If you are a customer of Jati Tinggi, here’s what is being claimed, and what it would mean for you.

Jati Tinggi was listed on The Gentlemen's leak site. The Gentlemen claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Jati Tinggi Listed by thegentlemen Ransomware Group

On March 26, 2026, Malaysian infrastructure company Jati Tinggi Group Berhad appeared on the leak site of the ransomware group known as thegentlemen. Internal files were allegedly exfiltrated during a ransomware attack on the publicly listed utilities engineering firm, exposing data that could affect employees, contractors, and anyone whose personal or business records were stored in the compromised systems.

What's Publicly Reported from Reporting

Public reporting indicates that Jati Tinggi Group Berhad, founded in 2003 and headquartered in Cheras, Selangor, was listed on thegentlemen’s leak portal. The company specialises in underground and overhead utilities for electricity transmission, fibre optic networks, drainage, sewerage pipelines, substation EPCC services, and street lighting. It operates as a subsidiary of Broad River Capital Sdn Bhd, employs between 51 and 200 people, and recently secured an RM80 million contract from Tenaga Nasional Berhad.

Available reporting describes the incident as a ransomware attack in which internal files were allegedly exfiltrated. The exact number of affected individuals remains unknown, and the precise data types have not been fully detailed in public summaries. The listing appeared on March 26, 2026 via the primary source at ransomware.live linking to thegentlemen leak site.

Why This Matters for You and Your Family

When a company that handles critical infrastructure contracts suffers a breach, the ripple effects reach ordinary people. Employees, former staff, suppliers, and even local residents whose utility records or contact details sit in those systems may find their information exposed. If your name, address, phone number, email, or national identification details were among the internal files, criminals can use them to attempt identity theft, phishing, or financial fraud against you and your family.

Credential leaks from corporate systems often spread quickly across the internet. Once your work email or password from this claimed breach appears on underground forums, it can be tested against your personal banking, shopping, and social media accounts. Children’s records linked to a parent’s work file are especially vulnerable because families rarely monitor them.

The Doxxing and Identity-Chain Implications

Ransomware incidents like this rarely stop at the initial leak. Exfiltrated internal files frequently contain spreadsheets linking employee names to personal emails, phone numbers, home addresses, and sometimes family member details. Attackers or subsequent buyers can chain this information with data from other breaches to build complete profiles. A single company email can lead to your social media handles, your children’s gaming usernames, and ultimately to physical addresses and family relationships.

These identity chains fuel doxxing campaigns, targeted phishing, and account takeovers. Gaming accounts belonging to you or your children are particularly at risk because the same passwords or recovery emails used at work are often reused for Steam, Roblox, or other platforms. Once one account falls, the rest can collapse in sequence.

The Group’s Publicly Known Track Record

Public reporting attributes the attack to thegentlemen ransomware group. The group emerged in recent years and has targeted organisations across multiple sectors with a playbook that typically involves initial access through phishing or exploited remote desktop services, followed by data exfiltration and deployment of ransomware. They then extort victims by threatening to publish stolen files on their leak site if demands are not met. Notable prior victims have included companies in manufacturing, logistics, and professional services, though details remain limited in open sources.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to remove what you can.
  • Rotate the password you used at Jati Tinggi or any related contractor accounts anywhere it is reused, and switch on two-factor authentication through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and 100+ platforms so the next leak exposing you or your family is caught in hours instead of months.
  • Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same addresses and recovery details.
  • Let the remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing your own accounts.

The incident shows that even companies providing essential public utilities can be hit without warning, leaving ordinary families to manage the consequences. Staying ahead requires more than changing one password. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and over 100 platforms, AI-powered identity-chain mapping that connects scattered online handles to real identities, and hands-on remediation by specialists who manage takedowns on your behalf. Its household coverage also protects children’s gaming accounts that frequently become entry points in doxxing chains after credential leaks like this one.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
