The CofenseTM Phishing Defense Center has observed a phishing email targeting Canadian taxpayers, similar to HMRC scams we recently reported in the United Kingdom. It’s the latest in a surge of tax-rebate phishing scams seen across the globe, prompting tax-collection agencies to issue consumer warnings.
While the message does not contain much detail, it delivers a PDF document as an attachment. This PDF document advises recipients that the Canada Revenue Agency has sent them an INTERAC e – Transfer and they can deposit the fund by following the instructions or by clicking the embedded link in the PDF. Please see Figure 1 for the email body and Figure 2 for the PDF document.

When the “Deposit your money” button is clicked, the embedded URL redirects the victim to the fake Canada Revenue Agency phishing page.
After asking the victim to enter personal details on the first page and valid financial credentials on the next page, the phish redirects the victim to the legitimate Canada Revenue Agency website (Figure 3).

Let’s dissect the message closely:
The email is crafted to appear to be from centernotify-interacraca3d-4f4[@]mtstax[.]caa tax return and bookkeeping firm in Ontario, Canada. However, the message was sent from a Virtual Private Server (VPS), hosted in Figure 4 depicts the message header.

Upon further investigation, MTS TAX is aware of this scam and have notified their customers on their web page (Figure 5).

Tips to Prevent Becoming a Victim
Finally, as always advised by Cofense, consider these best practices to avoid falling victim to such scams:
- First and foremost, be certain that you are expecting an email from the person or organization regarding the subject.
- Check the email for grammatical errors, tone and subject line of the message – consider emotional triggers i.e. urgency, fear etc.
- Don’t open any attachments unless you are certain! Even a genuine looking file can be malicious.
- Hover over a link to see where it really takes you and be cautious as there may be subtle differences between the fake URL and the genuine URL.
- Instead of visiting the URL by clicking the unknown hyperlink, search and visit your required website yourself directly.
