Detects network activity (DNS queries, TLS SNI, and HTTP requests) associated with identified 'ShipmentsFree' scam domains. These domains are typically used in phishing or credential harvesting campaigns to trick users into visiting fake account or tracking pages.

Detects DNS queries, HTTP requests, and TLS SNI traffic directed towards the domain 'cloudflare-check.net', which is associated with 'ClickFix' social engineering campaigns used to deceive users into executing malicious code.
This rule detects DNS queries, TLS Server Name Indication (SNI) lookups, and HTTP Host header requests directed towards a list of known domains associated with 'Exvicy' malicious activities (lure domains).
Detects DNS, TLS SNI, and HTTP Host header requests to known phishing domains mimicking Passkey or Single Sign-On (SSO) authentication services. These domains attempt to deceive users into providing credentials or performing unauthorized authentication actions.
Detects DNS queries and HTTP Host header traffic to known SilverFox malware impersonation domains. These domains utilize .com.cn TLDs and typosquatting techniques to masquerade as legitimate software or service providers.
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).
This query provides high-fidelity, post-exploitation hunting for CVE-2026-69730 by catching unauthorized child processes spawned from the Windows DNS Server engine (dns.exe).
Because dns.exe runs natively as NT AUTHORITY\SYSTEM and almost never executes external binaries during normal operations, filtering out known OS noise (conhost.exe and werfault.exe) flags potential RCE breakouts and privilege escalation with near-zero false positives.

Detects DNS queries, HTTP host headers, and TLS SNI traffic associated with the SilverFox relay and dispatch infrastructure. These indicators are commonly used by the SilverFox malware for command and control (C2) communications.
Detects DNS queries and TLS SNI traffic directed towards known phishing domains associated with credential harvesting campaigns (specifically those attributed to Storm-3121/Storm-3032). These domains are used to lure users into providing credentials under the guise of SSO or passkey setup.
This rule detects DNS queries for suspicious domains that mimic MFA or passkey registration portals. Such domains are often used in phishing campaigns to lure users into registering their credentials or security tokens on adversary-controlled infrastructure.
Detects network communication associated with the Casbaneiro (Metamorfo) banking trojan, specifically identifying DNS queries, TLS SNI headers, HTTP Host headers, and direct IP connections to known malicious C2 infrastructure.
Detects network communication associated with the Casbaneiro (Metamorfo) banking trojan, specifically identifying DNS queries, TLS SNI headers, HTTP Host headers, and direct IP connections to known malicious C2 infrastructure.
Detects DNS queries, TLS SNI headers, and HTTP host headers associated with identified C2 infrastructure for NetSupport Manager malware, specifically domains themed around 'GTA6'. These indicators are used by attackers for command and control communication.
Detects network traffic (DNS queries, TLS SNI, and HTTP Host headers) targeting the domain 'expresshost.cloud', which is identified as hosting VPS infrastructure commonly used for scanning and malicious activities.
Detects periodic beaconing and C2 communication patterns associated with the RapidRust Golang RAT, attributed to the APT36 (Transparent Tribe) threat group. The rule monitors for specific DNS queries to typosquatted domains, TLS SNI mismatches, and specific HTTP API polling activities commonly used by this malware for C2 tasking.
Detection of suspicious DNS queries associated with Adversary-in-the-Middle (AiTM) phishing infrastructure. The rules monitor for suspicious subdomains and TLD patterns targeting Microsoft login services, as well as behavioral sequences involving initial Google Ads traffic redirection followed by rapid lookups of suspected malicious or newly registered domains and external geolocation services.
Detects network traffic (DNS, TLS SNI, and HTTP Host headers) attempting to communicate with infrastructure associated with the EvilTokens Phishing-as-a-Service (PhaaS) platform. This activity is indicative of credential harvesting or adversary-in-the-middle (AiTM) attacks.
Detects DNS lookups and subsequent HTTP requests to known domains associated with the Exvicy pop-under/loader malware. These domains are identified as malicious lures often used to initiate payload downloads.
Detects network communication associated with the Casbaneiro (Metamorfo) banking trojan, specifically identifying DNS queries, TLS SNI headers, HTTP Host headers, and direct IP connections to known malicious C2 infrastructure.
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.
