OT:ICEFALL Research from Forescout Explores Insecure-by-Design State of Operational Technology

OT:ICEFALL Research from Forescout Explores Insecure-by-Design State of Operational Technology

The latest research from Forescout’s Vedere Labs explores the state of risk management in operational technology through the lens of 56 insecure-by-design vulnerabilities.

背景說明

On June 20, Forescout’s Vedere Labs published their latest research findings into operational technology (OT) vulnerabilities titled OT:ICEFALL. This group has been examining vulnerabilities affecting OT security for a few years now and has produced notable findings including: NUCLEUS:13, NAME:WRECK, NUMBER:JACK and AMNESIA:33.

OT:ICEFALL sought to analyze and understand the prevalence and impact of insecure-by-design vulnerabilities in OT products. The researchers took a systemic look at OT risk management. The research notes that many factors complicate OT risk management including the certification of vulnerable products, lack of CVE assignment and supply chains propagating vulnerabilities. In the course of this research, Forescout also disclosed 56 vulnerabilities across nine vendor’s products. A tenth vendor is also affected by four vulnerabilities, but they are still going through the disclosure process.

分析

The 56 vulnerabilities are all tied to “insecure-by-design” flaws common in the OT space within the following products:

Vendor Impacted Products
Bently Nevada

3700

TDI equipment

Emerson

DeltaV

Ovation

OpenBSI

ControlWave

BB 33xx

ROC

Fanuc

PACsystems

Honeywell

Trend IQ

Safety Manager FSC

Experion LX

ControlEdge

Saia Burgess PCD

JTEKT Toyopuc
Motorola

MOSCAD

ACE IP gateway

MDLC

ACE1000

MOSCAD Toolbox STS

Omron

SYSMAC Cx series

Nx series

Phoenix Contact ProConOS
西門子 WinCC OA
Yokogawa STARDOM

These vulnerabilities can be grouped into four categories:

  • Insecure engineering protocols
  • Weak cryptography or broken authentication schemes
  • Insecure firmware updates
  • Remote code execution via native functionality

In a worst case scenario, an attacker with network access to a vulnerable device could exploit some of these flaws to “remotely execute code, change the logic, files or firmware of OT devices, bypass authentication, compromise credentials, cause denials of service or have a variety of operational impacts.” According to Forescout, 35% of the 56 vulnerabilities disclosed could allow for firmware manipulation or remote code execution.

This research harkens back to past industrial attacks, like Industroyer and TRITON, that relied on similar insecure-by-design flaws in their targeted OT environments. It also traces its history to Project Basecamp, an effort by Digital Bonds in 2017 to “highlight and demonstrate the fragility and insecurity of most [supervisory control and data acquisition] SCADA and [distributed control system] DCS field devices.”

概念驗證

There are no proofs-of-concept available for any of the 56 vulnerabilities disclosed. Because “many of [these vulnerabilities] will remain unpatched in production environments for a significant amount of time,” Forescout did not release any technical details of the individual vulnerabilities discovered through the course of its research.

Vendor response

Forescout does not provide specific details on whether or when any of the vendors will be patching these vulnerabilities. Organizations should monitor for vendor advisories from all of their OT providers.

The Cybersecurity and Information Security Agency has also published an advisory for OT:ICEFALL, along with five Industrial Controls Systems Advisories for some of the affected products. Yokogawa has also issued an advisory for the vulnerabilities in its STARDOM product.

解決方法

The best defense for these vulnerabilities at this time is to ensure OT best practices are being followed.

  • Assess systems for vulnerable devices
  • Segment vulnerable devices, particularly from the internet
  • Use secure methods for remote access when that access is necessary to operations
  • Keep up to date on patches from vendors and establish remediation practices
  • Develop network monitoring rules to block or alert for anomalous traffic
