We see lots of phishing attempts for email, bank, PayPal, Credit card and other financial credentials. This one is slightly different than many others and much more involved and complicated, designed to make analysis and blocking by anti-phishing tools much harder. It pretends to be a message from American Express about an error on your account.

They use email addresses and subjects that will entice a user to read the email and open the attachment. A very high proportion are being targeted at small and medium-size businesses, with the hope of getting a better response than they do from consumers.

Remember many email clients, especially on a mobile phone or tablet, only show the Name in the From: and not the bit in <domain.com >. That is why these scams and phishes work so well.

This email does not come from American Express or from Amnex.com. All the sites and companies in this phishing attack  are either spoofed or compromised

The email looks like:

From: American Express <AmExpress@amnex.com>

Subject: REMINDER: A concern that requires your action.

This email has an HTML  attachment, that when opened just contains a simple instruction to run a script from a remote compromised website

If you download the script yourself, you see an encoded/encrypted file that I can’t easily decode

Note: Due to the size of the code, I have broken it up into parts A & B - sys. admin.

This is available from the anyrun report ( files section)

       
                   powered by ANY.RUN            

Once run in the browser it displays a page looking like this, asking for loads of details, so they can take over your life completely.

If you fill in the details and press submit, the information is sent to a drop site on a compromised website, http://thegrovetaunton.co.uk/robo/form.php  while you are sent to the genuine American Express site.

We all get very blasé about phishing and think we know so much that we will never fall for a phishing attempt. Don’t assume that all attempts are obvious. Watch for any site that invites you to enter ANY personal or financial information. It might be an email that says “you have won a prize” or “sign up to this website for discounts, prizes and special offers”

All of these emails use Social engineering tricks to persuade you to open the attachments that come with the email. Whether it is a message saying “look at this picture of me I took last night” and it appears to come from a friend or is more targeted at somebody who regularly is likely to receive PDF attachments or Word .doc attachments or any other common file that you use every day. Or whether it is a straightforward attempt, like this one, to steal your personal, bank, credit card or email and social networking log in details. Be very careful when unzipping them and make sure you have “show known file extensions enabled“, And then look carefully at the unzipped file. If it says .EXE then it is a problem and should not be run or opened.
