We have received reports of another JavaScript-based spam scam doing the rounds in Facebook.

This one involves a friend's profile posting a link to your wall.

Should you click on the link in the friend's post , the JavaScript code send spam to your Friends list and so the snowball spam effect grows.

TrendMirco's malware blog had a good write up of the attack method here:

Sounds like introducing friends and family to NoScript Firefox extension [1] would be one way to avoid a large number of phone calls of "Help!" over the next few days.

Thanks to reader Roseman and others for writing in with details.
