Scammers are sending fake USPS messages with a link to the fake and phishing website: "my.delivery-package .q38u.live." The USPS scam messages claim there is an issue with the recipients' delivery address and their packages need to be re-delivered. The fake messages then ask them to click a link to pay a redelivery fee, but doing so will take the potential victims to a fake website looking like USPS's legitimate website.
The fake website will ask potential victims to submit their credit card information to make a payment, but if this is done, the same information will be sent to scammers instead and used fraudulently. Therefore, if you were tricked by the scam and notice any fraudulent credit card payments, report them to your bank.
