GitHub Codespaces

Peretas Dapat Menggunakan GitHub Codespaces untuk Menghosting dan Mengirimkan Malware

January 19, 2023 by Flamango

Para peneliti telah mendemonstrasikan bagaimana pelaku ancaman dapat menyalahgunakan fitur ‘penerusan port’ GitHub Codespaces untuk menghosting dan mendistribusikan malware dan skrip berbahaya.

GitHub Codespaces memungkinkan pengembang menerapkan platform IDE yang dihosting cloud dalam wadah virtual untuk menulis, mengedit, dan menjalankan kode langsung di dalam browser web.

Menggunakan GitHub Codespaces sebagai Server Malware
Dalam laporan terbaru Trend Micro, para peneliti mendemonstrasikan bagaimana GitHub Codespaces dapat dengan mudah dikonfigurasi sebagai server web, mendistribusikan konten berbahaya sambil berpotensi menghindari deteksi karena lalu lintas berasal dari Microsoft.

Penyerang dapat menjalankan server web Python sederhana, mengunggah skrip berbahaya atau malware ke Codespace mereka, membuka port server web di VM mereka, dan menetapkan visibilitas publik.

URL yang dihasilkan dapat digunakan untuk mengakses file yang dihosting, baik untuk kampanye phishing atau untuk menghosting executable berbahaya yang diunduh oleh malware lain.

Karena GitHub adalah ruang terpercaya, alat antivirus cenderung membunyikan alarm sehingga pelaku ancaman dapat menghindari deteksi dengan biaya minimal.

Melanjutkan Serangan
Trend Micro juga mengeksplorasi penyalahgunaan Dev Containers di GitHub Codespaces untuk membuat operasi distribusi malware mereka lebih efisien. Penyerang dapat menggunakan skrip untuk meneruskan port, menjalankan server HTTP Python, dan mengunduh file berbahaya di dalam Codespace mereka.

Meskipun tidak ada penyalahgunaan GitHub Codespaces yang diketahui saat ini, laporan tersebut menyoroti kemungkinan yang realistis, karena pelaku ancaman umumnya lebih memilih untuk menargetkan platform bebas penggunaan yang juga dipercaya oleh produk keamanan.
