Direct download links and personal sample values are not reproduced here. ### IOCs & identifiers Identifiers directly visible or supported by the supplied material. These support correlation and do not independently verify the dataset claim. | Type | Identifier | Source | | ------------------------- | ----------- | ------------ | | Actor handle | ChimeraZ | Screenshot 1 | | Named organization domain | isep\[.\]fr | Screenshot 1 | The domain identifies the organization named in the claim, not malicious infrastructure. The source screenshot states that the actor uses Session rather than Telegram, but no Session ID is visible in the supplied capture. No malware hash, Tox ID or attacker-controlled IP address is visible. Direct download mirrors shown in the source material are intentionally not reproduced here. ### Mapped techniques **Claimed** identifies behavior explicitly described by the actor. **Inferred** identifies an analytical mapping supported by the supplied material. Neither label means the activity has been independently verified. - Collection [T1213.006](https://attack.mitre.org/techniques/T1213/006/) [Data from Information Repositories: Databases](https://attack.mitre.org/techniques/T1213/006/) Inferred The listing presents structured user datasets containing student or employee identity and contact information. The supplied material does not reveal how the data was obtained or independently establish unauthorized access to ISEP systems. ### Potential impact If authentic, the claimed dataset could expose **student or employee names, institutional email addresses, internal identifiers, location information and account-status metadata**. The combination could support targeted phishing, impersonation or other social-engineering activity involving ISEP users. ### Status Unverified Dark Web Informer has **not independently verified** the dataset's authenticity, source, completeness, 5,091-line count, 5,088-person count, sample contents or current availability.
