Danfoss-managed refrigeration systems in French supermarkets were hacked, causing temperatures to rise to 50°C. The attack exploited default credentials and outdated firmware in the systems.

Commenters largely agree the breach stemmed from poor security practices, with Treczoks calling it a 'complete failure' for using easily guessable credentials and outdated systems. Others, like notannpc, argue against connecting critical appliances to the internet, while whyNotSquirrel criticized the use of the current date as a password. Thallamabond highlighted the 'code of the day' flaw in Danfoss systems as a known vulnerability.

The consensus is that the attack was due to basic security lapses, not sophisticated hacking. However, there is a divide between those who see it as a setup failure and those who believe it reflects poor software engineering standards. The key takeaway is that industrial devices remain vulnerable due to outdated systems and weak security practices.
