Susan Fischgrund Listed by apt73 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People who have worked with or received services from language therapist Susan Fischgrund may now face uncertainty about whether their personal details or related documents have been taken by criminals. Public records show that the practice was listed by a ransomware group that claims to have removed internal files, raising the practical risk that private information could be misused for fraud, identity theft or unwanted contact.

The listing itself does not confirm every detail of the intrusion, and the number of individuals affected remains unknown. Still, any exposure of personal information and documents from a clinical or therapeutic setting carries lasting consequences for those whose data may be involved.

What happened

On 21 October 2024, Susan Fischgrund was publicly listed by the ransomware group known as apt73. According to the report, the group claims to have carried out a ransomware attack that included the exfiltration of internal files. The volume of data described is 2 GB, consisting of personal information and documents. No further technical details about the method of intrusion, the precise date of the attack, or the total number of people affected have been disclosed in the available record. The listing on the group’s leak site remains an unverified claim by the actors themselves.

The group behind it: apt73

apt73 is a ransomware operation that follows the now-common double-extortion model used by many such groups. Actors associated with the name typically gain access to a target network, move laterally to locate valuable data, copy selected files, and then encrypt systems while threatening to publish the stolen material if a ransom is not paid. Victims are often named on dedicated leak sites as a form of pressure. Public reporting on apt73 and similar groups shows they have previously targeted a range of organisations across professional services and smaller enterprises, relying on phishing, exploited vulnerabilities or stolen credentials to enter networks. In this instance the group claims Susan Fischgrund as a victim and asserts that internal files were removed; those assertions have not been independently confirmed beyond the listing itself.

Who is Susan Fischgrund?

Susan Fischgrund operates as a language therapist. Practitioners in this field work with individuals who have speech, language or communication difficulties, often including children, adults recovering from injury, or people with developmental conditions. Such practices routinely hold client intake forms, session notes, contact details, medical or educational histories, and billing records. Because the work involves sensitive personal and sometimes health-related information, any unauthorised access can affect both the professional reputation of the practice and the privacy of the people who have sought help there. A breach of this kind is consequential precisely because the data held is inherently personal and often shared under an expectation of confidentiality.

What data was at risk

The available facts state that internal files were exfiltrated and that the material comprises personal information and documents totalling 2 GB. No more granular inventory of the files has been published. Organisations of this type typically store names, addresses, telephone numbers, email addresses, dates of birth, insurance or payment details, clinical notes and correspondence. Whether any of those specific categories were present in the 2 GB set remains unconfirmed. The exact contents of the stolen data are therefore not publicly verified beyond the broad description of personal information and documents.

Why it matters

For individuals whose records may have been taken, the primary risks are identity fraud, phishing attempts that use accurate personal details, and the possible disclosure of private health or educational information. Even a modest volume of data can be enough for criminals to craft convincing social-engineering attacks or to sell records on underground markets. For the practice itself, the incident can erode client trust, trigger regulatory notification duties, and create ongoing operational disruption while systems are restored and clients are informed. Because the number of people affected is unknown, the full scale of potential harm cannot yet be measured, which itself prolongs uncertainty for anyone who has interacted with the service.

What to do if you're exposed

If you have been a client or contact of Susan Fischgrund, treat the possibility of exposure seriously even though confirmation is limited. Practical first steps include:

• Monitor bank, credit-card and credit-report activity for unexpected accounts or inquiries.
• Change passwords on any accounts that may have shared credentials or personal details with the practice, and enable multi-factor authentication where available.
• Be alert to phishing emails or calls that reference language-therapy services or personal information you may have provided.
• Consider placing a fraud alert with major credit bureaus if you notice any suspicious activity.
• Run a free exposure scan of your email address to check whether that address has already appeared in known breach data sets.

These measures do not reverse the incident, but they reduce the chance that stolen information can be used against you in the weeks and months ahead.
