---Industrial Controls Systems Manufacturer Systems Hit with Ransomware

(October 21, 2019)

German Automation tool manufacturer Pilz was hit with ransomware more than a week ago. According to the company's website, "all servers and PC workstations, including the company's communication, have been affected worldwide." Updates to the website note that email was restored in subsidiaries on October 18, and that the company was able to restore deliveries for certain areas as of October 21.


[Editor Comments]


[Paller] Consider the very real situation where your ICS vendor manages your power or other systems remotely. This is a wake-up call for ICS vendors to massively upgrade their own cyber hygiene.

--Ransomware Targeting Italian Office 365 Users - Set to Music

(October 18, 2019)

Office 365 users in Italy are being targeted by ransomware attacks. The malware makes its way onto machines through email messages that pretend to be invoices, resumes, or other business documents; the messages contain a .vbs file that encrypts files and downloads a malware loader. This particular attack has a quirk: the .vbs file also downloads and plays music while the victim's files are being encrypted.


[Editor Comments]


[Murray] E-mail and "browsing" should be isolated from mission critical applications.

--Second Draft of DoD Cybersecurity Maturity Model Certification Coming in November

(October 18 & 21, 2019)

The first public draft of the US Department of Defense's (DoD's) Cybersecurity Maturity Model Certification, which establishes cybersecurity standards for government contractors, has received more than 2,000 comments since it was released on August 30, 2019. The second draft is expected to be released for comment in early November. The official version is expected to be released in January 2020.

--Air Force Upgrades SACCS from Floppy Disks

(October 17 & 18, 2019)

The US Air Force has finally phased out the use of 8-inch floppy disks used in its Strategic Automated Command and Control System (SACCS), which is used to relay messages regarding US nuclear capability. Instead, the facility moved to a "highly-secure solid state digital storage solution" earlier this year.


[Editor Comments]


[Neely] I haven't used an 8" floppy in at least 25 years. Note that they have only replaced the floppy disks with newer storage; the 1976 era IBM Series/1 systems are still in place. While this system is a model of control systems designed for a long life, keeping a system this old operational requires technicians skilled in repairing and understanding technology that has no spare parts. Including the ability to service long-lived systems has to be part of the lifecycle management and your risk register.


[Murray] This may be the poster child for legacy systems.

--Girl Scouts of America Pilots Cybersecurity Challenge

(October 18, 2019)

The Girl Scouts of America's (GSA's) Girl Scouts Cyber Challenge took place on Saturday, October 19. More than 3,000 scouts signed up to participate. The challenge was piloted at councils in 10 states. It it is deemed successful the next challenge will be expanded to include all 111 councils.  


[Editor Comments]


[Pescatore] Nice to see the progress in the two years since we all commented on this being a very valuable initiative.


[Neely/Murray] This is exciting; applause to GSA and Raytheon for providing this opportunity. Building these skills aligns with our shortage of cybersecurity workers. Efforts like these will not only spark interest but also help raise the skills of students entering into training and education programs.


[Murray] We now have degree programs at all levels as well as established hands-on training programs. We should encourage and support programs like this Girl Scout program to fill the pipeline into higher education and industry training.

--Cybersecurity and Healthcare

(October 17, 2019)

The Do No Harm 2.0 report from New America, a Washington, DC-based think tank, "aim[s] to highlight the need to mitigate the risks to patient safety created by the growing integration of information technology and operational technology into healthcare, and to propose ways to mitigate that risk." The report makes 17 policy recommendations, including holding the board of directors responsible for healthcare privacy and security and strengthening FDA requirements for medical device security to ensure security is baked in.

--FAA Drone ID Requirements

(October 20, 2019)

The FAA is scheduled to issue a rulemaking statement requiring drones to emit a signal indicating aircraft and ownership information. This is a critical step for integration of unmanned aircraft into the National Airspace System. Remote identification is considered essential for beyond visual line of sight operations, which many drones support.


[Editor Comments]


[Neely] While law enforcement want information to provide ownership information when dealing with reckless or unlawful operators, the topics that need to be worked out include what information should be transmitted; how it should be collected and safeguarded and weather unlawful operators would bother to transmit accurate information, if any.


[Pescatore]  Warning, will skew old here - you might want to skip to the next comment or item. Back in 1982 while working at the US Secret Service I did an investigation into how to protect against attacks by radio-controlled airplanes. That was pre-GPS, 5G, remote video - the ability for drones to be used maliciously beyond line of sight is exponentially higher today. Having Identify Friend or Foe technology built-in is going to be a necessary requirement but dealing with drones that are declared "foes" is a very complex topic.

--Microsoft Secured-Core PC Aims to Protect Computers from Firmware Attacks

(October 21, 2019)

Working in partnership with its manufacturers, Microsoft is developing a feature to protect PCs from firmware attacks. Secured-Core PC changes the way the machines boot up so it can detect anomalies before they take root in PCs. It takes away firmware's role in determining software integrity on boot up and shifts the integrity checks to new CPUs.


[Editor Comments]


[Murray] Apple has demonstrated how to do this, at least in closed systems. It is an important tactic in securing the "supply chain."

--NordVPN Confirms 2018 Breach

(October 21, 2019)

NordVPN has acknowledged that one of its data centers was breached in March 2018. The attacker accessed a server at a data center in Finland through an unsecured remote management system. In a blog post about the incident, NordVPN writes, "The attacker gained access to the server by exploiting an insecure remote management system left by the datacenter provider while we were unaware that such a system existed."


[Editor Comments]


[Neely] Although the breach occurred in March 2018 and all involved servers have been "shredded", the breach included an expired TLS private key. Nord delayed notification to allow time to take and verify steps to prevent recurrence. In today's marketplace more rapid communication and transparency is needed to support claims of security, particularly for a service such as a VPN. If you are a NordVPN user, you may want to refresh your chosen VPN server to make sure current secure servers are used.


[Murray] This is called a "back door." These are sometimes the result of error but are often sponsored by nation state actors or criminal enterprises.

--Autoclerk Database Exposed Online

(October 21, 2019)

A Elasticsearch database belonging to the Autoclerk reservations management system was left unprotected on the Internet. The database contains data related to more than 100,000 bookings. The compromised information includes unencrypted login credentials and travel arrangements. Among the affected booking entities are government contractors responsible for arranging travel for government and military personnel.


[Editor Comments]


[Murray] The Verizon Data Breach Incident Report suggests that "orphan data" is a cause of data leakage.
