InfoMontreal Listed by sinobi Ransomware Group

On February 5, 2026, the Canadian company InfoMontréal appeared on the leak site of the sinobi ransomware group, with internal files exfiltrated during a ransomware attack now publicly listed for anyone to download.

What's Publicly Reported from Reporting

Public reporting indicates that sinobi posted details of the InfoMontréal breach on its dark web leak site. The listing includes exfiltrated internal files, though the exact volume of data and the specific number of people affected remain undisclosed. InfoMontréal provides business services in the Montreal area; the company has not yet issued a public statement confirming the incident. The ransomware group typically uses these postings to pressure victims into payment after initial encryption and data theft.

Why This Matters for You and Your Family

When a company that handles business records or client information is breached, the ripple effects often reach ordinary people. Your name, address, phone number, email, or financial details may sit inside those internal files even if you never directly signed up with InfoMontréal. Once that information leaves a corporate network, it can be sold, traded, or used to target you with identity theft, phishing, or harassment. For families, a single exposed record can link parents and children through shared addresses or phone numbers, multiplying the risk.

The Doxxing and Identity-Chain Implications

Ransomware leaks like this one frequently serve as the starting point for larger doxxing campaigns. Attackers combine the newly released corporate files with data from earlier breaches to build detailed profiles. A work email from the InfoMontréal files can be matched to a personal account, a gaming username, or a child’s online handle. These connections create an identity chain that lets criminals move from one account to the next. Credential leaks of this nature often cascade into account takeovers on gaming platforms, social media, and email, exposing your family’s private conversations, locations, and photographs.

Sinobi Group’s Known Track Record

Public reporting attributes the sinobi ransomware group with operations that emerged in recent years. The group follows a classic double-extortion playbook: it encrypts victim systems, exfiltrates sensitive files, then threatens to publish the data unless a ransom is paid. Notable prior victims have included organizations across North America and Europe, though exact details vary by incident. Sinobi typically posts samples or full datasets on its leak site after a deadline passes, aiming to inflict reputational damage and encourage payment.

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 the InfoMontréal files could connect to.
• Rotate any password you used at InfoMontréal or any related business service, then enable 2FA through an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak exposing you or your family is caught in hours rather than months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts, which often become targets when credential leaks cascade into doxxing chains.
• Let remediation specialists handle takedown requests across data brokers and exposed profiles while you focus on securing your own accounts.

The InfoMontréal breach is a reminder that corporate ransomware incidents quickly become personal when names and contact details escape into the open.
