Lịch sử hack tiền chuộc và tiền điện tử

 Đầu tháng này, hàng trăm công ty từ Mỹ đến Thụy Điển đã vướng vào  cuộc tấn công ransomware thông qua Kaseya , một công ty cung cấp cơ sở hạ tầng mạng cho các doanh nghiệp trên thế giới.

Vụ tấn công Kaseya xảy ra sau các cuộc tấn công mạng gây xôn xao dư luận khác như vụ tấn công  Đường ống Thuộc địa  và  vụ tấn công nhà cung cấp thịt JBS . Trong mỗi trường hợp, bọn tội phạm có cơ hội kiếm tiền hàng triệu - và phần lớn tiền chuộc được trả bằng Bitcoin.

Keatron Evans ,  nhà nghiên cứu bảo mật chính tại Viện Infosec cho biết: “Chúng ta phải nhớ lý do chính để tạo ra Bitcoin ngay từ đầu là cung cấp tính năng ẩn danh và khả năng giao dịch an toàn, không tin cậy và không biên giới .

Khi Bitcoin ngày càng nổi bật trên các thị trường trên thế giới, các cybercrook đã tìm ra một công cụ quan trọng để giúp chúng di chuyển các tài sản bất hợp pháp một cách nhanh chóng và giả danh. Và đối với tất cả các tài khoản, các cuộc tấn công chỉ ngày càng phổ biến hơn. 

Ransomware đang gia tăng

Ransomware là tội phạm mạng liên quan đến việc đòi lại dữ liệu cá nhân và doanh nghiệp cho chủ sở hữu của dữ liệu đó. 

Đầu tiên, tội phạm xâm nhập vào một mạng riêng. Vụ tấn công được thực hiện thông qua các chiến thuật khác nhau, bao gồm lừa đảo, kỹ thuật xã hội và đánh lừa mật khẩu yếu của người dùng.

Sau khi có được quyền truy cập mạng, tội phạm sẽ khóa các tệp quan trọng trong mạng bằng cách sử dụng mã hóa. Chủ sở hữu không thể truy cập các tệp trừ khi họ trả tiền chuộc. Ngày nay, tội phạm mạng có xu hướng yêu cầu tiền chuộc của chúng bằng tiền điện tử.
