The analytic detects potential exploitation of the CrushFTP authentication bypass vulnerability (CVE-2025-31161). This detection identifies suspicious command execution patterns associated with exploitation of this vulnerability, such as executing mesch.exe with specific arguments like b64exec or fullinstall. This activity is indicative of an attacker exploiting CVE-2025-31161 to gain unauthorized access to the CrushFTP server and perform post-exploitation activities.
The following analytic detects attempts to exploit the CVE-2024-27198 vulnerability in JetBrains TeamCity on-premises servers, which allows attackers to bypass authentication mechanisms. It leverages Suricata HTTP traffic logs to identify suspicious POST requests to the `/app/rest/users` and `/app/rest/users/id:1/tokens` endpoints. This activity is significant because it can lead to unauthorized administrative access, enabling attackers to gain full control over the TeamCity server, including projects, builds, agents, and artifacts. If confirmed malicious, this could result in severe security breaches and compromise the integrity of the development environment.
Detects potential prompt injection or jailbreak attempts against Ollama API endpoints by identifying requests with abnormally long response times. Attackers often craft complex, layered prompts designed to bypass AI safety controls, which typically result in extended processing times as the model attempts to parse and respond to these malicious inputs. This detection monitors /api/generate and /api/chat endpoints for requests exceeding 30 seconds, which may indicate sophisticated jailbreak techniques, multi-stage prompt injections, or attempts to extract sensitive information from the model.
Detects potential command injection attempts in the body of HTTP POST requests. Attackers, such as those operating the RondoDoX botnet, exploit unsanitized input fields in web interfaces of SOHO routers, IoT devices, and other applications to execute arbitrary commands. This rule looks for common command-line tools and shell characters within the POST body, particularly in requests targeting parameters known to be vulnerable.
This analytic detects instances where web or application server processes (such as Java, Tomcat, Apache, Nginx, Node, Caddy, IIS, PHP) spawn a Linux or Windows shell. This activity is highly indicative of successful exploitation, potentially related to vulnerabilities like Log4Shell (CVE-2021-44228) or Spring4Shell (CVE-2022-22965), leading to unauthorized command execution, privilege escalation, or persistent access. The detection leverages Endpoint Detection and Response (EDR) telemetry, focusing on parent-child process relationships and process names.
This analytic identifies instances where `java.exe` or `tomcat.exe` spawns a Windows shell, such as `cmd.exe` or `powershell.exe`. This activity is significant as it may indicate exploitation attempts, such as those related to CVE-2021-44228 (Log4Shell) or CVE-2022-47966. If confirmed malicious, attackers could execute arbitrary commands, potentially leading to system compromise, data exfiltration, or further lateral movement within the network.
Detects Ollama server errors and failures during model loading operations that may indicate malicious model injection, path traversal attempts, or exploitation of model loading mechanisms to achieve remote code execution. Adversaries may attempt to load specially crafted malicious models or exploit vulnerabilities in the model loading process to execute arbitrary code on the server. This detection monitors error messages and failure patterns that could signal attempts to abuse model loading functionality for malicious purposes.
The analytic detects instances where Java or Tomcat processes spawn a Linux shell. This activity may indicate exploitation attempts, such as those related to CVE-2021-44228 (Log4Shell). This detection leverages Endpoint Detection and Response (EDR) telemetry, focusing on process names and parent-child process relationships. This activity is significant as it can signify a compromised Java application, potentially leading to unauthorized shell access. If confirmed malicious, attackers could execute arbitrary commands, escalate privileges, or maintain persistent access, posing a severe threat to the environment.
Detects the initial access attempt for the Oracle E-Business Suite vulnerability CVE-2025-61882. This involves a crafted POST request to the UiServlet component containing a malicious XML payload.
Detects a potential Oracle E-Business Suite (EBS) authentication bypass attempt, associated with the exploitation of CVE-2025-61882. This activity involves an HTTP POST request to the '/OA_HTML/SyncServlet' endpoint, which is the initial step observed in the exploit chain used by threat actors like GRACEFUL SPIDER.
Detects a variety of HTTP exploitation attempts associated with the RondoDox botnet campaign. This campaign uses a 'shotgun' approach, targeting numerous vulnerabilities in internet-facing devices like routers, DVRs, and web servers.
Detects attempts to exploit a SQL injection vulnerability (CVE-2025-57819) in FreePBX via a malicious GET request to '/admin/ajax.php'. Attackers leverage this to achieve remote code execution by inserting a malicious cron job.
Detects potential exploitation attempts against FortiWeb CVE-2025-52970. The detection looks for individual HTTP GET requests to a specific API endpoint with a crafted APSCOOKIE_FWEB cookie containing 'Era=9'. The rule enriches alerts with information about known malicious IPs without strictly filtering on them.
Detects suspicious child processes spawned by the GoAnywhere MFT Tomcat service. This behavior is consistent with post-exploitation activity following a successful remote code execution exploit of CVE-2025-10035, as observed in campaigns by the threat actor Storm-1175.
Detects CVE-2024-2389 detected on April 23 on Progress Flowmon. This rule detecting access to the vulnerable function parameters in specific endpoin (/service.pdfs/confluence). Attacker can be use vulnerable file and pluginPath variables directly requesting them. Howewer, to able to use those two variables lang must set to any value.
Detects suspicious file writes to the root directory of web applications, particularly Apache web servers or Tomcat servers.
This may indicate an attempt to deploy malicious files such as web shells or other unauthorized scripts.
This may indicate an attempt to deploy malicious files such as web shells or other unauthorized scripts.
Detects attempts to exploit multiple vulnerabilities (CVE-2025-52905, CVE-2025-52906, CVE-2025-52907) in TOTOLINK X6000R routers. Attackers can leverage argument injection, unauthenticated command injection, and security bypasses through the '/cgi-bin/cstecgi.cgi' endpoint to achieve remote code execution or denial of service.
Detects exploitation attempts against common network edge devices (Cisco, Ivanti, Palo Alto) associated with Salt Typhoon's TTPs for initial access.
Detects attempts to bypass authentication in Fortra GoAnywhere MFT by exploiting a vulnerability (CVE-2025-10035). This is achieved by sending a crafted GET request to the Unlicensed.xhtml endpoint to trigger an exception and obtain a valid license request token, which is a prerequisite for further exploitation.
KQL Query from file: Endpoint SMB Exposed on Public Internet
Detects BadIIS malware variants associated with the 'Operation Rewrite' campaign (CL-UNK-1037). This rule identifies the native IIS module, PHP backdoors, and other related components used for SEO poisoning.
