 --Russian Charged Over Election Meddling

(October 19 & 22, 2018)

The US Department of Justice (DOJ) has charged Elena Alekseevna Khusyaynova with conspiracy to defraud the United States for allegedly interfering with the US political system, including the upcoming 2018 midterm elections. Khusyaynova allegedly managed the finances for a group financed by a Russian oligarch and involved in foreign influence activities.

--Super Micro Will Review its Hardware for Malicious Chips Despite Lack of Evidence

(October 22, 2018)

In an effort to debunk allegations made in a recent Bloomberg story that Chinese spies had placed malicious chips in some of its products, Super Micro Computer says it will examine its hardware. No one has shown us a motherboard containing any unauthorized hardware chip, we are not aware of any such unauthorized chip, and no government agency has alerted us to the existence of any unauthorized chip, company CEO Charles Liang wrote last week in a letter to customers. Despite the lack of any proof that a malicious hardware chip exists, we are undertaking a complicated and time-consuming review to further address the article.


[Editor Comments]


[Pescatore] Whether or not Super Micros boards were tampered with, there are plenty of examples of such hardware tampering being done by Chinese, Russian and US government agencies. When I worked for the US Secret Services in the 1980s, we were still dealing with the discovery that IBM Selectric Typewriters sent out for repair by the US Embassy in Moscow and consulate in Leningrad had been tampered with and provided monitoring capabilities that the USSR exploited for 8 years!! Supply chain security is a complex targetthe first step is making sure the CFO and Chief Legal Counsel understand the risks and that procurement processes are reviews to find gaps.


[Neely] Make sure you and your suppliers have a plan for the discovery and resolution of any non-genuine devices.


[Murray] The supply chain constitutes a troubling vulnerability; among other things it makes us vulnerable to sleeper agents. However, until there is clear evidence of exploitation, it does not constitute a measurable risk, certainly not one that ranks with porous software and social engineering. These are sufficient to demonstrate that our current permissive policies and strategies are not working. More restrictive policies and strategies would reduce our cost of security, e.g. patching, and our cost of losses, breaches and tighten the supply chain.

 --Critical TCP/IP Flaws in FreeRTOS

(October 22, 2018)

Critical security flaws in FreeRTOS, an operating system kernel used in many Internet-connected devices and embedded electronics, could be exploited to take control of vulnerable devices. Amazon Web Services (AWS) assumed stewardship of the FreeRTOS kernel last November.


[Editor Comments]


[Ullrich] Organizations have 30 days to patch this before Zimperium will release details. A lot of the patches have to come from vendors using an affected OS. Note that some of the vulnerabilities affect not only the Amazon-maintained FreeRTOS, but may also affect OpenRTOS and SafeRTOS (if the vulnerable TCP/IP components are installed). A patch will likely have to arrive from the device manufacturer.

--Healthcare.gov Breach Exposed Personal Information of 75,000 Users

(October 21, 2018)

A breach of the Healthcare.gov sign-up system compromised personal information of 75,000 users. Healthcare.gov hosts the Federally Facilitated Exchanges (FFE) that agents and brokers use to sign people up for Affordable Care Act (ACA) health plans. The FFE system is managed by the Centers for Medicare & Medicaid Services (CMS), which issued a press release about the incident on October 19. The press release noted that the incident will not negatively affect open enrollment. The accounts associated with the activity that alerted CMS to the breach have been deactivated.


[Editor Comments]


[Ullrich] You can consider this a success story in detecting and mitigating unauthorized access by an authenticated user. According to the press release, the leak happened when authorized agent and broker accounts accessed the data. It isnt clear whether the particular user was acting malicious, exploiting a vulnerability, or if these users account was compromised.

--Big Tech and Government Cybersecurity

(October 22, 2018)

The White House is planning to meet with Amazon, Google, IBM, and Microsoft to try and hammer out arrangements that would encourage some of their employees to temporarily take jobs with the federal government to help modernize its approach to cybersecurity. Because the companies are some of the governments largest vendors, care will need to be taken so that employees who elect to work for federal agencies do not experience a conflict of interest. US Director of National Intelligence Dan Coats has called out tech companies over the incongruity of their reluctance to work with the US government and their willingness to work with foreign entities like China.

--Australian Intel Director Defends Assistance and Access Bill

(October 22, 2018)

Duncan Lewis, Director General of Security at the Australian Security Intelligence Organization (ASIO), defended the controversial proposed Assistance and Access Bill that would give Australian intelligence agencies the authority to request and in some cases demand access to encrypted communications. Lewis said that the bill does not allow for persistent monitoring or mass surveillance. The bill lays out three levels of access assistance. Technical Assistance Notices would compel providers to provide decrypted communications through means they already have available; Technical Capability Notices would compel providers to build technology to allow intelligence to access encrypted communications; and Technical Assistance Requests would ask providers to help voluntarily. The content sought with Technical Assistance Requests would not be constrained by the same rules that apply to the Notices, and the requests would not be included in annual audit reports.

