-US OMB and CIO Council Open Cyber Reskilling Pathway for Federal Employees

(November 30, 2018)

The US Office of Management and Budget (OMB), along with the Department of Education and the CIO Council, is launching the Federal Cyber Reskilling Academy, which will train current federal employees to become cyber defense analysts. The program is open to any federal employee who does not currently work in the cyber or IT fields. Applications for the program opened on November 30, 2018; they close on January 11, 2019. In mid-January, applicants will be sent links to online critical thinking and problem-solving skills assessments; the members of the first cohort will be chosen starting in late February 2019. The three-month training program will begin on March 11.


[Editor Comments]


[Neely] While applicants will need to pass the screening processes, critical thinking/problem solving, the reward is top quality training and certification. Federal employees with any interest in Cyber Security should apply.


[Honan] Too often people see a career in cybersecurity as a quick way to earn money due to the skills shortage. However, a good cybersecurity professional is not just technically proficient but needs skills such as problem solving and critical thinking. I think this is a great move.


[Paller] The aptitude and capabilities identified in the Federal Reskilling Programs Aptitude Test are valuable for other high-paid careers such as advanced software development. In the largest global survey of employers and employees of software developers, specific programming skills were essential, but proven problem-solving skills were ranked by employers as nearly twice as important as a core competency.

--Marriott Starwood Breach

(November 30 & December 1, 2018)

The intrusion that initiated the Marriott Starwood data breach occurred in 2014. The breach compromised personal information of as many as 500 million customers. The affected data include names, birth dates, information about trips and reservations, and passport numbers. The breach was detected in early September 2018, but its scope was not determined until mid-November, when investigators found an encrypted version of the entire Starwood reservation database on the web. 


[Editor Comments]


[Ullrich] First of all, it would be nice if the company Marriott hired for the web monitoring service cared enough about information security to allow passwords longer than 15 characters (which actually likely indicates that passwords are not hashed). Secondly: If you are affected by a breach like this (who isnt?), think beyond the hype. 500 Million lost records is a large number. But for most of us, this is luckily not the breach to worry about. Most of us just lost payment card data and maybe data like usernames and passwords. I do absolutely not care about how many times my credit card data is stolen each year. Credit card companies/banks dont care, and they bear the financial burden. If they would care, they would fix it. As for my Marriott/SPG password: Not using the same password at any other sites makes this a non-event for me. Probably the most sensitive piece of information lost in this case is passport data (if you had that information stored with Marriott). If would be nice for Marriott to list exactly what information they believe was stolen for a particular account. But again, that would require them to care.


[Neely] When you take remediation steps, address both your Marriott and SPG accounts, if you havent combined them. Given the number of hotel chains under the Marriott/Starwood brand, dont assume you havent stayed in one of their properties; proactively check.

--China Intensifies Cyberespionage Targeting US Organizations

(November 29, 2018)

China has stepped up its cyberespionage efforts to obtain technological information from the US. Three years ago, the US and China reached an agreement that ostensibly ended Chinas practice of stealing intellectual property from US organizations. The attacks did decrease for about a year and a half, but began again shortly after the current administration took office.

--US Senators Introduce Global Electoral Exchange Act

(November 30 & December 3, 2018)

US senators have introduced the Global Electoral Exchange Act, a bill that would establish a State Department-based program to share election security information with other countries. Under the program, the State Department would offer grants to US non-profit groups involved in election security issues so that they can share information with similar organizations in other countries. The program would also provide opportunities for US elections officials to visit other countries to observe their elections security practices, and for foreign elections officials to visit the US for the same purpose. The House unanimously passed similar legislation earlier this year.

--House Passes SMART IoT Act

(November 29, 2018)

The House of Representatives has passed the SMART IoT Act, which direct[s] the Secretary of Commerce to conduct a study and submit to Congress a report on the state of the internet-connected devices industry in the United States. The bill now goes to the Senate, with just two weeks left in the legislative session. If enacted, the Department of Commerce would have one year to provide Congress with a report that includes a survey of the internet-connected devices industry through outreach to participating entities as well as information about agencies with jurisdiction over the identified entities; and existing related regulations and standards. The report would be delivered one year after the bill is enacted.

