Detects network traffic potentially associated with a scraper botnet variant that uses the "Hello-World/1.0" user-agent string and performs GET requests. This activity is indicative of reconnaissance or data scraping.

This power query is to detect NPM package is downloaded by the user, using the SentinelOne Singularity Power query.
Detects indicators of compromise (IOCs) and suspicious OAuth consent activity
linked to the Tycoon/ODx phishing kits. These campaigns impersonate Microsoft
OAuth apps to bypass MFA and harvest Microsoft 365 credentials.

Detects ERMAC V3.0 C2/panel/builder traffic using backend API routes, auth artifacts, exfil paths, injects directory indicators, and unique strings from the source leak. Emphasizes multi-indicator matches in the same event for high confidence.
This rule detects suspicious ad click traffic that routes through Google Ad Services It specifically looks for URLs containing Google Click Identifier (gclid), an ad URL, and a placement ID, while excluding legitimate ad routing services. This could indicate ad fraud or malvertising.
Most but not all clicks on Google ads are routed this way.

Detects HTTP GET requests originating from the 'Hello-World/1.0' user agent to common web ports.
The analytic identifies allowed network traffic to The Onion Router (TOR), an anonymity network often exploited for malicious activities. It leverages data from Next Generation Firewalls to detect traffic where the application is TOR and the action is allowed. This activity is significant as TOR can be used to bypass conventional monitoring, facilitating hacking, data breaches, and illicit content dissemination. If confirmed malicious, this could lead to unauthorized access, data exfiltration, and severe compliance violations, compromising the integrity and security of the network.
Detects the download of a Java Archive (.jar) file from common file-sharing services like Dropbox or MediaFire. This behavior is associated with sophisticated email campaigns where attackers use PDF attachments with embedded links to trick users into downloading and executing Remote Access Trojans (RATs).
Detects network connections to domains matching patterns commonly used by the Scattered Spider threat group for phishing campaigns.
The group often registers domains that mimic legitimate corporate services by appending suffixes like "-sso", "-servicedesk", "-okta", "-vpn", or "-helpdesk" to a target's name (e.g., victim-sso.com).

SPL Query from file: Beavertail Exfiltration over TCP
'It is reccomended that these Categories shoud be blocked by policies because they provide harmful/malicious content..'
'Detects suspicious user agent strings used by crypto miners in proxy logs.'
'This detection will identify network requests in HTTP proxy data that contains Base64 encoded usernames from machines in the DeviceEvents table.
This technique was seen usee by POLONIUM in their RunningRAT tool.'

'Rule helps to detect a rare user-agents indicating web browsing activity by an unusual process other than a web browser.'
'This composite hunting query will highlight any HTTP traffic in CommonSecurityLog web proxies (such as ZScaler) that match known patterns used by red teaming tools potentially stolen from FireEye. Most FireEye red teaming tools are designed to mimic
legitimate API activity, false positives are common. This query includes a basic check to determine how common a hostname is in you environment, and allows you to modify this threshold to remove legitimate traffic from the query results.
This query contains only a subset of potential FireEye red team tool communications, and therefore should not be relied upon alone :) .'

'Detects request to potentially harmful file types (.ps1, .bat, .vbs, etc.).'
'Query finds accounts recorded as disabled by AD in previous time period but still using proxy in current time period. Presumes default squid log format is used. http://www.squid-cache.org/Doc/config/access_log/'
'Rule helps to detect Powershell user-agent activity by an unusual process other than a web browser.'
'Detects first connection to an unpopular website (possible malicious payload delivery).'
Detects a specific user agent string and host ('api.dropbox.com') associated with an APT40 Dropbox tool, indicating potential data exfiltration or command and control activity via Dropbox.
