According to Forrester Research, “How do we reduce our SIEM ingest costs?” is one of the top inquiries they receive from clients. Many security organizations rely on SIEMs for their detection, investigation, and response workflows, ingesting critical security information and events to detect and respond to threats.

MITRE’s Caldera is a cybersecurity platform developed to simulate adversarial tactics, techniques, and procedures (TTPs). Built upon the MITRE ATT&CK framework, Caldera is an open-source tool designed to help cybersecurity professionals and organizations assess their defenses, uncover vulnerabilities, and enhance their overall security posture. By emulating real-world cyber threats, Caldera enables blue teams to test detection and response mechanisms under realistic conditions.

How Corelight Open NDR secures cloud workloads beyond runtime security tools.

Working in the network operating center (NOC) at Black Hat Europe, we’re never quite sure what we’re going to see. The anxiousness I feel there is similar to what I’d experience when I was blue-teaming for a corporate network. I could prepare all I wanted, read all the blogs about the current threat trends people and companies were tracking on the Internet, and review all the red team and vulnerability scanner reports to identify likely targets.

For SOC teams, the battle against cyber threats can feel like trying to solve a 3D jigsaw puzzle in a bouncy house with missing pieces and a timer blasting every few seconds. Despite the increase in security spending, most teams still struggle with inefficient investigations, alert fatigue, and the non-stop guessing game of prioritizing threats. That’s why we’re excited about our latest integration with Microsoft Security that we hope will help address these persistently common challenges.

If there’s one thing I love more than delivering great products, it’s delivering great food. The holidays are my time to channel my inner celebrity chef: I’ll burn a few cookies, over-spice a roast, and then miraculously pull it all together for a meal that leaves everyone asking for seconds (or at least not asking for the takeout menu).

Malicious files continue to be a significant threat to organizations; SonicWall reported more than six billion malware attacks in 2023. To help organizations prepare for and stay ahead of these threats, we’re introducing an integration with YARA that offers a deeper level of inspection for files across enterprise networks while helping security teams consolidate their toolset in the process.

The Verizon 2024 Data Breach Investigations Report found that system intrusion is the leading attack pattern for the third consecutive year, accounting for 36% of breaches. System intrusion largely consists of a threat actor using hacking techniques and malware to infiltrate the victim organization. Following a successful intrusion, the attacker continues on a multi-stage process: The longer an attacker remains undetected, the greater their opportunity to find a target and extract data.

Over the past year, several sophisticated cyber-espionage campaigns have grabbed the attention of our industry and challenged defenders and vendors alike with advanced tactics, techniques, and procedures (TTPs). One of the most visible campaigns is Volt Typhoon, named by the Microsoft threat intelligence team in May 2023 and attributed to Chinese state-sponsored threat actors.

Welcome to Corelight Labs' latest hunt! This blog continues our tradition of analyzing trending threat groups and TTPs on Any.Run and writing detectors for them, providing the community with open-source threat intelligence, and acting as a tutorial in engineering threat detections with Zeek Script.
