I started to hear about this from numerous sources so read up a bit. I spoke to the reverse engineers and they said that it sounds like you are screwed when it has encrypted things. They are hoping to get a copy to actually take apart but this could be very simple and still very effective.
Folks, don't open attachments from emails unless:
- You were expecting the content
- The email matches what you would expect from this person
If it comes from a company, question:
- Why are they mailing you?
- Is it at all likely this is not a scam?
- How would they get that email address?
Banks you have online accounts should not send you links or attachments. If there is an link, ignore it and follow your usual log in process.
Finally, if it sounds too good to be true. It probably is.
As said, have back ups, burn to DVD's every so often, and run Anti-virus/malicious code detection.
I also own a few domain names (@whateveriwant.com), these forward emails to another address so I can re-route emails. When i use an online service I sign up with an address for that web site
google@whateveriwant.com,
pinballinfo@whateveriwant.com. This allows me to track which companies have lost control of their email lists. I can then block those email addresses later.
