June 23rd, 2010 . by DarkFiber Consulting

Apple has released Security Update 2010-004 and Mac OS X v10.6.4 to address multiple vulnerabilities that affect a number of applications. These vulnerabilities may allow an attacker to execute arbitrary code,  cause a denial-of-service condition, operate with elevated privileges, conduct man-in-the-middle attacks, alter configuration settings, or conduct cross-site scripting attacks.

Note that these Apple updates include Adobe Flash Player plugin version 10.0.45.2, which contains vulnerabilities previously identified in Adobe Security Bulletin APSB10-14. The Adobe Product Security Incident Response Team (PSIRT) has published a blog entry recommending that Mac OS X users upgrade to the latest version of the Flash Player (version 10.1.53.64) after applying these Apple updates.

Malware Spreading via Social Networking Sites

December 8th, 2008 . by DarkFiber Consulting

DarkFiber Consulting is aware of public reports of malware spreading via popular social networking sites. The reports indicate that this malware is spreading through spam email messages appearing to come from Myspace.com, Facebook.com, and Classmates.com. The email contains a message indicating that there is a YouTube video available and instructs the user to follow the link to view the video. If users click on this link, they will be prompted to update Adobe Flash Player. This update is not a legitimate Adobe Flash Player update–it is malicious code.

DarkFiber Consulting encourages users and administrators to do the following to help mitigate the risks:

  • Install antivirus software and keep the virus signatures up to date.
  • Do not follow unsolicited links.
  • Use caution when downloading and installing applications.
  • Obtain software applications and updates directly from the vendor’s website.
  • Configure your web browser as described in the Securing Your Web Browser document.
  • Refer to the Recognizing and Avoiding Email Scams (pdf) document for more information on avoiding email scams.

United States Presidential Election Email Attack

November 6th, 2008 . by DarkFiber Consulting

DarkFiber Consulting is aware of public reports of email attacks circulating that are related to the recent U.S. presidential election. The email messages appear to be coming from a seemingly legitimate source and contain a message indicating that additional news coverage of the election is available by following a link.

DarkFiber Consulting encourages users to take the following preventative measures to mitigate the security risks:

  • Install antivirus software, and keep the virus signatures up to date.
  • Do not follow unsolicited links.
  • Use caution when visiting untrusted websites.

  • Obtain software applications and updates directly from the vendor’s website.
