TOP OF THE NEWS
More than 70 Percent of SSL Sites Still Vulnerable to BEAST Attack (October 18, 2012)More than a year after the disclosure of a security flaw in SSL/TLS, 71 percent of SSL sites still have not taken steps to mitigate the vulnerability. The attack, known as BEAST (Browser Exploit Against SSL/TLS) can be used to decrypt cookies that are used by websites to restrict access to accounts. Of the 179,000 websites examined, 127,000 remained vulnerable to the BEAST attack.
Experts Say Medical Equipment Running Outdated Software Enables Attacks (October 17, 2012)Experts in both the health and security fields say that malware has been found on medical technology devices. The issue was raised last week at a National Institute of Standards and Technology (NIST) Information Security and Privacy Advisory Board panel discussion in Washington, DC. The chief information security officer at Beth Israel Deaconess Medical center in Boston said that his facility has more than 650 pieces of equipment running older versions of Windows. The reason the devices have not been updated is that doing so could risk their compliance status with US Food and Drug Administration (FDA) regulations. FDA approval focuses on safety; cyberthreats are not taken into consideration. The infections could cause the devices to fail to record and track patient data.
[Editor's Note (Assante): The acknowledgement that information technology, where present, is a primary component of medical diagnostic equipment and medical devices is long over due. I have spent enough time in CT scanners to be concerned if the system was not properly calibrated. Letting the software and operating systems go unmanaged should be the same as having a machine or device fall outside of operating specifications.
(Murray): Using Windows to implement
application machines unnecessarily increases both the potential for accidental failure and the attack surface that can be exploited by rogues.
(Pesactore): Argh - this myth that medical equipment can't be patched without requiring full FDA re-certification has been nonsense for years! In January 2005, the FDA issued Guidance for Industry 1553, which states, "It is possible, but unlikely, that a software patch will need a new 510(k) submission." Later, the same document states, "In most cases, therefore, you would not need to report a cybersecurity patch under 21 CFR Part 806 so long as you have evaluated the change and recorded the correction in your records." So, please, please - don't let the equipment vendors con you.]
ISPs Will Start Anti-Piracy Alert System Next Month (October 16 & 17, 2012)In the next few weeks, US Internet service providers (ISPs) will start to implement an alert system to notify users whose accounts are being used to share copyrighted material in violation of US law. The plan, which is being overseen by the Center for Copyright Information (CCI), calls for ISPs to send alerts to the account holders. If there is no response to a first set of alerts, ISPs may take other steps to gain users' attention, such as slowing their Internet speeds or directing them to online tutorials about digital copyright. The goal of the plan is to educate and inform users, saving punishment as a last resort for users who do not respond to alerts and do not stop the illegal activity.
[Editor's Note (Pescatore): I'd like to see similar action against users who are running botnet command and control sites... ]

Apple Getting Tough on Java (October 18, 2012)Apple has released updates for Java 6 on Mac OS X 10.6.8, 10.7, and 10.8, bringing Java for Mac OS X in line with Oracle's most recent Java update. However, the Apple update removes old versions of Java browser plug-ins from browsers that run on Mac OS X. This means that Mac users who want to run Java on their computers will need to download the software from Oracle. On computers running Snow Leopard, users who have not installed Java for Mac OS X 10.6 update 9 will have their browsers reconfigured not to run Java applets by default. Once the update for Lion and Mountain Lion is in place, users who visit websites that require Java will see the "Missing Plug-in" message and can download Java 7 from Oracle. Apple has been aiming to eliminate certain browser plug-ins - most notably Flash and Java - that have been proven vectors of attack. Apple stopped bundling Java with its operating systems when it introduced Lion in 2011. Removed on Safari and other browsers running on the Mac OS X platform. Oracle has issued a batch of security fixes for its products, including Java. The Java update addresses at least 30 vulnerabilities.
HSBC Hit With DDoS Attack (October 18, 2012)UK-based bank HSBC has been targeted in a distributed denial-of-service (DDoS) attack. The bank says that while customers found themselves unable to log in to their accounts, no customer data were affected by the attack. HSBC is "cooperating with relevant authorities." As of Thursday evening, some sites were once again accessible.
