Karyawan LastPass Bisa Mencegah Peretasan Dengan Pembaruan Perangkat Lunak

March 5, 2023 by Søren

Peretas mengeksploitasi kerentanan dalam perangkat lunak Plex Media Server yang ditambal pada Mei 2020. ‘Versi yang mengatasi eksploit ini kira-kira 75 versi yang lalu,’ kata Plex.

Ternyata pelanggaran besar-besaran di LastPass dapat dihentikan, atau setidaknya ditunda, jika seorang karyawan perusahaan memperbarui perangkat lunak di komputer rumah mereka.

Minggu ini, LastPass mengungkapkan peretas melakukan pelanggaran dengan memasang malware di komputer rumah karyawan, memungkinkan mereka menangkap penekanan tombol di mesin. Tapi satu pertanyaan yang tersisa adalah bagaimana malware itu dikirimkan.

Pada saat itu, LastPass hanya mengatakan(Opens in a new window) bahwa peretas mengeksploitasi “paket perangkat lunak media pihak ketiga yang rentan”, tanpa menyebutkan vendor atau kelemahan yang sebenarnya. Hal itu membuat banyak orang bertanya-tanya apakah peretas telah menyalahgunakan kerentanan yang saat ini tidak diketahui, yang dapat membahayakan banyak pengguna lain.

PCMag sejak itu mengetahui bahwa peretas menargetkan perangkat lunak Plex Media Server untuk memuat malware di komputer rumah karyawan LastPass. Namun yang menarik, kelemahan yang dieksploitasi bukanlah hal baru. Menurut Plex, kerentanan tersebut berusia hampir tiga tahun dan telah ditambal sejak lama.

Plex memberi tahu PCMag bahwa kerentanannya adalah CVE-2020-5741(Buka di jendela baru), yang diungkapkan perusahaan secara publik kepada pengguna pada Mei 2020. “Penyerang yang sudah memiliki akses admin ke Plex Media Server dapat menyalahgunakan fitur Unggah Kamera untuk buat server mengeksekusi kode berbahaya, ”kata perusahaan itu saat itu.

“Pada saat itu, seperti disebutkan dalam posting itu, versi terbaru dari Plex Media Server tersedia untuk semua (7-MAY-2020),” kata juru bicara Plex. “Sayangnya, karyawan LastPass tidak pernah memutakhirkan perangkat lunak mereka untuk mengaktifkan tambalan. Sebagai referensi, versi yang mengatasi eksploit ini kira-kira 75 versi yang lalu.”
