AT Solution Listed by sinobi Ransomware Group

On October 1, 2025, AT Solution Limited appeared on the leak site of the sinobi ransomware group, with the attackers claiming to have exfiltrated internal files from the Hong Kong-based mobile and web development company.

Confirmed Facts from Reporting

Public reporting on the sinobi leak site indicates that AT Solution’s internal documents were taken during a ransomware incident. The company, which specializes in innovative mobile and web services, open-source solutions, and service-oriented architecture, has not publicly confirmed the breach or disclosed the volume of data involved. Available reporting describes the exposed material as internal files, though the exact number of people whose information appears in the files remains unknown. No customer records, financial databases, or specific categories such as names, addresses, or payment details have been independently verified in the initial leak announcement.

Why This Matters for You and Your Family

When a company like AT Solution suffers a breach, anyone who has ever used its mobile apps, web platforms, or consulted its services may have personal information sitting in those internal files. Internal files often contain project details, contact lists, email addresses, phone numbers, and sometimes development credentials that can be repurposed by criminals. For ordinary families this means your data could surface in follow-on attacks even if you never directly signed up with the firm. Children’s information sometimes appears in family-linked accounts or test data, turning a corporate incident into a household risk.

The Doxxing and Identity-Chain Implications

Stolen internal files frequently serve as the first link in a doxxing chain. A single email or phone number taken from a development company can be correlated with gaming usernames, social-media handles, and school records. Once attackers map these connections, they can move from one account to the next, escalating from simple data exposure to full identity takeover. Credential leaks of this nature regularly cascade into gaming account compromises, where children’s profiles become targets because the same password or recovery email was reused across adult and family services.

Sinobi Ransomware Group’s Known Track Record

Public reporting attributes the attack to the sinobi ransomware group. The group emerged in recent years and has targeted organizations across multiple sectors by gaining initial access, exfiltrating data, and then publishing samples on its leak site when victims do not pay. Its typical playbook combines ransomware encryption with public shaming, using the threat of full data release as leverage. Exact prior victim counts and technical details remain limited in open sources, but the group’s consistent use of leak sites matches the pattern seen in this October 1 listing.

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 chains back to the AT Solution files.
• Rotate any password you ever used on AT Solution’s platforms or related services, then enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next exposure of your information is caught within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become the weakest link in these identity chains.
• Let remediation specialists handle takedown requests and broker removals for any personal data that has already surfaced from this or linked incidents.

The incident underscores that corporate data leaks now reach ordinary families faster than most people realize. Taking concrete steps today limits how far attackers can travel along the identity chain created by this breach. DoxxScan by GalaxyWarden delivers continuous monitoring across 15.4 billion breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.
