We hate to be bearers of bad news, but it looks like those of you squeaking by on a WEP-protected or unprotected wireless router have yet another reason to undertake the difficult task of selecting "WPA" on that router admin screen. A team of researchers at Indiana University have published a paper on how easily malware could spread through a densely populated area, with unprotected routers providing zero resistance, and WEP moderately more, while WPA proved generally unhackable. The spread of the malware was alarmingly similar to a biological virus, and while no such router "WiFi flu" has yet been developed by nefarious types, it's probably only a matter of time before something of its ilk takes a city by storm. In test attacks, after the initial infection phase, 10-55 percent of the routers were infected. We can do better, people. Oh, and to the guy upstairs: thanks for all the WiFi these years, those torrents will probably never be traced back to you, so don't worry.
