Mosley Glick O’Brien, Inc. Listed by bianlian Ransomware Group

On March 4, 2025, Mosley Glick O’Brien, Inc., a certified public accounting firm based in Toledo, Ohio, appeared on the leak site of the BianLian ransomware group. The listing indicates that internal files were exfiltrated during a ransomware attack on the company, which serves businesses, start-ups, non-profits, and individuals across multiple states and industry sectors including construction, manufacturing, transportation, and logistics.

What's Publicly Reported from Reporting

Public reporting on the BianLian leak site describes the incident as a ransomware attack in which attackers gained access to the firm’s network and removed internal documents. The exact number of people whose information was taken remains unknown. Available details confirm that Mosley Glick O’Brien, Inc. is the victim, the data consists of internal files, and the listing was published on March 4, 2025. No additional specifics about the volume or exact types of records have been released by the firm or the attackers.

Why This Matters for You and Your Family

If you or anyone in your household has worked with Mosley Glick O’Brien or any of its clients, your personal or financial information may now sit in an attacker’s archive. Accounting firms routinely handle tax returns, Social Security numbers, bank account details, income statements, and business records that contain addresses, phone numbers, and dates of birth. Once that material leaves the firm’s control, it can surface in fraud schemes, identity theft attempts, or be sold quietly on underground forums. Even if your name is not on the client list, family members or dependents whose information was shared during tax preparation or financial planning could be exposed.

The Doxxing and Identity-Chain Risks

Stolen internal files often contain more than numbers. They can include email addresses, usernames, notes about family situations, and references to children’s accounts or gaming handles used for communication. These fragments allow attackers to build identity chains that link your professional life to personal online activity. A credential found in one document can be tested across email, banking, and gaming platforms. Public reporting indicates that such cascades frequently lead to account takeovers, doxxing, and extortion attempts aimed at the individual rather than the original company. Gaming accounts belonging to you or your children are especially vulnerable because the same passwords or recovery emails are often reused.

BianLian’s Publicly Known Track Record

Public reporting attributes the attack to the BianLian ransomware group. The group emerged in 2022 and has targeted organizations across healthcare, finance, legal, and professional services sectors. Notable prior victims include hospitals, manufacturing companies, and other accounting or consulting firms. Their typical playbook involves initial access through phishing or exploited remote desktop credentials, followed by exfiltration of sensitive files, deployment of ransomware to encrypt systems, and then publication of stolen data on their leak site when demands are not met. Extortion pressure is applied directly to the victim organization, with threats to release client and employee information if payment is refused.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what chains back to the Mosley Glick O’Brien breach.
• Rotate any password you used at the accounting firm or with its client portals anywhere it has been reused, and switch to 2FA through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours instead of months.
• Cover the household with DoxxScan family protection that includes dependents and children’s gaming accounts, which often become the next link in doxxing chains after credential leaks like this one.
• Let remediation specialists handle takedown requests for any exposed personal records that surface on data broker sites or underground marketplaces.

The incident shows that even established professional service firms can become gateways to personal exposure. Taking concrete steps now limits how far attackers can travel down the identity chain created by this claimed breach. Start your DoxxScan trial and use its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage to protect yourself and your family—including any gaming accounts that could be swept up in follow-on attacks.
