Serangan Ransomware 2023: Sorotan Kuartal Pertama

April 21, 2023 by Coffee Bean

Pada Q1 2023, kami mengamati hampir 850 organisasi diberi nama di situs ransomware dan pemerasan data di web gelap. Ini adalah lompatan 22,4% dari kuartal sebelumnya, yang memiliki jumlah total mendekati 700. Tidak mengherankan, “LockBit” tetap menjadi grup yang paling aktif, dengan selisih yang lebar. Tapi tempat nomor dua datang dari pesaing di menit-menit terakhir: Clop, dengan eksploitasi GoAnywhere.

Jumlah korban disebutkan di 20 situs kebocoran data ransomware teratas, Q1 2023

Maret 2023 mencatat rekor bulan paling aktif yang pernah kami catat dalam sejarah ransomware pemerasan ganda. Lebih dari 400 organisasi disebutkan di situs kebocoran data ransomware; itu 35% lebih banyak dari rekor bulanan sebelumnya.

Aktivitas ransomware menurut bulan sejak Maret 2022

serangan hanya pemerasan berkurang secara substansial: sebesar 90%. Kita berbicara tentang kelompok ancaman yang mencuri data, mengancam untuk membocorkannya di situs kebocoran data, dan kemudian tidak mengenkripsi file. Terobosan dalam aktivitas hanya pemerasan mungkin dapat dijelaskan oleh kelompok pemerasan terkemuka, “Tim Peretasan Karakurt”, sebagian besar tidak aktif.

Ini tidak berarti bahwa serangan pemerasan saja sudah ketinggalan zaman. Jumlah yang dianalisis terbatas pada kelompok pemerasan yang dikonfirmasi yang menyebutkan nama korban di situs kebocoran data, dan ada ratusan pelaku ancaman yang mencuri data dan malah mengekspos organisasi di forum penjahat dunia maya bawah tanah, seperti XSS atau Exploit. Plus, kampanye terbaru Clop, yang menargetkan kelemahan GoAnywhere, dapat dianggap sebagai kampanye pemerasan saja.

Sebaran korban per sektor lebih merata, meski sektor industri barang dan jasa tetap menjadi target paling banyak dengan 21,1% dari seluruh korban. Peningkatan serangan industri perawatan kesehatan merupakan temuan penting; lebih dari 30 organisasi layanan kesehatan disebutkan di situs kebocoran data pada Maret 2023. Itu lebih dari yang kami amati selama empat kuartal terakhir.
