Bottom line: The publicly identified breach occurred at SitusAMC, a third-party real-estate finance and mortgage-services provider—not in the core banking systems of JPMorgan Chase, Citigroup or Morgan Stanley. SitusAMC said on March 17, 2026, that its forensic review and required consumer notifications were complete. The public record still does not identify how many customers of each bank were affected or confirm that particular data elements—such as Social Security numbers, account numbers or passwords—were exposed.
The short version
- Compromised environment: SitusAMC said an unauthorized party accessed information in its systems after it detected an incident on November 12, 2025.
- Named institutions: Reuters, citing reporting by The New York Times, said JPMorgan Chase, Citi and Morgan Stanley were among financial institutions notified that client data may have been accessed. Early reports also referred broadly to other financial institutions and mortgage lenders.
- Potential information: SitusAMC identified corporate records, legal agreements and files connected with residential collateral and asset-management work. Some files may have contained consumer personally identifiable information or sensitive confidential information.
- Banking operations: The FBI, according to the Reuters report, found no operational impact to banking services. SitusAMC said its own services remained operational and that the incident did not involve encrypting malware.
- Current status: SitusAMC said its data review was complete and all required consumer notifications had been made by March 17, 2026.
That status matters. The original November 2025 story was about institutions assessing possible exposure. The current issue is what the completed review established for particular clients and customers—and what remains undisclosed publicly.
What happened at SitusAMC?
SitusAMC provides technology and services used in real-estate finance, mortgage, collateral and asset-management workflows. It detected a security incident on November 12, 2025. In a November 22 statement, the company said corporate information connected with some clients, including accounting records and legal agreements, had been compromised. It also said certain data relating to clients’ customers may have been affected.
The distinction is important: the confirmed compromised environment was SitusAMC’s. Public reporting did not establish that attackers broke into JPMorgan Chase’s, Citi’s or Morgan Stanley’s own core banking systems. The incident illustrates third-party or supply-chain risk: a company can face exposure when a service provider stores or processes records connected with its customers, even if the company’s primary systems remain available.

Which banks were connected to the incident?
Reuters, citing The New York Times, reported that JPMorgan Chase, Citigroup/Citi and Morgan Stanley were among financial institutions notified that client data may have been accessed. The early reports did not establish that all three institutions had identical files, exposure levels or affected customer populations.
Morgan Stanley separately referred to the company in its 2026 proxy statement as among financial institutions affected by a cyberattack on SitusAMC, while describing the issue as potential client-data exposure. That reference confirms the incident was relevant to Morgan Stanley, but it does not establish that every Morgan Stanley customer was affected or specify the exposed data elements.

What each bank has publicly confirmed
- JPMorgan Chase: Reuters reported that JPMorgan was among institutions notified about possible exposure. The cited reporting did not include substantive public details from the bank about affected customers or data categories.
- Citi: Reuters likewise reported Citi among the institutions notified. The cited reporting did not provide a public, bank-specific account of the number of affected customers or the information involved.
- Morgan Stanley: Morgan Stanley’s 2026 proxy statement referred to the SitusAMC cyberattack and potential client-data exposure. The document does not establish that the bank’s own core systems were breached or that all customers experienced the same exposure.
A lack of a detailed public statement should not be treated as either a denial or proof that a customer was affected. Individual notices may come from the relevant bank, mortgage lender, servicer or another SitusAMC client rather than from the bank named in news coverage.

What information may have been exposed?
| Status | Information | What can safely be said |
|---|---|---|
| Identified by SitusAMC | Corporate accounting records, including invoices; legal agreements and other legal records | SitusAMC said certain client-related corporate information was compromised. |
| Potentially involved | Files connected with residential Collateral and Asset Management and loan-file due diligence | These business files could relate to mortgage and real-estate finance activities, but exposure varied by client and file set. |
| Potentially involved | Consumer PII or sensitive confidential information | SitusAMC said customer-related information may have been affected and later notified organizations when such information attributable to them was identified. |
| Not publicly confirmed in the available record | Social Security numbers, driver’s-license numbers, bank-account numbers, passwords, credit histories or complete mortgage files | Do not assume any particular data element was exposed unless it is listed in an individual notification or official client communication. |
A client name appearing in an affected file path did not necessarily mean that every document associated with that client contained consumer PII. SitusAMC said it needed a deeper review to correlate particular documents with particular organizations and information.
Was customer information definitely stolen?
The answer depends on the customer and the records involved. SitusAMC said certain information was compromised, while some customer-related data may have been impacted. Its sample client letter used more specific language for certain clients, stating that information related to them had been acquired by an unauthorized third party.

