TOP OF THE NEWS
Google to Limit Windows Chrome Extensions to Those From Chrome Web Store (November 7, 2013)Starting in January 2014, Users of Chrome on Windows will be permitted to install extensions only from The Chrome Web Store. Currently, users are asked if they want to install extensions when they originate outside of the Chrome store, but attackers have found methods to bypass that warning mechanism.
[Editor's Note (Pescatore): Google has slowly been making the Android and Google Play App Store look much more like the Apple App Store as far as getting the App Store mechanism in between Android users and applications. The iPhone/iPad experience has shown this form of whitelisting software is a tremendous advance in security - and the users love it. So, Google extending this approach to browser plug-ins is a really, really good thing. I'd like to see competition between these white lists (and others) on the % of malicious/privacy threatening apps that get in but then get revoked/removed, in addition to their current competition on total number of apps. That would require some transparency - which one of them will step up first to provide such data? ]
FBI Adds Five to Most Wanted List of Cybercriminals (November 6 & 7, 2013)The FBI has a Most Wanted list specifically for cyber criminals. The agency recently added five names to that list, bringing the total number of most wanted for cybercrimes to 17. Among the newest additions are Andrey Nabilevich Taame, who is wanted in connection with DNSChanger, and Alexsey Belan, who allegedly broke into major ecommerce companies, stole user databases and encrypted passwords, and sold the information. Losses incurred as a result of Belan's alleged activity exceeded US $100 million.
FBI's Cyber's Most Wanted:
DHS Inspector General Warns Over Lack of Effective Warning System for Cyber Events (November 5, 2013)According to an October 24 report from the US Department of Homeland Security (DHS) Office of the Inspector General (OIG), the US government lacks a digital warning system for cyber incidents; there is no means of sharing alerts about computer breaches between agencies or with private industry. There is a system to distribute event reports and another for distributing response information, but the two are not connected. The IG's report makes seven recommendations, including acquiring or developing tools and technologies that can link situational awareness products to cyber incidents.
[Editor's comment (Northcutt): It freaks me out that the conversations that we were having in 1997 are still being repeated with the exact same words in 2013. Some how, we need to move forward.]

THE REST OF THE WEEK'S NEWS
Zero-Day Office Flaw Will Not Be Included in Microsoft's November Patch Tuesday (November 7, 2013)On Tuesday, November 12, Microsoft plans to issue eight security bulletins to address flaws in Windows, Office, and Internet Explorer. Three of the bulletins are rated critical; the other five are rated important. A recently disclosed flaw in Office that is being actively exploited will not be addressed in this batch of fixes.
Microsoft Issues Temporary Fix for Zero-Day Office Flaw (November 5 & 7, 2013)Microsoft has released a stopgap measure to temporarily fix a vulnerability in its Office suite that is being actively exploited through maliciously crafted Word documents. Microsoft has released mitigation, known as a "Fix It," which should help protect users' machines until a patch is available. The attacks are occurring mainly in South Asia and the Middle East. The flaw affects Office 2003, Office 2007, and Office 2010 on Windows XP and Server 2003. New reports indicate that exploits of the flaw may be more widespread than initially believed. Internet Storm Center:
Bitcoin Wallet Service Loses US $1.2 Million in Attack (November 7, 2013)TradeFortress has closed the bitcoin web wallet service Inputs.io after attackers exploited a flaw to steal US $1.2 million in bitcoins. The attacks occurred on October 23. According to a statement from TradeFortress, "the attacker compromised the hosting account through compromising email addresses." TradeFortress also said that he would recommend storing bitcoins only on computers not connected to the Internet.
[Editor's Note (Murray): Today everything is connected to the Internet almost by default. That said, in a world of cheap computers, one need not do one's banking on the same system that one uses for browsing and e-mail.
(Shpantzer): As with traditional online banking, if the endpoint is properly compromised, hope is all but lost. Unlike FDIC insured consumer accounts and personal account contractual agreements with the banks, I don't know how the bitcoin economy is planning on reimbursements for loss, if at all. ]
Google Engineers Angry Over NSA and GCHQ Snooping (November 6 & 7, 2013)Google has begun encrypting traffic between its data centers after leaked documents indicated that the NSA and GCHQ had been targeting the fiber-optic networks that transmit data between Google data centers in a data harvesting operation dubbed MUSCULAR. (For the record, the operation also snooped on traffic between Yahoo data centers.) The traffic was not encrypted before because it was considered internal to the company. Google executive chairman Schmidt was vocal about his feelings regarding the situation, calling the operation "outrageous" and "perhaps illegal." Google engineers have also vociferously expressed their anger about the situation.
[Editor's Note (Pescatore): Google's engineers didn't do much of a risk analysis here. There has always been a risk of governments tapping into fiber optic networks. After the terrorist attacks of 2001, many businesses moved their backup data center's further away from the main data center and looked at the risk of compromise of the fiber runs between the data center. Government interception (by US, China, others) was a known risk as early as 2000, with much public validation by 2003, and I believe that in around 2005 SANS published a white paper on how much easier it had become. Businesses that decided they did not want to risk any eavesdropping on fiber put high speed encryptors on those links, which appears what Google has now belatedly decided to do.
