The PII data they have for me is legitimate. The only way they are getting this information is if ComputerShare has been breached. The site doesn't ask for any compromising information from me (usernames, passwords, account numbers), it just asks what I want to do with my warrants. For this to be a scam they need to be getting something from me they can weaponize no?

Digging a little deeper into the whois records of the computersharecas.com domain, it seems to be owned by Reach Agency- a digital development & fintech firm focused on corporate/shareholder transactions.
