US-CERT: Waledac Trojan Horse Spam Campaign Circulating

Original release date: March 17, 2009 at 9:08 am Last revised: March 17, 2009 at 9:08 am

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.
* 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.

Swine Flu Phishing Scamx

US-CERT is aware of public reports of email scams circulating related to the Swine Flu. The attacks arrive via an unsolicited email message typically containing a subject line related to the Swine Flu. These email messages may contain a link or an attachment. If users click on this link or open the attachment, they may be directed to a phishing website or exposed to malicious code.

US-CERT encourages users to take the following measures to protect themselves:

  • Do not follow unsolicited web links or attachments in email messages.

  • Maintain up-to-date antivirus software.

  • 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.


Maintaining up-to-date anti-virus is vital. Some appliances, like the Barracuda Spam & Virus Firewalls that are used by CudaMail.com to filter mail are updated on a constant basis.

US-CERT will provide additional details as they become available.
