This rule detects potential exploitation of the Oracle PeopleSoft PSEMHUB component vulnerability (CVE-2026-35273). It identifies suspicious POST requests to the PSEMHUB HttpListeningConnector servlet, including obfuscated URL paths, followed by the creation of suspiciously named .jsp or .jspx files in the PSEMHUB.war application directory, which is indicative of a web shell deployment.
Detects an exploitation attempt against PaperCut MF software leveraging SQL injection to deliver a Java bytecode loader (identified by the 'cafebabe' magic bytes) via a POST request.
Detects SQL injection exploitation attempts against MOVEit Transfer targeting the CVE-2023-34362 vulnerability, followed by the deployment and subsequent interaction with the 'human2.aspx' webshell associated with Cl0p ransomware mass-exploitation campaigns.
Detects the creation or modification of SSH authorized_keys or authorized_keys2 files. This is a common persistence technique used to maintain remote access by adding an adversary-controlled public key to a user's configuration, often performed after initial access through exploitation of public-facing services.
Detects SQL injection attempts on the WordPress REST API batch endpoint, specifically targeting the wp_users table to extract user credentials (user_pass and user_login), a technique used by attackers to compromise WordPress installations.
Detects the loading of WPF/XAML-related assemblies (PresentationFramework.dll, System.Xaml.dll, or PresentationCore.dll) by the SharePoint web server process (w3wp.exe). This behavior is highly irregular for typical SharePoint web worker processes and may indicate an exploitation attempt targeting deserialization vulnerabilities leading to remote code execution.
This rule detects potential exploitation attempts targeting the CAPWAP (Control and Provisioning of Wireless Access Points) protocol in FortiOS or FortiSwitchManager. The rule identifies suspicious UDP traffic on port 5246 containing an oversized payload (greater than 1400 bytes), which is characteristic of the exploitation pattern for CVE-2025-25249.
Detects the creation of web shell-consistent files (.jsp, .jspx, .php, .cgi) within sensitive web application directories on Cisco Firepower Management Center (FMC) appliances. This rule is designed to identify potential post-exploitation activity associated with the authentication bypass vulnerability CVE-2026-20079, which has been observed being used by various threat actors to deploy web shells.
Detects VPN/IKE negotiation failures characterized by certificate validation or parsing anomalies on Check Point Security Gateway or Spark firewall devices. These anomalies, when correlated with connections originating from known anonymization infrastructure (such as Tor exit nodes, proxies, or public VPN services), indicate potential exploitation attempts of the CVE-2026-85102 vulnerability, which allows for pre-authentication remote code execution via malformed certificate inputs.
Detects instances where the SQL Server process (sqlservr.exe) initiates command-line utilities such as cmd.exe or powershell.exe, and further identifies suspicious command-line arguments often associated with post-exploitation activity like discovery, credential gathering, or file manipulation.
Identifies NetScaler ADC or Gateway software versions in the inventory that are known to be vulnerable to CVE-2026-88771 and CVE-2026-88772, despite having received the patch for CVE-2026-19490.
This rule monitors network appliance logs (Fortinet, Cisco, Meraki, WatchGuard, Sophos) for patterns associated with known vulnerabilities, including authentication bypass (CVE-2022-40684), SQL injection, path traversal, and command injection attempts within URL parameters. It also flags high-severity IPS/IDS alerts generated by these devices.
This rule identifies suspicious post-exploitation activity where an anomalous or unauthenticated NetScaler VPN session (potentially exploiting CVE-2026-88771 or CVE-2026-88772) is followed by the creation or modification of SSH authorized_keys files or related credential manipulation commands on internal hosts, suggesting an attacker establishing persistence.
This rule performs a retrospective search across device file and network events for indicators of compromise associated with the UNC6240/ShinyHunters actor's activity against PeopleSoft, specifically linked to CVE-2026-35273. It monitors for known malicious file hashes (JSP webshells and executables), connections to known C2 infrastructure, and DNS lookups for specific malicious domains.

It monitors for known malicious file hashes (JSP webshells and executables), connections to known C2 infrastructure, and DNS lookups for specific malicious domains.
Detects incoming web server requests containing suspicious, URL-encoded SQL injection patterns indicative of automated probing or exploitation attempts, such as UNION SELECT, boolean-based injection fragments, and comment sequences.
Detects HTTP requests containing common web exploit patterns (SQLi, XSS, RCE) that exhibit characteristics of automated, mutating payload generation often utilized in AI-assisted fuzzing or vulnerability scanning tools. The rule monitors for encoded, obfuscated, or highly varied payload syntax within URI query strings.
Detects unauthenticated HTTP POST requests to the /prompt endpoint of a ComfyUI instance, which is indicative of an attempt to remotely execute workflows on an exposed instance.
Detects inbound HTTP POST requests to the /generate endpoint of a Hugging Face Text Generation Inference (TGI) server. Such requests indicate attempts to use or interact with the inference API, potentially without authentication, which could lead to unauthorized resource utilization or model interaction if the service is not properly secured.
This rule identifies MikroTik devices running vulnerable versions of RouterOS (specifically those older than 7.24) that are susceptible to CVE-2026-84411. This vulnerability involves an integer underflow in the web management HTTP handling, which can lead to unauthenticated remote code execution or denial of service.
