Eavesdropping is secretly listening to the private conversation of others without their consent, as defined by Black's Law Dictionary.[1] The practice is commonly believed to be unethical.

EtymologyEdit

The verb eavesdrop is a back-formation from the noun eavesdropper ("a person who eavesdrops"), which was formed from the unrelated noun eavesdrop ("the dripping of water from the eaves of a house; the ground on which such water falls").[2]

An eavesdropper was someone who stands at the eavesdrop (where the water drops, i.e., next to the house) so as to hear what is said within. The PBS documentaries, Inside the Court of Henry VIII (April 8, 2015)[3] and Secrets of Henry VIII’s Palace (June 30, 2013) include segments that display and discuss "eavedrops", carved wooden figures Henry VIII had built into the eaves (overhanging edges of the beams in the ceiling) of Hampton Court to discourage unwanted gossip or dissension from the King's wishes and rule, to foment paranoia and fear,[4] and demonstrate that everything said there was being overheard; literally, that the walls had ears.[5]


TechniquesEdit

Eavesdropping can also be done over telephone lines, email, and other methods of instant messaging considered private. (If a message is broadcast, it is not considered eavesdropping.) VoIP communications software is also vulnerable to electronic eavesdropping via infections such as trojans.

Network attacksEdit

Network eavesdropping is a network layer attack that focuses on capturing small packets from the network transmitted by other computers and reading the data content in search of any type of information. This type of network attack is generally one of the most effective as a lack of encryption services are used. It is also linked to the collection of metadata. Those who perform this type of attack are generally black hat hackers; however, government agencies, such as the National Security Agency, have also been connected.
