Key Points:
- Microsoft has seen a significant increase in attacks targeting poorly secured OT (Operational Technology) devices connected to the internet.
- Water and wastewater systems (WWS) in the US have been specifically targeted by nation-backed actors, including Iranian and pro-Russian groups.
- These attacks highlight the critical need to improve OT security practices to prevent disruptions to essential services.
Why it Matters:
- OT systems control critical infrastructure like water treatment plants, power grids, and building automation.
- Successful cyberattacks on OT systems can cause malfunctions, outages, or even physical harm.
- OT devices are often inadequately secured, with weak passwords, outdated software, and direct internet connections.
Recommendations:
- Strengthen OT security by segmenting networks, implementing strong authentication, and keeping software up-to-date.
- Limit internet exposure of OT devices whenever possible.
- Stay informed about the latest cyber threats and vulnerabilities.
