Penipuan phishing memiliki semua lonceng dan peluit — kecuali satu

January 22, 2021 by Winnie the Pooh

Penjahat di balik penipuan phishing baru-baru ini telah mengumpulkan semua bagian penting. Malware yang melewati antivirus — check. Template email yang memanfaatkan Microsoft Office 365 Advanced Threat Protection — periksa. Pasokan akun email dengan reputasi kuat untuk mengirim email scam — check.

Hanya ada satu masalah: para penipu menyembunyikan sandi yang diperoleh dengan susah payah di server publik tempat siapa pun — termasuk mesin pencarian — dapat (dan memang) mengindeksnya.

Peneliti Check Point menemukan hasil tangkapan tersebut saat mereka menyelidiki kampanye phishing yang dimulai pada bulan Agustus. Penipuan tiba di email yang konon berasal dari Xerox atau Xeros. Email tersebut dikirim melalui alamat yang, sebelum dibajak, memiliki skor reputasi tinggi yang melewati banyak pertahanan antispam dan antiphishing. Di dalam pesan tersebut terlampir file HTML berbahaya yang tidak memicu salah satu dari 60 mesin antimalware yang paling sering digunakan.

Setelah diklik, file HTML tersebut menampilkan dokumen yang terlihat seperti ini:

Ketika penerima dibodohi dan masuk ke akun palsu, para penipu menyimpan kredensial di lusinan situs WordPress yang telah disusupi dan diubah menjadi apa yang disebut drop-zones.

Namun, para penyerang gagal menetapkan situs tersebut sebagai terlarang untuk Google dan mesin telusur lainnya. Hasilnya, pencarian Web dapat menemukan data dan mengarahkan peneliti keamanan ke cache kredensial yang disusupi.

Berdasarkan analisis terhadap sekitar 500 kredensial yang dikompromikan, Check Point dapat mengumpulkan rincian industri yang ditargetkan berikut ini.
