We have observed a large wave of Canada Revenue Agency themed phishing emails sent from a wide variety of addresses (most coming from compromised accounts in Japan. The emails are well-written and contain a link to an Amazon site, which redirects to a phishing domain hosting a convincing CRA look-a-like website.
The subject lines can vary a little.
Please do not be curious and do not open these links as sometimes they may contain malware to infect your computer instantly.
