Microsoft Issues Critical, Emergency Patch: MS14-068

Microsoft on Tuesday released a critical security patch outside of its normal, monthly software update cycle to fix what it described as a serious, privately reported vulnerability in Microsoft Windows Kerberos Key Distribution Center (KDC). If left unpatched, the security hole could allow an attacker to impersonate any user on a domain, including domain administrators. They could use that access to install programs; view, change or delete data; or create new accounts on any domain-joined system, Microsoft said. The security hole affects a wide range of Windows versions and is rated Critical for all supported editions of Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2, Microsoft said. Kerberos is an encryption technology that is the default authentication method for Windows systems, starting with Windows 2000. The Kerberos Key Distribution Center is a standard network service for issuing temporary session keys to users and computers […]

When The Internet of Things Attacks! Parsing The IoT Botnet Story

I spent most of last week at a conference in Florida going deep on the security of critical infrastructure – you know: the software that runs power plants and manufacturing lines. (More to come on that!) While there, the security firm Proofpoint released a statement saying that it had evidence that a spam botnet was using “Internet of Things” devices. The company said on January 16 that a spam campaign totaling 750,000 malicious emails originated with a botnet made up of “more than 100,000 everyday consumer gadgets” including home networking routers, multi media centers, televisions and at least one refrigerator.” Proofpoint claims it is the “first time the industry has reported actual proof of such a cyber attack involving common appliances.” [Read: “Missing in action at Black Hat: the PC.”] Heady stuff – but is it true? It’s hard to know for sure. As with all these reports, it’s important […]

Windows XP Users Six Times More Likely To Be Infected By Malware

Microsoft came out with a new edition of its Security Intelligence Report today, saying that company data shows that Windows XP machines are much more likely to be infected in encounters with malicious software on the Internet. Windows XP machines were six times more likely to be infected than machines running Windows 8, the latest version of Microsoft’s operating system, the company said. The Security Intelligence Report (or SIR) is a unique window into the malicious activity online, given Microsoft’s massive footprint of more than 1 billion systems running versions of the Windows operating system, and the detailed data it collects from them through its automatic update patching- and malware removal features. This is the 15th such report Microsoft has issued.  The company used the latest report to hammer home a message about the need for Windows XP users to move off that system to a newer version of the […]
