Cosmos Hotel Group Listed by Malas Ransomware Group

On April 09, 2023, Cosmos Hotel Group appeared on the leak site operated by the malas ransomware group. The listing states that internal files were exfiltrated during a ransomware attack that leveraged a Zimbra vulnerability. The disclosure does not specify the number of people affected or list exact data types beyond the broad category of internal files.

Details from the Leak Site

The malas leak site entry, still accessible via the .onion link tracked by ransomware.live, states that Cosmos Hotel Group was listed as a defaulter after failing to meet the group’s demands. It explicitly notes the initial access vector as a Zimbra vulnerability and states that internal files were successfully exfiltrated. No sample data is publicly shown on the page, and the listing does not quantify records or name specific document types such as guest databases or employee spreadsheets. The disclosure indicates the company was given a deadline to pay or face full publication; that deadline has now passed.

Why This Matters for You and Your Family

When a hotel group’s internal files are stolen, the information inside often includes guest reservation details, contact information, payment records, and employee payroll or HR documents. Even though the exact contents remain unknown, any exposure of names, addresses, phone numbers, email addresses, or dates of birth creates immediate risks for the individuals named in those files. If you or your family have stayed at a Cosmos Hotel property, attended an event there, or worked for the company, your personal information may now sit in an attacker’s archive. That data can be sold quietly on underground forums long after the ransomware listing disappears.

The Doxxing and Identity-Chain Risks

Ransomware operators rarely stop at posting a single zip file. Once internal files leave the victim’s network they frequently surface in doxxing packages that link hotel guest records to social-media handles, family addresses, and children’s names. These chains allow criminals to move from one breach to the next, using a hotel booking email to reset passwords on shopping accounts, then using those accounts to obtain more precise location data. Credential leaks like this one cascade into account takeovers that can compromise your email, banking, and even gaming logins. Gaming accounts belonging to children are especially vulnerable because parents often reuse the same password or recovery email that appears in a hotel guest list.

What to Do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your data is caught in hours rather than months.
• Rotate any password you used when booking with Cosmos Hotel Group or any related service, replace it with a unique passphrase, and secure every account with 2FA through an authenticator app rather than SMS.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same address or recovery email.
• Let remediation specialists handle takedown requests across data brokers and extortion sites on your behalf while you focus on securing your own logins.

The malas group’s listing of Cosmos Hotel Group is a reminder that one compromised email server can expose thousands of ordinary travelers and employees to long-term identity abuse. Public reporting on similar incidents shows that data stolen in 2023 ransomware attacks continues to circulate years later. Start your DoxxScan trial today; its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage including children’s gaming accounts give you and your family a practical defense against the next wave of leaks. The earlier you map and lock down your exposed information, the less damage any future breach can do.
