Fake BT Bill scam
Look out for fake BT billing emails going around.
Just received one from btconnect.biz advising me that my bill amount is 967.12 GBP and to check the attached PDF.
As the email isn't addressed to me by name, plus the fact I'm NOT a BT customer, I'm pretty confident it's a fake not to mention the domain its coming from isn't actually a BT domain, it's a fake and the PDF is probably infected, I can only recommend people delete it without viewing the PDF.
