If you are a customer of bm.co.th, here’s what is being claimed, and what it would mean for you.

Bangsaen Mahanakorn Company Limited and affiliated companies of Bangsaen Mahanakorn

— from LockBit’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.
bm.co.th Listed by lockbit3 Ransomware Group

On October 6, 2023, Bangsaen Mahanakorn Company Limited and its affiliated companies appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack on the Thai firm bm.co.th. The disclosure does not specify the number of records affected or the exact types of documents stolen.

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.

Primary Disclosure Details

The LockBit 3.0 leak page, mirrored on ransomware.live, states that data was taken from Bangsaen Mahanakorn and related entities. It lists the victim under the entry dated October 6, 2023, and claims successful exfiltration of internal files. The notification does not quantify the volume of data or name specific file types such as customer databases, employee records, or financial spreadsheets. No ransom amount or payment deadline is detailed in the public listing.

LockBit 3.0 operators typically publish samples or file trees as proof before moving to full data release if demands are unmet. In this case the listing remains active, indicating the negotiation window has likely closed or is nearing its end.

Why This Matters for You and Your Family

When a company like Bangsaen Mahanakorn suffers a ransomware breach, the people whose information sits in those internal files face direct risk. If you have done business with bm.co.th, applied for a job there, or had any interaction that placed your name, address, phone number, email, or government ID in their systems, that information may now sit on a dark-web server controlled by extortionists. Your family members could be exposed through the same records, especially if joint accounts, shared addresses, or dependent information was stored.

Even when exact record counts remain unknown, the pattern is consistent: ransomware groups steal anything of value. The exposed data can fuel identity theft, loan fraud, or targeted phishing campaigns months or years later.

Doxxing and Identity-Chain Implications

Stolen internal files often contain spreadsheets that link personal details to usernames, email addresses, and phone numbers. Once attackers or data resellers possess these connections, they can map your online handles to your real-world identity. A single leaked email from this claimed breach can unlock other accounts where the same password was reused, creating a cascading doxxing chain that reaches social media, gaming platforms, and financial services.

Credential leaks like this one frequently surface in subsequent dumps, allowing criminals to attempt account takeovers on services you use every day. Children’s gaming accounts tied to a parent’s email or home address are especially vulnerable because young users rarely enable strong protections. The result can be full identity exposure that affects credit scores, employment background checks, and personal safety.

LockBit 3.0 Track Record

Public reporting attributes the LockBit ransomware family’s first appearance to 2019. The group rebranded as LockBit 3.0 in early 2023 after releasing new tooling and a more aggressive extortion model. Notable prior victims include numerous healthcare providers, manufacturing firms, and logistics companies across Europe, North America, and Asia. 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 ransomware. LockBit operators then demand payment while threatening to publish sensitive files on their leak site if the victim refuses. They have repeatedly shown willingness to follow through on those threats.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real identity so you can see exactly what this claimed breach connects to.
  • Rotate any password you used at bm.co.th or any Bangsaen Mahanakorn service, then enable 2FA through 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 exposure of your information is caught and acted on within hours rather than months.
  • Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same breached addresses or parent emails.
  • Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise consume hundreds of hours of your own time.

The Bangsaen Mahanakorn breach is a reminder that ransomware operators continue to target organizations that hold ordinary people’s information. Taking concrete steps now limits how far the stolen data can travel. Start your DoxxScan trial and let its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation specialists, and full household coverage—including children’s gaming accounts—work on your behalf before the next wave of abuse begins.

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.
