US-CERT is aware of public reports of malware spreading via spam. It has been reported that malware is spreading in spam messages related to the upcoming Olympics and to fake CNN news reports. If a user clicks the link to one of these fake news reports they are prompted to install a Flash Player update. If users attempt to install the update, malware may be downloaded and installed onto their system.

US-CERT encourages users and administrators to take the following preventative measures to help mitigate the security risks:

• Install anti-virus software, and keep its virus signature files up-to-date.
• Do not follow unsolicited web links received in email messages.
• Refer to the Recognizing and Avoiding Email Scams (pdf) document for more information on avoiding email scams.
• Refer to the Avoiding Social Engineering and Phishing Attacks document for more information on social engineering attacks.