(Honan): If you are not fully in control of a system or its network then you should not consider it "internal to the company". Indeed, depending on the sensitivity of the data being transmitted on your network, serious consideration should be given to encrypting it to mitigate the insider threat. ]
Apple's Transparency Report Includes "Warrant Canary" (November 6 & 7, 2013)Apple has filed its first transparency report, enumerating government requests for data from devices, iTunes, and other content services. Along with the report, Apple has filed an amicus brief with the Foreign Intelligence Surveillance Court, seeking approval to release more detailed information. Apple received the vast majority of its data requests from the US government, but also received requests from the governments of the UK, Germany, Australia, Spain, Singapore, and France. Apple's report also includes these sentences: "Apple has never received an order under Section 215 of the USA Patriot Act. We would expect to challenge such an order if served on us." The statement is called a "warrant canary" because its absence from future reports would indicate that the company had received such an order.
Silk Road is Back Online (November 6 & 7, 2013)Just weeks after US authorities arrested alleged Silk Road owner and operator Ross William Ulbricht, the underground marketplace known for offering drugs, malware, among other illicit products and services is back online. US officials shut down the site following Ulbricht's arrest. Ulbricht was identified by authorities as using the online handle Dread Pirate Roberts. The site's new administrator, who is using the same moniker, says the site will be fully functional by November 9.
Cybersecurity Not Yet Central Issue in Political Campaigns (November 5, 2013)Although cybersecurity has not yet become a central campaign issue in US politics, that is likely to "change as more elected officials begin to roll out their own cybersecurity initiatives at the local level," according to a blog post from Dominic Basulto in The Washington Post. While voters may not seem to care about the issue as much as they care about the economy or employment, cybersecurity is actually both an economic issue and an employment issue. Unfortunately, the issue is not likely to rise to the top of the heap of concerns unless the country experiences a major cyber attack.
[Editor's Note (Pescatore): It will be unfortunate when cybersecurity *does* become a central issue in political campaigns. Anyone waiting for that to improve cybersecurity at their company or government agency is simply looking for excuses to avoid actually improving security right now. ]

MISSION CRITICAL JOBS - CALL FOR COMMENTThe Council on CyberSecurity (CCS) identified 10 roles in cybersecurity that employers are saying are critical to their security and are difficult jobs to fill. They asked SANS NewsBites readers to tell them if the selection and descriptions are correct and whether any major jobs are equally critical where the skills are in such short supply. Please respond to CCSskillssurvey@sans.org with your comments. Please include the organization you work for and your roll. What makes these jobs mission critical? Each of the ten mission critical cybersecurity jobs highlighted below require technical and analytic skills well beyond those found in typical social engineering approaches to cybersecurity or in security regimes that rely principally on running vulnerability testing or packaged exploit tools. Indeed, the advanced practitioner will demonstrate not only mastery of the technical knowledge and skills necessary to protect systems and networks, they will also be able to anticipate and counter sophisticated adversarial strategies. By identifying from among these positions those most important to protecting their specific networks and systems, enterprises will be able to direct scarce human resource dollars to their highest priority critical needs. Moreover, by committing to maintain competency for these professionals, enterprises will realize a valuable skill development program for their entire cybersecurity workforce. * System and Network Penetration Tester. This mission critical cybsersecurity position requires a demonstrated ability to devise, analyze, and systematically assess the ability of systems and networks to withstand sophisticated adversaries (i.e., adversaries who have not only advanced technical skills, but also knowledge of the architecture and systems they are targeting.) Competence here is demonstrated through an advanced ability to conduct sophisticated, methodical, comprehensive technical testing of configurations, pathways, and interactions between systems that mimic the techniques employed by advanced adversaries. Mastery is demonstrated by using knowledge of advanced attack strategies to devise superior processes for security monitoring, event analysis, security architecture and engineering to defeat these strategies - whether mounted by external adversaries or insiders - which might otherwise result in data exfiltration or captured command and control of internal systems and processes. * Application Penetration Tester. This position requires the demonstrated technical abilities necessary to conduct operational testing of applications before initial deployment and as they are subsequently updated. Competence is assessed on the ability to identify the program avenues most riddled with flaws and holes that give malicious actors access to important content or systems. Applications from the web are particularly vulnerable to malicious exploitation, frequently infecting visitors' computers with troublesome viruses and other malware that can create access pathways for data exfiltration or worse. Mastery here includes the knowing how to find and exploit an application vulnerability, a skill which, in turn, allows for better code reviews, forensics analysis, threat analysis, and incident response. * Security Monitoring and Event Analyst. Competency here includes the dual abilities to identify indicators that a malicious incident has occurred and to initiate swift, appropriate, and comprehensive responses. Because savvy adversaries can construct attacks to mimic old, impotent attack vectors and create easy ways to bypass defenses, mastery here includes the ability to differentiate between incidents that represent impotent attacks from those that must be analyzed in-depth and deflected or defeated by effective and timely incident response. * Incident Responder In-Depth. This mission