Elastic Security Labs is tracking likely multiple on-net threat actors leveraging Exchange exploits, web shells, and the newly discovered SiestaGraph implant to achieve and maintain access, escalate privilege, and exfiltrate targeted data.
Elastic Endpoint Security provides events that enable defenders with visibility on techniques and procedures which are commonly leveraged to access sensitive files and registry objects.
In this research article, we will take a look at a collection of UAC bypasses, investigate some of the key primitives they depend on, and explore detection opportunities.
Elastic Security has identified active intrusions leveraging the newly identified BLISTER malware loader utilizing valid code-signing certificates to evade detection. We are providing detection guidance for security teams to protect themselves.
This blog post provides a summary of CVE-2021-44228 and provides Elastic Security users with detections to find active exploitation of the vulnerability in their environment. Further updates will be provided to this post as we learn more.
Elastic Event Query Language (EQL) correlation capabilities enable practitioners to capture complex behavior for adversary Lateral Movement techniques. Learn how to detect a variety of such techniques in this blog post.
By formalizing stateful detection in your rules, as well as your engineering process, you increase your detection coverage over future and past matches. In this blog post, learn why stateful detection is an important concept to implement.
Our Elastic Security research team has focused on advanced techniques used in a Malaysian-focused APT campaign. Learn who’s behind it, how the attack works, observed MITRE attack® techniques, and indicators of compromise.
