MalWare Removal Forum

A leading developer of Firefox has warned of a sneaky potential new form of phishing attack.

Aza Raskin, the creative lead for Firefox, explains that the approach exploits the fact that most surfers keep many tabs open during a browsing session, without really keeping track of what sites they have visited.

The so-called tabnapping attack works by using JavaScript to switch the destination page in a tab after a few seconds of inactivity. This might be done using attack script planted in an otherwise legitimate website, for example.
