  • Engineer — Skip
  • SOC/IR — Plan: Star Blizzard’s new RedFlick delivery method and CosmicPulse backdoor warrant adding detection coverage this quarter; source the full technical write-up to extract behavioral indicators and map TTPs to ATT&CK before building Sigma/KQL rules.
  • Leader — Learn: Star Blizzard (linked to FSB) expanding its tradecraft is useful context for sector-risk assessments, but without evidence of broad enterprise targeting or a named victim in your industry, this does not require immediate leadership action.
