Bypass PIN

Peretasan Baru Memungkinkan Penyerang Bypass PIN MasterCard dengan Menggunakannya Sebagai Kartu Visa

February 20, 2021 by Winnie the Pooh

Peneliti keamanan siber telah mengungkapkan serangan baru yang dapat memungkinkan penjahat menipu terminal tempat penjualan untuk bertransaksi dengan kartu nirkontak Mastercard milik korban sambil mempercayainya sebagai kartu Visa.

Penelitian tersebut, yang diterbitkan oleh sekelompok akademisi dari ETH Zurich, didasarkan pada penelitian yang dirinci September lalu yang menyelidiki serangan bypass PIN, yang memungkinkan pelaku kejahatan memanfaatkan kartu kredit Visa EMV yang dicuri atau hilang milik korban untuk melakukan pembelian bernilai tinggi tanpa mengetahui PIN kartu, dan bahkan menipu terminal untuk menerima transaksi kartu offline yang tidak autentik.

“Ini bukan hanya kekacauan merek kartu tetapi memiliki konsekuensi kritis,” kata peneliti David Basin, Ralf Sasse, dan Jorge Toro. “Misalnya, penjahat dapat menggunakannya dalam kombinasi dengan serangan sebelumnya terhadap Visa untuk juga melewati PIN untuk kartu Mastercard. Kartu merek ini sebelumnya dianggap dilindungi menggunakan PIN”.

Setelah pengungkapan yang bertanggung jawab, peneliti ETH Zurich mengatakan bahwa Mastercard menerapkan mekanisme pertahanan di tingkat jaringan untuk menggagalkan serangan semacam itu. Penemuan ini akan dipresentasikan pada Simposium Keamanan USENIX ke-30 pada bulan Agustus tahun ini.
