--Experts: Blockchain Does Not Ensure Secure Voting

(August 12, 2019)

Thirty-two US states allow some sort of online voting for some voters - often this is for members of the military and their families who are living overseas to cast absentee ballots. Some US states have launched blockchain-based mobile voting pilots. Security experts have expressed concerns that using blockchain for mobile voting spells trouble. Concerns raised include the fact that using blockchain assumes the device from which someone is casting a vote contains no malware. Experts have criticized Voatz, the company that provided the technology used in three blockchain-based mobile voting pilots, for not providing a "detailed technical description" of the technology it uses, noting that the technology has not been federally certified.       


[Editor Comments]


[Pescatore] Much of the real world is past the point of believing that adding the term "blockchain" implies anything about security. Most state governments are not able to judge the security level of election products, which is why the Help America Vote Act of 2002 established a framework for certification of voting products - there are dozens of systems on the certified list. While certification does not equal security, it should be the minimal requirement for any voting system to be considered.


[Murray] One can appreciate the use of blockchain to protect the recorded ballot from late change. It is harder to imagine how it might be used to ensure that the record correctly reflects the intent of the voter.

--A Plan to Improve Security for Local Election Offices in Wisconsin

(August 12, 2019)

According to a document from the Election Security Lead for the Wisconsin Elections Commission, local clerks in the state of Wisconsin are accessing the state's voter registration and election management system from computers that are running on operating systems that are no longer supported or for which support is soon to be discontinued, including Windows XP and Windows 7. The document proposes purchasing loaner computers that will be available to the small jurisdictions as well as hiring a new employee to provide technical support to the clerks. Wisconsin elections are supervised at the local level; some villages have fewer than 50 voters; others in urban areas have as many as 300,000.


[Editor Comments]


[Pescatore] The HAVA legislation provided states $380M in 2018 to address voting system security issues and all 50 states have received funds from it. Wisconsin's approach to managing elections at such a low level makes their job much harder.



[Neely] Funding for replacement systems as well as technical resources to help deploy them are two of the big barriers for phasing out old operating systems. Raising the bar on the endpoint by updating to current operating systems and applications should make them more resistant to attack, but attention also needs to be paid to protecting the centralized systems to insulate them from risks of unsecure endpoints.



[Murray] The integrity of the database servers should not rely on the integrity of the clients. That said, providing secure clients is cheap enough.

--More iNSYNQ Ransomware Attack Details

(August 9, 2019)

More information has emerged about the vector of infection behind the ransomware attack against QuickBooks cloud host iNSYNQ. The attackers appear to have initially gained access to the company's network through a phishing email. The attackers then spent a week and a half scoping out the terrain. iNSYNQ took its network offline on July 16. The company did not pay the ransom and is still working to restore customer access to files. During a virtual "town hall" meeting, iNSYNQ's CEO said that the company had restored access to more than 90 percent of customer files as of August 2.

 

[Editor Comments]


[Murray] The community continues to be vulnerable to enterprise-wide compromises through the compromise of one user. This is not acceptable. It results in part from flat enterprise networks. While I prefer end-2-end application layer encryption, at a minimum, desktops doing e-mail and browsing should be on a network segment isolated from infrastructure and mission critical applications.

--DEF CON Aviation Hacking Village

(August 12, 2019)

For the first time, DEF CON had an an aviation "hacking village" much like the voting systems villages that have been at the conferences since 2017. The US Air Force (USAF) was present, scouting for aviation-focused cybersecurity talent.  


[Editor Comments]


[Neely] What is needed is not only people (hunters) with the skills to find weaknesses in systems, but also those with the needed skills to secure them, which may not be the same people. Additionally, when considering weaknesses in aviation systems, consideration has to be given to the degree of redundancy and the pilot's ability to make decisions from multiple sources and override erroneous input.

--DEF CON Panel Discusses Role of Congress in National Cybersecurity

(August 12, 2019)

Speaking on a panel at DEF CON last week, US Representative Ted Lieu (D-California) told the audience that the US is not prepared to handle a cyberattack that targets multiple sectors. Lieu also said that "a single point of contact," rather than having cybersecurity responsibilities spread out over different agencies and bureaus, "would make things easier" when responding to a cyberattack.

--Australian Cyber Security Centre Issues BlueKeep Warning

(August 12, 2019)

The Australian Cyber Security Centre (ACSC) is urging businesses running older versions of Microsoft Windows to apply patches against possible BlueKeep vulnerability exploits. An exploit for the flaw has been disclosed to Metasploit. The head of the ACSC believes as many as 50,000 organizations, including some government agencies and critical infrastructure operators, are running vulnerable versions of Windows.


[Editor Comments]


[Neely] Key here is that there is now a disclosed exploit for BlueKeep. Previously reports of reverse engineering the Microsoft patch included keeping the needed exploit under wraps. The mitigation remains to apply the patch, which may require a reboot, and remove internet accessible RDP where not essential.

--Coinbase Cyberattack Began with Sophisticated Phishing Scheme

(August 8 & 9, 2019)

An incident report posted by Coinbase's CISO regarding an attack against the cryptocurrency exchange discloses that the attack began with a phishing campaign launched at the end of May. The phishing messages appeared to come from a legitimate domain. Some of the emails contained links that ultimately exploited a pair of then-unpatched Firefox vulnerabilities. Coinbase Security detected and blocked the attack.

--US Government to Establish Anonymous Vulnerability Reporting Portal

(August 9, 2019)

The US federal government plans to establish a system that will let people report vulnerabilities securely and anonymously. DEF CON will host the SecureDrop servers for the program. SecureDrop is open source software that some organizations use to receive anonymous tips. The vulnerability reports will go to the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA), which will share the information.


[Editor Comments]


[Pescatore] This approach makes sense for encouraging reporting of vulnerabilities found in US Government systems, but not for general reporting of software vulnerabilities or vulnerabilities found in private industry systems. Direct reporting to vendors (or through the managed bug bounty programs many of them have), or reporting to ISACs is already widely done and already works well. Adding another stop along the way will not add any value - where value is measured by reducing the time any vulnerability goes unfixed.


[Neely] This reporting solution aligns with plans to have CISA distribute more threat information to the private sector. It is not clear how this reporting mechanism meshes with existing reporting or bug bounty efforts already in place without introducing delays or reduction in fidelity of the reported flaws.

--Moody's: Emergency Declaration Improved Recovery from Cyberattack

(August 8, 2019)

A report from Moody's Investor Service says that when states declare emergencies in the wake of a cyberattack, there is a greater likelihood of recovery. The report looked closely at the state of Louisiana, where the governor declared an emergency in the wake of ransomware attacks against several school districts. The declaration gave the districts access to resources that would not otherwise have been available, including assistance from the Louisiana National Guard, State Police, and the Office of Technology Services.


[Editor Comments]


[Pescatore] This article implies they have only two data points to work from, so I can't see how it could have any meaningful data. A big issue is that by the time a governor can declare an emergency around ransomware (or most cyberattacks, in general) it is already too late to avoid damage. More resources should surely reduce recovery time but imagine if those resources were spent on assuring basic security hygiene *before* the ransomware hit. As far as I can tell, right now only 13 states are working with the National Governors Association to do so. In July NGA announced that Louisiana was one of 7 states that NGA resources will be supplied to "...develop action plans to advance and refine key priorities in cybersecurity." Maybe they will *not* need to declare as many cybersecurity emergencies in the future.


[Neely] Emergency declarations do allow for additional resources which will not be ordinarily available otherwise. Even so, success depends on having an updated cyber response plan for optimal application of those resources as well as identification of which resources are needed and available irrespective of the emergency declaration.
