Security incident targeting Danfoss AK-SM and AK-SC series (October 12, 2026)

The CERT-FR is aware of multiple compromises of Danfoss AK-SM and AK-SC series devices. The exposure of management interfaces on the internet contradicts security best practices. Where remote administration is necessary, restricting access represents an interim mitigation measure.

Why it matters: Organizations operating Danfoss AK-SM and AK-SC controllers need to audit internet-exposed management interfaces and implement access controls immediately to prevent further compromise.
