US-CERT is aware of public reports of malicious code circulating via spam email messages related to bogus terror attacks in the recipient’s local area. These messages use subject lines implying that a fatal bomb attack has occurred near the recipient and contain a link to “breaking news.” Users who click on the link will be taken to a site posing as a Reuters news article that contains a bogus news story about the fatal bomb attack. The systems serving the bogus news story check a visiting user’s IP address to obtain a geographical location to insert a nearby placename into the bogus article. The articles also contain links to video content, claiming that the latest Flash Player is required to view the video. If users attempt to update or install the Flash Player from the link provided in the article, their systems may become infected with malicious code.
US-CERT encourages users and administrators to take the following preventative measures to help mitigate the security risks:
Install antivirus software, and keep the virus signatures up to date.
Do not follow unsolicited links and do not open unsolicited email messages.
Use caution when visiting untrusted websites.
Use caution when downloading and installing applications.
Obtain software applications and updates directly from the vendor’s website.
