Siemens SIPROTEC Vulnerability: Unplugged and Unprotected!
CISA will no longer update ICS security advisories for Siemens product vulnerabilities beyond the initial advisory. For the freshest scoop on SIPROTEC 4 vulnerabilities, head over to Siemens’ ProductCERT Security Advisories. Remember, even cyber villains need their tools up-to-date—let’s not make it easy for them!

Hot Take:
In the world of cybersecurity, it’s not just the hackers who are causing headaches. Sometimes, it’s the devices themselves throwing a tantrum! Siemens’ SIPROTEC 4 line seems to have a penchant for playing “hard to get” with security updates, leaving everyone in a state of denial… of service. It’s like the products are having a mid-life crisis, and the only fix is a good old-fashioned restart. Remember when turning it off and on again was just IT folklore? Now it’s a critical survival skill!
Key Points:
- CISA will stop updating ICS security advisories for Siemens beyond the initial advisory.
- The vulnerability affects various Siemens SIPROTEC 4 and SIPROTEC 4 Compact products.
- The issue allows for a denial-of-service condition via interrupted file transfers.
- Mitigations include updates for some products, but others are left hanging with no fixes planned.
