Smart PCAP. Tune in next week for part two where we’ll take a deep dive look at Corelight’s PCAP functionality and workflows that accelerate security investigations.

We are honored to announce that Corelight’s Open Network Detection and Response (NDR) solution has been chosen by the esteemed Black Hat Network Operations Center (NOC) to help defend their networks at Black Hat events worldwide. It’s a testament to the capabilities of our platform and the open source technologies that power it. We are honored to be among the distinguished vendors chosen to provide best of breed solutions for the NOC.

Comprehensive visibility into network protocols is a hallmark of Zeek (and therefore Corelight) data. That's why we are very happy to announce that with our v27.2 release we are supporting a new analyzer for the LDAP protocol. You likely know LDAP as a workhorse for carrying directory information across the network. While it's an open standard, it's most often seen as part of several server implementations, especially Microsoft's Active Directory, OpenLDAP, and others.

Corelight Investigator furthers its commitment to delivering next-level analytics through the expansion of its machine learning models. Security teams are now enabled with additional supervised and deep learning models, including: We continue to provide complete transparency behind our evidence -- showing the logic behind our machine learning models and detections, allowing analysts to quickly and easily validate the alerts.

Editor's note: This is the first in five-part series authored by Ed Amoroso, founder and CEO of TAG Cyber, which will focuses on how the Corelight platform reduces network security risks to the so-called Everywhere Cloud (EC). Such security protection addresses threats to devices and assets on any type of network, including both perimeter and zero-trust based.

Corelight Labs, our amazing research team, has been hard at work on another content collection which we are excited to introduce: the Corelight Entity Collection. Corelight evidence is powerful and comprehensive. So comprehensive, in fact, that it can sometimes be hard to know where to start. Providing customers faster ways to find meaningful context in our data was the driving force behind the creation of the Entity Collection.

Today, as a part of our v27 software release, we are launching enhanced IDS rules management functionality, extending analyst visibility around hosts, devices, users, and more, and upgrading the Corelight Software Sensor to give customers more NDR deployment flexibility.

As we shared at ZeekWeek 2022 in October, we’re thrilled to announce emerging support for Zeek on Windows, thanks to an open-source contribution from Microsoft. Part of its integration of Zeek into its Defender for Endpoint security platform, this contribution provides fully-native build support for Windows platforms and opens up a range of future technical possibilities in this vast ecosystem.
