Penyerang ransomware sekarang menggunakan taktik pemerasan tiga kali lipat

May 15, 2021 by Winnie the Pooh

Penjahat dunia maya yang berspesialisasi dalam ransomware telah menggunakan taktik pemerasan ganda di mana mereka tidak hanya mendekripsi data yang dicuri tetapi juga mengancam untuk membocorkannya ke publik kecuali uang tebusan dibayarkan. Sekarang, beberapa penyerang telah mengembangkan taktik pemerasan tiga kali lipat dengan tujuan memeras lebih banyak uang dari aktivitas jahat mereka. Dalam sebuah laporan yang diterbitkan Rabu, penyedia intelijen ancaman dunia maya Check Point Research menjelaskan bagaimana taktik terbaru ini dimainkan.

Taktik pemerasan ganda telah terbukti sangat populer dan menguntungkan di antara geng ransomware. Tahun lalu, lebih dari 1.000 perusahaan menemukan bahwa data mereka telah bocor ke publik setelah mereka menolak untuk memenuhi tuntutan tebusan. Selama waktu itu, pembayaran tebusan rata-rata melonjak 171% menjadi sekitar $ 310.000.

Tapi, taktik yang dimulai menjelang akhir 2020 dan berlanjut hingga 2021, adalah pemerasan tiga kali lipat, kata Check Point. Dalam skenario ini, penjahat mengirimkan permintaan tebusan tidak hanya ke organisasi yang diserang tetapi ke pelanggan, pengguna, atau pihak ketiga lainnya yang akan dirugikan oleh data yang bocor.

Dalam satu insiden dari Oktober lalu, 40.000 pasien klinik psikoterapi Finlandia Vastaamo terkena pelanggaran yang menyebabkan pencurian data pasien dan serangan ransomware. Seperti yang diharapkan, para penyerang menuntut sejumlah uang tebusan yang sehat dari klinik. Mereka juga mengirim email kepada pasien secara langsung, menuntut sejumlah kecil uang atau mereka akan membocorkan catatan sesi terapis mereka. Karena pelanggaran dan kerugian finansial, Vastaamo terpaksa menyatakan kebangkrutan dan akhirnya menutup bisnisnya.
