The mail fraud (shown below) was delivered by ordinary mail. Anyone who has seen the so-called Nigerian style (sometimes referred to 419 style) spam would have recognised it for what it was. If your blogger could use Spam Assassin to scan incoming ordinary mail, this one would have gone straight into the recycling bin.
Mail Fraud From Europe.
Although it uses an old medium, the approach is modern. The contact details are an email address email@example.com, and a Fax number.
The email address has been obtained from GMX.NET, a German ISP, with a good reputation. There are numerous references to this scam online. The scammer may have harvested details from Domain registries. On the face of it, this is a European scam.
And recently there was some paypal phishing spam that had a very high score with Spam Assassin (4.6). The subject was "Require: Update Your Profile Information". The Headers were obviously forged. For anyone, such as your humble blogger, who uses mutt or an MUA that does not automatically render HTML email, this was an obvious scam. However for the unfortunate user of older versions of Outlook (the target demographic), it was finely crafted to appear legitimate. Here is how it appeared in Google Chrome:
Paypal Phishing By www.avishproduction.com.
Except that, if you clicked on it in Google Chrome, you would see this:
Phishing Detected www.avishproduction.com.
This was detected, the same day that the spam arrived. Which is quite impressive. Your blogger can't help humbly asking if Microsoft Outlook would have detected the spam as quickly. Generally it takes Bing at least 24 hours to copy the results from Google.
The best advice for Outlook users is Don't click on anything! ... In fact Don't even read your emails!.
