Spammers Exploit Craze for Google+ Invites

Cyber security firm Sophos exposed a Google+ invite scam that sends out invites that look like the real thing, except the link takes the tricked users to a pharmacy Web site that sells Viagra. The site even features a special July 4th sale.
Taking advantage of overwhelming demand and offering something too good to refuse is a tried and true technique criminals use online.
For example, back when Gmail invites were a hot commodity, criminals sent out a bogus email to Gmail users to inform them that they have more Gmail invites. To activate these new invites, all they have to do is type in their username and password in a submission form.
