Bad guys will take advantage of natural disasters, such as the recent earthquakes in Japan and Ecuador, to send out emails that allegedly have links to sites where you can donate to help the victims. In reality this may be a scam, and you may be donating to the bank accounts of these scammers. Not only that, following these links may also download malicious content to your computer. US-CERT has a number of steps you can take to stay safe – with possibly the number one step being not to follow a link that is an unsolicited email.
