Detailed Analysis

According to this email, which claims to be from American Express, a “slight error” has been detected in the recipient’s American Express account that needs to be rectified. The message claims that, unless the recipient opens an attached file and verifies account information within 48 hours, access to the account will be restricted.

However, the email is, in fact, a scam and has no connection with American Express whatsoever. Those who fall for the ruse and open the attached file will be asked to provide a large amount of personal and financial information via a web form that opens in their browser. The supposed “Card Membership Verification” form asks for credit card details, including the card’s ATM PIN as well as the user’s social security number and other identifying information along with address and contact details. The form even asks the user to provide a password for his or her email account.

But, alas, all of the information submitted on the fake form will be sent to online criminals and subsequently used to steal the identities of victims as well as use their credit card details to conduct fraudulent transactions. The scammers may also hijack the email accounts of victims and use the compromised accounts to conduct further spam and scam campaigns.

American Express would never ask its customers to verify account details by filling in an unsecure form contained in an email attachment or accessed via a clicked link. Nor would any other legitimate financial entity. Such phishing scams are very common. Other credit cards service providers, including Visa, are also regularly targeted in similar phishing scams. Be wary of any email purporting to be from a financial service provider that claims that you are required to verify your account by clicking a link or opening an attachment. This is a very common criminal ploy. If you receive such an email, do not click on any links or open any attachments that it contains.

It is always safest to login to your online accounts by entering the account web address into your browser’s address bar.  

Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
