The patch released on 14 April relates to all versions of windows and CyberKeel application that is most affected is used to host webpages.
The cyber-security company spot-checked 50 maritime websites and found that 37% of those using Microsoft web servers had not been patched.
According to CyberKeel these sites in included included three major container line and systems at a number of ports, such as the vessel traffic management system in Gothenburg, the road haulier identity system in Felixstowe and the main site of the Copenhagen port authority.
“Complex systems, such as those provided by Microsoft, are often in need of software patching to plug security holes. Companies need their IT departments to be able to quickly install software patches, as the hacker community operates on decidedly short timeframes,” said Lars Jensen, ceo of CyberKeel.
“As an example, it took less than 12 hours from the point where Microsoft released the patch, until you could find simple instructions on the internet as to exactly how to exploit this weakness to cause a denial of service.”
