 --TRISIS/TRITON Malware Triggered Operational Shutdown at Unnamed Facility

(December 15 & 18, 2017)

Industrial Control System malware known as TRISIS or TRITON malware was found on the network of an unnamed company in the Middle East. TRISIS/TRITON targets Schneider Electrics Triconex Safety Integrated Systems (SIS) controllers. Researchers believe that the malware was used with the intent of causing physical damage to the facility, but instead triggered an operational shutdown, which prompted an investigation.


[Editor Comments]

[Assante] The malware is significant in its focus and capabilities along with providing a lens back into its creators. The incident, as described, indicates the attackers had high degree of confidence in their developed access deep into the Operational Segments of the targeted facility. We have been teaching about the risk that comes with connections between engineering workstations and SIS controllers. The investment made by these attackers in developing a malware that can interface and manipulate a specific SIS technology along with their experimentation inside of a production system makes it very likely that we will see this used again.

 --DHS Pilot Program Finds Flaws In First Responder Apps

(December 18, 2017)

A project piloted by the US Department of Homeland Security's (DHS's) Science and Technology Directorate has found 18 critical vulnerabilities in mobile apps used by first responders and other public safety officials. All but one of the 33 iOS and Android apps the program tested were found to pose security and/or privacy concerns.  


[Editor Comments]

[Neely] This is an excellent move for First Responder Apps. A similar approach can be applied to other sector specific critical applications. There are too many mobile applications changing rapidly for a ubiquitous solution to be viable. You may wish to consider creating an analysis capability for mission critical mobile applications.

 --Delaware Governor and CSO Receive SANS Difference Maker Award

(December 15, 2017)

Delaware Governor John Carney and Chief Security Officer Elayne Starkey have received a 2017 SANS Difference Maker Award acknowledging Delaware "as a leader across the nation in cyber security awareness, education, and training." More than 350 high school and college students in Delaware participated in the CyberStart Program; of those, 20 students earned scholarships for further advanced cyber security study. Governor Carney has signed into law a bill that requires all public and charter high schools in the state to offer at least one computer security course. Carney also launched the NSA Day of Cyber School Challenge, a free program aimed at sparking interest in cybersecurity among students.  


[Editor Comments]

[Neely] Providing cyber awareness education and training in high school needs to be SOP. Kudos to Carney and Starkey for raising the bar. Hope others will follow suit.

 --American Hospital Association Asks FDA to Actively Address Medical Device Security

(December 12, 2017)

The American Hospital Association (AHA) wants the US Food and Drug Administration (FDA) to step up effort to ensure that medical device manufacturers bear responsibility for the digital security of their products. Responding to an FDA request for information about how the agency can help reduce regulatory burdens, AHA VP Ashley Thompson noted that even though the FDA has released cybersecurity standard guidance for medical devices, "device manufacturers have yet to resolve concerns, particularly for the large number of legacy devices still in use."  


[Editor Comments]

[Pescatore] While I'm a big believer in cybersecurity legislation only as a last resort, the medical machinery/device industry has had over a decade to focus on security and has failed. As far back as January 2005, the FDA issued guidance on cybersecurity for medical equipment that has largely been ignored. The FDA needs to act more like the FTC and take action when companies fail at protecting their customers.


[Neely] Modern medical devices managed, monitored and controlled using what is now commodity hardware and a security framework is needed insure the security of those systems is sufficiently robust. Additionally, standards need to include consequences for non-compliance to move adoption forward.


[Northcutt] Dr. Gottlieb, FDA, is correct that the procedural framework needs a major overhaul:

https://blogs.fda.gov/fdavoice/index.php/2017/12/advancing-policies-to-promote-safe-effective-medtech-innovation/

If you work in IT/cybersecurity in the healthcare field, you can review and comment of the documents which are supposed to air in the first quarter of 2018:

https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/ucm580172.htm

Executive Order 13777 and 13771 direct the review of cumbersome regulations, but don't include any language to hold medical device manufacturers accountable. Litigation after death or injury may be the only recourse:

Bossert maintains that the allegation is based on evidence and plans to make (an official) statement on Tuesday, December 19. (Please note that the WSJ story is behind a paywall.)

 --Fox-IT Was Victim of Man-in-the-Middle Attack

(December 14 & 18, 2017)

Security company Fox-IT has acknowledged that it was the target of a Man-in-the-Middle (MitM) attack in September. The attacker accessed the Fox-IT.com domain DNS records at a third-party domain registrar and modified a DNS record for a certain server to point to a server in the attacker's possession/control so they could intercept traffic. The total time of the attack was roughly 10.5 hours. The Fox-IT blog includes a detailed time line of the attack.


[Editor Comments]

[Neely] This is a case of inadequate security for an outsourced function, in this case DNS. Also, a reminder to review the security capabilities of your service providers to make sure that they are keeping up with current best practices and to verify they meet your current security needs e.g. Multi-Factor authentication.  Fox-IT had both full packet capture and analysis capabilities that enabled them to determine exactly what had been exfiltrated and take appropriate corrective actions. The Fox-IT blog is a quick read and gives an excellent synopsis of what happened and lessons learned that could start the conversation in your business.

Williams - I'm reluctant to call this a man in the middle (MitM) attack. This attack was simply a configuration change in a hacked DNS control panel that redirected users to a malicious site. MitM typically implies intercepting and modifying traffic at a midpoint - this is not that. That said, this should serve as a wake-up call to organizations to enable multi-family authentication on their registrar accounts if that service is offered. An attacker who takes control of the account has near complete control of their domain through DNS.

 --Emotet Trojan

(December 18, 2017)

The Emotet banking Trojan, detected by Bromium, is being described as polymorphic malware, meaning that "malware authors are repacking their malicious software into a unique executable for each potential victim" to avoid detection by malware analysis tools. Emotet was found to have evaded detection by 50 of 66 products with which it was tested.

 --Keeper Fixes Critical Flaw in Password Manager Plugin

(December 15 & 18, 2017)

A third-party password manager with a critical flaw was bundled with certain versions of Windows 10, according to Google researcher Tavis Ormandy. The flaw in the Keeper password manager is nearly the same as the one in the same plugin that Ormandy disclosed 16 months ago. Keeper Security has issued an update to address the vulnerability in the browser extension within 24 hours of being notified about the issue.
