Thieves steal $100M in jewels from Louvre after museum used own name as surveillance password

When thieves stole $100 million in jewels from the world-famous Louvre Museum in Paris, France, they shocked the art world and revealed a serious digital weakness. French media reports say the museum once used its own name, Louvre, as a password for its surveillance system.

That detail may sound unbelievable, yet it highlights how often people still rely on weak passwords even in high-security places that should know better.

Louvre password security flaws revealed in investigator’s audit

A decade-old French cybersecurity audit reportedly showed troubling gaps in the museum’s defenses. The Louvre is said to have once run outdated Windows Server 2003 software and had unguarded rooftop access, something eerily similar to how the recent thieves used an electric ladder to reach a balcony.

The biggest mistake? Using “Louvre” and “Thales” as passwords. One of them was even said to be visible on the login screen. That was like leaving the keys under the doormat of the world’s most famous museum.

CyberGuy reached out to the Louvre for comment, but did not receive a response before our deadline.

And while the Louvre may have tightened security since then, experts warn that password habits like these are still widespread among businesses and individuals.

Why Louvre’s weak passwords matter for your online security

You might not have priceless jewels to protect, but your personal data, financial info and digital identity are just as valuable to hackers. With the holiday shopping season here, cybercriminals ramp up their attacks, knowing millions of you are logging in, buying online and often reusing old passwords.

Protecting yourself online doesn’t have to be complicated. Follow these tips to boost your defenses:

• Avoid using your name or anything easily guessed.
• Mix uppercase and lowercase letters, numbers and symbols.
• Change passwords if a company you use reports a data breach.
• Skip sticky notes or digital files with unencrypted passwords.

Think beyond your phone or laptop. Your Wi-Fi router, smart home devices and even security cameras all have passwords that need attention.

Stay safe with a password manager

If keeping up with dozens of unique passwords sounds overwhelming, a password manager can help. These tools generate strong, unique, complex passwords for every account and store them securely in one encrypted vault. This reduces the risk of password reuse. Many password managers also alert you to compromised passwords or sites hit by data leaks.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager (see Cyberguy.com) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.
