Data exposed Internal files exfiltrated in ransomware attack

On April 29, 2026, Optimization Software Technologies, LLP, a technology solutions company based in India, appeared on the leak site of the m3rx ransomware group. The attackers claim to have stolen 222 GB of internal files containing 113,000 documents. Anyone whose personal or business data was stored with the company could now be exposed.

Confirmed Details of the Breach

Public reporting indicates the incident began as a ransomware attack on osoftec.com. The m3rx group exfiltrated data before encrypting systems or disrupting operations. The leaked material consists of internal files rather than a structured database of customer records. No confirmed list of affected individuals has been published, leaving many customers uncertain whether their information is among the stolen documents.

222 GB and 113,000 files represent a substantial volume of contracts, project documentation, employee records, and client communications. The company’s contact number, +91 9717385459, appears in public descriptions of the incident. As of now, m3rx has not posted samples or demanded a specific ransom from Osoftec.

Why This Matters for You and Your Family

When a vendor that handles operational or personal files suffers a breach, your information can surface in unexpected places. Tax documents, contracts containing addresses, phone numbers, or email addresses may have been stored with the company. Once exposed, that data can be sold or posted on underground forums.

Children’s information is often included in family-related project files or school-partnership records. A single leak can give attackers the starting point they need to target your household. The breach highlights how data you entrust to service providers can affect your family’s safety long after you stop working with them.

The Doxxing and Identity-Chain Risks

Stolen internal files frequently contain spreadsheets that link names, email addresses, phone numbers, and project details. Attackers use these connections to build identity chains that reveal far more than any single record suggests. A leaked work email can lead to personal accounts, and a home address in a contract can expose family members.

Credential leaks of this kind often cascade into gaming account takeovers. Children’s usernames, linked through shared family emails or phone numbers, become easy targets. Once an attacker controls a gaming account, they can harvest additional personal details or use it as leverage in harassment campaigns. Continuous monitoring across breach repositories helps catch these expanding chains before they reach your family.

m3rx Ransomware Group Track Record

Public reporting attributes the attack to the m3rx ransomware group. The group emerged in late 2024 and has targeted mid-sized companies across technology, manufacturing, and professional services sectors. Notable prior victims include software development firms and logistics providers whose internal documents were posted after failed ransom negotiations.

Their typical playbook involves initial access through compromised credentials or remote desktop vulnerabilities, followed by exfiltration of sensitive files. They then demand payment to prevent publication. If no payment is received, data is gradually released on their leak site in an effort to pressure the victim or attract secondary buyers. Exact success rates remain unclear from available reporting.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity so you can see exactly what this breach may have exposed.
  • Rotate any password you used at Optimization Software Technologies anywhere else it appears, and switch to 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next leak that touches your family is flagged within hours instead of months.
  • Cover the entire household with DoxxScan family protection, which includes children’s gaming accounts that often chain back to the same addresses and emails stolen in vendor breaches like this one.
  • Let remediation specialists handle data broker takedowns and removal requests so you do not have to chase every site yourself.

The incident shows that even companies you no longer actively use can put your family at risk months or years later. Taking concrete steps now limits how far attackers can travel down the identity chain created by this 222 GB leak. DoxxScan by GalaxyWarden delivers that continuous monitoring, AI-powered identity-chain mapping, and hands-on remediation by specialists, with coverage that extends to every member of your household.