--Citrix Changes ShareFile Password Policy

(December 4, 2018)

Over the weekend, users of Citrixs Sharefile service were forced to change their passwords. Citrix says that the forced password reset is not due to a breach, but an effort to stay ahead of hackers who may try stolen access credentials on other accounts. Citrix says that users will be required to reset their passwords at regularly scheduled intervals.


[Editor Comments]


[Pescatore, Murray, and Neely] It is pretty much standard advice to change compromised passwords on any other sites where you are using them, so Citrix doing a forced reset has a certain logic to it. But, we know from years of past experience that forcing quarterly password resets generally results in *lower* security and we know that large scale breaches are occurring at least quarterly, so I dont think this ends up increasing security. Id much, much rather see Citrix use these events as opportunities to convince users to migrate to Sharefiles Two Step Verification and see Citrix work to make two-factor authentication work with corporate logins and custom home pages.


[Ullrich] Forcing users to periodically change their passwords has been shown to be ineffective and often counterproductive. However, accounts should be locked if the password was reused and leaked in a breach of a different organization, or if the account was idle for an extended time. For the first case, Troy Hunt does an excellent job in providing data to allow organizations to recognize if a password was shared. The second case very much depends on the organizations business, but disabling accounts that have not been used, and forcing users to use a reset procedure to enabling them, will prevent some credential stuffing attacks. Just make sure that the reset procedure is implemented correctly.


[Honan] Most up to date guidance is for users not to regularly change passwords as this leads to password reuse and variations of the same password (see the UKs National Cyber Security Centres password guidance https://www.ncsc.gov.uk/guidance/password-guidance-simplifying-your-approach: Password Guidance: Simplifying Your Approach) Cloud providers, like Citrix, should look to enforcing Multi Step and/or Multi Factor authentication for their users.

--Malicious Apple Fitness Apps Use TouchID to Trick Users into Approving Exorbitant Charges

(December 3, 2018)

Apple has pulled several sketchy iOS fitness apps from the App Store after they were found to be tricking users into okaying US $120 payments using the companys TouchID fingerprint recognition feature. The Fitness Balance app, Calories Tracker app, and Heart Rate Monitor behaved like reasonable fitness apps, but they were found to be using a pop-up ruse to trick users into authorizing in-app payments. Users who have had funds stolen can contact Apple for a refund.

--Windows Active Directory Setting Found to be Effective Against NotPetya-Like Worm

(December 3, 2018)

UK security firm NCC Group was asked by a customer to create a less lethal version of the NotPetya malware and release it onto the customers network so they could learn how to defend their systems from similarly-destructive malware. During the exercise, NCC discovered that the 'Account is sensitive and cannot be delegated' Windows Active Directory setting, when applied to domain administrator accounts, hindered the worms efforts to spread.


[Editor Comments]


[Honan] What is just as effective is restricting access to the Domain Administrator account, allocating dedicated domain admin accounts for administrators, and removing user accounts from the Domain Administrator groups. Also using Microsoft Local Administrator Password Solution to manage local administrator access on PCs and laptops is also very effective. https://www.microsoft.com/en-ca/download/details.aspx?id=46899

--Signet Jewelers Fixes Purchase Data Exposure Hole on Websites

(December 3, 2018)

The parent company of jewelry retailers Jared and Kay Jewelers has fixed a vulnerability on their websites that could have been exploited to expose the order information of all online customers. The company initially addressed the issue only partially, protecting all future purchases. It later fixed the problem so that past order information was not exposed.


[Editor Comments]


[Neely] The OWASP Top Ten A2 addresses weak or broken authentication and session management. In short, a reminder that creating your own algorithm for generating authentication or session tokens can lead to their being easily guessed/manipulated. Additionally, when obtaining a bug report be sure to capture the entire scope of the flaw so you dont find the gaps the hard way. Kudos to Brandon Sheehy for escalating the issue to insure the bug was fully fixed.
