 --Texas Ransomware Attack Affects 23 Local Government Organizations

(August 16, 18, & 19, 2019)

On Friday, August 16, computer systems at 23 local government organizations in Texas became infected with ransomware. Evidence points to the attacks coming from "one single threat actor," according to the Texas Department of Information Resources (TDIR). Recovery efforts are being supported by both state and federal authorities.

   

[Editor Comments]

    

[Pescatore] Local government systems have sort become the "reunion" tours of most forms of malware: first the attackers go after the larger more lucrative targets, who then start to address the vulnerabilities. Then we usually see waves of the same attacks succeeding at smaller firms and then state and local agencies. That points out two things: (1) State and local agencies have staffing, funding and governance obstacles that are not being overcome and (2) State and local agencies don't seem to take advantage of advanced knowledge that those high profile attacks of last year are going to hit them this year.

--Army Cyber Units Lack Adequate Staff, Equipment, Training

(August 19, 2019)

According to a report from the Government Accountability Office (GAO), the US Army's cyber units are woefully understaffed. They also lack sufficient equipment and training. The 915th Cyber Warfare Support Battalion and the Intelligence, Cyber, Electronic Warfare and Space (IECWS) unit were established over the last two years, and more units are planned for 2020. GAO recommendations include risk assessments of staffing, equipment, and training at both existing units, and creating risk assessments for new units.  


[Editor Comments]


[Murray] Government may be an exception but most security programs that are resource-constrained are so because they have not yet learned to make effective proposals, take "no" for an answer, and regroup. "No" is far more often the answer to inadequate justification than a decision to accept risk. General management needs to learn to put resources where they want the capability to be.


[Paller] Bill Murray's comment highlights one of the great opportunities for rapid improvement of the effectiveness of cybersecurity technical leaders - learning to present cybersecurity requirements in ways that animate and persuade general managers. Fear doesn't work anymore. To give SANS Technology Institute graduate and undergraduate students a career boost by becoming effective presenters of cybersecurity requirements, we built a new course called "Secrets to Successful Cybersecurity Presentations." It covers security briefings from the first one a new employee will give to how to brief boards of directors. It will be ready around the end of the year. We hope to also make it available to all SANS alumni. The companion course, SEC402: Cybersecurity Writing: Hack the Reader, was just released.

-- Cheating On "Ethical" Hacker Exams?

(August 19, 2019)

A DoD contractor claims he and others got undue help on their ethical hacker exams. In March of 2017, the contractor they worked for, SAIC, allegedly gave them a printout the day before they took the test that contained the same questions and answers as the test. Confirmation came from a second contractor: "The first questions come on the screen, and it is exactly the same as we had in the test bank earlier. "The sequence of the questions were different, but the actual questions and the answers were identical. The options of A,B,C,D were exactly the same. Identical."

--US Gives Companies Another 90 Days to Work With Huawei

(August 19, 2019)

The US has extended the temporary license that allows US companies to sell products to Huawei. At the same time, the US added 46 companies associated with Huawei to an export blacklist. (Please note that the WSJ story is behind a paywall.)

--Updates Available for Fix Webmin Backdoor

(August 19, 2019)

A backdoor in the Webmin, the open source sysadmin task application for Unix systems, could be exploited to execute commands with root privileges. Webmin maintainers have released updated versions of Webmin (1.930) and the associated Usermin (1.780) to address the issue.  


[Murray] It is ironic that the privileged users, those over whom we most need accountability, are those most likely to use shared IDs and passwords, have excessive privileges, and have privileges that we can not successfully withdraw. All enterprises, without exception, should be using Privileged Access Management software, and have a well designed policy for its use.

--Hacker Ordered to Forfeit $480,000 in Ill-Gotten Gains

(August 19, 2019)

A UK court has sentenced Elliot Gunton to 20 months in prison; he pleaded guilty to several charges, including hacking and money laundering. Gunton has also been ordered to forfeit more than #400,000 (US $485,000) in bitcoin that he received as payment for his hacking services. Gunton has been released as the time he has already served in custody fulfills his prison sentence.

