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'.

The following analytic detects the execution of known remote access software within the environment.
It leverages network logs mapped to the Web data model, identifying specific URLs and user agents associated with remote access tools like AnyDesk, GoToMyPC, LogMeIn, and TeamViewer.
This activity is significant as adversaries often use these utilities to maintain unauthorized remote access. If confirmed malicious, this could allow attackers to control systems remotely, exfiltrate data, or further compromise the network, posing a severe security risk.

IOC sweep for ARTEX campaign indicators: C2 host, nine proxy IPs, xcai.pro and its subdomains, and the CLAUDE.md URL across Defender, CEF/firewall, DNS and Entra sign-in telemetry. Domains match on exact host or subdomain only, connection types are limited to real connection events, and sign-ins are limited to successes and credential failures.

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.

Detects unusual volumes of redirects through WebSEAL. Open or manipulable redirects
on an authentication gateway are valuable to an attacker: a link that genuinely
begins on the organisation's own trusted domain will survive scrutiny that an
external link would not.

Onboarding: ISAM-WEBSEAL is ingested via Syslog (Bloo extractor 85).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=webserver where sourcename='ISAM-WEBSEAL' and action='REQUEST_REDIRECTED'
| duration 1h
| groupby srcip, url, uriquery, returncode

Detects web access through Meraki content filtering. Branch users frequently work
without the endpoint controls applied at headquarters, so the network appliance is
often the only layer observing where they go.

Onboarding: CISCO-MERAKI is ingested via Syslog (Bloo extractor 300).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=webfilter where sourcename='CISCO-MERAKI' and action='URL_ACCESSED'
| duration 1h
| groupby srcip, domain, url, useragent, user

Detects a threat raised by Zscaler Private Access. Because ZPA mediates every
connection to an internal application, a threat on a session means hostile activity
reaching private applications from a device that already passed authentication —
which points at the endpoint rather than the perimeter.

Onboarding: ZSCALER-SPA is ingested via the Zscaler connector (Bloo extractor 176).
Integration guide: https://bloo.io/docs/integrations

BQL (Bloo Query Language):

stream=threat where sourcename='ZSCALER-SPA' and action='THREAT_DETECTED'
| groupby user, srcip, threat

Detects a successful network admission following repeated posture compliance
failures for the same endpoint. The expected outcome of failing posture is
remediation then access; failures followed by success without remediation suggests
the check was bypassed, disabled, or satisfied by spoofed posture data.

Onboarding: CISCO-ISE is ingested via Syslog (KV) (Bloo extractor 196).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=compliance where sourcename='CISCO-ISE' and action='COMPLIANCE_CHECK'
| duration 1h
| groupby user, policy, reason, srcip

Detects a decoy asset initiating an outbound connection. A decoy should only ever
receive traffic. Outbound activity means the asset has been compromised and is being
used as a launch point, or that attacker tooling on it is calling home.

The destination is live command-and-control infrastructure and should be blocked
estate-wide immediately rather than only on the decoy.

Onboarding: SMOKESCREEN is ingested via Syslog (CEF) (Bloo extractor 206).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=threat where sourcename='SMOKESCREEN' and action='THREAT_DETECTED'
and dstip != ''
| groupby dstip, url, process, srcip

Detects a DHCP lease request from a MAC address absent from the asset inventory. DHCP
sees every device that joins the network, including those with no agent, no domain
membership and no EDR — which makes it the only reliable place to catch unmanaged
hardware appearing on the wire.

Requires an inventory of known MAC addresses to compare against; without one this
detection has nothing to anchor to.

Onboarding: WIN-DHCP is ingested via Syslog (Bloo extractor 79).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=dhcp where sourcename='WIN-DHCP' and action='IP_LEASED'
| groupby macaddress, srcip, user

This rule detects indicator of compromise (IOC) sweep events associated with the AhsayCBS campaign (CVE-2026-105133 and CVE-2026-105134) involving XMRig cryptominer activity. It checks for specific file and process SHA256 hashes, remote IP addresses, and domain connections related to known mining pools or attacker infrastructure using Sentinel Device tables.

Detects the Blackwood tunneling tool from Blinder Tunnel. Blackwood.dll is sideloaded into a signed vshost32.exe via its .config and reflectively loads Go-compiled Chisel, which dials a raw public IP and opens a reverse SOCKS proxy for lateral pivoting.

Detects SSH clients launched with reverse (-R) or dynamic (-D) port
forwarding flags, a hallmark of tunnel establishment used to pivot into internal
networks or expose internal services through a compromised host. The Blinder
Tunnel campaign leverages SSH tunneling to encapsulate C2 and lateral movement
traffic inside an allowed protocol.
