Hunts for sqlservr.exe spawning command shells or system utilities, a pattern consistent with xp_cmdshell abuse. It also flags later steps from a public intrusion write-up: certutil decoding, SAM, SYSTEM or SECURITY hive saves and local account or group changes.

Results are grouped per device and day and ranked by stage count. Rows can also appear without a SQL parent when two later stages occur on the same device and day.

Triage: Some jobs use xp_cmdshell legitimately. Review the command line and the account. Hunting query, not an alert.

Limitations: Activity inside the SQL process with no child process is not visible. Renamed tools, obfuscation and privilege escalation tools are not covered. Needs Defender for Endpoint on the SQL servers.

Detects commands executed on a Barracuda load balancer. Network appliances sit
outside most endpoint monitoring, so their own audit trail is frequently the only
record that anyone logged in and did something.

Onboarding: BARRACUDA-LOADBALANCER is ingested via Syslog (CEF) (Bloo extractor 859).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=auditd where sourcename='BARRACUDA-LOADBALANCER' and action='SESSION_ENDED'
| groupby user, process, commandline

Detects a privileged command executed through Centrify on Windows. Brokered
elevation records the command under the identity that requested it rather than the
shared administrative account it ran as, which restores attribution that local
Windows auditing frequently loses.

Onboarding: CENTRIFY-AUDITTRAIL-WINDOWS is ingested via Syslog (KV) (Bloo extractor 821).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

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