Unleash the BlackSheep

[Basil Chupin]

Researchers from security firm Zscaler have published free software that 
detects when users' web connections are being monitored by a 
controversial tool that steals log-in credentials from Facebook, Google 
and dozens of other websites.

Dubbed BlackSheep, the Firefox extension alerts users when computers on 
a local area network are using FireSheep to steal unencrypted cookies 
the websites use to grant users access to their account pages. When 
BlackSheep detects the snoop software in a hotspot or other open Wi-Fi 
network, it displays a message that reads “Somebody is using FireSheep 
on this network.” It then displays the LAN IP address of the offending 
party.
