Detects dynamic ABAP programming events (Insert, Generate, Delete) in SAP environments, excluding pre-defined authorized transactions.
Detects when a privileged SAP account modifies the master record of a different user within a specified timeframe.
Detects successful or failed logon activity by a privileged SAP account on a production system using SAP Security Audit logs.
Detects when a dialog user reads a restricted SAP table using generic table browser transactions such as SE11, SE16, or SE16N.
This rule detects when a user executes a sensitive or restricted transaction code in an SAP system, as identified by SAP security audit logs (AU3/AU4 messages). It tracks non-excluded users performing these transactions and aggregates them over a 75-minute window.
An ABAP program invoked a remote function call (RFC) using a destination resolved at runtime, which may indicate lateral movement or unauthorized internal communication within an SAP environment.
Detects multiple distinct SAP users authenticating successfully from a single source IP address within a short time window (30 minutes), potentially indicating compromised credentials or shared access anomalies.
This rule detects the use of 'docker cp' or 'sbx cp' commands which are susceptible to the CVE-2026-17106 (CopyEscape) vulnerability. This vulnerability allows a compromised container to perform arbitrary file writes or overwrites on the host system during archive extraction, potentially leading to container escape and privilege escalation by replacing critical system binaries like runc.
Detects a node/npm/npx process writing to a Unix shell startup file (.zshrc, .zprofile, .bashrc, .bash_profile) immediately after package install activity. STARDUST CHOLLIMA (DPRK-nexus) used stolen maintainer credentials to compromise the Axios npm package and deliver platform-specific "ZshBucket" malware, and separately injected a malicious dependency into 131 Mastra AI framework packages. Malicious postinstall scripts modifying shell profiles is a persistence mechanism consistent with this campaign's naming and delivery pattern.
Detects execution of esxcli syslog configuration commands where the command
itself is reconstructed at runtime from hex escape sequences, octal escape sequences, an
awk BEGIN block, or a Python chr()-based decoder before being reset against loghost.
CrowdStrike cataloged this pattern across 21 ESX BusyBox obfuscation techniques used to
hide 'esxcli system syslog config set --reset=loghost' from cleartext shell log review.
Threat actors including SCATTERED SPIDER, BlackBasta, Royal/BlackSuit, and Akira use this
to sever centralized log forwarding from a compromised ESXi host immediately before
encrypting the datastore.

Detects endpoint and network activity matching known Indicators of Compromise (IOCs) associated with BPFDoor, AVERAT, and Rekoobe backdoors based on Rapid7 research. The query checks for specific file hashes, IP addresses, and domain names across process, file, image load, network, and DNS events.
Detects the PoeLLM ELF payload (masquerading as libgcrypt) via Italian-language poem/agent log strings and embedded LiteLLM MCP exploit strings
Detects potential remote shell behavior where a process named libgcrypt establishes an outbound connection on TCP port 9999 and spawns a shell (such as sh, bash, dash, zsh, or ash) within a short time window.
Detects an exploitation attempt against PoeLLM or LiteLLM MCP test/connection endpoint using a python3 stdio payload that fetches data from port 81.
Detects endpoint connections to known DarkSword/Coruna exploit-host and C2 infrastructure. The shared AWS IP is only matched on C2 ports 8881/8882 to reduce collateral hits.
Sweeps network connection, HTTP/proxy, file, and process telemetry for exact matches against known Cling botnet indicators: dedicated STUN C2/operator IPs, Cling MIPS loader staging URLs, and known Cling sample SHA256 hashes. Tightened to exclude broad domain-level matching on stun.l.google.com (legitimate, ubiquitous Google STUN infrastructure that Cling spoofs/abuses rather than owns) and to match payload-staging hosts only by full URL rather than bare IP, reducing false positives from shared/compromised hosting and unrelated legitimate STUN traffic.
Performs an IOC sweep for a known XMRig cryptojacking campaign exploiting a REDCap vulnerability (CVE-2026-90817), detecting matching network connections, file hashes, and process activities across endpoints.
Detects network, DNS, email, and URL click events matching known IOC domains associated with AdFection, Candiru, and Discover-Tech threat intelligence reports.
Sweeps network connection, HTTP/proxy, file, and process telemetry for exact matches against known Cling botnet indicators: dedicated STUN C2/operator IPs, Cling MIPS loader staging URLs, and known Cling sample SHA256 hashes.

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 potential remote shell behavior where a process named libgcrypt establishes an outbound connection on TCP port 9999 and spawns a shell (such as sh, bash, dash, zsh, or ash) within a short time window.
