Bagaimana peretas masuk ke ponsel Anda tanpa kata sandi: ahli ‘GhostTouch’

May 19, 2023 by Søren

Bahkan peretas telepon dapat bekerja dari jarak jauh akhir-akhir ini.

Para peneliti dari NordVPN telah memperingatkan pengguna ponsel cerdas untuk berhati-hati terhadap penjahat dunia maya yang licik, dengan mengklaim bahwa mereka menggunakan teknik baru yang memungkinkan mereka membuka kunci ponsel cerdas tertentu dari jarak jauh.

Biasanya, saat ponsel diretas, hal itu dilakukan dengan memasang malware di perangkat melalui kabel pengisi daya.

Para peneliti mengatakan pengguna ponsel pintar harus mengetahui teknik yang disebut GhostTouch – mendesak pengguna ponsel untuk mencari ponsel yang terbuka sendiri.

“GhostTouch adalah serangan peretasan layar terbaru yang memungkinkan penjahat meretas ponsel pengguna dari jarak jauh,” kata seorang peneliti kepada TechRader.
“Secara sederhana, penyerang menggunakan sinyal elektromagnetik untuk mensimulasikan peristiwa sentuhan utama seperti ketukan dan gesekan pada lokasi target layar sentuh.”

Para peneliti mengatakan tujuan para peretas adalah mengambil kendali jarak jauh dari ponsel cerdas untuk “memanipulasinya dengan cara yang berpotensi berbahaya”, seperti mengakses data dan kata sandi perangkat, mengakses layanan yang tidak aman, atau memasang malware.

Skema yang disebut GhostTouch ini ditemukan oleh akademisi dari Zhejiang University (China) dan Technical University of Darmstadt (Jerman).

Untuk menggunakan metode GhostTouch, peretas hanya perlu berada di dekat korban yang dituju. Mereka dapat meletakkan peralatan mereka di tempat umum untuk mengirim sinyal elektromagnetik ke telepon, yang oleh para ahli memperingatkan pengguna “bahkan mungkin tidak menyadarinya”.

“Sayangnya, tempat paling umum untuk peretasan layar sentuh adalah tempat umum seperti perpustakaan, kafe, atau lobi konferensi, tempat orang meletakkan ponsel cerdas mereka menghadap ke bawah di atas meja,” jelas Adrianus Warmenhoven, pakar keamanan siber di NordVPN. “Para penyerang menyiapkan peralatan di bawah meja terlebih dahulu dan melancarkan serangan dari jarak jauh.”
