IEC 62351 Standards for Securing Power System Communications

IEC 62351 Standards for Securing Power System Communications

To help counter the growing concern about cyberattacks aiming to disrupt power systems, industrial experts have been working together in WG15. This group, part of IEC, is defining the standards known as IEC 62351, for secure-by-design power grids.

As a member of WG 15 since 2015, I thought it might be helpful to inform you about these standards and provide an update on their status.

Analyzing the GreyEnergy Malware: from Maldoc to Backdoor

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

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

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

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

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.
