BlueFish is a full-featured covert tool that allows a user to access a port on a firewall remotely and connect with a “masked” backdoor.
In current era of cloud computing, an increasing number of companies/individuals have constructed Linux VMs in the cloud, and millions of suspicious traffic is directed at each VM’s ssh processes.
Preventing unauthorised ssh access has become IT professionals’ most essential task. This is when the technology of port knocking comes into play.
