Pertamina Listed by thegentlemen Ransomware Group

On July 31, 2026, the ransomware group known as thegentlemen listed Indonesian state-owned energy company Pertamina on its leak site, claiming to have exfiltrated more than 1.2TB of internal data. The group asserts it stole NDA files, HR data, employee records, user data, technical drawings, SCADA documents, bank statements, tax and legal files, photographs, and screenshots. As of this writing, Pertamina has not issued a public confirmation or breach notification, making this an unconfirmed claim originating solely from the threat actor’s leak portal.

Details from the Leak-Site Listing

The listing on thegentlemen’s leak site states that the data was taken during a ransomware attack on pertamina.com. It provides screenshots and a partial file tree but does not specify exactly when the intrusion occurred or how the attackers initially gained access. The group claims the total volume exceeds 1.2TB (1200 GB+) and includes sensitive operational and personal information. Because the primary disclosure comes from the ransomware group’s own site (tracked via ransomware.live), these assertions remain unverified by the company or any regulator.

The leak-site entry does not quantify the number of affected individuals. It simply lists categories such as HR data, employee data, user data, and technical SCADA documents. No sample records have been publicly released at the time of analysis, though the group typically escalates by publishing proof files or full datasets if demands are not met.

Why This Matters for You and Your Family

If your personal information was among the employee or user records taken, the exposure creates immediate risks. Energy-sector companies like Pertamina hold detailed HR files that often contain full names, national ID numbers, addresses, bank account details, tax records, and family information. When such data surfaces on a ransomware leak site, it can be quickly repackaged and sold on underground forums, increasing the chance of identity theft, tax fraud, or targeted scams against you and your household.

Even if you never worked directly for Pertamina, supply-chain and contractor data frequently ends up in these repositories. The incident therefore potentially affects a wide circle of individuals whose information was stored in the company’s systems.

Doxxing and Identity-Chain Risks

Leaked HR and employee data rarely stays isolated. Threat actors routinely combine it with other breaches to build detailed identity chains — linking an email address to a phone number, home address, family members, and even children’s online gaming accounts. A single exposed work email can lead to credential-stuffing attacks that compromise personal accounts, enabling doxxing, harassment, or financial fraud.

Public reporting on similar incidents shows that technical drawings, SCADA documents, and internal photographs can also be used to map organizational relationships and target specific employees or contractors for spear-phishing or blackmail. The cascading effect turns one corporate breach into a long-term personal privacy problem for entire families.

Thegentlemen Ransomware Group Track Record

Public reporting attributes thegentlemen as a relatively new double-extortion ransomware operation that emerged in late 2025. The group follows a now-standard playbook: initial access through phishing, remote desktop protocol exploitation, or compromised credentials, followed by extensive internal reconnaissance, data exfiltration, and then encryption. After deploying ransomware they wait a short period before listing victims on their leak site, using the public pressure of potential data publication to coerce payment.

Like many contemporary ransomware actors, thegentlemen does not always publish the full dataset immediately. They often begin with teaser samples and threaten to release the remaining volume — in this case over 1.2TB — on a set deadline. Their prior victims have spanned multiple sectors and geographies, indicating an opportunistic rather than strictly targeted approach.

What to do

• Run a DoxxScan to map every link between your email addresses, phone numbers, usernames, and real-world identity, including no-subscription cleanup of exposed records.
• Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next leak exposing your data is detected within hours rather than months.
• Immediately rotate any password you used for Pertamina-related services or accounts and enable 2FA using an authenticator app instead of SMS.
• Cover your entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often become the next link in doxxing chains.
• Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise require dozens of manual submissions.

The exposure of more than a terabyte of sensitive operational and personal data from a major national energy company underscores how quickly corporate incidents become personal ones. Even when confirmation from the victim organization is still pending, the prudent response is to assume your information may already be in circulation and act accordingly. DoxxScan by GalaxyWarden provides continuous monitoring across billions of records, AI-powered identity-chain mapping, and hands-on remediation by specialists — including protection for your family and children’s gaming accounts that are frequently targeted once credential leaks begin to cascade.