---US Customs and Border Protection IT Outage Slows Passenger Processing

(August 16, 2019)

On Friday, August 16th, US Customs and Border Protection (CBP) suffered an IT outage that caused a significant slowdown in the agency's ability to process incoming travelers, including US citizens. While CBP worked on fixing the problem, the agency reverted to manual mechanisms for processing passengers.

 

[Editor Comments]


[Murray] Face it. If a manual procedure is as fast as the automatic one, it is probably as efficient. While alternatives improve resilience, they do so at some cost, and only by plan. "A plan is not a document that one takes out and reads while sitting in the ashes. It is a capability, the ability to do something in its presence that one cannot do in its absence." --Robert H. Courtney, Jr.


[Neely] Having manual procedures to back-up IT processes when they fail is outstanding. Unfortunately, this manual system doesn't have the same throughput as the automated system. Be sure to understand the impacts on customers when failing to manual mechanisms and investigate having alternate automated systems that could kick in before a full fallback to manual processing.

--Appeals Court Allows Privacy Lawsuit Against Facebook to Proceed

(August 16, 2019)

A federal appeals court in California has ruled that a class action lawsuit against Facebook may move forward. The lawsuit alleges that Facebook's tagging feature violated an Illinois privacy law. Illinois's Biometric Identity Privacy Act (BIPA) requires all companies operating within Illinois to adhere to a strict set of privacy requirements relating to the use and collection of biometric data, including notification of collection, intended use and retention as well as written permission for that use. The lawsuit alleges that Facebook's tagging feature broke the law with its use of facial recognition technology.

 

[Editor Comments]

 

[Neely] This could be a test of the Facebook EULA where they claim rights to all content posted and end-user privacy claims about the content they share. When sharing content through someone else's service (e.g. Facebook, Twitter, LinkedIn, etc.) be aware of the privacy and ownership terms around sharing that data that you've agreed to. As a company, while much focus has been on GDPR privacy concerns of late, don't forget to consider applicable privacy regulations such as BIPA and CDPR.

--ECB Shuts Down Third-Party-Hosted Site After Malware Infection

(August 15 & 16, 2019)

The European Central Bank (ECB) has shut down one of its websites after it became infected with malware. The attacker also compromised the personal information of about 480 individuals. The affected site is ECB's Banks' Integrated Reporting Dictionary (BIRD) system, which offers members of the EU banking industry information about generating statistical and supervisory reports. The attack appears to date back to December 2018, although it was discovered more recently during regular maintenance.


[Editor Comments]


[Pescatore] Imagine if the headlines said, "Robbers Steal Millions from Bank Vault Installed By Third Party." There are definitely supply chain security complexities, as well as with the use of Software-as-a-Service but third-party hosting of web sites has now been common for more than a decade and the issues for assuring visibility and control of security are pretty straightforward.


[Neely] Third-party security can be very difficult. Irrespective of contractual obligations to maintain minimum levels of security, the data owners have an obligation to verify these controls are in place. In addition to regular reviews of these controls, include discussions with the third-party regarding forwarding event data to your SIEM for increased visibility.

--Proposal Would Limit Lifespan of HTTPS Certificates

(August 15, 2019)

An industry group, the CA/Browser Forum, is considering a proposal that would limit the lifespan of HTTPS certificates to no more than 13 months. The certificates are currently valid for a maximum of 27 months from the date of issue. Shortening the length of time certificates are valid reduces the likelihood that outdated and unsecure encryption algorithms will persist in the Internet ecosystem. Critics of the proposal say that its benefits do not outweigh the hassle of renewing certificates more frequently. If the proposal receives enough votes, it will take effect in March 2020.


[Editor Comments]


[Pescatore] Over the years, SSL certificate lifespans have been shortened from 8 to 3 to 2 years and this same debate has occurred. I don't think there is any data that can show any decrease in actual damage because of shorter lifespans but they do enable shorter transition times when key length increases or other crypto changes are agreed upon. There is also a benefit in forcing organizations to go to yearly cycles of tracking and budgeting for certificates in the same way they do software licenses.


[Neely] If you have automated mechanisms of updating your HTTPS certificates, the lifespan is not a big impact. Most organizations I've interacted with are still manually requesting and installing their certificates and shortened intervals are not appealing. In this case, creating a recurring service ticket assigned to the right group is the best hope for keeping an eye on expiring certificates.
