For the fourth day in a row the DHS ICS-CERT updated their
alert for the WannaCry ransomware. It was originally
published on Monday and the latest
update was yesterday. Today’s update adds links to WannaCry notifications
from the following vendors:
• Siemens (Radiation
Oncology Products; Biograph
mMR; Point-of-Care
Products; and Advanced
Therapy Products);
• Tridium;
and
The update also provides a link to a general WannaCry support
document from Siemens Healthineers. This document and a further linked
Siemens’ blog
post provides a good technical discussion of the WannaCry problem and
solutions; including links to Microsoft updates for ‘unsupported’ (outdated?)
Windows operating systems still in use by Siemens Healthineer (and too many
other industrial control) products.
