Barence writes: Security experts at the University of Calgary are warning against a new adware threat — dubbed Typhoid — that could display adverts to Wi-Fi hotspot users. The new threat mirrors typhoid, with healthy carriers passing on the effects of the virus to anyone they come into contact with, without showing signs of infection themselves. According to the research, the adware convinces computers within range to communicate with the infected PC rather than the legitimate access point. According to the researchers, Typhoid adware works over any non-encrypted wireless connections, and can carry a potential payload as well as irritating marketing.
