I have been getting a lot of strange emails from people I know, and in every case, the email contains a single sentence and link. Clearly my friends did not send me these emails. What's up with this?
I have been getting a lot of these, too, and it is amazing that the number of them has increased over the past two weeks.
The emails contain sentences like "wow this is intense you should give it a look", or "this is crazy you should check the out." (Note the excellent grammar in the previous one.) Or "wow this is pretty crazy you should look into it".
In every case the text is followed by a link. I don't know that you have to click the link to get infected by whatever this spammer is doing. Most likely the spammer has guessed your email password and has broken into your account and is just sending email to everyone in your contact list.
If you find you have been affected by this, the first thing you need to do is change your password at your online provider (for example, if your email is supplied by Comcast, browse to http://www.comcast.net and log into your email account there). Chose a new password that is difficult to guess: for best protection, select one that includes both upper and lower case letters, as well as numbers and symbols. If you just include just letters, anyone who wants to work at it can break into your account in a few seconds using a computer program built for that sort of thing.
In any case delete these emails. Don't ever click the links! Remember: just because you know who sent you the email, it isn't necessarily safe to open it!
