Detects the creation of a PostgreSQL replication slot using an unrecognized or potentially malicious logical decoding plugin. Adversaries may use custom or unauthorized plugins to exfiltrate database contents or intercept replication data streams, bypassing standard monitoring for common plugins like pgoutput or test_decoding.

Detects a multi-stage browser-based web skimming attack. The rule identifies a specific sequence of network activity: a device fetching an obfuscated loader script from 'paste.sh', followed by retrieving payload fragments from the 'Google Sheets Visualization API', and concluding with network interactions with crypto-transaction services 'SwapZone.io' or 'SimpleSwap.io', characteristic of a browser-based wallet-drainer campaign.

This rule detects potential web skimmer activity where a user's browser performs a network connection to known payload delivery hosts (e.g., paste.sh or Google Sheets API) followed by a clipboard modification event on the same device within a one-hour window. This behavior is consistent with malicious scripts attempting to replace copied cryptocurrency wallet addresses with an attacker-controlled address.

This rule detects potential browser-based wallet address substitution attacks by monitoring for a specific sequence of network connections within a single browser process. It looks for connections to cryptocurrency swap platforms (SimpleSwap/SwapZone) closely followed by the retrieval of an external loader script (paste.sh) and a Google Sheets Visualization API payload, which is a known technique for injecting malicious scripts that intercept and modify XHR/fetch responses in the user's browser.

This rule detects potential browser-based manipulation or phishing campaigns where a user visits a known loader script host (paste.sh) and subsequently visits cryptocurrency trading sites (SimpleSwap, SwapZone) within a short time window. This behavior is indicative of an injected script modifying the browser's view of trading sites to display deceptive 'Loyalty Bonus' or discount banners to lure users into transactions.

This rule detects activities related to Tampermonkey (a popular browser extension for userscripts) or interactions with paste.sh, often used for hosting scripts or payloads. The rule monitors both process-level executions and network requests for these indicators, which may be associated with malicious script execution or browser-based credential or session theft.

This rule detects the use of package managers like 'pip' or 'npm' to install specific suspicious software packages or tools often associated with supply chain compromise or malicious library installation (e.g., 'huggingface-cli', 'unused-imports', 'react-codeshift').

Detects package manager processes (npm, pip, python) executing install-related commands followed by the creation or modification of sensitive files (SSH keys, cloud credentials, shell configurations) within a short timeframe. This behavior is indicative of potential supply chain attacks where a malicious package attempts to steal credentials or secrets upon installation.

Detects the installation of software packages in build or CI pipelines where the package was published to its registry between 30 and 90 days prior to being first used in the environment. This pattern is indicative of potential dependency confusion or typosquatting attacks, where adversaries use newly created packages to deliver malicious code.
