A new malware called FrostyGoop has been linked to an attack in January 2024 that disrupted heating services in 600 apartments in Lviv, Ukraine. This malware allows attackers to interact with industrial control systems using the Modbus protocol. The attack involved sending unauthorized commands to heating system controllers, resulting in inaccurate measurements and loss of heating. Dragos recommends five baseline practices for ICS network protection.
Based on the meeting notes, the key takeaways are:
1. A new malware named FrostyGoop, discovered by researchers at Dragos, is designed to target industrial control systems (ICS) using the Modbus communication protocol, and it allows adversaries to interact directly with operational technology systems.
2. FrostyGoop poses a significant risk to the integrity and functionality of ICS devices and has the potential for disrupting and compromising essential services and systems in various industrial sectors.
3. The attack targeting a district energy company in Lviv, Ukraine, disrupted the heating services for nearly 48 hours by manipulating the heating system controllers using FrostyGoop, resulting in the distribution of cold water to the apartments.
4. The attack began with the adversaries gaining access to the energy company’s network in 2023 and later using FrostyGoop to target the heating system controllers, highlighting the potential for other cyberattacks on ICS environments with similar vulnerabilities.
5. Dragos recommends five baseline practices to protect ICS networks from such malware, including network segmentation, continuous monitoring, secure remote access, risk-based vulnerability management, and strong incident response capabilities.
These takeaways provide a clear understanding of the severity of the FrostyGoop malware and the critical steps recommended to safeguard ICS environments from similar attacks.
