high severity October 28, 2025 · 3 min read Unverified claim — what this is

h*tel*ys*e*s.pl Listed by devman Ransomware Group

If you are a customer of h*tel*ys*e*s.pl, here’s what is being claimed, and what it would mean for you.

h*tel*ys*e*s.pl was listed on Devman's leak site. Devman claims to have stolen internal data. This is the group's claim, not a confirmed finding.

h*tel*ys*e*s.pl Listed by devman Ransomware Group

On October 28, 2025, the Polish hotel booking platform htelyses.pl appeared on the leak site of the devman ransomware group. The attackers published what they describe as 400,000 internal files stolen during a ransomware incident, exposing the personal and operational data of an unknown number of customers and employees.

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 582 companies.

Reported Details from Reporting

Public reporting indicates the devman group added htelyses.pl to its data-leak portal on October 28, 2025. The listing claims 400k internal files were exfiltrated after the company apparently declined to pay a ransom. Available reporting describes the exposed material as internal documents rather than a simple database dump, though the precise volume and sensitivity of customer records remain unconfirmed by the company itself. No independent verification of the full dataset has been published.

Why This Matters for You and Your Family

When a hotel booking site is breached, the records often contain names, home addresses, phone numbers, email addresses, dates of stay, and payment details. If you or anyone in your household has ever made a reservation through htelyses.pl, that information may now be in the hands of criminals. Hotel booking data is especially useful to attackers because it links real-world identities to travel patterns, family members, and financial information. A single leak like this can give thieves enough to attempt identity theft, phishing campaigns, or fraudulent bookings in your name.

Children’s information is sometimes included when families book together. A leaked family booking can reveal a child’s full name, date of birth, and even passport details if they were part of an international trip. Once that data circulates, it becomes harder to keep your family’s digital footprint private.

The Doxxing and Identity-Chain Risk

Stolen hotel records rarely stay isolated. Attackers routinely combine them with other leaks to build detailed profiles. A phone number from this claimed breach can be matched to gaming accounts, social-media handles, or school records. This creates an identity chain that leads from an old booking straight to your current life. Credential leaks of this kind frequently cascade into account takeovers on gaming platforms, where children’s usernames and passwords are reused. Public reporting shows these chains often end in doxxing, harassment, or demands for payment to delete the information.

Devman Group’s Known Track Record

Public reporting attributes the attack to the devman ransomware group. The group emerged in recent years and has targeted mid-sized companies across Europe, often focusing on sectors that hold customer travel or personal data. Their typical playbook involves gaining initial access, exfiltrating files, encrypting systems, then publishing samples on their leak site when the victim refuses to pay. Extortion follows a double-pressure model: both the threat of public exposure and the permanent loss of encrypted business data. Past victims listed on their portal include other hospitality and service providers, though exact success rates are difficult to verify from open sources.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity, then use the cleanup to break those connections.
  • Rotate any password you used on htelyses.pl and enable 2FA with an authenticator app on every account where that password was reused.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak that touches your family is caught in hours rather than months.
  • Cover the household with DoxxScan family protection, which extends to children’s gaming accounts that often chain back to the same addresses and credentials exposed in breaches like this.
  • Let remediation specialists handle takedown requests across data brokers and leak sites on your behalf while you focus on securing day-to-day accounts.

The incident is a reminder that data stolen today can surface months or years later in unexpected ways. One practical step can limit how far the chain reaches. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes your children’s gaming accounts.

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.
