TOP OF THE NEWS
Some Countries' Governments Have Unfettered Access to Vodafone Data (June 6, 2014)In a transparency report released last week, international telecommunications company Vodafone said that several national governments have direct access to communications that travel through the company's network. In most countries, governments need warrants to access the information, but in six unnamed countries, law enforcement has direct access to the data. Vodafone received data requests from 29 countries during the yearlong period covered by the report, but did not provide a breakdown by country, in part because laws in some countries prohibit the disclosure of such surveillance.
FAA Orders Boeing to Implement Cyber Security Measures to Protect 737s (June 6, 2014)The US Federal Aviation Administration has ordered aircraft manufacturer Boeing to make changes to technology on its late-model 737 planes to protect them from cyber attacks. The order specifically notes concern about "a novel or unusual design feature associated with the passenger service computer systems to the airplane systems and data networks" that could be exploited to cause "intentional or unintentional destruction, disruption, degradation, or exploitation of data, systems and networks critical to the safety and maintenance of the airplane." A Boeing spokesperson says the order addresses actions that the company had already undertaken or plans to implement.
Bank Appreciative of Canadian Teens' Identification of ATM Weakness (June 8 & 9, 2014)Two Canadian teenagers who found an ATM operator's manual online tried using the information they found on a supermarket ATM over their school lunch hour. The ninth graders were surprised to find that a common default password provided them operator access to the machine. They boys went straight to a local branch of the Bank of Montreal, where at first staff members did not believe their claims. The two asked permission to go back and get proof; documentation printouts convinced employees that their claims were serious. The bank manager provided the boys with a note to their school, excusing their lateness "due to assisting BMO with security."
[Editor's Note (Northcutt): Ah yeah, the ol default-password-on-the-money-dispensing-machine trick. One day someone is going to create a list of default passwords and we will be forced to change them. Oh yeah, they already have:

THE REST OF THE WEEK'S NEWS
Russian Authorities Arrest Two Suspected of Apple Ransomware Attack (June 10, 2014)Authorities in Russia have arrested two people in connection with a spate of attacks that held Apple devices for ransom. The suspects were nabbed when they withdrew a ransom payment from an ATM. People in Russia were being targeted in similar attacks shortly before news of similar Australian attacks emerged last month. The suspects allegedly harvested iCloud login credentials through a phishing site and used the access to lock the iPhones, iPads, and Mac computers through an iCloud feature that lets people locate their devices.
Cyber Security Solutions Approached From Multi-Disciplinary Perspective (June 9, 2014)Army Col. Gregory Conti director of Army Cyber Institute at US Military Academy West Point, is taking a multidisciplinary approach to protecting cyberspace for the military, the government, and the country. It can be unclear who has authority in various cyber attack situations: the military, the government, or industry. Conti says that coming to "real solutions
[will require ]
a combination of many disciplines."
Dropbox Phishing Scheme Uses Ransomware to Extract Bitcoin Payments (June 9, 2014)A phishing scheme involving Dropbox infected as many as 350,000 computers with ransomware that has earned those running the operation more than US $70,000 in Bitcoins. The malware, known as CryptoWall, spreads through email messages directing recipients to Dropbox; if they download the indicated ZIP file and run the executable, the malware is loaded onto their machines. Users then receive messages saying that their files have been encrypted and demanding a Bitcoin ransom of US $500, which increases to US $1,000 if it is not paid within a few days.
[Editor's Note (Murray): Of course, any file server would do as well as Dropbox. On the other hand, Dropbox adds spice to an otherwise "Dummy takes bait and gets owned" story. ]
New Hampshire Town Will Not Pay Cryptowall Ransom (June 7, 2014)Durham, New Hampshire Town Manager Todd Selig said that the town has no intention of paying ransom to decrypt files taken hostage by Cryptowall malware. The police department system was reportedly infected after an officer opened what looked like a legitimate attachment. Cisco's Cloud Web Security service is blocking access to nearly 100 domains that appear linked to the Cryptowall malware. The attacks blocked by this action are being launched by advertisements on popular websites that lead site visitors to malware.
