What’s happening: All software has vulnerabilities; weaknesses that cybercriminals exploit to break into computers. As software developers find these vulnerabilities, they release fixes for them.
What it means: An unpatched system is the devil’s playground.Cybercriminals gain access to computers by exploiting vulnerabilities in unpatched computers. Standard antivirus/antispyware protection may be ineffective against attacks.
What to do: Management must make sure IT staff is diligently patching computers, not just Windows but all the software on the computer. Home computers also need to be patched. Consider replacing antivirus/antimalware with intrusion newer detection and prevention.
Brian Krebs; Washington Post: Apple has shipped a security update to fix multiple vulnerabilities in the iPhone and iPod Touch. The company also pushed out a patch to plug security holes in Windows and Mac versions of its QuickTime media player … The QuickTime update brings that software to version 7.6.4 and fixes at least four separate security problems. Apple users can grab the update via Software Update, while Windows users will need to use the bundled Apple Software Updates application. The iPhone and iPod Touch updates are only available through iTunes.
