The US-CERT Current Activity web page is a regularly updated summary of the most frequent, high-impact types of security incidents currently being reported to the US-CERT.
Users should be aware of potential email scams, fake antivirus, and phishing attacks regarding the Mississippi flooding disaster. Email scams may contain links or attachments that may direct users to phishing or malicious websites. Fake antivirus attacks may come in the form of pop-ups that flash security warnings and ask the user for credit card information. Phishing emails and websites requesting donations for bogus charitable organizations commonly appear after these types of natural disasters.
US-CERT encourages users to take the following measures to protect themselves:
