American Piping & Boiler Co, a company based in Kapolei, Hawaii, has reported a data security incident to the New Hampshire Attorney General. The company says unauthorized access to its computer network may have exposed Social Security numbers and government ID numbers. Companies that hold this information are responsible for protecting it.
American Piping & Boiler’s Data Breach Investigation
American Piping & Boiler Co, which the filing calls APB, is located at 491-335 Kauhi Street in Kapolei, Hawaii. The public account of the incident comes from a notice sent to the New Hampshire Attorney General on October 16, 2026 by the law firm Pierson Ferdinand LLP, along with a sample of the letter sent to affected people. The company’s own public statement about the incident was not found in the sources reviewed for this page.
According to the notice, APB experienced an IT security incident on or around February 15, 2026, involving unauthorized access by a third party to its computer network. The company says it activated its incident response plan right away and engaged experienced cybersecurity advisors. It says the network was remediated and secured, and that an investigation was then started to confirm how far the unauthorized activity went.
The investigation determined that certain client files containing personal information could have been compromised. The notice says the personal information of affected people could include driver’s license numbers, state ID numbers, Social Security numbers and names. It adds that the impacted data elements vary for each individual, so not every person had every item involved.
The sample letter to affected people gives a similar account. It says APB discovered an unauthorized third-party compromise of its network environment on or around February 15, 2026, secured and remediated the compromise, and engaged additional experts to confirm the security of its environment and to carry out a digital forensic investigation. The letter says the company has no indication that any information has been or will be misused.
The notice reports that one New Hampshire resident was notified by mail on October 16, 2026. That is only the New Hampshire count. The filing does not give a total for all states, and this page does not estimate one. Because the files in question are described as client files, the affected people could include customers of the company as well as others, though the filing does not specify who they are.
APB says it offered complimentary credit monitoring and identity protection services for twelve months through TransUnion to the people it notified, and that it is not aware of anyone experiencing fraud as a result of the incident. It also says it worked with experts to investigate how the incident happened and to take remedial and hardening steps that improve its network security and data privacy.
There is a long gap in this timeline. The incident dates to February 15, 2026, but the notice to the New Hampshire Attorney General is dated October 16, 2026, about eight months later. The filing does not explain the interval, although forensic review of files to identify whose information they contain is often slow. The notice does not name the person or group responsible and does not say how the intruder first got in.
Driver’s license numbers, state ID numbers and Social Security numbers are a sensitive combination. Together with a name, they can be enough to open accounts, apply for credit, file false tax returns or pass identity checks in someone else’s name. Unlike a card number, a Social Security number cannot easily be replaced, so the risk from exposure can last for years.
Small and mid-sized businesses are frequent targets of network intrusions because they often have limited security staff while still holding records on clients and employees. The sample letter itself observes that incidents of this kind have become commonplace and that organizations of all sizes are affected. That is general context and is not a finding about how the intrusion at APB happened.
If you received a letter from APB, keep it and use only the contact information printed in it. Scammers sometimes follow publicized incidents with fake calls or messages that claim to come from the affected company. The details of your own letter control over anything general on this page.
