Because there is such a huge demand for Google+ invites among internet users, many scammers are taking advantage of this. If you are seeking a Google+ invite, you need to make sure you know what to look for so you don’t end up at a fake pharmaceutical spam site.
On the NakedSecurity blog, Graham Cluley, senior technology consultant at Sophos, warned that spammers are currently sending out fake Google+ invitations that will then direct users to online pharmacies. It’s tricky because the message does look similar to the actual e-mails that a user might receive from friends who have accounts on Google+ already.

So far, Google+ has only been launched to a limited audience, and users have been allowed to invite their friends to join. As you can imagine, there has been a lot of interest and a high demand for these invitations. People have even been searching on eBay for invitations.
Scammers are taking advantage of this high demand by sending these fake invitations in the hopes that users will get the pharmacy sites in their quest to check out the hottest new trend in social networking, Google+. The online pharmacy offers drugs like Cialis, Viagra, and Levitra.
These kinds of fake invites and e-mails have been present before. When Myspace was more popular, for example, there were some scammers who set up a login page that looked exactly like the Myspace login page but actually had a different URL. Many users didn’t pay attention to the URL, though, and just entered their login information as usual. Then scammers would have their e-mail addresses and possibly access to other account information.

These kinds of scams can be relatively harmless where your e-mail address is just being collected for future spam e-mail campaigns. On the other hand, they can also be harmful, sometimes stealing credit card or password information.
The best way to prevent this is to pay attention and be aware of what sites you are visiting and links you are clicking on. When you enter in password, personal, account, or credit card information, double check to make sure you are on a reputable website. Double check the URL and make sure the URL address is what you think it is. Double check the website you are on to make sure there is nothing suspicious so you won’t fall prey to these scams
