Detects one internal source repeatedly blocked from reaching URLs. Persistent
attempts after a block indicate automated software rather than a person — a person
gives up, malware retries on a timer.
Onboarding: VERSA-NETWORKS is ingested via Syslog (KV) (Bloo extractor 806).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector
BQL (Bloo Query Language):
stream=webfilter where sourcename='VERSA-NETWORKS' and action='URL_BLOCKED'
| duration 1h
| groupby srcip, user
| select srcip, user, count(*) as cnt
| having cnt > 20

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).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector
BQL (Bloo Query Language):
stream=iam where sourcename='CENTRIFY-AUDITTRAIL-LINUX' and action='FILE_MODIFIED'

Detects configuration changes on the Mimecast gateway. Mail gateway policy decides
what reaches the organisation; weakening it — disabling attachment protection,
adding a bypass for a sender, relaxing URL rewriting — opens a delivery path for
everyone at once and persists until someone notices.
Onboarding: MIMECAST is ingested via Syslog (KV) (Bloo extractor 161).
Integration guide: https://bloo.io/docs/hypercloud/mimecast-connector
BQL (Bloo Query Language):
stream=authentication where sourcename='MIMECAST'

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 repeated blocked access requests through Zscaler Private Access. ZPA brokers
access to internal applications without exposing the network, so a user repeatedly
blocked is probing for applications they are not entitled to reach — the zero trust
equivalent of internal port scanning.
Onboarding: ZSCALER-SPA is ingested via the Zscaler connector (Bloo extractor 176).
Integration guide: https://bloo.io/docs/integrations
BQL (Bloo Query Language):
stream=zpa-connector where sourcename='ZSCALER-SPA' and action='REQUEST_BLOCKED'

Detects a Slack role change conferring administrative rights. A workspace admin can
read private content, export conversation history, add applications and change
retention — so this is a meaningful privilege grant in a system that holds a great
deal of candid organisational information.
Onboarding: SLACK is ingested via Slack native connector (Bloo extractor 833).

Detects a privileged session launched from Secret Server. The launch is the moment
privileged access begins, and it carries the identity, the target and the source
address together — a cleaner attribution point than anything the target system will
record about a shared administrative account.
Onboarding: SECRET-SERVER is ingested via Syslog (CEF) (Bloo extractor 844).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

Detects a source generating blocked packets across many destination ports. Branch
edge firewalls see lateral scanning between sites that a central firewall never
observes, because that traffic does not traverse the core.
Onboarding: VERSA-NETWORKS is ingested via Syslog (KV) (Bloo extractor 806).

Detects anomalous Kerberos ticket requests observed by ADAudit Plus. Service ticket
harvesting — one account requesting tickets for many services in quick succession —
is the precursor to offline cracking of service account credentials, and it is quiet
at the domain controller unless something is watching for the pattern.
Onboarding: MANAGE-ENGINE-ADAUDIT-PLUS is ingested via Syslog (KV) (Bloo extractor 830).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

Detects a user being invited into an Atlassian site. Invitation is the lowest-friction
route into a documentation estate: no exploit, no credential theft, simply an account
added by someone with the rights to do so.
Compare the invited domain against the organisation's own; an external domain
invitation outside a known partner arrangement warrants confirmation.
Onboarding: ATLASSIAN is ingested via NXLog (Bloo extractor 832).
Integration guide: https://bloo.io/docs/hypercloud/atlassian-connector
BQL (Bloo Query Language):
stream=iam where sourcename='ATLASSIAN'
