CISA warns users to remain on alert for malicious cyber activity targeting potential disaster victims and charitable donors following a hurricane. Fraudulent emails—often containing malicious links or attachments—are common after major natural disasters. Exercise caution in handling emails with hurricane-related subject lines, attachments, or hyperlinks. In addition, be wary of social media pleas, texts, or door-to-door solicitations relating to severe weather events.

Scammers are using invoices sent through PayPal.com to trick recipients into calling a number to dispute a pending charge. The missives — which come from Paypal.com and include a link at Paypal.com that displays an invoice for the supposed transaction — state that the user’s account is about to be charged hundreds of dollars. Recipients who call the supplied toll-free number to contest the transaction are soon asked to download software that lets the scammers assume remote control over their computer.
