[US] Link redirected To Another Site Hello! I RSVPed to a conference and one of the tech companies emailed inviting me to a happy hour. The email was legit and linked back to the company site. When I clicked the RSVP link it autodirected me to a page in filingorg.com. I didn't do anything or click anything on the page. The below information was already there. The inputted information is not related to me, my company, or the hosting company. Should I be concerned about phishing or anything on my computer/phone? The email linked was inst.companyname.com/bunchofnumbersandletters I have a Mac and was using chrome. iPhone and Safari. Excluded my name and the company names for privacy. Thanks!
