This rule performs an indicator of compromise (IOC) sweep for activities associated with the TOPHIT / VHX Harvester / @prime0 NPM typosquatting campaign. It detects known malicious C2 network connections (IPs and URLs), file artifacts (hashes) on endpoints, and suspicious email activity involving specific operator email addresses.

This rule detects known-malicious activity associated with Warlock ransomware and the ToolShell malware campaign (linked to Storm-2603). It monitors for process, file, and image-load events matching identified malicious file hashes, as well as network connection attempts to known malicious domains and URLs. It also includes monitoring for traffic to 'oastify.com', a domain commonly used for Burp Collaborator, which requires correlation with other indicators to confirm malicious intent.

This rule detects various malicious indicators including known file hashes, IP addresses, domains, and specific URLs associated with threat activity. It consolidates hits from process, file, and network telemetry to alert on potential compromise or communication with identified command-and-control (C2) infrastructure.

This rule performs a retrospective hunt for indicators of compromise (IOCs) associated with the ClosedQuorum malware. It identifies suspicious activity by matching against known file hashes, specific filenames, and network traffic directed towards services (such as DeepSeek, OpenRouter, Mistral, and Discord) which the malware uses for C2 or data exfiltration. The detection logic aggregates results from file system, process, and network telemetry.
Detects specific malicious Mach-O binary payloads identified as Atomic Stealer (AMOS) that are associated with Macfinger ClickFix first-stage infection campaigns. The rule uses static file signatures (Mach-O headers), specific file size ranges, and known SHA-256 hashes of the payloads.
This rule monitors network, file, and process telemetry for matches against a predefined list of malicious IP addresses, domain names, and file hashes. It flags suspicious network connections to known C2 infrastructure and the presence or execution of known malicious files based on SHA256 and SHA1 indicators.
This rule correlates multiple telemetry sources (File Events, Certificate Info, Network Events, and DNS Events) to detect known malicious indicators, including specific file hashes, IP addresses, domains, and URLs associated with malicious activity.
This rule detects potential malicious activity by matching file hashes against a known list of malicious indicators and monitoring for suspicious network connections. The network monitoring includes connections to hardcoded malicious IP addresses, specific C2 URLs, and DNS queries for known fallback domains used in malicious infrastructure when the initiating process is not a recognized web browser or wallet application.
This rule monitors endpoint telemetry for known indicators of compromise associated with the Casbaneiro/Ousaban banking trojan. It identifies activity across network connections (IPs and domain patterns), DNS queries for specific C2 domains, and the presence or execution of known malicious file hashes (e.g., PDF lures, HTA, AutoIt scripts, and payload binaries).
This rule monitors for file and process creation events associated with known MD5 and SHA256 hashes linked to the Vidar infostealer malware.
This rule performs a retrospective hunt for indicators of compromise (IOCs) associated with the ClosedQuorum malware. It identifies suspicious activity by matching against known file hashes, specific filenames, and network traffic directed towards services (such as DeepSeek, OpenRouter, Mistral, and Discord) which the malware uses for C2 or data exfiltration. The detection logic aggregates results from file system, process, and network telemetry.
This rule identifies two distinct security threats on Windows systems: the execution or presence of files matching a known malicious SHA256 hash list, and modifications to the 'PromptOnSecureDesktop' registry key, which could indicate an attempt to weaken User Account Control (UAC) protections.
Detects known AgtaBackup RAT staged installers and dropped payload via SHA-256 hash or characteristic filenames
Detects Kothamine Agent via hardcoded base64 AES-GCM key combined with C2 loop markers and plugin command strings, gated on PE structure to reduce false positives
Matches known SHA-256 hashes for the BotHelper stager (WindowsUpdate.exe) and RAT (msedge_proxy.exe)
