Cornerstone Staffing Solutions, Inc., a human resources and workforce management provider, has reported a data breach to Oregon state authorities on September 11, 2026. The incident, which occurred on November 6, 2025, involved the exposure of various sensitive personal records.

The reported data types exposed in this breach include Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Telephone Number.

Exposure of these data types carries significant risks for affected individuals. A Social Security Number combined with a Date of Birth and Full Name can be used for identity theft, leading to fraudulent accounts, loans, or tax filings. Direct Deposit Account Details and Wage and Compensation Information could enable financial fraud, while Mailing Addresses and Telephone Numbers may be used for targeted scams.

Individuals who receive a breach notification from Cornerstone Staffing Solutions, Inc. should take immediate steps to protect their information. It is advisable to review financial statements and credit reports for any suspicious activity. Consider placing a fraud alert or freezing your credit with the major credit bureaus. Remain vigilant against unsolicited communications, particularly those asking for personal details.

Regularly checking your credit report helps identify unauthorized accounts or transactions. By taking these protective measures, you can reduce the potential impact of the exposed data.

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.
