A company called Conducent (http://www.conducent.com also called TimeSink)
is offering to pay creators of free Microsoft Windows software if the
software contains modules to display banner ads when the software is
used. These modules are installed on the client's machine when the freeware
is installed and is added to the user's start-up entry in the Windows
Registry file without informing the user of the fact. This is an entry for
TSADBOT.exe in the
entry. Shareware the does this includes PKZipW and Cute-FTP.
When the user runs the software, an Internet connection is attempted to
a bank of computers controlled by Conducent, posting information about what
program is running and other information about the user. This seems to be
the method by which Conducent determines which software is running for
royalty payments. It also uses the information to determine which
advertising to show the user.
This is very similar to the Trojan horses that worry people so much and is
probably illegal in countries with strong privacy laws. If someone was able
to intercept these transmissions they could determine internal network and
personal information about a user. Many users would not install these
programs if the realised the nature of how the advertising works.
But an even worse fate occurs if the AdBot is thwarted in its attempts to
connect to Conducent by a firewall or other controls. It starts to attempt
to connect continually, about 10 times/second causing a huge load on local
network facilities. If it can't connect even then, it tries to connect using
Telnet and other ports with the background AdBot retrying the HTTP connects
after several hours.
