Detects repeated suspicious network requests, including non-standard HTTP methods and URI structures, as well as TLS SNI anomalies, targeting the internal sales portal 'agent.3bb.co.th'. The rule triggers when a threshold of 20 requests within a 60-second window is reached from a single source, indicating likely automated reconnaissance or vulnerability scanning activity.
This rule detects anomalous access patterns on a specific IIS host (agent.3bb.co.th) by comparing recent traffic against a 30-day historical baseline. It identifies requests from accounts or source IPs not seen in the baseline, activity occurring during off-hours, or traffic from external sources. The rule further filters for high-volume or high-path diversity requests, which are indicative of automated reconnaissance or potential brute-force activity against the web application.
Detects high-frequency access to 'about' pages from a single IP address, indicative of potential reconnaissance or information gathering on an organization's public-facing infrastructure. The rule filters out common search engine crawlers and triggers only when a significant number of distinct pages are requested within a short timeframe.

The rule filters out common search engine crawlers and triggers only when a significant number of distinct pages are requested within a short timeframe.
This rule monitors web server logs (IIS, W3C, and Azure Application Gateway) for incoming traffic that matches known malicious or automated vulnerability scanners, as well as requests for common system fingerprinting paths (such as /server-status or /.git/config). The rule aggregates these hits by source IP address to identify potential active reconnaissance or vulnerability scanning attempts.

The rule filters out common search engine crawlers and triggers only when a significant number of distinct pages are requested within a short timeframe.
This rule monitors for active reconnaissance or scanning behavior by detecting a single source IP interacting with a high number of distinct ports/hosts within a short time frame (NetworkScan) or accessing a high number of distinct URI paths/404 errors (WebContentScan).
Detects potential web reconnaissance or scanning activity against Microsoft IIS servers. The rule identifies suspicious behavior by monitoring for high frequencies of distinct URI requests, excessive 404 Not Found status codes indicative of path brute-forcing, and the presence of known security scanning user-agents.
Detects repeated suspicious network requests, including non-standard HTTP methods and URI structures, as well as TLS SNI anomalies, targeting the internal sales portal 'agent.3bb.co.th'.

Detects repeated suspicious network requests, including non-standard HTTP methods and URI structures, as well as TLS SNI anomalies, targeting the internal sales portal 'agent.3bb.co.th'. The rule triggers when a threshold of 20 requests within a 60-second window is reached from a single source, indicating likely automated reconnaissance or vulnerability scanning activity.
Detects anomalous GitHub activity where a single actor interacts with 20 or more unique repositories within a 24-hour period. This behavior is indicative of potential repository scraping, unauthorized data harvesting, or mass configuration changes associated with reconnaissance or exfiltration activity.
Detects automated reconnaissance and enumeration of sensitive web application paths (admin, config, environment files, etc.) from a single source IP. The rule identifies high-frequency request patterns that target specific non-public surface areas while excluding known search engine crawlers and monitoring bots.
Detects anomalous DNS activity characterized by either unauthorized DNS zone transfer (AXFR/IXFR) requests or aggressive subdomain enumeration patterns from external IP addresses. This rule monitors for high volumes of non-standard DNS queries or distinct subdomain lookups within a 15-minute window, which are common precursors to reconnaissance activities.
Detects high-frequency, automated requests to product and catalog pages within a short time window, characteristic of web scraping or catalog harvesting often used to feed fake-shop networks or build clone sites.

Detects high-frequency, automated requests to product and catalog pages within a short time window, characteristic of web scraping or catalog harvesting often used to feed fake-shop networks or build clone sites.
This rule detects potential automated web scraping activity by identifying high-volume, repetitive network requests directed towards domains identified as government (.gov) or military (.mil). It correlates these network patterns with the execution of common browser automation frameworks (e.g., Puppeteer, Playwright) or headless browsers, indicating a likely coordinated scraping operation or bot activity.
Detects a host performing high-volume outbound network scanning (connecting to 10 or more distinct public IP addresses within 15 minutes) followed by the execution of an executable file created in common suspicious directories (AppData, Temp, Downloads, or Users/Public) within a short window (10 minutes after the scan). This pattern is indicative of a compromised host scanning for lateral movement opportunities or propagation targets, followed by the deployment of malicious tooling.
