Detects potential web shell installation via WordPress administrative panels. The rule identifies a WordPress administrator session executing a theme installation request triggered by an external (off-site) referer, followed shortly thereafter by the creation of new PHP files within the WordPress themes directory. This pattern is often indicative of an attacker leveraging a compromised admin session to upload a backdoor.
Detects successful POST requests to the WordPress admin-ajax.php endpoint utilizing the 'wwlc_file_upload_handler' action with an empty referrer header. This pattern is characteristic of attackers attempting to upload malicious files via vulnerable WordPress plugins to establish web shell persistence.

Detects anomalous access to WSO2 API Manager Store and Publisher endpoints involving the retrieval of sensitive information like consumer keys and secrets. The rule specifically targets requests authenticated with JWTs that exhibit headers indicative of 'alg=none' or other unsupported/forged algorithm patterns, often associated with CVE-2026-5430 exploitation attempts. The rule uses statistical baseline monitoring to identify volume spikes in requests to these sensitive paths.

Detects incoming HTTP requests to the WSO2 admin API endpoint that utilize a JSON Web Token (JWT) with the 'alg=none' algorithm, indicating an attempt to bypass authentication via JWT token forgery (CVE-2026-5430).
Detects incoming HTTP requests to the WSO2 admin API endpoint that utilize a JSON Web Token (JWT) with the 'alg=none' algorithm, indicating an attempt to bypass authentication via JWT token forgery (CVE-2026-5430).
Detects attempts to exploit a vulnerability in WSO2 API Manager and Traffic Manager that allows for authentication bypass by utilizing a malformed JWT with the 'alg=none' header. Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.

Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.
Detects high-volume, sequential HTTP requests directed at sensitive PaperCut NG/MF web interfaces from a single source IP address within a one-hour window. The high frequency of unique target access suggests automated scanning or exploitation attempts (consistent with CVE-2026-81578/CVE-2026-82078) typical of AI-driven or scripted attack campaigns.
This rule detects HTTP GET requests to a specific URI path ('/wp-content/uploads/init/') on the domain 'wasmer.app', which is associated with Kimsuky (APT43) C2 beaconing activity. The presence of a token parameter in the URI and the structure of the request indicates an established connection for command and control purposes.
Detects HTTP POST requests to the Dropbox API endpoint (/2/files/upload) that appear to be unauthorized file uploads, specifically identifying patterns associated with the Kimsuky threat group. The rule triggers on both the presence of suspicious directory naming conventions (_lns/) in the Dropbox-API-Arg header and the use of hardcoded Authorization bearer tokens, both characteristic of Kimsuky's data exfiltration techniques.

Detects specific malformed HTTP request patterns associated with the Casbaneiro (Metamorfo) banking trojan. The rules identify suspicious beaconing attempts, including specific URI structures ('/$p', '/$or?u=') and malformed headers (missing Host header combined with specific Content-Length anomalies).

Detects network communication associated with the Casbaneiro (Metamorfo) banking trojan, specifically identifying DNS queries, TLS SNI headers, HTTP Host headers, and direct IP connections to known malicious C2 infrastructure.
Detects network traffic (DNS queries, HTTP requests, and TLS SNI) directed towards the domain 'htlwub00klocate.blogspot.com', which is associated with adversary staging activity.
This rule detects potential command and control (C2) activity associated with the Koktevrat malware, specifically looking for WebSocket handshake requests (HTTP GET with 'Upgrade' header) to domain names that follow a generated pattern (8-27 alphanumeric characters ending in .icu or .cfd).
