Detects network activity associated with the FlowerStorm/Storm-1167 phishing campaign. The rule monitors for credential exfiltration to a specific malicious URI (e.g., /google.php) containing login parameters, as well as the delivery of spoofed Microsoft sign-in pages from the associated phishing infrastructure.

Detects HTTP POST requests directed to the URI path '/api/credentials' over the non-standard TCP port 8133, which is indicative of AMOS (Atomic macOS) Stealer exfiltrating stolen credentials to a C2 server.

Detects network activity indicating interaction with known Adversary-in-the-Middle (AiTM) phishing infrastructure. This includes direct outbound connections to specific suspicious IP addresses and the identification of proxied Microsoft 365 OAuth authorization flows redirected to non-Microsoft hosts.
Detects outbound network connections (HTTP/TLS) from internal hosts to a known malicious IP address associated with Adversary-in-the-Middle (AiTM) phishing infrastructure, specifically targeting Microsoft 365 credential and session cookie theft.
Detects outbound network connections (HTTP/TLS) from internal hosts to a known malicious IP address associated with Adversary-in-the-Middle (AiTM) phishing infrastructure, specifically targeting Microsoft 365 credential and session cookie theft.
Detects HTTP POST requests containing potential credential exfiltration indicators, specifically targeting the '/google.php' endpoint with 'do=login&', 'user=', and 'pass=' parameters. This pattern is associated with FlowerStorm (Storm-1167) AiTM phishing kits.
Detects a multi-stage phishing attack targeting cryptocurrency users, specifically Ledger wallet holders. The detection identifies an initial request to a Vercel-hosted domain for a BIP-39 wordlist (a common recovery phrase standard) followed by a POST request to a similar Vercel-hosted endpoint, suggesting the exfiltration of a secret recovery phrase.

Detects network activity associated with Mirage2FA Adversary-in-the-Middle (AiTM) phishing infrastructure. The rules monitor for HTTP responses containing specific spoofed Microsoft 365 sign-in page content, DNS resolutions for known proxy-associated domain suffixes, and client requests fetching malicious loader scripts from suspected AiTM hosting infrastructure.
Detects network traffic indicating a potential adversary-in-the-middle (AiTM) phishing proxy attempting to relay authentication requests to the legitimate Microsoft login service. The rule triggers when an external host acts as a reverse proxy for login.microsoftonline.com endpoints without being the legitimate Microsoft service itself.
This rule detects potential exfiltration of sensitive files, specifically 'cert.pem' and 'private.key', via HTTP POST requests to the '/api/adbk/upload' endpoint. This pattern is characteristic of the RatHat malware attempting to exfiltrate device credentials to a Command and Control (C2) server.
This rule detects potential credential stuffing attempts against a Fortinet FortiGate SSL VPN portal. It triggers when an external source performs multiple HTTP POST requests to the /remote/login endpoint within a short period, accompanied by the FortiGate-specific header, which is indicative of automated brute-force or credential stuffing activity associated with the 'FortiBleed' campaign pattern.
This rule monitors and alerts on network traffic (TCP/TLS/HTTP) directed toward a known malicious IP address associated with an Adversary-in-the-Middle (AiTM) phishing infrastructure, categorized under the PREY-0058 designation.
This rule detects HTTP requests to the Microsoft device login endpoint (/devicelogin) that originate from a non-Microsoft referrer domain. This behavior is highly indicative of Adversary-in-the-Middle (AiTM) phishing attacks targeting OAuth device code flows, where a malicious proxy site redirects users to the legitimate Microsoft login page while attempting to capture session tokens.
This rule detects network traffic indicative of an Adversary-in-the-Middle (AiTM) phishing attack targeting Microsoft 365. The rule identifies HTTP response bodies containing 'login.microsoftonline.com' and 'Enter Password' being served from a web server identified as 'openresty'. This configuration is common for phishing kits that proxy traffic between the victim and the legitimate service to harvest credentials and session cookies.
This rule detects HTTP requests to the Microsoft device login endpoint (/devicelogin) that originate from a non-Microsoft referrer domain. This behavior is highly indicative of Adversary-in-the-Middle (AiTM) phishing attacks targeting OAuth device code flows, where a malicious proxy site redirects users to the legitimate Microsoft login page while attempting to capture session tokens.
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.
