Detects high-frequency SCTP ASCONF/ADD-IP chunk packets originating from external networks. This behavior is indicative of a Denial-of-Service (DoS) exploit attempt targeting a vulnerability (CVE-2026-74469) related to DiagSpill transport_count integer wraparound.
Detects high-frequency SCTP ASCONF/ADD-IP chunk packets originating from external networks. This behavior is indicative of a Denial-of-Service (DoS) exploit attempt targeting a vulnerability (CVE-2026-74469) related to DiagSpill transport_count integer wraparound.
Detects high-frequency SCTP ASCONF/ADD-IP chunk packets originating from external networks. This behavior is indicative of a Denial-of-Service (DoS) exploit attempt targeting a vulnerability (CVE-2026-74469) related to DiagSpill transport_count integer wraparound.
This rule detects a high volume of SCTP traffic targeted at internal systems, characterized by mass endpoint creation. This behavior is indicative of an exploit attempt against the 'sctp_diag' kernel component (CVE-2026-74469), which can lead to an out-of-bounds (OOB) write condition, potentially resulting in system instability or denial of service.

Detects outbound HTTP GET requests to a specific C2 domain 'luizestrelhashapr.online' masquerading as CSS file fetches. The request pattern uses a specific path '/google_api/' followed by predefined alphanumeric filenames, consistent with the KREMLIN malware browser extension's C2 polling mechanism.
Detects HTTP requests containing malicious JDBC strings targeting PaperCut NG/MF print management software, which are indicative of attempts to exploit authentication bypass and remote code execution vulnerabilities (CVE-2026-81578, CVE-2026-82078).
Detects Odyssey Stealer malware communicating with a known C2 infrastructure using TLS and performing data exfiltration via HTTP requests to raw-IP destinations using disguised file names such as analytics.gif, pixel.png, and content.js.
Detects network activity associated with the 'ClickFix' campaign, specifically targeting the domain 'mnl.ac' and its associated infrastructure (IPs 149.255.35.135 and 45.74.7.27). The rules monitor for DNS queries, HTTP requests to fetch configuration files (configuration.ps1), and general outbound TCP connections that characterize the staging phase of the ClickFix PowerShell execution chain.
This rule detects potential Device Code Phishing (OAuth 2.0 device authorization) attempts by monitoring HTTP requests to the Microsoft device authorization endpoint (login.microsoftonline.com/common/oauth2/deviceauth) that originate from a suspicious referrer domain ending in .de. This behavior is indicative of an attacker-controlled landing page directing users to authenticate their device.

This behavior is indicative of an attacker-controlled landing page directing users to authenticate their device.
Detects network traffic patterns associated with the Kimsuky threat group utilizing raw.githubusercontent.com as a dead-drop resolver. The rule specifically identifies the retrieval of configuration files (.ini) and victim-specific data files (.dat) containing MachineGuid identifiers, which are characteristic of Kimsuky's command and control (C2) operations.
This rule detects DNS queries directed at known OAST (Out-of-band Application Security Testing) domains, such as 'dnslog.ink' and 'digimg.store', which are commonly used in the 'LucidPawn' framework for verifying external connectivity or exfiltrating data during initial discovery and post-exploitation phases.
Detects network indicators associated with the StealC information stealer, including DNS lookups for identified C2 domains, HTTPS traffic to known C2 endpoints, and suspicious POST requests using multipart/form-data indicative of credential or session data exfiltration.
Detects network indicators associated with the StealC information stealer, including DNS lookups for identified C2 domains, HTTPS traffic to known C2 endpoints, and suspicious POST requests using multipart/form-data indicative of credential or session data exfiltration.
Detects network activity associated with the 'ClickFix' campaign, specifically targeting DNS queries, TLS SNI, HTTP Host headers, and direct IP connections to known malicious infrastructure domains (cdnsuicaches.com, mnl.ac) and exfiltration endpoints (23.227.198.199).
Detects network activity associated with the 'ClickFix' campaign, specifically targeting DNS queries, TLS SNI, HTTP Host headers, and direct IP connections to known malicious infrastructure domains (cdnsuicaches.com, mnl.ac) and exfiltration endpoints (23.227.198.199).

Detects network indicators associated with the StealC information stealer, including DNS lookups for identified C2 domains, HTTPS traffic to known C2 endpoints, and suspicious POST requests using multipart/form-data indicative of credential or session data exfiltration.
Detects network activity associated with the 'ClickFix' campaign, specifically targeting the cdnsuicaches[.]com domain. The rules identify the initial DNS query, the subsequent TLS SNI connection, and the retrieval of malicious JavaScript containing the 'cookie-captcha-complete' overlay signature. This behavior is indicative of a browser-based social engineering attack.
Detects network beaconing and communications associated with the NetSupport Manager remote access tool. The rules monitor for outbound connections to a known actor-controlled IP/domain and identify unauthorized client responses containing a specific license serial number.
