TOP OF THE NEWS

Cyber Security as a Matter of Resilience (September 22, 2014)

Experts say that the cyber security conversation is better served by focusing on resilience rather than on prevention. Adm. Michael Rogers, NSA Director and commander of US Cyber Command, said that the question is "How, in the midst of degradation and penetration, can we still have confidence in the systems?"
-http://www.federaltimes.com/article/20140922/CYBER/309220008/IT-security-shifts-
from-prevention-resiliency

[Editor's Note (Weatherford): This is the new theme for cybersecurity - the ability to continue fighting when you're hurt is the differentiator between a successful security organization and the one picking up the pieces after an incident and wondering what happened.
(Murray): I have liked this idea since I first heard it three years ago. That said, resilience of the whole is improved by the "prevention" of the parts.
(Honan): Focusing on resilience provides an added advantage as it requires a shift from thinking about cyber security in pure technical terms into what does the business need in order to survive an incident? This approach brings the whole topic of cyber security to the board and senior management as they have to determine what is important from a business perspective for the organisation to survive a security incident. ]

Home Depot Ignored Security Concerns (September 19, 20 & 22, 2014)

Former Home Depot employees say that management ignored warnings from the company's computer security team that its systems were vulnerable to attack. Some team members even quit in frustration over the company's slow response to warnings of serious problems. The company was using outdated antivirus software and did not regularly scan critical systems. An engineer hired to work on the security team is now in prison for sabotaging his previous employer's network (see below).

urity_fail_laundry_list/

-http://arstechnica.com/security/2014/09/home-depot-ignored-security-warnings-for
-years-employees-say/

[Editor's Note (Murray): One should not conclude that Home Depot is a special case. Home Depot is typical of retail chains operating point of sale technology. If one is in this industry, one must follow the recommendations in the Verizon Data Breach Incident Report including strong authentication on remote access, resisting changes to the program content of point of sale systems, and monitor those systems for exfiltration of PCI data. These measures will still be necessary even if and when the industry puts in place fundamental controls (e.g., digital tokens) to resist the fraudulent reuse of credit card numbers, ]
A NOTE FROM JOHN PESCATORE ON LESSONS FROM THE HOME DEPOT BREACH: More information continues to come out about the Home Depot "biggest breach ever," reinforcing that something as simple as Critical Security Control 2, Inventory of Authorized and Unauthorized Software, implemented on Home Depot's point of sales systems would have prevented the breach. Cyberpoint has used their Cyber Value at Risk tool to show how the use of whitelisting could have prevented an estimated $246M impact to Home Depot's bottom line and SANS' John Pescatore has estimated that the worst case cost for Home Depot to implement whitelisting would have been $25M.

Former Home Depot Security Architect in Prison For Sabotaging Previous Employer's Network (September 22, 2014)

Ricky Joe Mitchell, a former Home Depot security architect, is currently serving a four-year sentence for sabotaging his previous employer's network. Mitchell was hired by the home improvement chain in 2012 and was made Senior Architect for Security in March 2013. In January 2014, Mitchell pleaded guilty to intentionally damaging the network of EnerVest Operating in June 2012 after learning that he was going to be fired. Mitchell remotely accessed the company's servers and reset them to factory settings. He also went into the office after hours and disabled the equipment cooling system. Mitchell remained employed by Home Depot after his July 2013 indictment until his January 2014 guilty plea.

Can the US Power Grid Succumb To Cyber Attacks Alone?

Last week we covered a story in which observers say that cyber attacks alone could not take down the US power grid. (
-http://www.politico.com/story/2014/09/power-grid-safety-110815.html)
Here Michael Assante provides a more nuanced and accurate answer. Mike served as CSO for American Electric Power, CSO of NERC, and as the most trusted advisor to the White House on exactly this question. Now he leads the international consortium that is defining and measuring the critical skills needed by power engineers and IT security professionals charged with ensuring such damage does not occur.

Four MIT Students Fighting Subpoenas Over Hackathon Bitcoin Mining Tool (September 22, 2014)

Four Massachusetts Institute of Technology (MIT) students are fighting a subpoena demanding they surrender the source code for a Bitcoin mining tool they created for a hackathon. A legal team from the Electronic Frontier Foundation (EFF) is representing the students. The subpoena, from the New Jersey Division of Consumer Affairs, claims that the students violated computer crime laws in that state and demanded that they turn over the source code and any attendant documentation. MIT has sent a letter to the New Jersey attorney general asking that the subpoena be withdrawn, saying that such demands have "a chilling effect on MIT teaching and research."

