Top Scams Reported in the Last 24 Hours
Fake unsubscribed spam email
Scammers are using fake unsubscribed spam emails to confirm valid email accounts to be used in future phishing and spam campaigns. These emails that ask the recipients to subscribe or unsubscribe, do not mention anything about the service. The subjects of these emails read ‘We_need your confirmation asap’, ‘Request, please confirm your unsubscription’, or ‘Verification’. Once the recipients send unsubscribe/subscribe responses, their email accounts are bombarded with spam messages.
Walmart phishing campaign
A Walmart phishing campaign is underway that attempts to steal users’ personal information. The email pretends to be from Walmart and uses the subject line ‘Your Package delivery Problem Notification ID#’ to inform recipients that their package could not be delivered to the address. The ultimate goal of the campaign is to collect information to conduct identity theft attacks.
