TOP OF THE NEWS
Flaws Could be Exploited to Put Critical Infrastructure at Risk of Attack (October 16, 2013)Researchers have found vulnerabilities in industrial control systems (ICS) that manage portions of the US's critical infrastructure, such as electric substations and water systems. The vulnerabilities could be exploited to crash servers, create denial-of-service conditions, or inject code. The vulnerabilities affect devices used for serial and network communication between servers and substations, and could be accessed physically or by breaking into the wireless radio network with which they communicate with master servers.
[Editor's Note (Assante): Chris and Adam are applying the necessary techniques to understand existing weaknesses in the implementations of relied upon industrial protocols. They are covering important ground in a more comprehensive manner than past efforts to identify weaknesses and educated ICS stakeholders. I am hopeful that they will bring down the myth that serial protocols and devices are not something that needs to be concerned about. Chris and Adam will talk about their research and share their tool at the SANS ICS Summit in Orlando this March! ]
NSA Chief to Retire Next Year (October 17, 2013)General Keith Alexander plans to retire from his position as director of the NSA (and Cyber Command Chief) in the spring of next year. An anonymous source indicated that Alexander's top civilian deputy, John "Chris" Inglis, would also retire from his position by the end of 2014.
[Editor's Note (Pescatore): General Alexander's tenure, the longest I can remember for a DIRNSA, spanned the transition of NSA from an intelligence collection and cryptography development/deployment agency to the addition of responsibility for offensive cyberwarfare and defensive cybersecurity after President Bush's Comprehensive National Cybersecurity Initiative and the creation of the US Cyber Command in 2007. That is an enormous span of control and the Snowden revelations seem to point out that it may be too large a span of control.
(Paller): General Alexander raised the stature of the defensive mission at NSA from a backwater to a high level of profession performance under folks like Tony Sager. By empowering the defensive mission, he built a channel allowing offensive (discovery of new vulnerabilities) to inform defense and, often over the objections of the NSA offense people, he enabled vulnerabilities to be translated into defensive guidance that actually works. NSA's guidance (including for example the new NSA Top 10) is much more valuable than the high-level essays from other federal agencies that masqueraded as security guidance. ]
Oracle Update Includes 51 Fixes for Java (October 16 & 17, 2013)Oracle has released fixes for more than 50 vulnerabilities in Java. Of those, a dozen could be exploited to take control of vulnerable systems remotely. Brian Krebs writes that if users must run Java they should update promptly. However, if they do not use Java, Krebs recommends disabling it. The most current version of Java is now Java 7 Update 45. Apple has also released an update for java on OX X. The most recent current version of Java for Mac is now 1.6.0_65 for OS X 10.6.8. Oracle also released foxes for 76 flaws in a number of its other products.
[Editor's Note (Pescatore): Reports say Larry Ellison, Oracle's CEO, spent $100M or more to have his sailboat be slightly faster than New Zealand's sailboat. Wouldn't a similar investment in making Java security a non-oxymoron feel as good?
(Shpantzer): We must abandon the term Java, instead replacing it with the term Oracle Java, or Java by Oracle. To paraphrase the old AmEx commercial: Ownership has its privileges (and responsibilities). ]

isoHunt Founder Agrees to Cease Operations and Pay US $110 Million (October 17, 2013)isoHunt founder Gary Fung will shutter all operations and pay US $110 million to the eight movie studios that sued the BitTorrent search engine. Fung accepted the judgment just weeks before a trial in the case was scheduled to begin. The settlement follows a federal appeals court ruling that found Fung liable for inducing copyright infringement. The Motion Picture Association of America (MPAA) brought the lawsuit on behalf of the movie studios.
Cisco: Suspect Crypto "Not Invoked in Our Products" (October 17, 2013)Cisco says that although cryptographic technology that is believed to be an NSA backdoor is present in some of the company's products' code libraries, it is not used, since the company designated a different cryptographic technology as an unchangeable default. The technology in question is Dual Elliptic Curve Deterministic Random Bit Generator (Dual EC DRBG).
