This one's been going around for weeks. I didn't post it here because I thought I'd got my own initial "heads-up" from
RP - but now I check back I see it was from another site. Oopsie!
If your email address is
whatever@somedomain.com, these emails will be spoofed to appear to come from
staff@somedomain.com (they are obviously working on the basis that for the majority of people somedomain.com will be their ISP's domain, so
staff@somedomain.com will look like it's come from your ISP).
Typically you'll get these every few days. Eventually you'll get one that tells you your account will be suspended in three days time if you don't run the attached "security patch". Needless to say, it won't be. It does appear that once you've ignored this 3 day warning email they give up on you. At least until the next virus trend.
