In the past, US-CERT has received reports of phishing scams and malware campaigns related to topics that are of high-interest to the U.S. Government or news media, such as Hurricane Irene. Users' systems have been compromised by receiving and accessing phishing emails with subject lines that seem relevant to a high-interest subject and appear to originate from a valid sender. US-CERT reminds users to remain vigilant for potential malicious cyber activity seeking to capitalize on interest in Hurricane Irene.
