Detects network connections to dedicated IP addresses previously used to host Evilginx phishing proxies. While the threat actor has reportedly shifted to using Cloudflare, these IPs represent past infrastructure and should be monitored for potential reuse.
Detects attempts to exploit a path traversal vulnerability (CVE-2025-64446) in FortiWeb. Attackers send a crafted POST request to create a new administrative user by targeting a specific URI and including keywords in the request body indicative of new admin creation.
Detects the unique User-Agent string "A WinHTTP Example Program/1.0" used by the MuddyViper backdoor for C2 communications, as reported in the MuddyWater campaign.
Detects HTTP requests targeting the Oracle Identity Manager REST API that contain known authentication bypass suffixes, such as `?WSDL` or `;.wadl`. This indicates an attempt to exploit the initial authentication bypass stage of the CVE-2025-61757 exploit chain.
Detects unique strings associated with the JSKit iOS exploitation framework in network traffic. This framework is used by multiple threat actors, including the commercial surveillance vendor Intellexa, to deliver spyware like Predator.
Detects network connections originating from notepad.exe to suspicious domains or IP addresses. This is a high-fidelity indicator of compromise associated with the SERPENTINE#CLOUD campaign, where a malicious payload is injected into the notepad.exe process for C2 communications.
Detects potential Command and Control (C2) communication from the AK47C2 backdoor over HTTP. The backdoor sends a hex-encoded JSON payload via HTTP POST requests. This rule specifically looks for HTTP POST requests with a request body longer than 100 characters that consists entirely of hexadecimal characters, indicative of the AK47C2 communication pattern.
This search detects network connections to a specific webhook.site URL known to be used by the Shai-Hulud 2.0 worm for data exfiltration.
This rule detects web requests targeting SharePoint endpoints associated with the ToolShell exploit chain (CVE-2025-49704, CVE-2025-49706, CVE-2025-53770, CVE-2025-53771). This activity is linked to the threat actor CL-CRI-1040 (also known as Storm-2603). The rule specifically looks for requests to "/_layouts/15/ToolPane.aspx" or "/_layouts/15/SignOut.aspx" that also contain suspicious strings indicative of command execution or file manipulation attempts, such as "cmd.exe", "powershell", "whoami", "ipconfig", "systeminfo", "&cmd=", or "&file=".
Detects HTTP requests attempting to exploit several IoT device vulnerabilities leveraged by the ShadowV2 botnet to spread. This rule looks for specific URI paths and command injection payloads associated with known CVEs.
Detects exploitation attempts targeting a code injection vulnerability in XWiki's SolrSearch macro (CVE-2025-24893). Attackers can inject malicious Groovy code through specially crafted requests to the SolrSearch endpoint, leading to unauthenticated remote code execution.
Detects when multiple distinct domains, where at least one is known malicious, share the same HTTP body SHA1 hash or favicon MD5 hash. This pattern is indicative of threat actor infrastructure reuse and templating, as described in analysis of campaigns like LaundryBear and FreeDrain.
Detects the RedTail cryptominer targeting exposed Docker APIs by looking for specific HTTP request patterns, including the 'libredtail-http' user agent and 'docker.selfrep' parameter in the request body.
Detects outbound HTTP GET requests consistent with Lumma Stealer's browser fingerprinting activity. This activity involves contacting a C2 endpoint at '/api/set_agent' with specific URL parameters ('id', 'token', 'description') to register the victim and gather system information.
Detects FileFix campaigns that use clipboard manipulation functions in web pages to deliver malicious PowerShell commands. These campaigns often trick users into copying and executing payloads, sometimes involving steganography with image files.
The query below correlates device inventory, IP assignment and network events to identify internal endpoints attempting to connect to routers — including whether they succeeded and via Web or Application access. Attack traffic often aligns with failed HTTP/HTTPS attempts or unknown device names.
PwnDrp Access
Sigma
Detects downloads from PwnDrp web servers developed for red team testing and most likely also used for criminal activity
Detects attempts to exploit the Triofox authentication bypass vulnerability (CVE-2025-12480) by sending a request with a 'localhost' Host header from an external IP address to access administrative pages. This allows an attacker to create a new administrative account.
Detects network traffic to Large Language Model (LLM) providers that have not implemented mitigations for the Whisper Leak side-channel attack. Communication with these providers is more susceptible to topic inference attacks.
Detects suspicious user agent strings used by crypto miners in proxy logs
Hack Tool User Agent
Sigma
Detects suspicious user agent strings user by hack tools in proxy logs
