The Kurt J. Lesker Company, a global manufacturer and distributor of vacuum science technology, formally reported a data security incident to the Vermont Attorney General on September 16, 2026. This report indicates that unauthorized actors gained access to its network environment, leading to the compromise of sensitive personal data. The company's operations include supporting advanced research, semiconductor manufacturing, and aerospace engineering.

According to the official filing, the data exposed in this incident includes individuals' Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Direct Deposit Account Details, Tax Return Information, and Phone Number. This extensive range of information is often targeted by cybercriminals due to its value.

The exposure of these data types, especially Social Security Numbers and Direct Deposit Account Details, creates potential risks for identity theft, fraudulent financial activity, and targeted scams. Individuals whose Wage and Compensation Information or Tax Return Information were compromised may face risks related to tax fraud or unauthorized access to their financial profiles. This information, when combined, offers avenues for criminals to impersonate individuals or access financial resources.

Individuals who receive a breach notification letter from Kurt J. Lesker Company should consider taking several protective steps. It is generally recommended to monitor financial accounts and credit reports for any suspicious activity. Placing a fraud alert or security freeze on credit files with the major credit bureaus (Equifax, Experian, TransUnion) can help prevent new accounts from being opened in your name. Additionally, be cautious of unsolicited communications, as exposed phone numbers and names could be used in phishing or social engineering attempts. Changing passwords for online accounts, especially those related to finances or employment, is also a good practice.

This information is based on public filings made by Kurt J. Lesker Company with the Vermont Attorney General, serving as an official record of the reported data security incident.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
