Detects instances where a RedTail malware variant enumerates processes via the /proc filesystem to identify and terminate previous instances of itself using a kill signal.
This rule detects the execution of a file named 'report.bin' and correlates it with subsequent network connections originating from the same process. This behavior is indicative of a potential C2 heartbeat or exfiltration activity involving a non-standard or obfuscated executable.
This rule monitors for two distinct indicators of compromise: it detects the execution of files dropped into specific patterns within the 'AppData\Roaming' directory (associated with potential GoCaracal malware) and identifies network connections to known C2 infrastructure associated with GoCaracal and Bandook malware families.
Detects network traffic associated with SloppyRAT C2 beacons by identifying specific user-agent strings ('CommandExecutor/1.0', 'Mozilla/5.0 (compatible; DLLMemLoader/1.0)') or anomalous API path requests containing 'X-API-Key' or 'Authorization: Bearer' headers.
Detects network traffic associated with SloppyRAT C2 beacons by identifying specific user-agent strings ('CommandExecutor/1.0', 'Mozilla/5.0 (compatible; DLLMemLoader/1.0)') or anomalous API path requests containing 'X-API-Key' or 'Authorization: Bearer' headers.
Detects the presence of the known Cyclops Blink implant by file hash (SHA256) on an endpoint, followed by a network connection to associated C2 infrastructure within one hour, aligning with typical implant beaconing or file transfer behavior.

This rule detects the execution of a file named 'report.bin' and correlates it with subsequent network connections originating from the same process. This behavior is indicative of a potential C2 heartbeat or exfiltration activity involving a non-standard or obfuscated executable.
This rule detects potential cryptocurrency mining activity where known miner executables (specifically XMRig) or malicious scripts/processes are masquerading as or being spawned by 'LockAppHost.exe' or 'LockAppHost14a02b.exe'. It also monitors for subsequent attempts by these processes to terminate security-related tasks or establish persistence via registry run keys.
Detects the presence of known malicious file hashes associated with the Mini Shai-Hulud supply chain compromise (e.g., malicious npm package artifacts). The rule monitors device file, process, and image load events for SHA256 matches.
Matches known malicious dlp.sh/dlp-docker.sh Terraform module scripts used in Coder registry supply chain attack (common, aider, rstudio-server, windows-rdp, zed variants)
Detects a hardcoded PEM RSA public key embedded alongside JSCeal-specific compiled V8 bytecode obfuscation artifacts, used to encrypt exfiltrated data or C2 communications
Detects the download of a JavaScript module named JSCeal, which contains code indicative of an HTTPS interception proxy. The rule looks for Node.js-based server creation code combined with cryptographic operations like keypair generation, certificate creation, and PEM conversion, excluding common legitimate JavaScript libraries and CDNs.
Detects the CurlRAT malware interactive shell behavior where legitimate Linux system daemons (atd, crond, agetty, polkitd) are trojanized or abused to execute shell commands with attacker-supplied network endpoints (IP:Port).

Detects Adblock.dll used by Docro Hijacker to bypass Chrome Secure Preferences HMAC-SHA256 integrity checks and register infected browser UUID via vendralo[.]info
Detects the Silver Fox HVNC malware dropper initiating browser instances via the command line to access known malicious C2 domains or infrastructure. The rule specifically monitors for known malicious binaries (UpdateAssistant.exe, AppUpdateHelper.exe, SysMaintenance.exe) launching browsers with suspicious command-line parameters associated with this campaign.
This rule detects potentially malicious keylogging activity by identifying binaries named UpdateAssistant.exe or AppUpdateHelper.exe that import keylogging-related APIs (GetAsyncKeyState/GetKeyboardState). To minimize false positives, the rule correlates these findings with suspicious metadata such as unsigned binaries, untrusted signers, or execution from non-standard directories like AppData subfolders or Temp.
Detects the presence of known StyleSmuggler implant binaries (noted as Rust-based implants masquerading as gvfsd-user or kworker) by matching file SHA256 hashes.
Detects inbound network connections from known IP addresses associated with the StyleSmuggler malware distribution, which is used to inject malicious scripts into web applications.
Detects DNS lookups, TLS SNI headers, and HTTP Host headers associated with the known StyleSmuggler malware download domain '247.cdnflare.xyz'.
