quantummarketing-group.com Listed by Settra Ransomware Group

If you are a customer of quantummarketing-group.com, here’s what is being claimed, and what it would mean for you.

— from Settra’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
quantummarketing-group.com Listed by Settra Ransomware Group

Settra has listed quantummarketing-group.com on its leak site, claiming the company was hit by ransomware on 13 August 2026. The company has not publicly confirmed the claim as of writing.

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 a leak-site listing actually establishes

Settra, like most ransomware crews, publishes company names on dark-web leak sites to pressure victims into paying. The listing itself is simply a claim made by the attacker. It provides no independent proof that any breach occurred, that data was taken, or that the files described even exist. Many such listings later turn out to be recycled from older incidents, exaggerated, or entirely fabricated when the target refuses to pay.

Real confirmation would require the company to issue a public statement, regulators to announce an investigation, or affected individuals to receive direct notification letters. None of those have happened here. The record names no categories of information and does not state how many people, if any, were affected. Everything beyond the bare listing remains unverified.

Why this pattern keeps repeating

Ransomware groups continue to use leak-site listings as a standard pressure tactic even when independent verification is absent. The business impact of being named publicly often exceeds the technical harm of the alleged breach itself. For you as a customer, this means you will see more of these claims in the coming years, many of which will never receive official confirmation.

The uncertainty is the practical reality. You cannot wait for perfect information before acting, yet you also cannot treat every unconfirmed listing as a guaranteed catastrophe. The rational response sits between those extremes: tighten the credentials that matter most, monitor for follow-on abuse, and recognise that the absence of a direct notification letter from the company usually (though not always) indicates your records were not in the claimed set.

When a letter is the only reliable check

The organisation is required to notify affected individuals directly, typically by post to the address it holds. If you have not received such a letter, it is likely your information was not included. However, letters can go to old addresses, get lost, or arrive late. Because the incident date is 13 August 2026, anyone who has moved since then should contact Quantum Marketing Group directly to confirm whether their records were involved.

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.
