Disney’s internal communications system has been compromised, leading to a significant data leak that has exposed sensitive information. This incident underscores the critical need for enhanced security measures in workplace collaboration tools.
The Walt Disney Company recently experienced a massive data breach after hackers infiltrated their Slack channels. The breach has resulted in the exposure of sensitive details related to ad campaigns, studio technology, and interview candidates, as reported by the Wall Street Journal.

The hacker group, NullBulge, has claimed responsibility for this attack. They announced on their blog that they have released over one terabyte of data from Disney’s Slack channels. The leaked data includes computer code and information on unreleased projects, spanning back to at least 2019. It covers a range of discussions about managing Disney’s corporate website, software development, and job applicant evaluations.
Speculations on the Method
Cybersecurity experts suggest that hackers might have breached Slack accounts by exploiting stolen or leaked API keys. Rahul Sasi, CEO of CloudSEK, pointed out that developers often integrate Slack into their automation tools, and in doing so, they sometimes accidentally leak these keys on code-sharing sites like GitHub or API platforms like Postman.
“For example, in the Disney leak, hackers gained access to public chat rooms. This occurred because Slack API keys, by default, typically have access to public Slack rooms,” Sasi explained.
While it is still too early to determine the exact cause of the breach, experts believe that weak passwords, phishing, and social engineering are unlikely to have compromised multiple Slack channels simultaneously.
Chandrasekhar Bilugu, CTO of SureShield, suggested that security misconfigurations or weaknesses in third-party integrations that Slack allows might be the most likely cause. “Whatever the reason, the attackers seem to have exploited the vast amount of data stored indefinitely by Slack’s Data Storage and Retention policy,” Bilugu said.
Mitigation Strategies in the Spotlight
This incident brings to light the urgent need for stronger security in workplace collaboration tools. Improved monitoring and threat detection technologies are essential to prevent such extensive data breaches.
“There are behavioral analytics tools that can be employed to enable organizations to establish baseline patterns of user and system behavior,” Bilugu said. “With continuous monitoring, deviations from normal activities can be flagged to detect potential data exfiltration and unauthorized access to sensitive information.”
Companies can also utilize Data Loss Prevention (DLP) solutions to prevent the unauthorized transfer of sensitive data outside the corporate network. These solutions use content inspection and contextual analysis to identify, monitor, and protect sensitive data. This includes encryption and policy enforcement.
“With the increasing adoption of cloud environments, organizations should consider advanced cloud security monitoring solutions,” Bilugu added. “These solutions provide visibility into cloud-based infrastructure, applications, and data. They offer real-time monitoring and threat detection tailored for cloud environments, helping to identify potential data breaches and exfiltration in cloud-based systems.”
In light of this breach, it is imperative that companies reassess and enhance their cybersecurity measures. The Disney data leak serves as a stark reminder of the vulnerabilities in current security practices and the need for continuous improvement in protecting sensitive information.
