mjcelco.com Listed by blackbasta Ransomware Group

On March 19, 2024, manufacturing company MJ Celco was listed on the leak site of the Black Basta ransomware group. The listing claims that roughly 1.2 terabytes of the Illinois-based metal-stamping firm’s internal files were exfiltrated during a ransomware attack. Anyone whose personal information appears in employee folders or whose projects, drawings, or financial records touch MJ Celco may now face heightened risk of identity theft and targeted fraud.

Reported Details from the Listing

The Black Basta leak page states that data taken from www.mjcelco.com includes projects, engineering drawings, financial data, and employees’ personal folders. The company, located at 3900 Wesley Terrace, Schiller Park, IL 60176, employs 225 people and operates 255,000 square feet of manufacturing space. The disclosure does not specify how many individuals are affected or list exact record counts. It simply asserts that the stolen archive totals approximately 1.2 TB and warns that the files will be published if the company does not meet the group’s demands.

Why This Matters for You and Your Family

When a manufacturer’s internal network is breached, the exposure rarely stops at corporate secrets. Employee personal folders frequently contain scanned driver’s licenses, tax forms, direct-deposit details, and family contact information. If your name, address, date of birth, or Social Security number was stored in one of those folders, it can be combined with data from earlier breaches to build a complete profile. Criminals use that profile to open accounts, file fraudulent tax returns, or impersonate you with creditors. Even if you never worked at MJ Celco, vendors, customers, and their families can be swept up when financial spreadsheets and project files containing names and addresses are dumped publicly.

Doxxing and Identity-Chain Risks

Leaked employee data often acts as the first link in a longer doxxing chain. An email address from an MJ Celco folder can be cross-referenced with gaming usernames, social-media handles, and phone numbers found in other breaches. Once attackers map those connections, they can hijack accounts, demand ransom from relatives, or publish personal details to harass victims. Credential leaks like this one routinely cascade into account takeovers on Steam, Roblox, Discord, and other platforms used by children and teenagers. A single exposed workplace folder can therefore endanger the entire household’s digital footprint.

Black Basta’s Known Track Record

Public reporting attributes the first Black Basta ransomware attacks to early 2022. The group has since hit hospitals, manufacturers, financial firms, and local governments across North America, Europe, and Australia. Their typical playbook begins with initial access gained through compromised remote-desktop credentials or phishing, followed by rapid lateral movement, data exfiltration, and deployment of ransomware that encrypts systems. After encryption they publish a sample of stolen files on their Tor leak site and pressure victims with both encryption and public-data-release threats. The MJ Celco listing follows this exact pattern.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
• Rotate any password you used at MJ Celco or any related vendor account, then enable 2FA through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and extortion sites on your behalf while you focus on securing your own devices and accounts.

The speed with which ransomware groups move stolen data onto leak sites leaves little room for delay. Treating this incident as a prompt to lock down every linked identity is the most practical defense. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes children’s gaming accounts.
