Adobe has issued a Security Bulletin warning of malware spreading via a fraudulent Flash Player installer. Adobe warns that a worm is making fraudulent posts on social networking sites. These posts include links that lead to fake sites that prompt users to update their versions of Flash Player. If users attempt to use the installer to make the update, malware may be downloaded and installed onto their systems.

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

• Do not follow unsolicited web links.
• Configure your web browser as described in the Securing Your Web Browser document.
• Install anti-virus software, and keep its virus signature files up-to-date.
• Refer to the Avoiding Social Engineering and Phishing Attacks document for more information on social engineering attacks.
