Triple X, also referred to as TripleX and triplex, is a relatively new ransomware and data-extortion threat actor. The group has been publicly associated with intrusions affecting organizations in the financial sector and professional services, including reported activity involving Bank Negara Indonesia, Bank of Baroda, and Henshaw Law. Available reporting ties the actor to incidents in Indonesia, India, and the United Kingdom, though some attributions remain based largely on the group’s own claims and similarities across operations rather than definitive public confirmation. The actor’s operations are characterized by theft and public exposure of large volumes of victim data, including internal documents, customer records, audit materials, and security-related documentation. In reported cases, Triple X has used a leak site to publish samples and directory listings as pressure tactics, indicating a data-theft-extortion model associated with ransomware branding. Publicly described victim data has included sensitive personal information and internal enterprise records, suggesting a focus on high-impact extortion through reputational and regulatory pressure. Observed tradecraft indicates initial access sufficient to reach internal document repositories or employee-accessible information stores, followed by collection and exfiltration of substantial datasets and post-compromise publication of proof material. In one publicly discussed case, the group claimed access stemmed from a weak password, but that assertion has not been independently confirmed. Reporting also indicates that employee email accounts and internal document environments may provide the type of access path relevant to the actor’s operations. High-confidence behaviors supported by available facts include initial access, exfiltration, post-exploitation activity, and extortion via leak-site publication. Public reporting does not provide enough corroborated detail to confidently assign a national sponsor or a broader malware-development lineage.

Conducting a ransomware attack and data breach against Henshaw Law, with claims of exfiltrating 1 terabyte of sensitive personal and legal documents.
Allegedly responsible for publishing a claimed 1 TB Bank of Baroda dataset on a Tor-based leak site, including sample documents and a browsable directory listing. The group also reportedly claimed a previous breach involving Indonesia’s Bank Negara Indonesia (BNI) and asserted that the initial compromise resulted from a weak password, though these claims remain unverified.
