Detects process execution where a shell (such as bash, zsh, cmd, or powershell) is spawned by a skill or openclaw process, and subsequently performs download activities (e.g., using curl, wget, invoke-webrequest) or establishes persistence (e.g., via cron, systemd, registry run keys, schtasks).
Detects successful Google Workspace logins from an IP address or user agent not previously seen for the user within a 24-hour window.
Detects a role change in Zendesk. An administrator can read every ticket, export
data, alter automations and add agents — and support platforms are a favoured
target for social engineering precisely because agents are trained to be helpful to
strangers.
Onboarding: ZENDESK is ingested via NXLog (Bloo extractor 831).

Detects authentication to the BIG-IP management interface. These interfaces should
be reachable only from a management network; a login from anywhere else indicates
either an exposure that should not exist or an attacker who has already reached the
management plane.
Onboarding: F5BIGIP is ingested via Syslog (Bloo extractor 81).

Detects a role change on the Mimecast platform. A gateway administrator can read
quarantined mail, release held messages and alter policy — so this grant provides
both access to content and the ability to control what the organisation receives.
Onboarding: MIMECAST is ingested via Syslog (KV) (Bloo extractor 161).

Detects modification of a monitored file on a Centrify-managed Linux host. File
integrity events on Unix servers catch tampering with configuration, authorised keys
and service definitions — the common Linux persistence routes, which leave no
registry trace and no Windows-style artefact.
Onboarding: CENTRIFY-AUDITTRAIL-LINUX is ingested via Syslog (KV) (Bloo extractor 822).

Detects a privilege change recorded by Centrify on a Linux server. Centrify brokers
privileged access to Unix estates, so it sees elevation decisions that native auditd
may record only partially — and in many estates it is the only consistent record
across heterogeneous Linux and AIX systems.

Detects heartbeat and synchronisation events in Secret Server. Heartbeat verifies a
stored credential still works on the target. Repeated failures mean the credential
has changed outside the vault — which happens when an attacker rotates it to lock the
organisation out of its own privileged account.
Onboarding: SECRET-SERVER is ingested via Syslog (CEF) (Bloo extractor 844).

Detects an account being unlocked through Centrify on Windows. Lockout is often the
only visible consequence of a password-guessing attempt; an unlock immediately
afterwards either restores a locked-out colleague or, if performed by the attacker
who caused it, clears the obstacle so guessing can continue.
Onboarding: CENTRIFY-AUDITTRAIL-WINDOWS is ingested via Syslog (KV) (Bloo extractor 821).

Detects scheduled task creation observed through ADAudit Plus. Scheduled tasks are a
long-standing persistence and remote execution mechanism, and seeing them at the
directory audit layer catches creation across the domain rather than host by host.
Onboarding: MANAGE-ENGINE-ADAUDIT-PLUS is ingested via Syslog (KV) (Bloo extractor 830).

Detects use of a credential seeded by the deception platform. Decoy credentials are
planted where an intruder will find them — in memory, in config files, in browser
stores — and are never issued to a person, so any use proves both that credential
theft occurred and that the attacker has begun using what they stole.
The source address on the use tells you where the attacker is operating from, which
is usually a host you did not yet know was involved.
Onboarding: SMOKESCREEN is ingested via Syslog (CEF) (Bloo extractor 206).

Detects account creation on the NAS. Storage appliances are often administered
outside central identity management, so a local account created on one is both
durable persistence and largely invisible to directory-based monitoring.
An account created here survives domain-level remediation entirely.
Onboarding: DISKSTATION-NAS is ingested via Syslog (Bloo extractor 826).

Detects retrieval of a privileged credential from the PAM360 vault outside normal
working hours. Credential checkout is the moment privileged access actually begins,
and an out-of-hours retrieval with no corresponding change ticket is the earliest
reliable indicator of vault misuse.
Tune the window to the customer's working pattern before deployment; a global estate
will need per-region hours rather than a single range.
Onboarding: PAM360 is ingested via Syslog (Bloo extractor 879).

Detects the removal of user accounts from a specific sensitive Microsoft Entra ID group, which may indicate unauthorized group membership changes or potential privilege escalation activities.
A BTP identity provider trust configuration was created, modified, or deleted
Detects creation of a JSP/JSPX/WAR server-side script inside
an AhsayCBS installation or web application directory. In this campaign the
actors exploited critical AhsayCBS vulnerabilities and dropped webshells into
the application web directories to maintain persistent remote access. Legitimate
deployment writes scripts from the AhsayCBS updater, not ad-hoc into web roots.

Detects a successful device-code sign-in whose session is replayed successfully within 60 minutes from a different IP and ASN. Only successful replays count (interrupt codes removed) and Microsoft first-party ASN egress is excluded.
This rule monitors Entra ID Sign-in logs for authentication events flagged by risk detections related to anonymizing infrastructure, such as VPNs, TOR exit nodes, or proxies. It identifies successful logins and aggregate sign-in volume from these IP addresses, flagging successful logins as critical due to the potential for valid account abuse through multi-hop proxy chains.
Detects registry modifications that change features of internal Windows tools (malware like Agent Tesla uses this technique)
Detects Sysmon registry events (EventCode 12, 13, 14) writing Run/RunOnce keys or Service ImagePath values that reference esetservice.exe from a user-writable path (AppData, ProgramData, Temp, Public, Downloads), excluding the legitimate Program Files\ESET install location.
Detects a successful device-code sign-in followed within 60 minutes by non-interactive replay from a different IP AND a persistence action (inbox rule, app consent, device add) from a non-original IP. Persistence is now mandatory (inner join) instead of optional, and the retired AADSignInEventsBeta table is replaced by EntraIdSignInEvents.
