yankey.com.tw Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On October 2, 2021, the domain yankey.com.tw appeared on a leak site associated with the ransomware group lockbit2. The listing indicated that internal files had been taken from the organisation, though the number of people affected and the precise contents of any exfiltrated material remain undisclosed in public reporting.

The incident is one of many in which organisations are named on ransomware leak sites. Its significance lies in the potential exposure of internal records held by a Taiwanese entity and in the continuing use of data theft as leverage in ransomware operations.

What happened

yankey.com.tw was added to the lockbit2 ransomware leak site on October 2, 2021. The group claims to have stolen internal data during a ransomware attack. No further details on the timing of the intrusion, the volume of data taken, or the method of initial access have been made public. The number of individuals whose information may be involved is also unknown.

Who is lockbit2?

Lockbit2 is a ransomware operation that emerged in 2019 and gained prominence through its use of an affiliate model, in which separate actors deploy the ransomware and share proceeds with the core group. The operation is known for encrypting victim systems and, in many cases, exfiltrating data before encryption. It maintains a leak site where it lists organisations that have not met its demands, publishing samples or directories of stolen files as a form of pressure. The group has been linked to hundreds of incidents worldwide across multiple sectors.

Who is yankey.com.tw?

yankey.com.tw is a Taiwanese organisation operating under a .com.tw domain. Entities of this type typically maintain internal business records, client or supplier information, financial documentation, and operational systems. A breach affecting such an organisation can expose data that is not normally visible to the public and that may relate to both the organisation’s own activities and the parties with which it conducts business.

What data was at risk

The only information released publicly states that internal files were exfiltrated. The specific categories of data, file counts, or time periods covered by the claimed theft have not been disclosed. Organisations in this sector commonly hold records such as contracts, employee details, financial statements, and technical documentation, but it is not confirmed whether any of these were among the material taken in this case.

What's at stake

Exposure of internal files can create operational and reputational consequences for the affected organisation, including the possible disclosure of confidential business arrangements or technical information. For any individuals whose details appear in those files, risks may include targeted fraud or misuse of personal or financial information. The absence of Reported Details on the data types involved means the exact scope of these risks cannot yet be assessed from public sources.

If your data was in this claimed breach

Monitor accounts associated with yankey.com.tw for unusual activity and review any direct communications from the organisation. Use strong, unique passwords and enable multi-factor authentication where available. Individuals can run a free exposure scan of their email address against known breach data sets to check for appearances in previously published records.
