Although the floodwaters from Hurricane Harvey are finally receding, water isn’t the only thing that is flowing out. Using people’s charity to advantage, scammers loot thousands of dollars from people just trying to help others affected by Hurricane Harvey. Scammers, targeting hurricane victims and donors, send phone calls, text messages, emails and even posts on social media accounts asking for money to aid the people affected by Harvey.

“[R]emain vigilant for malicious cyber activity seeking to capitalize on interest in Hurricane Harvey,” the advisory of the United States Computer Emergency Readiness Team (US-CERT) said. “Emails requesting donations from duplicitous charitable organizations commonly appear after major natural disasters.”

In order to prevent any more scams, the following is a list of scams and how to avoid them.

1. Flood Insurance Scams: This scam takes the form of a robocall and targets homeowners throughout Texas and Tennessee. This call informs the individual that their flood premiums are overdue and that the individual must pay immediately or risk losing it all. Don’t pay anything; instead, report.

“That is pure fraud. You should only be taking information from trusted sources. If they are not a trusted source, do not rely on their information,” said Federal Emergency Management Association Deputy Associate Administrator for Insurance and Mitigation, Roy Wright.

2. Charity Scams: Numerous people have reported that they have received phone calls, text messages and emails or posts on their social media accounts asking for money for Harvey relief efforts. Don’t assume that these posts are legitimate; always make sure that the charity is reliable. Also, be alert for charities that seem to have sprung up overnight in relation to current events. In order to determine if a charity is reliable, give.org, charitywatch.org, and charitynavegator.org are all FTC-approved websites that can help you determine if a charity is legitimate. Always make sure to check the charity that you are donating to before donating money.

“We’re in the business, every day and evaluating charities,” Chief Operating Officer of Charity Navigator, Larry Lieberman said.

3. Phishing Scams: These scammers send out emails or messages on social media with links that claim to be sites where you can donate. Instead, these links send readers to bogus websites that can steal people’s credit card information, infect computers, and even their  identities. Never click on the site, even if it looks like it’s from a company that you are familiar with. A scammer could’ve mimicked what an official company’s email looks like.
