Facebook Users
This week’s Cyber Intelligence House, Leak of the Week highlights a breach involving the personal data of millions of Facebook users across multiple countries.
In June 2025, a dataset was shared on a private Telegram channel known as Data World All, containing documents with personal information sourced from public and private Facebook records. Upon analysis, 97 files totaling 713 MB were found leaked.
The exposed dataset includes identifiable user information such as full names, social media profile links, job titles, contact numbers, and physical addresses, raising significant privacy and profiling concerns.
Cyber Intelligence House Implications Analysis
For Individuals:
– Exposure of names, locations, and phone numbers increases vulnerability to targeted phishing and impersonation.
– Public linkage of profiles to job titles may lead to professional or reputational risk.
– Risk of doxing or misuse of leaked identities for fraud or social manipulation.
For Facebook or Related Platforms:
– Breach of user trust in how publicly visible data can be scraped, compiled, and redistributed.
– Possible regulatory attention in jurisdictions with strict data privacy laws.
Increased brand risk if user data is misused in scams or malicious campaigns.
Supply Chain Risks:
– If leaked user data references known employers or organizations, this could lead to spear phishing attempts, targeted impersonation, or the abuse of organizational relationships for further compromise.
Cyber Intelligence House Recommendations:
– Notify users tied to leaked data points, where feasible, especially if job roles or phone numbers are exposed.
– Encourage privacy audits: Users should review profile visibility and limit exposure of sensitive data.
– Enhance monitoring: Platforms should track unusual activity involving exposed profiles or contact points.
– Report abuse: Coordinate with platform trust and safety teams to disrupt continued sharing of the dataset.
