475 GB Harita Group Data Breach Leaked on DarkForums.st

Data Breach Summary

A massive 475GB data breach targeting Harita Group, a major Indonesian conglomerate, was recently exposed on Darkforums.st by a user identified as clobelsecteam under the alias Sadboy. The leak, posted in September 2025, contains over 99,000 corporate email addresses and extensive internal data.

Harita Group operates in critical sectors including nickel mining, bauxite, coal, ferronickel smelters, alumina refineries, logging, and palm oil plantations. The leaked dataset may significantly compromise employee privacy and internal operations.

The breach was made public on a dark web marketplace, increasing its potential exposure to threat actors and cybercriminals.

Where and How?

The data was distributed through a popular cybercrime forum, Darkforums.st, a known hotspot for trading and leaking sensitive corporate data. Although the exact method of breach is yet unknown, the volume and sensitivity of the leaked files suggest a serious security lapse within Harita’s infrastructure or third-party partners.

The forum post specifically mentions company ties to Glencore International, a Swiss multinational with a history of corruption scandals, potentially highlighting broader risk vectors across Harita’s network.

Company Data Breach History

There are no previous public reports of data breaches involving Harita Group. However, multiple investigations have exposed the company’s involvement in environmental damage and undisclosed chromium-6 (Cr6) contamination in Indonesian waters—raising further concerns about the company’s transparency and internal controls.
