Did You Know: PowerShell 7 Writes Script Block Logs to Its Own Event Log, Not the One Windows PowerShell Uses

Windows PowerShell 5.1 and PowerShell 7 both record script blocks as event 4104, but Microsoft documents them in different event logs, set by different policy paths. A hunt that searches only one channel can come back empty while the other holds the evidence. Collect both, and check that each one is actually turned on.

Untuned Alerts Can Hide Active Intrusions From the SOC

LONDON - Organization B had an established baseline and a finer-tuned alert system. After medium-severity payload alerts, defenders isolated compromised workstations within minutes (within 10, 2, and 20 minutes across three hosts), cutting command and control and forcing the red team into an assume-breach model. CISA's lesson for operations teams: establish and continuously maintain baselines, refine alerting so routine administrative activity is filtered, and treat untuned detection stacks as a direct cause of missed intrusions.
