The cybersecurity error at the Louvre that allowed the historic theft

When we talk about digital protection, we usually think of firewalls, encryption or intrusion detection. But the theft of jewelry at the Louvre Museum has brought to the table a simpler — and more dangerous — reality: a banal password can reveal even one of the most secure cultural institutions in the world.

‍

What has happened?

According to French media, the attackers managed to infiltrate the museum's video surveillance system using access credentials that were literally “LOUVRE”. With this digital key, they were able to deactivate alarms, manipulate cameras and act freely within the enclosure. In a matter of minutes, several priceless historic jewels were stolen before disappearing without a trace.

A bug that goes beyond a password

What happened at the Louvre was not just a poor choice of password, but a symptom of a structural problem: the lack of cybersecurity policies adapted to non-technological environments.
Museums, such as hospitals or critical infrastructure, tend to prioritize physical security, but they neglect the digital protection that controls those same systems. The absence of audits, shared passwords, and a false sense of security facilitated unauthorized access.

In addition, this case highlights another growing challenge: the convergence between operational technology (OT) and information technology (IT). When camera, climate or access control systems are connected to the network, any digital divide can have immediate physical consequences.

Key Lesson

The Louvre robbery isn't just a media anecdote: it's a global warning.
Attackers no longer need to force locks when digital doors are opened by negligence. In cybersecurity, the simplest errors — a weak password, a default configuration — are those that open the door to the greatest losses.

What we recommend from Apolo Cybersecurity

At Apolo Cybersecurity, we insist that these types of incidents are totally preventable with proactive digital security management. We recommend:

• Audit credentials and critical access, especially in connected systems (video surveillance, access control, air conditioning, etc.).
• Implement multifactor authentication (MFA) to prevent unauthorized access even if a password is leaked.
• Train staff to detect and avoid bad practices such as simple or shared passwords.
• Separate networks and segment systems, preventing access to a camera from compromising the entire infrastructure.
• Review the security policies of external providers and services that manage connected systems.
