BulletProofLink

Operasi Phishing-as-a-Service Skala Besar Terkena

September 27, 2021 by Winnie the Pooh

Microsoft menemukan operasi phishing-as-a-service (PhaaS) berskala besar, terorganisir dengan baik, dan canggih.

Platform turnkey memungkinkan pengguna untuk menyesuaikan kampanye dan mengembangkan taktik phishing mereka sendiri sehingga mereka kemudian dapat menggunakan platform PhaaS untuk membantu kit phishing, template email, dan layanan hosting yang diperlukan untuk meluncurkan serangan.

Peneliti Microsoft menemukan operasi tersebut, yang dipasarkan oleh penjahat sebagai BulletProofLink, ketika mereka menemukan volume tinggi subdomain yang baru dibuat dan unik—lebih dari 300.000 dalam sekali jalan, menurut sebuah pos yang diterbitkan oleh Tim Defender Threat Intelligence Microsoft 365.

“Penyelidikan ini membawa kami ke lubang kelinci saat kami menemukan salah satu operasi yang memungkinkan kampanye tersebut,” tulis para peneliti.

Dengan lebih dari 100 template phishing yang tersedia yang meniru merek dan layanan terkenal—termasuk Microsoft sendiri—operasi BulletProofLink bertanggung jawab atas banyak kampanye phishing yang berdampak pada perusahaan saat ini, kata mereka.

BulletProofLink—juga dikenal sebagai BulletProftLink atau Anthrax oleh operatornya di berbagai situs web, iklan, dan materi promosi lainnya—memberikan titik awal bagi orang-orang tanpa sumber daya yang signifikan untuk masuk ke bisnis phishing.

Para peneliti mempelajari lebih dalam mengenai operasi PhaaS BulletProofLink untuk mengungkap bagaimana grup tersebut telah menciptakan jaringan phisher yang berkembang pesat.

Biaya layanan bulanan sebanyak $800, sementara layanan lain berharga sekitar $50 dolar untuk tautan hosting satu kali, dengan Bitcoin menjadi metode pembayaran umum di situs BulletProofLink.

Poin menarik tentang model kerja PhaaS yang digunakan BulletProofLink adalah model ini mengikuti metode pemerasan ganda model RaaS—atau dalam hal ini, “pencurian ganda”, seperti yang dijelaskan para peneliti. Grup tersebut menyertakan lokasi sekunder dalam kit phishingnya untuk kredensial yang akan dikirim setelah diperoleh.
