Webinars & Podcasts
Investigating the Ransomware and IoT Vulnerabilities Landscape
Panelists: Ivan Speziale, Chris Grove
Date: July 27, 2021
Cybercrime continues to rise sharply as threat actors go after industrial targets that can be worth millions in ransomware payments. To help security defenders fight back, Nozomi Networks Labs will share insight from its new research into the current security landscape.
Insights on the Top OT/IoT Security Threats – How to Protect Your Operations
Panelists: Alessandro Di Pinto, Ivan Speziale, Chris Grove
Duration: 50+ minutes
To help you address accelerating OT/IoT security issues, the Nozomi Networks Labs team shares their new research findings on the top threats targeting critical infrastructure and industrial operations. Learn about the current OT/IoT threat landscape, supply chain threats to OT and IoT environments, ransomware risks, and how to protect your critical OT/IoT networks.
P2P Botnets: Following the Network Trail Podcast & Webinar
Panelists: Ivan Speziale, Giannis Tsaraias, Chris Grove
Duration: 30+ minutes
To increase botnet resiliency, threat actors are now using a hybrid model, rather than a pure peer-to-peer one. While disrupting the malicious activity of P2P botnets can be challenges, there are proven strategies that can be follow when a specific network is affected. Learn about how P2P/hybrid botnets operate, how to spot botnet infections in your network, and the most effective ways to disrupt them.

Guardian Community Edition Assertions (Queries) for COVID-19 Cybersecurity
New assertions (queries) have been added to Guardian Community Edition to help with COVID-19-related cybersecurity challenges.
- Assertions for COVID-19 Network Indicators – Queries that check for communications with malicious IP addresses and URLs
- Assertions for Remote Access Monitoring – Queries that check the number of simultaneous remote connections and generate alerts if the number surpasses a threshold.

URGENT/11 Nmap NSE Script for Detecting Vulnerabilities
- Our Nmap NSE script for detecting URGENT/11 vulnerabilities is a research tool for quickly checking industrial systems for vulnerable assets based on the version of VxWorks exposed within the FTP service.
- Due the fact that is not always possible to detect the running version, we recommend that industrial operators use full featured security products for effective vulnerability assessment.

Research Projects
IEC 62351 Standards for Securing Power System Communications
IEC Working Group 15 (WG15) is developing technology standards for secure-by-design power systems. Labs contributes to the standards and has demonstrated how they can be used to identify hard-to-detect cyberattacks. Research from this effort was presented at Black Hat USA 2019.
GreyEnergy: Dissecting the Malware from Maldoc to Backdoor
The Labs team reverse engineered the GreyEnergy malicious document (maldoc) that leads to the installation of the malware (backdoor) on a victim’s network. Project outcomes include a report, multiple blogs and two free tools for security researchers.
TRITON: The First ICS Cyberattack on Safety Instrument Systems
TRITON is the first known cyberattack that directly interacted with a Safety Instrumented System (SIS). Labs reverse engineered the TriStation suite of software and delivered a report and two free tools for security researchers. This research was presented at Black Hat USA 2018.
Threat Intelligence
Curated and maintained by Nozomi Networks Labs, the Threat Intelligence™ service provides threat and vulnerability updates to Guardian, making it easy for IT/OT professionals to stay on top of current OT and IoT risks.
“Threat actors love finding new ways to attack critical infrastructure. We love finding new ways to detect their malware before damage occurs.”
