English to Spanish Tech/Engineering IT (Information Technology) Business systems security

It is important to secure our business data and information against unwanted intruders who might:

- introduce viruses that can destroy our records or slow down your computer
- intercept financial transactions, steal donor or bank details and access financial information
- mimic your online identity and pretend to be you (identity theft)
- insert malicious spyware that can sit on your computer without your authorization or knowledge
- take over one of our websites and modify it
- **piggy-back** on our Internet connection and make use of it at our expense.

¿Podría ser "colgarse" o "acoplarse"? Hay varias referencias en el glosario pero aún así me gustaría confirmar que estoy entendiendo bien.

El texto forma parte de un folleto sobre seguridad de la información para personal de un organismo internacional.

Muchas gracias.
