Detects web access logs matching the specific 'wp_debug_session' parameter used by the ErrTraffic webshell to communicate with compromised servers. This rule identifies HTTP requests containing both 'wp_debug_session=' and 'mode=php' in the URI query string, which are indicators of ErrTraffic webshell activity.
Detects the creation of files on web servers matching known Neo-reGeorg web shell tunnel variants. These files are typically used as backdoors to tunnel traffic and provide persistent access to the server.
Detects execution of MyBB exploitation scripts, specifically targeting the 'mybb_limited_acp_to_admin' PoC, or evidence of a web server process (PHP) spawning suspicious shell or interpreter child processes, suggesting post-exploitation activity on a MyBB platform.
Detects attempts to generate SQL injection payloads by abusing Ollama servers, specifically targeting unauthenticated HTTP POST requests to /api/generate or /api/chat on port 11434. The rule looks for SQL injection indicators and VAPT framework specific strings within the request context, URI, or user agent.
This rule detects instances where the IIS web server process (w3wp.exe) spawns common command-line interpreters such as cmd.exe or powershell.exe. This activity is a classic indicator of a successful web application exploit, potentially leading to remote code execution.
Detects the use of osql.exe or sqlcmd.exe to query database schema information (such as sys.objects, sys.tables, or INFORMATION_SCHEMA) with output redirected to a file. This behavior is flagged when launched from non-standard parent processes, specifically those commonly associated with web shell activity like w3wp.exe, suggesting post-exploitation database discovery.
Detects the GIFTEDCROOK malware performing post-execution cleanup using cmd.exe. The malware utilizes a command-line chain consisting of 'timeout' and 'del' to remove staged payloads from C:\ProgramData and persistence shortcuts (.lnk files) from the user's Startup folder after a delay.
Detects web access logs matching the specific 'wp_debug_session' parameter used by the ErrTraffic webshell to communicate with compromised servers. This rule identifies HTTP requests containing both 'wp_debug_session=' and 'mode=php' in the URI query, which are indicators of the ErrTraffic webshell activity.
This rule monitors for suspicious activity related to Microsoft Exchange server exploitation and persistence techniques. It detects three distinct behaviors: the creation of web shell files (.aspx, .ashx, .asmx) within Exchange directories (OWA/ECP), the spawning of shell processes (cmd, powershell) by the w3wp.exe web server process, and DLL sideloading occurring through identified signed binaries (dfsvc.exe, rasautou.exe) outside of standard system directories.
This rule monitors for suspicious activity related to Microsoft Exchange server exploitation and persistence techniques. It detects three distinct behaviors: the creation of web shell files (.aspx, .ashx, .asmx) within Exchange directories (OWA/ECP), the spawning of shell processes (cmd, powershell) by the w3wp.exe web server process, and DLL sideloading occurring through identified signed binaries (dfsvc.exe, rasautou.exe) outside of standard system directories.
Detects anomalous web session traffic that proxies enterprise authorization endpoints (e.g., oauth, saml, login) while simultaneously interacting with session-related cookies. This behavior is indicative of an Adversary-in-the-Middle (AiTM) proxy setup used to capture session tokens and bypass authentication.
This rule detects when the Internet Information Services (IIS) worker process (w3wp.exe) accesses sensitive files such as 'web.config', 'applicationHost.config', or 'win.ini'. Unauthorized access to these files by the IIS process can be an indicator of a web shell or other malicious post-exploitation activity attempting to steal credentials, application secrets, or system configuration information.
This rule detects outgoing network connections from the IIS worker process (w3wp.exe) to public-facing URLs that match common Microsoft Office WOPI (Web Application Open Platform Interface) request patterns, but are directed to domains other than trusted Microsoft-affiliated infrastructure. This behavior can be indicative of a Server-Side Request Forgery (SSRF) attempt, where an attacker tries to coerce the server into making unauthorized requests to external resources.
Detects the decoded execution of bash/sh reverse shells initiated from processes like node.exe or python.exe, which is indicative of the Void Dokkaebi threat actor's tactics. The rule specifically looks for command lines containing 'echo' with base64 encoded strings, followed by 'base64 -d' and then 'sh' or 'bash' for execution.
Detects attempts to upload files to the SharePoint master page gallery using a POST request. This activity can be indicative of an attacker attempting to establish persistence or deface the SharePoint site by modifying its core components. The rule specifically looks for requests to '_layouts/15/Upload.aspx' or '_layouts/Upload.aspx' with 'RootFolder' and 'List' parameters containing '_catalogs/masterpage' or directory traversal sequences ('../').
Detects MQTT publish-subscribe protocol used as covert C2 channel
Detects web shell deployment and subsequent execution activities associated with the StrikeShark threat. The detection covers two primary behaviors: 1) IIS worker processes (w3wp.exe or UMWorkerProcess.exe) spawning suspicious child processes (cmd.exe, powershell.exe, etc.) indicating shell command execution, and 2) IIS worker processes creating potential web shell files (.aspx, .ashx, .asmx, .svc) within sensitive web root directories, including Exchange and SharePoint paths.
Detects network connections attempting to exfiltrate data via Discord webhooks. This rule specifically looks for POST requests to the Discord API webhook endpoint.
Detects the Miasma worm utilizing the Bun runtime to execute malicious payloads. The detection looks for Bun processes executing scripts from /tmp/, specifically patterns associated with the Miasma worm, or processes matching the known malicious Bun runtime hash.
Detects a sequence of suspicious activities characteristic of an SSH-based worm. The rule correlates non-standard processes reading SSH private keys, the presence of known cryptominer components (lambsys, procq, isp.sh), and subsequent SSH network fan-out activity from the same host, indicating lateral movement.
Detects web server processes (IIS/Nginx) spawning native Windows or Linux shells (cmd.exe, sh, bash), immediately followed by reconnaissance or download tool execution (whoami.exe, ping.exe, certutil.exe, curl, wget) within a 2-minute window. This pattern is indicative of a web shell being used for initial system compromise and subsequent information gathering or tool deployment.