[Editor's Note (Murray): The success of such attacks requires that the perpetrator have "write" access to the data. Decades ago, when Donn Parker speculated about this attack, I thought it unlikely that anyone would have the necessary privileges. Security is hard and intuition does not serve well. The attack also requires that there be no backup, or that the perpetrator also has write access to it. Imagine that. In a world in which one can buy a terabyte of storage to put in one's pocket for $100, failure to have safe backup is inexcusable. ]
Android Ransomware (June 6, 2014)Ransomware targeting Android devices encrypts pictures, documents and other content on the devices. Called Android/Simplocker, the malware displays a message telling users that their device has been locked because it was used to access illegal content. Simplocker requires payment in Ukrainian currency, instructing victims to pay 260 Hryvnia (US $22) to have their files unlocked.
UK Cyber Essentials Program Encourages Companies to Apply Basic Security Controls (June 6, 2014)A new program called Cyber Essentials offers businesses in the UK the opportunity to obtain information security badges that let users know they have implemented certain security measures. The "Cyber Essentials" badge is granted to companies that have implemented five basic security controls: boundary firewalls and Internet gateways; secure configuration; access control; malware protection; and patch management. Later this year, companies will be able to achieve a "Cyber Essential Plus" badge, which is awarded based on the results of an annual independent audit. The program was developed with input from the British Standards Institution, the Information Assurance for SMEs Consortium, and the Information Security Forum and is funded by the UK government's National Cyber Security Program. The program has been criticized for being too general and the requirements for being too basic, but the program itself could prompt attention to IT security among C-level executives. It is also providing a baseline for what should be expected of all companies.
[Editor's Note (Pescatore): The wording of the UK "Cyber Essentials" is too simplistic. Anyone with a firewall, AV software, a few policies around access control and who patches within 14 days can fill out a form and get a badge. It seemed like it was written for home users, not even small businesses. Even the lowest level PCI Self-Assessment Questionnaire requires higher levels of protection.
(Honan): While the program may be basic it should be seen as a welcome development. Similarly to having to be tax compliant to be able to sell to UK government bodies, companies will also know have to demonstrate they take cyber security seriously. Over time this should hopefully spread further down the supply chain. ]
Report Says Financial Institutions Need to Share Threat Intelligence (June 6, 2014)The 2014 Annual Report of the US's Financial Stability Oversight Council (FSOC) says that financial institutions should make it a priority to share cyber intelligence. The report also calls on the Treasury Department to make sure that financial institutions and related and supporting organizations are implementing appropriate cyber security measures. FSOC was established in 2010 to "identify risks to the financial stability of the US ...
to respond to emerging threats."
[Editor's Note (Honan): The Bank of England has recently launched their CBEST initiative to set up a programme of work to improve and test resilience of the UK financial infrastructure to cyber-attack. They have produced a number of excellent guidelines on various areas including a document on "Defining the qualities that participants should consider when selecting a threat intelligence provider"
I recommend it to anyone responsible for information security. ]
GAO Report Calls on DHS to Address Port Security (June 6, 2014)According to a report from the US General Accounting Office, The Department of Homeland Security (DHS) needs to do more to protect IT systems at the country's ports. The report, "Maritime Critical Infrastructure Protection: DHS Needs to Better Address Port Cybersecurity," found that maritime security plans did not address cyber threats.
[Editor's Note (Murray): IT is used to operate all our infrastructure. It is a vulnerability shared by all of our critical infrastructure components. Those of us who understand IT best tend to focus on it while the managers of transportation, finance or other components tend to focus on those before IT. We should not be surprised that those responsible for "port security" worry first about ships and cargo. ]
SmartTV Flaw (June 6 & 9, 2014)A vulnerability in many Smart TVs could be exploited to gain access to set owners' home networks. Called the Red Button attack because of its exploitation of the interactive features of the televisions normally accessed by a red button on the remote, it is basically a man-in-the-middle attack. It works by hiding malicious code in signals broadcast to the televisions. Compromised televisions could be used to post messages to social media accounts, launch attacks, and seek out other network-connected devices in homes. The attack would be hard to detect and hard to stop. It affects all Smart TVs that are compatible with the HbbTV (hybrid broadcast-broadband) standard, which is widely used in Europe and is making its way into the US market.
[Editor's Note (Murray): Not so much a "flaw" as a feature. Flaws are easier to fix than features. That said, not all vulnerabilities are problems, not all problems are the same size. The ratio of the cost of this attack to the value of its success is likely to be higher than that of alternatives for quite some time. ]
