Typhoid adware

Typhoid adware is a type of computer security threat that uses a Man-in-the-middle attack to inject advertising into web pages a user visits when using a public network, like a Wi-Fi hotspot.

After that the adware may insert various advertisements into the data stream to appear on the computer during the browsing session.

[1][3] At the same time running antivirus software on the affected computer is useless, since it has no adware installed.

The implemented proof of concept was described in an article written in March 2010, by Daniel Medeiros Nunes de Castro, Eric Lin, John Aycock, and Mea Wang.

[3] While typhoid adware is a variant of the well-known man-in-the-middle attack, the researchers point out a number of new important issues, such as protection of video content and growing availability of public wireless internet access which are not well-monitored.
