Recently, Neohapsis published a tool named “Sudden Six” to test if your network is vulnerable to the SLAAC attack. The tool leverages latent IPv6 connectivity that may be present in your IPv4 networked devices to alter the flow of traffic for collection and potential modification for targeted attacks.

This blog entry describes many of the recent advances Tenable has made with active and passive detection of SCADA and ICS devices on networks. There has been a dramatic increase in devices and applications that control power, industrial processes, and even our homes. With almost 600 public SCADA vulnerabilities, 214 of them disclosed in 2012, Tenable has kept pace with these advances by developing new forms of detection for Nessus and the Passive Vulnerability Scanner.

I’ll be honest – my first reaction when I heard about the SANS Consensus Audit Guidelines (CAG), was that our industry didn’t really need yet another framework or standard. But when I read them, I realized this was put together by experienced security professionals who all too often were successful on multiple occasions in breaking into systems during a penetration test at the same customer, or had to perform incident response for the same customer a third or fourth time.

How hard is it for you to prove that you are performing vulnerability scans, network monitoring and log analysis for 100% of your network? If your organization hasn’t automated this process, or it is relying on periodic manual processes, chances are you are blind in some areas and don’t know it.

When I was at RSA earlier this year, I gave a variety of media interviews and product demos about Tenable solutions. I demonstrated Nessus detecting malicious processes and the Passive Vulnerability Scanner (PVS) providing an audit trail of all network activity that led up to the infection. I also showed how the Log Correlation Engine (LCE) correlated PVS logged DNS queries to known botnets.

The Nessus malicious process detection plugins were recently enhanced to allow for searching with custom file hash lists. This allows organizations to add their own sources of malicious file hashes into Tenable's set of cloud-based hashes and botnet checks.

Recently, Tenable's Research team created Nessus checks and log searches to look for indicators specified in the Mandiant APT1 report. Our response was not unlike a typical Microsoft Tuesday afternoon where our team writes active, credentialed, and passive checks for missing patches. There are a lot of other indicator sources and, following the press surrounding the APT1 report, there will undoubtedly be more disclosures. When this steady stream of indicator disclosures starts, there will likely be an outcry from IT security professionals everywhere to align these releases to a certain day of the week for the same reasons we have Microsoft Tuesday.

The Mandiant APT1 report contains a tremendous amount of detail about attacker techniques, indicators of compromise, and possible adversaries. Most interesting was the large amount of technical detail provided about the indicators of compromise – domain names, SSL certificates, file hashes, and more. Tenable's research team leveraged this information into a wide variety of reporting and detection tools which are now available in Nessus and SecurityCenter.
