This rule monitors NetScaler ADC logs for indicators associated with the PitScaler campaign, specifically targeting exploitation of CVE-2026-88771 and CVE-2026-88772. It detects exploitation artifacts (DTLS handshake errors, NSPPE crashes), deployment of WHIPSHOT/SLAPSHOT malware, web shell installation, httpd.conf configuration tampering, persistence mechanisms involving privilege escalation (chmod), and connections to known malicious infrastructure.
This Splunk query analyzes web logs to identify and categorize user agents, detecting various types of malware. This activity can signify possible compromised hosts on the network.
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.
Detects the Akira ransomware binary staged as C:\storage\win.exe and identified by its known SHA256 hash
Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.
Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.
Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.
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.

Detects the PoeLLM ELF payload (masquerading as libgcrypt) via Italian-language poem/agent log strings and embedded LiteLLM MCP exploit strings
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 monitors endpoint telemetry for indicators of compromise (IOCs) associated with known malicious activity. It checks for file creation, process execution, and network connections that match a defined list of malicious file hashes (SHA256, SHA1, MD5), C2 IP addresses, and malicious domains or URL patterns.
This rule detects the presence of specific SHA-256 file hashes associated with the 'VPN for X' malicious proxy extension family, which are known to be used to transform systems into nodes within a proxy network.
Detects outbound network connections to domains, URLs, and IP:Port combinations identified as malicious in the ThreatFox OSINT feed. This rule covers various commodity malware C2 and payload delivery 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.

It detects exploitation artifacts (DTLS handshake errors, NSPPE crashes), deployment of WHIPSHOT/SLAPSHOT malware, web shell installation, httpd.conf configuration tampering, persistence mechanisms involving privilege escalation (chmod), and connections to known malicious infrastructure.
This rule monitors for indicators of compromise (IOCs) associated with known malware and C2 infrastructure, including specific IP:port combinations, malicious domains, URLs for file downloads, and SHA256 hashes of known malware. The rule correlates data across device network events, file events, and process execution events to identify potential infections or communication with malicious infrastructure.
This rule detects network communication with known malicious infrastructure (C2 IPs and URLs), presence of malicious files identified by SHA256 hashes on disk, and execution of known malicious files. It also correlates these activities with specific operator email addresses involved in the malicious campaign.
