Sensitive Data Exposed: Your PII and PHI Are at Risk
The Altos Inc. data breach exposed a combination of Personally Identifiable Information (PII) and Protected Health Information (PHI). This sensitive combination is highly valuable to cybercriminals and can be used for various forms of fraud.
The information potentially compromised includes:
- Name, Address, and Date of Birth
- Social Security number (SSN)
- Health Information (e.g., medical records, billing data)
- Health Insurance Information
The theft of this data can have severe and long-lasting consequences for victims, putting them at risk of both medical and financial identity theft.
Altos Inc.’s Services and the Businesses They Serve
As a medical billing and transcription provider in Southern California, Altos Inc. serves a wide range of healthcare clients, from large hospitals to small private medical practices and organizations. The company’s services directly handle some of the most sensitive patient data, including:
- Medical Billing and Revenue Cycle Management
- Coding
- Credentialing and Provider Enrollment
- Verification of Benefits
- Workers’ Compensation Collection
- Personal Injury Collection
- Medical Transcription
- Medical/Legal Record Review
Altos Inc. has long promoted its “stellar reputation” and its commitment to ensuring client data is “Securely and Accurately Represented.” The company touts strict security protocols, round-the-clock surveillance, and up-to-date firewalls. This breach, however, starkly contrasts those promises, showing that vulnerabilities can exist even with companies that claim to prioritize data security.
According to a notice filed by Alios, Inc. with the CA Attorney General’s Office, the data breach directly compromised an internal system related to these services, meaning that individuals who were patients of a healthcare provider that used any of these services may have had their personal and health information exposed.
Details of the Altos Inc. Data Breach: A Timeline of Exposure
Altos, Inc., based in Irvine, California, discovered on June 17, 2025, that one of its internal systems was exposed to the Internet. An investigation was immediately launched with the help of a cybersecurity firm. The firm later determined that an unauthorized party had gained access to the system between May 30 and May 31, 2025.
After a comprehensive review, Altos concluded on July 21, 2025, that sensitive personal and health information had been compromised. The company has secured the system and is offering affected individuals credit monitoring and identity theft protection services through Epiq Privacy Solutions ID. However, the total number of individuals affected has not been disclosed, and the breach could be larger than initially perceived due to the breadth of services Altos provides to its healthcare clients.

Potential Impact on Victims of the Altos Inc. Data Breach
The compromise of your sensitive PII and PHI in the Altos Inc. data breach places you at significant and ongoing risk of:
- Medical Identity Theft: Stolen PHI could be used to obtain fraudulent medical services, prescriptions, or equipment, leading to inaccurate medical records and financial burdens.
- Financial Identity Theft: Compromised SSNs can be used to open fraudulent credit accounts, file false tax returns, and commit other forms of financial fraud.
- Targeted Phishing and Social Engineering Attacks: The stolen data could be used by cybercriminals to craft highly personalized and convincing scams to extract even more sensitive information from you.

Legal Claims in the Altos Inc. Data Breach Lawsuit Investigation
Woods Lonergan PLLC’s Data Breach attorneys are focused on potential violations of law and legal claims in the Altos Inc. data breach case, including:
- Negligence: Altos Inc. is a business that specifically touts its security protocols and professionalism. The company’s failure to adequately protect sensitive data from being exposed to the Internet, as well as the month-long investigation period, suggests a lapse in reasonable cybersecurity measures and oversight.
- HIPAA Violations: As a business process outsourcing company that handles patient data, Altos Inc. has a clear obligation under the Health Insurance Portability and Accountability Act (HIPAA) to safeguard Protected Health Information (PHI). The data breach and exposure of PHI may constitute a direct violation of this federal law.
- Breach of Contract: The breach may constitute a breach of implied or express contracts with its healthcare clients to protect patient information, which was provided to Altos in the normal course of business.
- Other Potential Claims: Depending on the specific circumstances and applicable state laws, additional claims may be possible as our investigation uncovers more details.
What Individuals Affected by the Altos Inc. Data Breach Should Do Now
If you are a patient of a healthcare provider in Southern California that uses Altos Inc., taking immediate and proactive steps is crucial:
- Review All Communications: Carefully read any communication from Altos Inc. or your healthcare provider to understand which specific types of your personal information were exposed. You can view the official consumer notice from the company here: Altos Inc. Consumer Notice
- Monitor Financial and Medical Accounts: Closely scrutinize all financial statements, credit card activity, and your credit reports for any unauthorized or suspicious transactions. Also, review your medical records and insurance statements for any fraudulent claims.
- Consider a Fraud Alert or Credit Freeze: Placing a fraud alert makes it harder for identity thieves to open new accounts in your name. A credit freeze offers stronger protection by restricting access to your credit report altogether.
- Change Passwords: Immediately update passwords for all online accounts, especially those linked to your healthcare provider’s portal, or other accounts that share similar credentials.
- Be Vigilant Against Phishing: Be highly suspicious of unsolicited emails, texts, or calls, particularly those claiming to be from Altos Inc. or your healthcare provider. Cybercriminals will use stolen data to craft highly targeted scams.
- Consult Legal Professionals: To understand your full rights and potential legal recourse, contact experienced data breach attorneys. Joining an Altos Inc. data breach class action lawsuit can be an effective way to seek compensation for damages, including financial losses, privacy violations, and emotional distress.

Frequently Asked Questions (FAQs) About Data Breaches
What is a data breach?
A data breach occurs when unauthorized individuals gain access to sensitive or confidential data, often leading to the exposure, theft, or loss of personal, financial, or proprietary information. This could involve hacking, accidental sharing, or physical theft of data storage devices.
What kind of data can be compromised in a data breach?
Data that can be compromised includes Personal Identifiable Information (PII) such as names, addresses, Social Security numbers, birthdates, phone numbers; Financial Information like credit card numbers or bank account details; Medical Records including health history and insurance details; Login Credentials; and even Business Data like proprietary information or intellectual property.
How do data breaches happen?
Data breaches can occur through various methods, including hacking (cybercriminals exploiting vulnerabilities), phishing (fraudulent emails tricking users), malware (malicious software infecting systems), and insider threats (employees or contractors intentionally or accidentally exposing data).
What should I do if I believe my data has been breached?
Immediately change passwords for any affected accounts, monitor bank accounts and credit cards for unusual activity, notify affected organizations, report to authorities in cases of identity theft, consider placing fraud alerts or credit freezes, and stay alert for phishing scams.
How can I protect myself from data breaches?
To reduce risk, use strong and unique passwords, enable multi-factor authentication, be cautious of phishing scams, update software regularly, encrypt sensitive data, use secure networks, and regularly review privacy settings on online accounts.
What is the difference between a data breach and a data leak?
