Common Attack Types: The most common types of attacks the company has faced is Vulnerability.

Identification of Attack Vectors: The company identifies the attack vectors used in incidents through Weak Password ('Louvre'/'Thales')Unguarded Rooftop Access.

Average Financial Loss: The average financial loss per incident is $33.33 million.

Prevention of Data Exfiltration: The company takes the following measures to prevent data exfiltration: Potential Password Policy Updates, Physical Security Reinforcements (Post-Incident), , Full security review, Governance policy updates, Camera upgrades, Cybersecurity protocol updates, .

Key Lessons Learned: The key lessons learned from past incidents are Even high-profile institutions can fall victim to basic cybersecurity oversights (e.g., weak passwords, outdated systems).,Physical and digital security are intertwined; vulnerabilities in one can exacerbate risks in the other.,Password hygiene (e.g., avoiding default/guessable passwords, using password managers) is critical for all organizations.,Regular audits and updates to security systems (software, physical access controls) are essential to mitigate risks.Critical infrastructure like cultural institutions must prioritize cybersecurity hygiene, including: (1) Enforcing strong password policies and MFA, (2) Phasing out unsupported legacy systems, (3) Regular penetration testing and audit transparency, (4) Segmenting networks to limit lateral movement.Outdated software in critical infrastructure (e.g., surveillance systems) can enable physical security breaches and expose organizational vulnerabilities. Proactive cybersecurity audits and timely system updates are essential for risk mitigation.
