Eastin Hotel Makkasan Bangkok was hacked Customers' financial and personal information has Listed by alphv Ransomware Group

If you are a customer of Eastin Hotel Makkasan Bangkok, here’s what is being claimed, and what it would mean for you.

Eastin Hotel Makkasan Bangkok was listed on Alphv's leak site. Alphv claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Eastin Hotel Makkasan Bangkok was hacked Customers' financial and personal information has Listed by alphv Ransomware Group

On July 12, 2023, the Eastin Hotel Makkasan Bangkok appeared on the leak site of the Alphv ransomware group. The listing states that the Thai hospitality company suffered a ransomware attack in which internal files were exfiltrated. The number of affected customers remains unknown, and the precise data elements contained in those files have not been detailed by the threat actor.

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 582 companies.

Reported Details from the Listing

The primary disclosure on the Alphv leak site indicates that attackers gained access to the hotel’s systems, encrypted data, and then published proof of the breach after the company did not meet their demands. The posting includes sample screenshots and file trees but does not quantify the volume of records or list specific categories such as credit-card numbers or passport scans. Public mirrors of the leak site, tracked by ransomware.live, state the incident was first published on 12 July 2023. No subsequent update from the hotel or Thai regulators has altered these core facts.

Why This Matters for You and Your Family

When a hotel you have stayed at loses control of internal files, the exposure can reach far beyond the front desk. Reservations often contain home addresses, phone numbers, email accounts, payment details, and sometimes copies of identification used at check-in. Even if the exact contents are not yet public, the mere confirmation that internal files were allegedly exfiltrated creates immediate risk for anyone who has visited the Eastin Hotel Makkasan Bangkok or its sister properties. Your family’s travel history, contact information, and financial breadcrumbs can be packaged and sold quietly on criminal forums long after the initial leak-site posting disappears.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at posting data on their leak site. Once internal files leave the victim’s network they frequently surface in smaller batches on Telegram channels, underground marketplaces, and infostealer logs. A single hotel booking can link your email address to a real-world location, travel dates, and companions—information that attackers chain with credential leaks from other breaches to build a complete identity profile. This chaining is especially dangerous for families because children’s names, school details, or even gaming usernames sometimes appear in family travel records. The result is a widening web of doxxing that can lead to targeted phishing, account takeovers, and physical stalking.

Alphv’s Publicly Known Track Record

Public reporting attributes the Alphv group, also known as BlackCat, with emerging in late 2021 after the shutdown of the REvil ransomware operation. The gang has since claimed responsibility for attacks on hundreds of organizations worldwide, including healthcare providers, manufacturing firms, and hospitality chains. Their typical playbook begins with initial access gained through compromised remote desktop credentials or phishing, followed by rapid lateral movement, data exfiltration, and deployment of custom ransomware. After encryption they wait a short period before publishing samples on their Tor-based leak site, then escalate pressure through distributed denial-of-service attacks and direct threats to publish sensitive customer data. The exact ransom demand made to Eastin Hotel Makkasan Bangkok has not been disclosed.

What to do

  • Rotate any password you have ever used when booking at the Eastin Hotel or any Eastin property, and enable 2FA with an authenticator app on every account where that password was reused.
  • Run a DoxxScan to map every link between your email addresses, phone numbers, travel handles, and real-world identity so hidden connections surface immediately.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught within hours rather than months.
  • Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same address or parental email.
  • Let remediation specialists handle data-broker takedown requests and opt-out processes on your behalf while you focus on securing day-to-day accounts.

The Eastin Hotel breach is a reminder that travel data is now prime currency for ransomware operators who move quickly from encryption to extortion. One listing today can become dozens of smaller leaks tomorrow. Starting your DoxxScan trial gives you continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping that links handles to real identities, hands-on remediation by specialists, and household coverage that includes children’s gaming accounts—practical defense for you and everyone who shares your name or address.

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.
