Main Content
2025-yil 29-yanvar kuni O‘zbekiston davlat axborot tizimlariga keng ko‘lamli kiberhujum amalga oshirildi. Dastlabki texnik tahlillar shuni ko‘rsatdiki, ushbu hujum JNDI Injection zaifligi orqali amalga oshirilgan bo‘lib, bir nechta darajadagi xavfsizlik kamchiliklari yig‘indisi sabab jiddiy oqibatlarga olib kelgan.1️⃣ Dasturchi (Application Layer)
- Foydalanuvchi input tekshirilmagan
- JNDI tashqi manbalarga cheklanmagan
- Tashqi obyektlarni yuklash imkoniyati ochiq qolgan
- Java xavfsiz kutubxona sozlamalari to‘liq qo‘llanmagan
2️⃣ DevOps / Infrastrukturaviy xatolar
- Keraksiz portlar ochiq qoldirilgan
- LDAP va RMI tashqi trafiklari cheklanmagan
- Java security flag’lari noto‘g‘ri sozlangan
- Minimal huquqlar prinsipi buzilgan
3️⃣ Kiberxavfsizlik nazoratining yetishmasligi
- Pentest umuman o‘tkazilmagan yoki yuzaki bajarilgan
- Zaifliklar o‘z vaqtida aniqlanmagan
- Monitoring va real vaqt alert tizimlari yo‘q yoki sust bo‘lgan
Hujumchi maxsus tayyorlangan zararli JNDI so‘rovi yuborgan. Java ilova bu so‘rovni ishonchli deb qabul qilib, tashqi obyektni yuklagan va zararli buyruqni ishga tushirgan. Natijada hacker serverda masofadan buyruq bajarish huquqini qo‘lga kiritgan.
Ushbu hujum xavfli: server to‘liq nazoratga olinadi, fayllar o‘qiladi yoki o‘chiriladi, maxfiy ma’lumotlar o‘g‘irlanadi, server botnetga aylanishi mumkin.
Himoya chorasi: JNDI’ni tashqi manbalarga yopish, inputlarni tekshirish, dynamic class loading’ni o‘chirish, Java patchlarini yangilab borish, LDAP/RMI trafikni firewall bilan bloklash, monitoring va alert tizimlarini yo‘lga qo‘yish.
