Protecting Entertainment and Media: Analyzing Cyber Threats and Prevention Strategies in the Wake of Funke Media Group, Netflix, and HBO Incidents

CVE Image for report on Cybersecurity in Entertainment and Media

Executive Summary

The entertainment and media industry, a sector characterized by its high-profile content and extensive digital infrastructure, has become an attractive target for cybercriminals. Recent cyber incidents, such as the ransomware attack on Funke Media Group and data leaks involving Netflix and HBO, underscore the vulnerabilities within this industry. This report provides a detailed analysis of these incidents, the threat actors involved, and the tactics, techniques, and procedures (TTPs) they employed. Additionally, it offers actionable mitigation strategies to help organizations bolster their cybersecurity posture.

Technical Information

The entertainment and media industry is increasingly reliant on digital systems for content creation, distribution, and consumption. This digital transformation, while offering numerous benefits, also exposes the industry to a myriad of cyber threats. The Funke Media Group ransomware attack in December 2020 serves as a stark reminder of the potential operational disruptions that can result from such incidents. The attack, which affected over 6,000 enterprise computers, was executed using file-encrypting malware, a common tactic among ransomware groups. This incident highlights the importance of implementing robust backup solutions, conducting regular security audits, and ensuring that all systems are patched and up-to-date.

In 2017, the entertainment industry witnessed another significant cyber incident when hackers leaked unreleased episodes of Netflix's "Orange Is the New Black" and HBO's "Game of Thrones." The attackers, known as "little.finger66," claimed to have stolen 1.5 terabytes of data from HBO. This attack involved unauthorized access to internal systems and exfiltration of sensitive data, emphasizing the need for media companies to enhance their cybersecurity posture. Implementing multi-factor authentication, monitoring network traffic for anomalies, and conducting regular employee training on phishing and social engineering attacks are critical measures to prevent such breaches.

The decentralized nature of media production, involving numerous third-party contractors, introduces additional security challenges. A breach at a contractor can compromise the entire supply chain, as demonstrated by the Netflix data leak incident. To mitigate these risks, organizations should adopt a centralized security strategy that includes all partners and suppliers. This involves conducting thorough security assessments of third-party vendors and integrating them into the organization's cybersecurity framework.

Leveraging cyber threat intelligence is another effective strategy for mitigating cyber risks. Centripetal's CleanINTERNET offers a next-generation threat intelligence solution that helps entertainment organizations shield against 99% of globally identified cyber threats. By aggregating and managing over 3,000 cyber threat feeds, CleanINTERNET provides real-time threat detection and prevention, reducing security alerts by up to 70% and ensuring compliance with industry regulations such as GDPR and CCPA.

Exploitation in the Wild

The Funke Media Group ransomware attack and the Netflix and HBO data leaks are prime examples of how cybercriminals exploit vulnerabilities within the entertainment and media industry. The ransomware attack on Funke Media Group involved the use of file-encrypting malware to extort the organization by holding their data hostage. In the case of Netflix and HBO, the attackers gained unauthorized access to internal systems and exfiltrated sensitive data, which they later leaked to the public.

APT Groups using this vulnerability

While specific Advanced Persistent Threat (APT) groups have not been explicitly linked to the incidents mentioned, the tactics employed are consistent with those used by well-known ransomware groups and cybercriminals targeting the media industry. These groups often exploit vulnerabilities in digital systems and leverage social engineering techniques to gain unauthorized access to sensitive data.

Affected Product Versions

The Funke Media Group ransomware attack affected over 6,000 enterprise computers, though specific product versions were not disclosed. In the case of the Netflix and HBO data leaks, the attackers targeted internal systems, but again, specific product versions were not detailed in the reports.

Workaround and Mitigation

To mitigate the risk of ransomware attacks, organizations should implement robust backup solutions, conduct regular security audits, and ensure that all systems are patched and up-to-date. For data breaches involving unauthorized access, media companies should enhance their cybersecurity posture by implementing multi-factor authentication, monitoring network traffic for anomalies, and conducting regular employee training on phishing and social engineering attacks. Additionally, adopting a centralized security strategy that includes all partners and suppliers is crucial for mitigating third-party risks.
