Every time I find a bad one, I mail everybody THAT it's
bad AND include a non-preachy little summary of WHY it's
bad ... including things like links to Russia or mystery
foreign addresses, non-existent companies, really vague
and general content, odd spelling and grammar. The last
bunch had South African links. By not getting preachy it's
possible to EDUCATE - give them more clues to look for in
the NEXT scam mail.

The IMPULSE is to just click the inviting link, BELIEVE
what's in the mail. Despite contrarians, humans ARE
generally optimistic and trusting. The scammers KNOW
this, it's how they make their money .....
Anyway, within a small/medium environment is IS possible
to inject some skepticism and educate about the signs of
a scam mail. Really BIG orgs though - yer screwed. For
sure SOMEBODY will be fooled.
LibreOffice and Linux VMs are REALLY valuable tools.
You can open weird mails in a protected environment,
with ClamAV, plus open MS files and PDFs with non
MS apps that won't automatically run all the macros
and aren't binary-compatible with Winders. Once in
a while you even need to use GHex or equiv to put a
microscope on things.
Meanwhile, on the Winders boxes, Norton IS pretty
good and I'd rec ZoneAlarm Anti-Ransomware thrown
in underneath as well. Won't save you against all
stupidity but it's better than nothing. Layered,
detailed, daily backups - online, offline and
layered - are the other half of the equation. Oh,
and those backups should be done on Linux/BSD boxes :-)
