7,139 detections

Detects a sequence of suspicious behaviors on a single host within a 1-hour window, indicative of an adversary establishing a foothold and preparing for malicious activity. The pattern involves: 1) System architecture discovery, 2) Downloading files from an external IP address, 3) Changing permissions of files in temporary directories (e.g., /tmp, /var/tmp, /dev/shm), and 4) Executing files directly from those same temporary directories.

This rule detects the creation of a .groovy file within a plugin directory related to JFrog Artifactory, followed by the execution of suspicious child processes (e.g., shell, curl, wget) by the Artifactory process within a short timeframe. This behavior is indicative of an attacker attempting to achieve remote code execution by deploying a malicious plugin.

103
Detects reconnaissance commands (e.g., file listing, directory enumeration) executed as child processes of the JFrog Artifactory service. This behavior is often associated with the exploitation of Artifactory plugins or misconfigured endpoints that allow arbitrary code execution, enabling an attacker to perform discovery actions.

Detects successful authentication attempts to a LiteLLM proxy instance using the hardcoded default master key 'sk-1234'. This activity indicates potential exploitation of misconfigured instances where default credentials remain unchanged.

Detects instances where LiteLLM, or related Python application processes (uvicorn, python), spawn a shell or command-line utility (bash, sh, id) under the root user account. This behavior is indicative of potential container breakout, application exploitation, or privilege escalation attempts originating from a web-accessible service.

Detects credential harvesting behavior originating from known malicious RubyGems packages (pwnp999, exfiltestwand3, hacksvn1778554764) observed in RubyDoc.info build environments. The rule monitors process execution and file access activity involving these packages where the command line or file path includes patterns associated with credential theft (e.g., 'api_key', 'Authorization'), scoped to Ruby-related tooling such as 'ruby', 'gem', or 'bundle'.

Detects the registration of browser service workers from suspicious sources. Service workers can be used to maintain persistence, intercept network requests, or perform browser-based man-in-the-middle attacks. This rule specifically alerts on service workers initialized with 'blob:' URIs or those originating from the suspicious 'cdn.bloom.io' domain.

105
Detects Git checkout operations involving specific SHA hash arguments that occur in conjunction with potential ambiguous refname errors, or are initiated by processes commonly used for AI-assisted coding (e.g., Copilot, Claude). This rule monitors for potentially malicious source code repository manipulation or automated branch hijacking attempts, often seen in supply chain or development environment attacks.

This rule detects processes accessing sensitive credential, configuration, or environment files typically stored in locations like .aws, .ssh, .kube, or application user directories. It alerts when a non-standard or unexpected process touches multiple sensitive folders, or when specific suspicious process names or known malicious tools (such as 'NeedleStealer') are observed interacting with these files. This is indicative of potential credential harvesting or reconnaissance activities.

Detects a 'git checkout' command targeting a specific commit SHA that is not followed within five minutes by a 'git rev-parse HEAD' integrity check. This behavior, known as 'Plugin4Shell', involves an attacker replacing a pinned commit with a malicious branch of the same name, potentially leading to unauthorized code execution if verification steps are absent.

Detects automated searching (via grep, findstr, or select-string) for sensitive strings (e.g., API keys, private keys, wallet data) across multiple occurrences on a single host, or the creation of suspicious sensitive files (e.g., .env, credentials, wallet.dat) on devices where such automated sweeping activity has been observed. This pattern indicates an adversary staging data for exfiltration.

Detects unauthorized access and data retrieval attempts from a MinIO object storage instance using default administration credentials (minioadmin:minioadmin). The rule monitors both command-line execution of MinIO client (mc) operations and network connections to MinIO service ports (9000/9001) that involve the use of the default credential pair.

Detects lateral movement activity where a host identified as running the Langflow framework attempts to connect to internal MySQL (3306) or Nacos (8848) services while utilizing root credentials, potentially indicating an attacker pivoting from a compromised application server.

Detects the execution of PostgreSQL dump utilities (pg_dump, pg_dumpall) initiated directly by application-level processes like Langflow or Python, rather than through standard system-level task schedulers. This behavior is indicative of unauthorized data collection or staging of database contents by an application process.
