Peringatan Lorenz Ransomware: Risiko pada Sektor Layanan Kesehatan dan Sektor Publik

November 26, 2022 by Søren

Organisasi kesehatan dan sektor publik besar terus diserang oleh penyerang yang menggunakan ransomware Lorenz, pakar keamanan siber memperingatkan.

“Lorenz digunakan untuk menargetkan organisasi yang lebih besar dalam apa yang disebut ‘perburuan besar’, dan mempublikasikan data secara publik sebagai bagian dari menekan korban dalam proses pemerasan,” menurut peringatan keamanan baru dari Departemen Kesehatan dan Layanan Kemanusiaan AS.

“Relatif sedikit yang diketahui tentang Lorenz dibandingkan dengan banyak operator ransomware lainnya,” kata Pusat Koordinasi Keamanan Siber Sektor Kesehatan HHS, atau HC3.

Ransomware Lorenz pertama kali terlihat di alam liar pada Februari 2021, dan tampaknya terkait dengan ransomware sZ40 – pertama kali terlihat pada Oktober 2020 – serta ransomware ThunderCrypt, yang berasal dari Mei 2017, menurut HHS.

Di antara kesamaan: “Lorenz menggunakan encryptor yang sama dengan ThunderCrypt, yang dapat menunjukkan operasi oleh grup yang sama, atau pembelian atau pencurian kode.” Selain itu, file yang dienkripsi oleh Lorenz memiliki .Lorenz.sz40 yang ditambahkan ke nama file.

Korban Lorenz yang diketahui termasuk Wolfe Eye Clinic di Iowa, yang menjadi korban pada April 2021, dan menolak membayar uang tebusan. Informasi kesehatan yang dilindungi hingga 500.000 pasien terpapar.

Di antara korban baru-baru ini, Lorenz pada 14 November mengklaim melalui situs kebocoran datanya telah melanggar Salud Family Health of Colorado, lapor firma intelijen ancaman Kela.

KEmudian diikuti oleh Salud Family Health pada bulan Oktober memperingatkan HHS bahwa mereka telah mengalami pelanggaran pada bulan September yang mempengaruhi jumlah pasien yang belum ditentukan, seperti yang pertama kali dilaporkan oleh Databreaches.net.

Dalam pemberitahuan pelanggarannya, Salud memberi tahu para korban bahwa “nama, nomor Jaminan Sosial, nomor SIM atau nomor kartu identitas Colorado, informasi akun keuangan/nomor kartu kredit, nomor paspor, informasi perawatan medis dan diagnosis, informasi asuransi kesehatan, data biometrik, dan nama pengguna dan kata sandi” mungkin telah terungkap.
