Grant Production Testing Services Listed by Payoutsking Ransomware Group

If you are a customer of Grant Production Testing Services, here’s what is being claimed, and what it would mean for you.

Grant Production Testing Services was listed on Payoutsking's leak site. Payoutsking claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Grant Production Testing Services Listed by Payoutsking Ransomware Group

On February 24, 2026, Grant Production Testing Services appeared on the leak site of the payoutsking ransomware group. The Canadian oilfield services company, which provides well testing and production data solutions to energy operators, is claimed to have had internal files exfiltrated after a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, anyone whose personal or employment records passed through the company’s systems could be affected.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that payoutsking listed Grant Production Testing Services on its dark-web leak portal and began publishing stolen data. The exposed material consists of internal files exfiltrated during the ransomware incident. No confirmed total of records or specific categories of personal information have been publicly detailed, but files of this nature frequently contain employee names, contact details, addresses, financial information, and client-related records. The listing carries the typical extortion timeline seen in these incidents, although exact deadlines have not been independently verified.

Why This Matters for You and Your Family

When a company that handles operational data for the energy sector is breached, the ripple effects reach ordinary people. Employees, contractors, and even their family members can find their names, addresses, phone numbers, and dates of birth circulating on criminal forums. Once that information is loose, it can be combined with other leaks to build profiles used for identity theft, loan fraud, or targeted scams. Your family does not need to work in oil and gas for the consequences to reach you; shared addresses, joint accounts, or children’s records linked to an employee can pull an entire household into the chain.

Credential leaks like this one often cascade far beyond the original victim company. Passwords or email addresses reused across personal accounts become entry points for takeovers, turning a corporate breach into a personal nightmare.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
