Eavesdropping

Eavesdropping, using packet-sniffing tools, allows attackers to read transmitted information, including logon information and database contents. Eavesdropping can yield information, such as credit card information, which can be used in later transactions, damaging both the customer and the business that allowed the breach.

A related problem involves eavesdropping and session replay in which the attacker retransmits the captured data, such as a session logon sequence to gain access to network resources.
