CISA urges users to remain on alert for malicious cyber activity following a natural disaster such as a hurricane or typhoon, as attackers target potential disaster victims by leveraging social engineering tactics, techniques, and procedures (TTPs). Social engineering TTPs include phishing attacks that use email or malicious websites to solicit personal information by posing as a trustworthy organization, notably as charities providing relief. Exercise caution in handling emails with hurricane/typhoon-related subject lines, attachments, or hyperlinks to avoid compromise. In addition, be wary of social media pleas, texts, or door-to-door solicitations related to severe weather events.   CISA encourages users to review the Federal Trade Commission’s Staying Alert to Disaster-related Scams and Before Giving to a Charity, and CISA’s Using Caution with Email Attachments and Tips on Avoiding Social Engineering and Phishing Attacks to avoid falling victim to malicious attacks.
