Detects the execution of potential tunneling tools from temporary directories (/tmp, /dev/shm, /var/tmp) using characteristic CLI arguments such as --listen, --token, --obfs, and --ws-path, or the known binary name 'ingredi_ws'.

Detects potential Linux privilege escalation and persistence activities by monitoring for the creation of persistence scripts in post_boot.d, modifications to the sudoers.template file appending NOPASSWD, or system configuration rebuilds shortly after sudoers template changes.

Detects creation of a scheduled task named "Windows Defender Advanced
Threat Protection Service" configured to run at system startup with SYSTEM privileges
and launch an executable named defender.exe. HoneyMyte (Mustang Panda) used this exact
schtasks command to establish boot persistence for the CoolClient backdoor sideloader,
masquerading the task and binary as a legitimate Windows Defender component.

Detects when the IIS worker process (w3wp.exe) spawns common system and network discovery utilities such as whoami, ipconfig, systeminfo, net, and others, which may indicate web shell activity or post-exploitation discovery.

Sweeps network, process command-line and URL-click telemetry for the Kimsuky payload C2 domain and its subdomains using an anchored match, which avoids lookalike or suffix-matching domains.

Detects the launch of bad-bpf style eBPF rootkit loaders (pidhide with --pid-to-hide, sudoadd with --username) executed via sudo or from an interactive shell parent, representing the userspace step that issues bpf(BPF_PROG_LOAD) before tracepoint hooks go live.

Sweeps Defender XDR telemetry for known NEBULA / KNTRAT indicators (SHA256 hashes, C2 IP, decoy domain and URLs, burner publisher emails). Hash matching is scoped per table (execution hash only in process events), noisy tooling is excluded from command-line matches, network hits are limited to connection events, and results are aggregated per device and IOC.

The following analytic detects the execution of the macOS osascript utility with AppleScript commands that display a dialog or alert containing potentially deceptive, credential-related, or security-themed content.
Adversaries may abuse osascript to present fake system messages or credential prompts and trick users into disclosing sensitive information.
This detection is based on command-line content and should be reviewed with the parent process, executing user, script content, and surrounding endpoint activity.

Detects commands run on an F5 BIG-IP appliance. BIG-IP terminates TLS for the
applications behind it, which means the appliance holds private keys and sees
decrypted traffic — compromise of the load balancer is compromise of everything it
fronts, and the appliance itself rarely runs any endpoint agent.

Onboarding: F5BIGIP is ingested via Syslog (Bloo extractor 81).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=auditd where sourcename='F5BIGIP' and action='USER_COMMAND_EXECUTED'
| groupby user, process, commandline, processargs

Detects a privileged command run through Centrify on Linux. Because elevation is
brokered, the platform records what was actually executed under elevated rights —
a cleaner record of privileged activity than shell history, which the user can edit.

Onboarding: CENTRIFY-AUDITTRAIL-LINUX is ingested via Syslog (KV) (Bloo extractor 822).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=iam where sourcename='CENTRIFY-AUDITTRAIL-LINUX'
and action='USER_COMMAND_EXECUTED'
| groupby user, targetuser, role, domain

Detects a CyberArk threat event carrying command-line content from a privileged
session. The platform flags the session as suspicious and simultaneously records what
was typed, which gives an unusually direct view of attacker behaviour inside a
privileged context.

Review the command line in full before judging severity; PAM sessions legitimately
carry administrative commands that look alarming out of context.

Onboarding: CYBERARK is ingested via Syslog (CEF) (Bloo extractor 279).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=threat where sourcename='CYBERARK' and action='THREAT_DETECTED'
and commandline != ''
| groupby user, targetuser, commandline, process, srcip

Detects an npm or pip package installation process spawning a script
interpreter or living-off-the-land binary (powershell, cmd, certutil, bitsadmin, curl,
wget, bash, sh) as a child process. CrowdStrike's 2026 Threat Hunting Report found
adversaries increasingly embed malicious setup/install scripts inside open-source packages
uploaded to npm and PyPI; these scripts execute automatically the moment the package is
written to disk during npm install / pip install, unless intercepted before execution. A
package manager process spawning a scripting engine or download utility immediately after
install is a strong indicator of an embedded malicious postinstall/setup script rather than
a normal build step.

Detects execution of the XMRig Monero cryptominer or a miner
launched with XMRig-specific pool and tuning arguments. In the AhsayCBS
exploitation campaign attackers dropped XMRig onto compromised backup
servers to hijack CPU resources for Monero mining, severely degrading
server performance. Detection keys on XMRig binary names and the mining
command-line grammar (stratum pool URLs, donate-level and thread-hint flags).

Detects wmic being used to add a Microsoft Defender exclusion for a fake "Microsoft\Windows Defender" installation directory. HoneyMyte (Mustang Panda) runs this command via the MSFT_MpPreference WMI class before dropping the CoolClient sideloader (defender.exe) and libngs.dll into that duplicated folder, ensuring the malware is never scanned. The legitimate Windows Defender path does not contain a "Microsoft\" subfolder, making this exclusion target distinctive.
