What's happening: Cyberthieves are taking advantage of security weaknesses in Twitter to take sell them fake antivirus software
What it means: The Twitter situation corroborates IBM's recent study of web security in which they wrote: The result is "an unprecedented state of Web insecurity as Web client, server and content threats converge to create an untenable risk landscape," according to the report." See our blog posting http://citadelonsecurity.blogspot.com/2009/08/ibm-online-threat-report-trust-no-one.html.
What to do: Don't fall for online ads "scareware." Keep your systems patched -- not just Windows but Acrobat Reader, JAVA, Flash and all the other software on your PC. Keep Twitter, Facebook and other social sites out of the corporate environment. Consider replacing antvirus / antimalware solutions with intrusion detection / prevention solution.
