France had more Internet-exposed Danfoss refrigeration dashboards than the rest of the world combined before the supermarket attacks (weekly IPv4 scan data)

I work at IPinfo, which runs a weekly scan of the IPv4 Internet. Short version of what we found: October 6–7 scan, five days before the attack: 2,528 addresses serving a Danfoss StoreView dashboard in 73 countries and territories. France had 1,331 (53%). 85% of the French ones ran software with known flaws, including 527 end-of-life AK-SM 800 units. Only 195 had every fix. Elsewhere it was 84%, so France had more of them online, not worse patching. 1,019 of the French addresses were already open on March 30. October 14 scan: 316 still online in France (−76%, against a normal 3–7% weekly loss). Fully patched units dropped too (195 → 54), which points to disconnection rather than patching. Method: the newer UI is matched on page title, the older AK-SM 800 on its web server plus the Flash loader page, and firmware generation comes from the build date the dashboard exposes. Counts are addresses on the ports we scan, so they’re a floor. How the attackers got in is still unknown, and exposure isn’t proof of the entry point. submitted by /u/seremot [link] [comments]Technical Information Security Content & DiscussionRead More
