Detects execution patterns associated with the DragonReturn loader, which implements a timing delay loop using GetTickCount64 before executing secondary actions, such as deploying a Windows service via sc.exe.
Detects potential data exfiltration (CVE-2026-42824) where an attacker leverages an SSRF vulnerability in Bing's search-by-image functionality to relay sensitive M365 Copilot data. The rule identifies outbound network requests to the image search endpoint containing a suspicious 'imgurl' parameter pointing to non-Microsoft infrastructure, initiated by common web browser processes.
Detects malicious Parameter-to-Prompt (P2P) injection attempts targeting Microsoft 365 Copilot by monitoring search query parameters for indicators of natural-language command injection or HTML-based payload injection (e.g., img tags, source manipulation, or data extraction commands).
This rule detects attempts to exploit Microsoft 365 Copilot through prompt injection, where attackers inject HTML/script elements into search queries. It specifically identifies when these queries attempt to force Copilot to interact with external URLs via Bing image search (SSRF), potentially exfiltrating sensitive data such as MFA codes, email content, or meeting details to an attacker-controlled external domain.
This rule computes a composite risk score for user authentication events across multiple identity and network providers (Okta, Azure AD, VPNs, etc.). It flags suspicious patterns including impossible travel, credential stuffing indicators (multiple failures followed by success), new or unknown devices, and lateral movement attempts (concurrent access to both VPN and SSO services). Only users meeting a risk score threshold of 40 or higher with at least one successful authentication are reported.
Identifies the loader cementing persistence by creating a scheduled task that executes the RMM payload upon user logon or system start. Specifically looks for 'schtasks.exe' creating a task with a name that is not alphanumeric and a task run command pointing to an executable in the AppData directory.
This rule detects network connections or DNS queries originating from common web browsers (chrome.exe, msedge.exe, chromium.exe) towards domains related to Perplexity AI. Such activity may indicate data exfiltration or the use of AI tools for processing sensitive organizational data via browser-based interfaces.
Detects the presence, file creation, or execution of known proof-of-concept (PoC) scripts, binaries, and directories associated with the exploitation of the libssh2 CVE-2026-55200 vulnerability.
Detects the use of native Windows administration utilities (vssadmin, wbadmin, bcdedit, wmic, powershell) to delete shadow copies, modify boot configurations to disable recovery, or remove backup catalogs, a behavior typically performed by ransomware groups like The Gentlemen to prevent system recovery.
Detects the creation of unrecognized Go-compiled binaries by common developer tools (e.g., node.exe, code.exe) in user-writable or temporary directories, followed shortly by outbound network connections to known C2 infrastructure (e.g., vercel.app, jsonkeeper.com). This behavior is consistent with the 'Contagious Interview' campaign attributed to the Lazarus Group.
