26 October 2017: Inmarsat is aware of the IOActive report but it is important to note AmosConnect 8 (AC8) is no longer in service.
Inmarsat had begun a process to retire AmosConnect 8 from our portfolio prior to IOActive’s report and, in 2016, we communicated to our customers that the service would be terminated in July 2017.
When IOActive brought the potential vulnerability to our attention, early in 2017, and despite the product reaching end of life, Inmarsat issued a security patch that was applied to AC8 to greatly reduce the risk potentially posed. We also removed the ability for users to download and activate AC8 from our public website.
Inmarsat’s central server no longer accepts connections from AmosConnect 8 email clients, so customers cannot use this software even if they wished too.
It is important to note that this vulnerability would have been very difficult to exploit as it would require direct access to the shipboard PC that ran the AC8 email client. This could only be done by direct physical access to the PC, which would require an intruder to gain access to the ship and then to the computer. While remote access was deemed to be a remote possibility as this would have been blocked by Inmarsat’s shoreside firewalls.
Inmarsat made IOActive aware of these facts.