Google Shuts Down Malvertising Attack (September 22, 2014)

On September 19, Google shut down a malvertising campaign that affected visitors to several different websites, including Last.fm and The Jerusalem Post. The questionable ads were being served by the Zedo ad platform through Google's DoubleClick. The malicious ads were serving up a downloader known as Zermot.

Senate Bill Would Limit Power of US Warrants for Data Stored in Other Countries (September 19, 2014)

A bill proposed in the US Senate last week would limit the type of data that US authorities could obtain from foreign servers with a warrant. The legislation appears to be a response to the case in which Microsoft has refused to surrender customer emails that are stored on a server in Ireland. A US District Judge recently ruled in favor of the government, saying that "it is a question of control, not a question of the location of that information." The case is moving to appeal. The Law Enforcement Access to Data Stored Abroad Act (LEADS Act) would limit the US's warrant access to data of US citizens. To obtain data belonging to citizens of other countries, the US would have to follow that country's legal protocol. US Technology companies maintain that if they are required to surrender data belonging to non-US citizens, trust in their businesses would deteriorate.

Senate Bill Would Expedite DHS's Hiring of Cyber Security Experts (September 20, 2014)

The US Senate has passed a bill that would increase the authority of the defense secretary to hire and retain cyber security professionals. The legislation would allow DHS to hire qualified security professionals more quickly and offer them better compensation.
-http://www.govinfosecurity.com/senate-passes-cybersecurity-skills-shortage-bill-
a-7340

[Editor's Note (Weatherford): Two issues, one far more important than the other. Frank Reeder has it right that pay is NOT the main reason that DHS has a recruiting (or retention) problem. Expediting the hiring process would make a big dent in the recruiting issue very quickly and demonstrated to the many talented people who want to work for the government that they actually care. ]

eBay Vulnerability Has Been Present for at Least Six Months (September 19, 2014)

A vulnerability in some eBay postings has been present for months. The flaw has been exploited to redirect some customers to malicious websites. eBay initially said the problem was limited to certain postings and removed them. But the BBC has learned that the issue has been present in eBay systems since at least February 2014 and has found more listings that put customers at risk.

DoJ Seeks Authority to Bust Through Anonymization (September 19 & 22, 2014)

The US Department of Justice has proposed an amendment to Rule 41 of the Federal Rules of Criminal procedure that would pave the way for law enforcement authorities to break into computers being used by people who are hiding their identities online with anonymizing technologies like Tor.
-http://www.networkworld.com/article/2686187/microsoft-subnet/doj-wants-to-give-t
he-fbi-permission-to-hack-into-pcs-of-tor-and-vpn-users.html

-http://www.theregister.co.uk/2014/09/19/fbi_overseas_hacking_powers/
[Editor's Note (Honan): This has the hallmarks of a pending legal disaster should this amendment be passed. With the nature of anonymization networks the FBI and the US Court will not be able to guarantee the targeted computer is within US jurisdiction, leading to potential breaches of laws in other countries and indeed potential disruption of law enforcement efforts in other countries. It could also further deepen the distrust many non-US corporations and citizens have regarding excessive US government surveillance. ]

Russian Police Arrest Two in Connection with Android Malware (September 19, 2014)

Police in Russia have arrested two people in connection with malware that infected Android mobile devices through deceptive MMS messages. The messages appeared to be 'romantic" in nature, but when recipients clicked on a provided link, their phones were infected with malware that steals money from bank accounts linked to the devices.

HealthCare.gov Website Getting Security Fixes (September 18, 2014)

At a September 18 congressional hearing, Marilyn Tavenner, administrator for the Centers for Medicare and Medicaid Services (CMS) said her agency will implement 28 recommended actions to improve the security of the HealthCare.gov website before the next open enrolment period begins on November 15. Six of the actions are executive; the other 22 are technical. The Government Accountability Office (GAO) made the recommendations in a September 16 report.

Next Android Release Will Encrypt Data By Default (September 18 & 21, 2014)

Google says that the next version of its Android mobile operating system, due to be released before the end of 2014, will encrypt data by default. Android L's activation features will automatically encrypt data. (Encryption has been available and optional on Android devices since 2011.) The announcement comes as Apple releases iOS 8, the newest version of its mobile operating system, which also has enhanced security. One notable difference between the operating systems is that while most iOS users will update their devices within the next few weeks, Android users must wait for manufacturers to make the updates available.