Review Finds No Evidence of Huawei Espionage (October 17 & 18, 2012)A review of security risks posed by companies that supply telecommunications equipment to US organizations found no evidence that Huawei had conducted espionage for China. In a recently released congressional report, US legislators were openly critical of Huawei and ZTE for not being more forthcoming about their relationships with the Chinese government. The report said that Huawei and ZTE products "cannot be trusted to be free of foreign state influence and thus pose a security threat to the US and to
systems." However, the review, which was ordered by the White House, did find evidence that using equipment from Huawei could pose risks because it contains exploitable vulnerabilities. What is not clear is whether the flaws were intentionally built into the equipment or if they are the result of poor coding practices. Clouding the issue, a White House National Security Council spokesperson has said, "The White House has not conducted any classified inquiry that resulted in clearing any telecom equipment supplier." Huawei is feeling pressure from other countries as well. The Australian federal government has barred Huawei from bidding on the country's National Broadband Network, but has not given reasons for the decision beyond saying that it acted on advice from the Australian Security Intelligence Organisation (ASIO).
[Editor's Note (Honan): Vulnerabilities exist in all systems, especially in the modern global economy where parts and materials are subcontracted to many third parties. Before implementing any equipment or software you should conduct a proper risk assessment and controls put in place to continuously monitor it. This is the approach the UK has taken with Huawei since 2001
Adobe Reader and Acrobat XI Offer Enhanced Security Features (October 17 & 18, 2012)Adobe has released updated versions of Reader and Acrobat with improved security features, including enhanced sandboxing. The sandbox feature, which was introduced in Adobe Reader X, has made it more difficult for hackers to attack the products as it restricts read-only activities as well as write operations. The new versions of Reader and Acrobat also offer PDF whitelisting, force Address Space Layout Randomization (ASLR), and Elliptic Curve Cryptography for digital signatures.
Pirate Bay Moves to the Cloud (October 17, 2012)The Pirate Bay has moved to the cloud to evade takedown attempts. Instead of relying on physical servers, the filesharing site now operates through virtual machines on several different cloud services in two different countries. After Swedish police raided hosting company PRQ earlier this month, a number of torrent sites went dark; Pirate Bay had stopped using PRQ for hosting services before the raid.
Pacemakers Can be Hacked to Deliver Deadly Shock (October 17, 2012)At a security conference in Melbourne, Australia, a researcher demonstrated how a pacemaker could be remotely instructed to deliver an 830-volt shock. Someone armed with a laptop from up to 50 feet away could command the device to administer the fatal voltage. The problem lies with the wireless transmitter programming. It was not complicated to get the devices to reveal their serial and model numbers, which would allow an attacker access to reprogram transmitted firmware and ultimately, reprogram the implanted device.
Kaspersky Developing Secure OS for Industrial Control Systems and Medical Appliances (October 16 & 17, 2012)Kaspersky Lab is developing a secure operating system that it says will provide added protection against threats like Stuxnet. The OS is being designed specifically for companies that are responsible for elements of critical infrastructure so they can run their industrial control systems more securely. CEO Eugene Kaspersky said that ideally, to secure industrial control systems (ICS), all ICS software would need to be rewritten from scratch, incorporating the best security technology. Because that would require vast amounts of time and money, a secure OS is the next best option.
Study Says Filesharers Buy More Music Online (October 15 & 17, 2012)According to a study from The American Assembly, people who engage in filesharing are more likely to buy music online than non-filesharers. While the music collections of filesharers are larger than those of non-filesharers, largely due to free downloading and copying music from friends and family, filesharers have a rate of online music purchase that outstrips that of non-filesharers by 30 percent.
McKinnon Will Not be Extradited (October 16, 2012)The UK will not extradite Gary McKinnon to the US where he would face charges for allegedly breaking into computer systems at the Pentagon and NASA in 2001 and 2002. UK home secretary Theresa May has blocked the extradition due to human rights concerns. McKinnon, who has Asperger's Syndrome and depression, could become suicidal if he were sent to the US to face trial. UK prosecutors could potentially bring charges against him domestically. McKinnon's allegedly took actions that resulted in the "shut down
the entire US Army's Military District of Washington network ... for 24 hours," and damages allegedly ran to US $700,000. US officials have expressed disappointment over the decision.
