National Defense Corp Listed by Interlock Ransomware Group

On February 24, 2025, the ransomware group known as interlock added National Defense Corp to its public leak site, claiming that it had exfiltrated internal files from the Wisconsin-based ammunition manufacturer also known as AMTEC.

What Public Reporting Shows

Public reporting indicates that AMTEC produces lethal and non-lethal ammunition, explosives, and cartridges primarily for military and law enforcement customers. The company is the largest global volume producer of 40mm Grenade Ammunition and Fuzing. Its headquarters are in Janesville, Wisconsin, and its manufacturing processes include precision assembly, explosive loading, metal forming, plating, and primary explosive production.

Available details state that the incident involved a ransomware attack in which internal files were exfiltrated. The number of individuals whose personal information may have been exposed remains unknown. No specific deadline for ransom payment has been publicly confirmed in the initial listing.

Why This Matters for You and Your Family

When a defense contractor’s internal files appear on a ransomware leak site, the information inside can include employee records, vendor contracts, email correspondence, and other documents that contain names, addresses, dates of birth, Social Security numbers, and contact details. If you or anyone in your family has ever worked at AMTEC, done business with the company, or had records stored in its systems, your personal data may now be in the hands of criminals.

Credential leaks from corporate networks frequently spread far beyond the original victim. Passwords, email addresses, or security-question answers stolen here can be used to compromise personal accounts you use at banks, health insurers, schools, or online retailers. Children’s school records, gaming logins tied to family email addresses, or shared household accounts can quickly become part of the same exposure chain.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at posting a single company’s files. Once personal records surface, they are often cross-referenced with data from earlier breaches to build detailed profiles. A seemingly minor document listing an employee’s home address, phone number, and child’s name can link to gaming accounts, social-media handles, and family photos. This identity-chain process turns one corporate breach into long-term personal exposure that can lead to targeted phishing, account takeovers, or physical threats.

Gaming accounts belonging to you or your children are especially vulnerable because they frequently reuse credentials from work or school environments. A password exposed in an AMTEC file can unlock an Xbox, PlayStation, or Roblox account that contains billing information, chat logs, and linked email addresses, giving attackers additional material to expand the doxxing chain.

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 this claimed breach connects to.
• Rotate any password you used at AMTEC or any related vendor system, then enable two-factor authentication through an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next exposure of your information is caught in hours rather than months.
• Cover the entire household with DoxxScan family protection that includes dependents and children’s gaming accounts, which often chain back to the same addresses and emails stolen in corporate incidents.
• Let remediation specialists handle takedown requests for any personal records that surface on data-broker or leak sites so you do not have to negotiate directly with operators.

The incident demonstrates that even companies supplying critical military components can have their internal data exposed without warning.
