Defending Critical Infrastructure Against Cyber Risk


Nozomi Networks Labs is dedicated to reducing cyber risk for the world’s industrial and critical infrastructure organizations.

Through our cyber security research, and collaboration with industry and institutions, we’re helping defend the industrial systems that support everyday life.

Collaborating to Reduce ICS Cyber Risk

Nozomi Networks Labs is working with a broad range of experts, industry leaders and institutions to improve industrial cyber security.

If you’d like to work together, we’d love to hear from you!

Analyzing the GreyEnergy Malware: from Maldoc to Backdoor

GreyEnergy is an Advanced Persistent Threat (APT) which has been targeting industrial networks in Eastern European countries for several years.

As a security analyst, I have studied the malware and provide a detailed description of how it works, from the moment that someone receives a phishing email, until the malware is installed in a PC. We also provide the GreyEnergy Unpacker, a free tool for other analysts to use for further analysis of this advanced persistent threat.

GreyEnergy Malware Targets Industrial Critical Infrastructure

Recently a new advanced threat targeting the energy sector was disclosed. Called GreyEnergy, this malware is the successor to BlackEnergy, which brought down part of the Ukraine power grid in 2015.
Because of the significance of the malware, our Nozomi Networks Security Research team is evaluating it. Find out what is known about the malware to date.

Open Source Software Exposes ICS Device Vulnerabilities to Hackers

It’s disturbing to think that disruption and damage to our critical infrastructure can happen by simply combining the use of OSS tools with malicious intent. Fortunately, those same tools are being used by ICS security researchers around the world to increase industrial control systems cyber security.

Read on to learn why transportation, communications, energy and emergency services are so exposed, and what’s being done to close the ICS cyber security gap.

Black Hat: Understanding TRITON, The First SIS Cyber Attack

Today at Black Hat USA I am part of a team speaking about the landmark TRITON malware attack. We are presenting new research on TRITON, releasing two tools to help defend against it and publishing a white paper summarizing our findings.

The TRITON malware attack went beyond other industrial cyber attacks by directly interacting with a Safety Instrumented System (SIS). Asset owners should act immediately to secure their SIS — and the information in our white paper will help.

New TRITON Analysis Tool: Wireshark Dissector for TriStation Protocol

In 2017, TRITON malware was used to attack a gas facility, directly interacting with its Safety Instrumented System (SIS). Given the significance of this attack, Nozomi Networks conducted research to better understand how TRITON works.

Today we released a Wireshark dissector for the TriStation protocol on GitHub to help the ICS community understand SIS communications. Our complete TRITON analysis will be presented at Black Hat USA 2018.

New TRITON ICS Malware is Bold and Important

FireEye has reported that it has recently worked with an industrial operator whose facility was attacked by a new type of ICS malware, which they are calling TRITON. The attack reprogrammed a facility’s Safety Instrumented System (SIS) controllers, causing them to enter a failed state, and resulting in an automatic shutdown of the industrial process.

The TRITON attack is bold and notable because it is the first known industrial control system (ICS) attack that has targeted and impacted not just an ICS, but SIS equipment. Fortunately, because of the unique nature of how each plant implements its SIS and overall safety measures, the malware is not readily scalable.

Bad Rabbit Highlights Employees’ Role in Cyber Security Attacks

Recently reports of a new ransomware malware known as Bad Rabbit was making headlines in the press. A suspected variant of NotPetya, Bad Rabbit spread quickly through IT networks in Europe and elsewhere.
Our research indicates that while Bad Rabbit infections started to be reported in late October, the group behind the attacks started creating an “infection-network” in July. While not reported as impacting industrial systems, industrial operators should take note of this attack and what it means for their cyber resiliency programs.

Advancing IEC Standards for Power Grid Cyber Security

Last week Nozomi Networks had the privilege of hosting the first WG15 meeting of 2017. This group is responsible for establishing end-to-end cyber security standards for the world’s power system communication protocols. Read on to learn more about WG15 and how we advanced standards for encrypted communications for the power grids of the future.

Curated and maintained by Nozomi Networks Labs, the OT ThreatFeed™ provides threat and vulnerability updates to Guardian, making it easy for IT/OT professionals to stay on top of current ICS risks.

“Threat actors love finding new ways to attack critical infrastructure. We love finding new ways to detect their malware before damage occurs.”