critical cybersecurity position requires the ability to deploy and manipulate active measures to contain incidents - including isolation, characterization, reverse engineering, and rapid and accurate assessment of the capability and activity of malicious software that has been found on agency systems. It also includes the ability to correctly identify intruder introduced local changes, suspect interactions, and targets that have been triggered to evoke malicious behaviors, as well as the ability to develop and rapidly deploy eradication tools. While less than ten percent of all malicious software must be subject to this deep analysis, these payloads are the most dangerous. Malicious software left undetected is able to burrow deeply, maintain control, and spread through agency systems, as well as leave back doors for unauthorized access at will. Undetected attacker "free time" on the network equates to freedom of malicious movement and action, including malicious behavior by insiders. Moreover, attackers can reuse tactics and tools to re-attack or maintain control over systems for long periods, taking and changing data at will. Thus, mastery of skills in this competency must reflect a deep understanding of attackers and their tools to enable the professional to thwart attempts to undercut the defensive efforts. * Counter-Intelligence/Insider Threat Analyst. Competency here will reflect deep and current knowledge of the attack surface, its most vulnerable and high value targets, and how its technical vulnerabilities may be exploited. The advanced professional will also have the skills necessary to program custom tools to detect local changes, identify suspect interactions, and watch for and respond to intrusions and exploits - reflecting up-to-the-minute situational awareness on what malicious actors are using and targeting. Because well-embedded adversaries often become privy to instructions and can work to stay a step ahead of observed defender actions, mastery in this competency will devise techniques to prevent the targeted installation of malicious software or use of techniques able to evade defenses without being spotted. Of course, to address the most advanced, persistent threats, teams of professionals must be assembled with first-rate skills to understand attackers' motivations, languages, organization, and social behaviors. With this knowledge, threat actors can be arrayed logically to create effective "cyber" profiles of malicious actors, groups and campaigns - information that would not only help enterprises become more affirmatively and effectively active on their own behalf in security posture and defense, but also inform the broader cybersecurity ecosystem of important developments in the threat landscape. * Risk Assessment Engineer. Competency here will reflect the ability to develop real time estimates of the risks associated with deploying new technologies against existing and newly discovered threats, enabling businesses and agencies to assess the resources needed to respond effectively in a prioritized way. Mastery requires significant hands-on technical expertise to assess how the threats will manifest and how to prioritize the deployment and operation of effective defenses. * Secure Coder and Code Reviewer. This professional is able to write code free of known coding flaws and weak design approaches. Competency includes the ability to check software under operating conditions in order to find and fix flaws such as maliciously introduced additions, modifications, or deletions of legitimate code. The most proficient coders possess the cognitive capacity and demonstrated ability to discover security vulnerabilities in programs while under real world operational time, quality, and cost pressures. * Security Engineer/Architecture and Design. When security is not designed in, systems and networks remain chronically vulnerable to intrusions and other malicious acts. Thus, competency here requires knowledge and skills necessary to distinguish authentic and relevant security attributes from superficial and transient approaches. It also requires the ability to maintain up-to-the-minute currency on attack techniques being used by adversaries against any of the components being engineered into new or updated systems. Experts can use their technical knowledge of current attacks to identify flaws and weaknesses in the composition and design of networks, remote access schemes, systems and applications to specify solutions, verify the solutions that have been implemented, and rapidly adjust designs based on new threat and attack information as it is acquired. * Security Engineer/Operations. The most common forms of targeted intrusions easily penetrate network and system defenses because measures for basic cybersecurity hygiene have not been put in place. Cybersecurity engineers must understand how to install and maintain such basic hygiene measures as configuration and application whitelisting, sensors for continuous diagnostics and monitoring, and real time patching of systems and applications. Mastery here includes the ability to implement and configure host and network firewalls, logging, and IPS/IDS at the highest appropriate level of security, as well as the skills to implement automated monitoring of configuration, patching, AV status, administrative rights, application white listing, and other security measures in order to give system and network administrators real time task lists not only to maintain the highest possible level of security, but also to ensure that those actions and tasks are being performed correctly and in a timely manner. * Advanced Forensics Analyst. In investigating intrusions or other malicious activity (including those which may constitute crimes or potential crimes), the advanced forensics analyst must perform many of the tasks of the incident responder in depth - with special emphasis on reverse engineering (in law enforcement, this will also include the added requirement of establishing evidence that will stand up in court). Competency here will include the clear ability to determine precisely which programs have been executed, find files that have been changed by an intruder (on disk and in memory), use time stamps to develop authoritative timelines of actions taken by intruders, find evidence of deleted files, and identify key information in browser histories, account usage, and USB usage. Mastery in this area will include the advanced ability to find unknown malware hidden in systems, also known as persistent presence.
