Nanometrics Listed by qilin Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Nanometrics has been listed by the qilin ransomware group, with internal files reported to have been exfiltrated; the incident came to light on 19 April 2026 and the number of people affected remains undisclosed. Anyone who may have shared information with the organisation should check for any direct notice and take appropriate protective steps.
What happened
Nanometrics was added to the Qilin ransomware leak site on the reported date of 19 April 2026. The group states that internal files were taken during a ransomware attack. No information has been released on the date of the intrusion, the quantity of data involved, or whether any demands were issued or met. The number of individuals potentially affected remains unknown.
Who is qilin?
Qilin is a ransomware group that maintains a public leak site to publish data it claims to have stolen from targeted organisations. The group follows the pattern seen with other ransomware operations that use double-extortion methods: encrypting systems and threatening to release exfiltrated material if payment is not received. Its listings are presented by the group itself and are not independently verified in this case.
Nanometrics and its sector
Nanometrics is the organisation named in the listing. Details of its precise sector and operations are not provided in the available breach information. Organisations of this type routinely hold internal records generated by day-to-day business activities, and any unauthorised access to such material can affect internal processes even when the full scope of exposure is not yet known.
What data was at risk
The only data type referenced is internal files exfiltrated during the claimed ransomware attack. No further categories, file counts, or descriptions have been disclosed. Without additional confirmation, the exact contents of any material that may have been taken cannot be stated as fact.
Why it matters
Internal files can contain operational details whose release or misuse may create follow-on difficulties for the organisation and any individuals whose information appears in those records. When the volume and sensitivity of the material remain undisclosed, affected parties have limited ability to assess their own exposure or to take targeted protective steps.
Were you affected?
If Nanometrics holds records that include your information, monitor communications from the organisation for any official notices. Individuals can also review their own accounts for unusual activity and consider standard account-security measures such as changing passwords and enabling multi-factor authentication where available.

Publicly posted by qilin — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