Those statements do not support a claim that every JPMorgan, Citi or Morgan Stanley customer had data stolen. The nature and extent of exposure varied by client and file set, and the public disclosures do not give an institution-by-institution count of affected consumers.
Were bank accounts or services disrupted?
No operational disruption to banking services was identified in the FBI statement cited by Reuters. SitusAMC also said its services remained operational. That addresses availability, not necessarily confidentiality.

SitusAMC’s response and investigation
According to its public breach updates, SitusAMC said it:
- Started an investigation with outside experts.
- Notified and cooperated with federal law enforcement.
- Took steps to contain the incident.
- Performed forensic analysis and a file-by-file data review.
- Used keyword searches to identify client names in affected file paths.
- Communicated with affected clients.
- Made data-reporting files available through an IDX portal where relevant.
- Implemented additional hardening measures, including credential resets, disabling remote-access tools, firewall-rule updates and enhanced security settings.
On December 9, 2025, SitusAMC said it had not identified evidence of access to or attempted access of the emBTRUST or ProMerit applications for certain warehouse-finance and custody clients. That statement was limited to those applications and client contexts; it should not be read as a finding that no other information was accessed.

What potentially affected customers should do
- Check official communications. Look for a notice from your bank, mortgage lender, servicer or another organization you recognize. Use a known website or the phone number on an existing statement—not a link or number in an unexpected email—to verify it.
- Read the notice for the actual data categories. Keep the letter or secure message. The individual notice is more useful than general coverage for determining whether identity information, financial records or other confidential information was involved.
- Review financial accounts. Check bank, brokerage and credit-card statements for unfamiliar transactions and report suspicious activity through the institution’s established channel.
- Change reused passwords. Prioritize financial accounts and email accounts, and do not reuse the new password elsewhere.
- Turn on multifactor authentication. Use it for email, banking, brokerage, credit-card and other important accounts wherever available.
- Consider a credit freeze when appropriate. If your notice indicates that identity information was exposed, a freeze with Equifax, Experian and TransUnion can help block many new-credit applications. It is generally more protective against new-account fraud than credit monitoring alone, but it is not mandatory and does not prevent every form of fraud.
- Use the official identity-theft process if needed. The Federal Trade Commission’s IdentityTheft.gov service provides steps for reporting and recovering from suspected identity theft.
- Follow the notice’s specific offer. It may explain credit monitoring, identity-restoration services, fraud alerts, reimbursement procedures or a dedicated help line.
Do not provide passwords, one-time security codes or full account credentials to someone who contacts you unexpectedly about the breach. Criminals often exploit public incident news with convincing impersonation messages.
What remains unknown
- The aggregate number of affected individuals.
- The number of JPMorgan Chase, Citi and Morgan Stanley customers affected individually.
- Whether any exposed information was publicly released or used fraudulently.
- The precise data categories involved for each institution or person.
- Whether regulators or courts will impose additional consequences.
- The exact division of notification and remediation responsibility between SitusAMC and each client.
Completion of SitusAMC’s review and required notifications means the company says its review phase is finished. It does not make future misuse impossible, and it does not substitute for the specific notice an affected organization may send.
Why the incident matters beyond these banks
The episode shows why cybersecurity risk in financial services extends beyond a bank’s login page and payment systems. Mortgage and real-estate finance workflows can involve vendors that handle legal agreements, accounting records, loan-file due diligence and collateral or asset-management information. A service provider can therefore become a meaningful confidentiality risk even when the financial institution remains operational.
For customers, the practical lesson is to identify the organization that actually sends a breach notice and to rely on the listed data categories rather than the headline. For financial institutions, the incident highlights the importance of vendor inventories, access controls, remote-access restrictions, logging, incident-notification contracts, file-retention limits and the ability to determine quickly which client records were present in a compromised environment.