Windows 8.1 Comes with Automatic Disk Encryption (October 17, 2013)Microsoft Windows 8.1 ships with automatic device encryption enabled by default, but the feature's hardware requirements mean that it works only on newer systems.
[Editor's Note (Shpantzer): Maybe it's OK to have this new version of Windows work only with newer devices. Backward compatibility is one of the consistent security disablers and at some point, we have to decide if backward compatibility is worth the tradeoff.
(Murray): A step in the right direction. Developers continue to be reluctant to choose "safe out of the box." ]
Purloined PR Newswire Database Found on Server Holding Stolen Adobe Source Code (October 16 & 17, 2013)Press release distribution service PR newswire has acknowledged that criminal hackers compromised a customer database containing access credentials and contact data. PR Newswire said that the database held about 10,000 records. The company is urging affected customers to change their passwords. The stolen database was discovered on the same server where stolen Adobe source code was found several weeks ago, indicating that the thefts might be connected. The same group is believed to have broken into systems at LexisNexis, Kroll Background America, and Dun and Bradstreet.
Nemim Malware Steals eMail, Browser Data (October 16, 2013)A variant of malware known as Nemim has been spreading since April and has compromised thousands of computers. Nemim has been around since at least 2006. This most recent variant includes infection, downloading, and data-stealing components. It spreads through phishing emails and uses stolen digital certificates.
US Government Sites Using Expired SSL Certificates (October 16 & 17, 2013)More than 200 US government websites appear to be using expired SSL certificates, putting site visitors at risk of having personal information stolen through man-in-the-middle attacks. Some of the expired certificates may be due, in part, to the government shutdown. According to a study from the University of California, users are likely to click through messages warning of expired certificates.
Study of Browser Security Warning Effectiveness:
[Editor's comment (Northcutt): And we are supposed to believe this is a new problem, or the result of the shutdown? Crypto should be managed with a life cycle mentality, keys should expire. And managers should be responsible to track and manage the expirations.
(Pescatore): The SSL certificate model is so broken, I'm not sure expired certificates make any difference in the actual level of security. But, they do cause user confusion and transaction abandonment - - never a good thing. Widely used vulnerability scanners, such as Rapid7, Qualys and Tenable, will find and alert on expired certificates, while specialized tools such as Venafi provide SSL certificate discovery and management capabilities.
(Murray): I am less concerned with the failure to change keys on a timely basis than I am with the proliferation of and compromise of certification authorities. It is clear that there are more organizations that aspire to this role than are competent to fill it. I assert that our single signature PKI model is broken. We need to move PKI to emulate the multiple signatures that we use in the paper system. Think "witness," "endorsement," and "countersign." The system should not break because, merely for example, Diginotar is compromised. ]
Dexter Malware Found on Point-of-Sale Terminals in South Africa (October 15 & 16, 2013)Malware known as Dexter has compromised point-of-sale terminals at thousands of businesses in South Africa. Dexter, which was first detected in December 2012, steals data from payment cards' magnetic strips and sends the information to the criminals who use it to conduct fraudulent transactions. The variant found on devices in South Africa has affected most banks in that country; hundreds of thousands of customers have had their payment card data compromised.
California Governor Vetoes Privacy Bill Again (October 15, 2013)California Governor Jerry Brown has once again vetoed legislation that would have required law enforcement authorities to obtain warrants before searching suspects' electronic communications. Governor Brown said the bill would impede investigations and would impose requirements beyond those in existing federal laws. This is the third time he has vetoed the legislation.
Governor Brown's Memo Explaining Veto:
Ploutus Malware Lets Thieves Manipulate ATMs to Dispense Cash (October 15, 2013)Researchers have detected malware that can be used to induce ATMs to dispense cash directly to thieves, bypassing the need for a skimmer and cloned cards. The malware, known as Ploutus, has been found on machines in Mexico. The thieves picked locks to gain access to the machines and physically installed Ploutus on the ATMs.
[Editor's Note (Shantzer): Physical security is a critical aspect of information security. That said, getting your grubby paws on any given box shouldn't mean you can install anything you want, and it certainly shouldn't mean you can install anything you want and not trigger alarms. ]
