한눈에 보는 오늘 : 경제 - 뉴스 : [데일리브리프 황재희 기자] 국내 자산운용사에 특화된 전산관리 서비스를 제공하는 '지제이(GJ)텍'의 서버가 랜섬웨어에 감염된 것으로 확인되면서 관련 업계에 비상이 걸렸다. 자칫 지제이텍에 전산관리를 맡긴 자산운용사에까지 불똥이 튈까 걱정하는 것이다.

Notes

  • Observed events reflect monitored leak-site and extortion activity, not independent confirmation of every intrusion.
  • Data-leak indicators reflect visible public leak evidence or escalation, which is stronger than a fresh listing alone.
  • Country, sector, and company-size metadata can be incomplete. Unknown values are excluded from the public mix views.
  • The goal is to explain concentration, escalation, churn, and patterns — not to build a wall of named victims.

Method

  • The page uses a fixed seven-day window based on the selected date.
  • Only public-facing actor and event records are included.
  • Counts and breakdowns are designed for trend review, not incident confirmation.
