SitusAMC Holdings Corporation Data Breach Notice (Oregon Attorney General)

The data breach at SitusAMC Holdings Corporation means that personal information belonging to 658,333 people is now outside the company’s control. The incident occurred on November 13, 2025. The company filed its notification with the Oregon Department of Justice on March 23, 2026 — an interval of 130 days, or roughly four and a half months.

Personal information that cannot be replaced

The filing lists personal information as exposed. In practice this almost always includes names combined with addresses, dates of birth, Social Security numbers, driver’s license numbers, or financial account details. Once this combination leaves a company’s systems it remains valuable to identity thieves for years. Unlike a credit card number, these details cannot be cancelled or reissued on demand.

No passwords or login credentials were exposed. That is genuinely good news. You do not need to change any password because of this incident, and the account itself is not at direct risk of takeover.

What the 130-day gap actually means for you

The time between the November 13, 2025 incident and the March 23, 2026 filing is the single most concrete fact in the record. Regulators require notification once an organisation has investigated and confirmed who was affected. A gap of this length is common when the company must review large volumes of records to identify exactly which Oregon residents were impacted. It does not tell us how long any unauthorised access lasted, only when the company formally reported the event.

How to know whether this filing includes you

SitusAMC Holdings Corporation is required to notify affected individuals directly, usually by mail to the last known address. If you have not received a letter, your information was most likely not part of the 658,333 records included in this filing. However, if you have moved since November 13, 2025, a letter may have gone to an old address. In that case contact SitusAMC directly to confirm whether your records were involved.

Why the exposed personal information still matters in 2026

Names paired with Social Security numbers or driver’s license data remain one of the most useful building blocks for identity theft. Criminals can use them to open new accounts, file fraudulent tax returns, or apply for government benefits in your name. Because none of these identifiers can be changed, the exposure creates a permanent risk that must be managed rather than eliminated.

The absence of any mention of medical information, passport numbers, or financial account numbers in the public categories means the filing does not establish that those specific data types were taken. Only the broad term “personal information” appears. Your own notification letter, if you received one, will list the exact fields that applied to you.

The limits of what this record can tell us

This filing does not disclose how the incident occurred, whether the actor was external or internal, or how long any unauthorised access continued. It also does not state which exact data fields beyond the general category of personal information were taken from each individual record. Those details remain outside the public notification.

Practical steps that address this specific exposure

• Place a fraud alert or credit freeze with the three major credit bureaus immediately. This is the single most effective way to stop new accounts from being opened in your name using the exposed personal information.
• Monitor your credit reports weekly for the next 12 months. Look for accounts or inquiries you do not recognise. Free weekly reports are available from AnnualCreditReport.com.
• File your taxes early and respond quickly to any IRS notices. Fraudulent tax returns filed with a stolen Social Security number are a common consequence of this type of breach.
• Review Explanation of Benefits statements from health insurers even if medical data is not listed in the filing. Medical identity theft can still occur when names and dates of birth are available.
• Keep the notification letter you received. It contains specific contact information for SitusAMC’s dedicated breach response team and any free credit monitoring offered.

The core reality is straightforward: your personal information is now in unknown hands and cannot be taken back. The risk is real but manageable. By focusing on credit monitoring, fraud alerts, and early detection of misuse, you retain the ability to limit the damage long after the 130-day notification clock has stopped.
