Original title from InformationWeek was: “Twitter For iPhone Attracts Malware”. Which is blatantly misleading.
One recent attack, which aims to swipe users’ banking information, is capitalizing on the release of the first official Twitter iPhone application. Click a link in an attacker’s Twitter post — one offending message says it’s the “Official Twitter App” — and get directed to a website hosting a Trojan application. Run it, and your Windows PC can end up compromised by a worm that’s gunning for your online banking credentials.
This is no different than using Viagra to attract people to click links, InfoWeek just wanted the site traffic.
