Recently, I've been receiving emails from JP MORGAN CHASE that are blatant phishing attempts. Out of curiosity I have opened them a few times, and they're just completely full of absolute junk characters; lots of symbols, essentially akin to WingDings from Microsoft Word. On my desktop computer, Mozilla's Thunderbird seemed to open the email without any issue, but the Outlook mobile app on my S20 seemed to hang significantly on this email, and thankfully I was able to close the app. There don't seem to be any ill effects from opening it, either on my Desktop or my phone, but my question is:
Can a spam email full of junk symbols and characters be problematic for certain devices? Is it an attempt to phish or to brick a device?
