This morning I received an email claiming to come from Facebook. It claimed that they were implementing new security measures and I would have to update my account.
It all looked very authentic, right up until the bit at the bottom of the message where it said:
This message was intended for xxxxxxxxxxx @ trapperindustries.com.
I don't remember setting up a company called Trapper Industries, which appears to sell deactivated weapons and military hardware. I guess the email wasn't intended for me after all.
