On November 9, 2023, engineering consultancy Sinotech Engineering Consultants Inc. in Taiwan appeared on the leak site of the Alphv ransomware group. The listing states that internal files were exfiltrated during a ransomware attack. The company has not yet published a formal breach notification, so the exact number of people whose data may be exposed remains unknown.

Details from the Leak Site
The Alphv listing, still accessible via its onion address at the time of analysis, claims that attackers obtained internal company files after deploying ransomware. It does not specify the volume or exact categories of data taken, only that the material is sensitive and belongs to Sinotech. The disclosure gives no deadline for ransom payment or proof-of-exfiltration samples beyond the initial claim. Public records confirm Sinotech was founded in 1970 as a non-profit engineering consultancy that has worked on major infrastructure projects across Taiwan and overseas, including water resources, transportation, environmental planning, and power systems. This background means the stolen files could contain technical drawings, project bids, employee records, or partner contracts, though the listing itself does not detail contents.
Why This Matters for You and Your Family
When an engineering firm like Sinotech suffers a ransomware breach, the ripple effects reach ordinary people whose personal information sits in vendor files, employment records, or project documentation. If your name, address, national ID number, or contact details appear in any of those internal files, attackers or subsequent buyers can use them for identity theft, loan fraud, or targeted phishing. Families in Taiwan are especially exposed because national ID numbers and household registration data are frequently stored together in government-related engineering contracts. Even without a confirmed headcount, the high-severity label attached to the incident signals that the data is valuable enough for professional extortionists to advertise publicly.
Doxxing and Identity-Chain Risks
Exfiltrated internal files often contain spreadsheets that link employee names to personal emails, phone numbers, project roles, and sometimes family contact details for emergency purposes. Once these appear on dark-web markets, criminals can chain the information: an email from the breach leads to a reused password on a shopping site, which leads to a home address, which leads to children’s school records or gaming accounts. Gaming usernames and passwords are particularly vulnerable because kids frequently reuse credentials tied to a parent’s work email domain. The result is a complete identity map that can be sold or used for long-term extortion.
