There is a VERY nasty organisation out there calling themselves "Home Energy Support" making themselves out to be independent energy advisors.
They are cold calling homes and sending multiple nuisance emails with increasingly 'blunt' verbage. The latest includes apologies for being alarmist and I have been prompted to send the to the City Of London police at "report@phishing.gov.uk". This is usually safe but these orphans have a trick up their sleeve, forwarding triggers a worm. This worm attempts to link with "cricktoon.org", no doubt to download an even nastier form of itself.
If you see this, do not forward it, deleted the orphan minus a name.
Going by past evidence this is either Russian, Chinese or North Korean but the Philippines are also a source for these attacks.
Stay safe folks.
