What is a sniffer program?
A sniffer is computer software that can intercept and log traffic passing over a digital network or part of a network. As data streams travel back and forth over the network, the sniffer captures each packet and eventually decodes and analyzes its content.
Most networks use broadcast technology wherein messages for one computer can be read by another computer on that network. In practice, all the other computers except the one for which the message is meant, will ignore that message. However, computers can be made to accept messages even if they are not meant for them. This is done by means of a Sniffer!
How Rocksyhoo (anti-sniffer) program works?
The best way to secure yourself against sniffing is to use encryption. While this won’t prevent a sniffer from functioning, it will ensure that what a sniffer reads is pure junk (unreadable text).
Yahoo Messenger does not use encryption. As a result of that, Instant Messaging conversations can be intercepted and logged.
Rocksyhoo provides encryption for Yahoo Messenger. Rocksyhoo will encrypt each message before it is sent and will decrypt that message after it is received on the destination computer. Both users must have installed Rocksyhoo and use the same password established by agreement in private or by public key protocol.
