Detects administrative login to the FortiWeb console from an address without prior
history. Console access permits policy change and signature control, so compromise
of the WAF administrator is equivalent to removing the WAF for every application
behind it.
Onboarding: FORTIWEB is ingested via Syslog (CEF) (Bloo extractor 115).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector
BQL (Bloo Query Language):
stream=authentication where sourcename='FORTIWEB' and action='LOGIN'

Detects configuration changes on a Barracuda load balancer. Load balancer
configuration decides where traffic goes; altering a backend pool redirects users to
a destination of the attacker's choosing while the hostname and certificate they see
remain entirely legitimate.
Onboarding: BARRACUDA-LOADBALANCER is ingested via Syslog (CEF) (Bloo extractor 859).

Detects persistent blocked web requests from one internal source. A person stops
after a block; software does not. Sustained retries after blocking indicate
automation attempting to reach a destination it has been configured to use.

Detects account creation on the wireless controller. Network infrastructure accounts
are frequently local to the device, outside central identity management and never
reviewed — which makes one created by an attacker an exceptionally durable way back
into the network.

Detects one account downloading many files through GoAnywhere Managed File Transfer.
MFT platforms sit between organisations and hold exactly the data worth stealing —
payment files, payroll, partner exchanges — and have been the target of mass
exploitation campaigns precisely because they are internet-facing and rarely watched.
Onboarding: GOANYWHERE-MFT is ingested via Syslog (Bloo extractor 850).

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).

Detects an unusual rate of terminated connections at the BIG-IP. Mass termination
can indicate resource exhaustion, a denial of service in progress, or an attacker
disrupting the application tier — and the load balancer sees it before the
application does.
Onboarding: F5BIGIP is ingested via Syslog (Bloo extractor 81).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

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.

Detects one user triggering DLP repeatedly in a short window. A single violation is
usually a mistake; a pattern is either someone systematically working around the
control or an attacker testing which channels are permitted before using the one
that is.
Onboarding: TRELLIX-DLP is ingested via Syslog (XML) (Bloo extractor 805).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

Detects a rise in redirected web requests through the gateway. Redirection can
indicate traffic being steered somewhere other than the user intended, whether by
policy change or by interference further along the path.