--FDA Draft Premarket Guidance for Medical Device Manufacturers Proposes Cybersecurity Bill of Materials

(October 19, 2018)

A US Food and Drug Administration (FDA) draft of premarket guidance for medical device manufacturers proposes preparing a cybersecurity bill of materials that alerts users to hardware and software components used in the devices. The draft guidance also addresses general principles and risk assessment, and trustworthy device design though the use of the National Institute of Standards and Technology (NIST) Framework.


[Editor Comments]


[Pescatore] Im going to go cynical here: the FDA has been putting out guidance on cybersecurity for medical devices for years and the security quality of the devices sold hasnt really changed. Most of the guidance just requires more documentation vs. more securityand the FDA never seems to take any real enforcement action. I think it is necessary for the Healthcare ISAC or other health care system buyers group together to take joint action to drive security testing requirements into all procurements of medical devices and systems.


[Neely] Creating frameworks and guidelines for securing medical devices is a great step forward. This guidance seems to lack requirements to actually implement this guidance.

--Tools Leaked by Shadow Brokers Used in Attacks

(October 19, 2018)

Cyber criminals are using NSA hacking tools leaked last year by Shadow Brokers to target systems at organizations in aerospace, nuclear energy and other industries in Russia, Iran, and Egypt, according to Kaspersky Lab researchers. The tools used in the attacks are the Dark Pulsar backdoor and the FuzzBunch and DanderSpritz toolkits.   


[Editor Comments]


[Williams]  The nuclear and aerospace industries are not typical cybercrime targets. Their targeting implies that nation states are reusing the NSA tools.

--OpenBSD 6.4 Disables Audio Recording By Default, Adds Mitigations for Spectre and Other CPU-Related Attacks

(October 19, 2018)

OpenBSD 6.4 was released on Thursday, October 18. The newest version of the operating system disables audio recording by default; users who want to switch it on can flip a kernel flag. OpenBSD 6.4 also includes mitigations for Spectre v2, SpectreRSB, L1TF, and Lazy FPU attacks.

--SEC Report Suggests Insufficient Internal Accounting Controls Could Violate Federal Law

(October 16 & 17, 2018)

Last week Tuesday, October 16, the US Securities and Exchange Commission (SEC) issued a report on an investigation into whether nine companies that had experienced cyber-related fraud had implemented sufficient internal accounting controls. The report specifically examines incidents involving business email compromise (BEC) in which the company lost at least US$1 million. The report concludes that companies that have not implemented sufficient controls could be in violation of federal law.


[Editor Comments]


[Pescatore] The report points to the 1934 Securities Exchange Act that requires companies maintain internal accounting systems that provide shareholders with reasonable assurances that the business is adequately controlled and some later regulations that require those reasonable controls around transactions in particular. Of course, the SEC hasnt and doesnt define reasonable so there really isnt much to this report as far as forcing functions to drive businesses to higher levels of email security, but the headlines are still useful in getting support for deploying DMARC and stronger authentication.

--UKs National Cyber Security Centre

(October 16 & 17, 2018)

The UKs National Cyber Security Centre (NCSC) was established two years ago as a single entity focused on protecting the countryincluding companies and private citizensfrom cyberthreats. NCSC, which is part of the Government Communications Headquarters (GCHQ), the UKs counterpart to the USs National Security Agency (NSA), manages to strip intelligence from classified threat information and push it out to businesses and the public citizens quickly. The USs approach to cybersecurity lacks this focus. The Department of Homeland Security (DHS) the FBI, and the NSA all see cyberattacks every day but cannot always notify victims. The reasons vary: DHSs responsibilities are broad; the FBI investigates incidents, but covertly; and the NSA is limited regarding its interaction with US citizens.


[Editor Comments]


[Paller] The value of the UKs more centralized management of cybersecurity became especially visible in the last year when the UK created a coordinated national effort in all UK schools to find cyber talent and develop it. DHS continues spread money to schools and grantees without first determining whether the people being trained have the natural aptitude and the tenacity to excel.

 --Youre Not Imagining It: Civilization is Flickering, Part 1

(October 22, 2018)

In Part 1 of a two-part blog post, Michael Assante notes, As our reliance on connected digital systems becomes nearly total, and as computers susceptibility to manipulation by remote others is now well established, all well-informed citizens have ample cause to be anxious about their lightsand much more. But how do we decide whether we listen to the doomsayers or those who say we should just relax, its not that bad? Assantes blog will give you a few tools to better judge for yourself which of these voices is closer to the ground truth. (Look for part two in Fridays NewsBites.)


[Editor Comments]


[Assante]  The important concept here is that focusing on responding to a breach will not be sufficient in a highly automated and hyper-connected world. Engineers and cyber professionals will need to be prepared to work much closer together in the near future.
