Why it matters

If genuine, the corporate addresses give attackers a ready target list for phishing and business email compromise posing as rental invoices or account notices. There is no confirmation of a breach, but customers are exposed to fraudulent billing and account notices.

What to do

Tell customers and staff to treat unexpected billing emails with suspicion and reset passwords. Watch United Rentals official channels for confirmation or further guidance.
