osoftec.com Listed by m3rx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Osoftec.com has been listed by the m3rx ransomware group, which claims to have exfiltrated internal files. The incident was disclosed on 29 April 2026; an undisclosed number of people may be affected, and anyone who has data with the organisation should check for signs of exposure and change credentials or enable monitoring where appropriate.
What happened
On April 29, 2026, the ransomware group m3rx listed osoftec.com on its leak site. The listing states that 222 GB of data, contained in 113,000 files, was removed from the company. Public reporting describes the material as internal files taken during a ransomware attack. No further details on the timing of the intrusion, the method of access, or confirmation of data publication have been released.
Who is m3rx?
m3rx is a ransomware operation that has appeared in multiple public listings of compromised organisations. Groups of this type typically gain access through remote services, exploit unpatched systems, or use stolen credentials, then encrypt files and threaten to publish stolen material unless a ransom is paid. The listing of osoftec.com constitutes the group’s claim of responsibility; independent confirmation of the theft or of any subsequent data release has not been provided in available reports.
About osoftec.com
osoftec.com is the online presence of Optimization Software Technologies, LLP, an Indian technology company that develops software solutions intended to improve operational efficiency and profitability for client organisations. Firms in this sector routinely process client data, internal project files, financial records, and communications that can include personal identifiers of employees and customers.
What data was at risk
The listing refers to internal files without specifying their contents. Organisations of this type commonly store customer contact details, project documentation, employee records, and business correspondence. Because the precise categories of information have not been published, it is not possible to state which records, if any, were included among the 113,000 files.
The real-world impact
Individuals named in the files could face risks of targeted phishing, identity misuse, or unwanted disclosure of business relationships. The company itself may encounter operational disruption, regulatory scrutiny, and costs associated with investigation and remediation. At present, the absence of confirmed victim counts or published samples limits assessment of the scale of these consequences.
Were you affected?
Begin by monitoring official statements from osoftec.com and any notifications the company may issue to clients or staff. Change passwords for any accounts linked to the organisation and enable multi-factor authentication where available. Readers can also submit their email address to a reputable breach-checking service to determine whether it appears in previously published data sets from other incidents.

Publicly posted by m3rx — 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.
