martek co ltd. Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Martek Co Ltd. was listed by the Incransom ransomware group on April 10, 2026, after internal files were taken in a ransomware attack; the date of the intrusion itself has not been established. Individuals who may have had dealings with the company should review any notifications and change passwords or monitor accounts as a precaution.
Inside the incident
The listing appeared on April 10, 2026. Available information indicates only that internal files were taken and that the group associates the material with a volume of 700 gigabytes under nondisclosure terms. The date of the underlying intrusion, the method of access, the precise contents of the files, and any ransom demand or payment status are not disclosed. The number of people affected is recorded as unknown.
Who is incransom?
Incransom is a ransomware operator that has conducted multiple campaigns involving both file encryption and data exfiltration. The group maintains a leak site where it publishes samples or directories of material taken from listed organisations, using the threat of further disclosure to encourage payment. This approach aligns with tactics observed across several established ransomware groups that combine operational disruption with the release of sensitive internal documents.
Who is martek co ltd.?
Martek co ltd. is the organisation operating the domain martek.com.tw. Companies of this type typically manage commercial contracts, technical documentation, and client or partner information in the course of their operations. A breach involving internal files therefore carries implications for business relationships and any confidential material those files may contain.
What data was at risk
The listing states that internal files were exfiltrated. The entry references 700 gigabytes of material described as NDA-related, but the exact categories of information, file types, or individual records have not been confirmed beyond this description. Organisations in this sector commonly hold contract details, technical specifications, and correspondence; whether any such material appears in the exfiltrated set remains unverified.
Why it matters
Exposure of internal files can affect the confidentiality of business agreements and any personal or commercial data contained within them. For individuals or partner organisations referenced in the material, the primary concerns are potential misuse of contact details or contractual information. For the company itself, the incident adds to the operational and reputational consequences already associated with ransomware activity.
What to do if you're exposed
Individuals who believe their information may be involved should monitor accounts for unusual activity and consider changing passwords for any services linked to the affected organisation. Enabling multi-factor authentication where available provides an additional layer of protection.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
