In the past, US-CERT has received reports of an increased number of phishing scams and malware campaigns that take advantage of the winter holiday and holiday shopping season. US-CERT reminds users to remain cautious when receiving unsolicited email messages that could be part of a potential phishing scam or malware campaign.

These phishing scams and malware campaigns may include but are not limited to the following:

* electronic greeting cards that may contain malware
* requests for charitable contributions that may be phishing scams and may originate from illegitimate sources claiming to be charities
* screensavers or other forms of media that may contain malware
* credit card applications that may be phishing scams or identity theft attempts
* online shopping advertisements that may be phishing scams or identity theft attempts from bogus retailers
