A critical vulnerability in Windows XP has been revealed that involves the Windows and Help support center, a Web-based feature providing technical support information to end users. The vulnerability can potentially allow a remote hacker to take complete control of a victim’s machine. Systems running Windows XP and Windows Server 2003 using many major browsers, including Internet Explorer 8, are affected. A few days after the advisory, security firm Sophos warned users of a website using the vulnerability to install malicious software on victims’ machines, and of possibly more exploits coming out soon. Users of Windows XP and Windows Server 2003 are advised to disable features within Help Center that allow administrators to remotely log onto their machines. For individual users, Microsoft has released a patch for the flaw. Don’t know how to install the patch? Need help? Let us know!

A recent report , released by Osterman Research and sponsored by software vendor Commtouch, reports that the incidents of outbound spam is getting worse. The research firm interviewed 266 end users of internet service providers and 100 web hosting companies. Almost 40% of respondents have had their IP addresses listed on Real Time Blackhole Lists (RBLs) in the past 12 months alone – and the number could be far greater considering those who may not be aware that they have been listed. RBLs tag machines or networks of machines as being sources of SPAM, causing their emails to be filtered out by many mail servers. This can result in legitimate emails not reaching their intended destination, and can victims’ reputations. In addition, having an infected machine or network of machines can waste bandwidth and slow down outbound connections. The cause of outbound spam varies, but can including everything from compromised email accounts to “zombie” machines – machines infected with malware sending out spam unbeknownst to the user. There are multiple ways of protecting computers and networks against the risk of outbound spam, and our Managed Services clients benefit from our proactive protection and filtering.
