Threat Intel Weekly #15 — 3 Threats to Watch (April 10–13, 2026)
This week (April 10–13, 2026) was particularly rich in cybersecurity news.
Here are the 3 threats that caught my attention — with concrete actions to take for each one.
🔍 The 3 Threats of the Week
Unauthenticated RCE — Marimo
Remote Code Execution (RCE)
- No authentication required to exploit the vulnerability
- Remote code execution possible
- Potential full system takeover
- Exploitation observed very quickly after disclosure
4,000 Industrial Devices Exposed (OT/IoT)
OT Exposure / Critical Infrastructure
- SCADA, PLC and critical infrastructure accessible from the internet
- Potentially state-sponsored activity identified
- Poorly segmented and insufficiently secured environments

🛡️ Priority Actions for the Week
If you could only remember three actions:
- 1Apply critical patches promptly (Marimo and any CISA KEV patch)
- 2Audit your exposure surface — especially IoT/OT devices accessible from the internet
- 3Strengthen vigilance against fraud: train your teams on social engineering patterns
🔮 Watch Next Week
- 📅Microsoft Patch Tuesday — monthly patches to apply
- 📌New vulnerabilities added to the CISA KEV catalogue
📈 Trends of the Week
Three key findings to remember:
✔ Critical vulnerabilities are exploited very quickly after disclosure
✔ OT environments remain highly exposed and targeted
✔ Attacks targeting users (fraud, phishing) continue to grow
