Attorney for Data Breach

Data breaches have become one of the most pressing legal and financial threats facing New York individuals and businesses. From small medical practices in Manhattan to large financial institutions on Wall Street, no organization is immune from cyberattacks, ransomware, phishing schemes, or insider threats. When sensitive personal information is exposed, the legal consequences can be severe — including regulatory penalties, class action lawsuits, and reputational harm. Our New York data breach attorneys provide comprehensive legal counsel to help clients navigate breach response, regulatory compliance, and litigation under New York law.

What Constitutes a Data Breach Under New York Law?

Under New York General Business Law § 899-aa, a data breach is generally defined as the unauthorized acquisition or access of computerized data that compromises the security, confidentiality, or integrity of private information. The Stop Hacks and Improve Electronic Data Security Act (the SHIELD Act), enacted in 2019, significantly expanded the scope of what qualifies as a breach and broadened the definition of "private information" to include:

• Social Security numbers
• Driver's license or non-driver identification numbers
• Financial account numbers, credit card numbers, or debit card numbers (with or without security codes if access could be gained)
• Biometric information such as fingerprints, voice prints, or retina scans
• Username or email address combined with a password or security question and answer

Importantly, the SHIELD Act applies to any business or person that owns or licenses the private information of New York residents — even if the business itself is not located in New York. This expansive jurisdictional reach makes compliance critical for organizations of all sizes.

How Our New York Data Breach Attorneys Can Help

Responding to a data breach requires immediate, coordinated legal action. Mistakes during the early stages of breach response can amplify legal exposure, increase regulatory scrutiny, and undermine defenses in subsequent litigation. Our firm provides end-to-end legal services tailored to each phase of a data security incident.

Incident Response and Breach Investigation

When a suspected breach occurs, time is of the essence. Our attorneys work alongside forensic investigators, IT professionals, and insurance carriers to:

• Preserve attorney-client privilege over the investigation
• Identify the scope and nature of the compromised data
• Determine whether the incident triggers notification obligations
• Coordinate with law enforcement when appropriate
• Implement containment and remediation measures

Notification Obligations Under New York Law

The SHIELD Act and General Business Law § 899-aa require businesses to notify affected New York residents "in the most expedient time possible and without unreasonable delay" following discovery of a breach. Notification must also be provided to:

• The New York State Attorney General
• The New York Department of State
• The New York State Police
• Consumer reporting agencies (when more than 5,000 New York residents are notified at once)

Our attorneys draft compliant notification letters, coordinate communications with regulators, and ensure that timing, content, and method of notice meet statutory requirements. We also advise on the limited "risk of harm" exception that may apply when exposure of information is unlikely to result in misuse.

Regulatory Compliance and Reasonable Safeguards

The SHIELD Act requires businesses handling private information of New York residents to implement reasonable administrative, technical, and physical safeguards. For regulated industries, additional rules apply — including the New York Department of Financial Services (NYDFS) Cybersecurity Regulation (23 NYCRR Part 500), which imposes stringent requirements on banks, insurers, and other financial services companies licensed in New York.

Our attorneys help clients design and implement compliant cybersecurity programs, including:

• Written information security policies (WISPs)
• Risk assessments and vendor management programs
• Employee training and access controls
• Multi-factor authentication and encryption protocols
• Incident response plans and tabletop exercises
• Annual compliance certifications required under NYDFS regulations

Representing Victims of Data Breaches

If your personal information was exposed because a company failed to protect it, you may have legal claims under New York law. Victims of data breaches frequently suffer identity theft, fraudulent charges, tax fraud, medical identity theft, and significant time spent restoring their financial identity. Our attorneys represent individuals and classes of consumers in actions seeking compensation for:

• Out-of-pocket losses from fraud or identity theft
• Costs of credit monitoring and identity restoration services
• Diminished value of personal information
• Emotional distress and time lost addressing the breach
• Statutory damages where available

Common legal theories in New York data breach litigation include negligence, breach of contract, breach of implied contract, breach of fiduciary duty, and violations of New York General Business Law §§ 349 and 350 (deceptive business practices and false advertising). Where a company failed to implement reasonable safeguards as required by the SHIELD Act, that failure can serve as evidence of negligence.

Defending Businesses in Data Breach Litigation

For businesses facing data breach claims, our attorneys provide aggressive defense in state and federal courts throughout New York. We have experience defending putative class actions, multi-district litigation, and individual claims involving:

• Healthcare data breaches and HIPAA-related claims
• Financial services and NYDFS-regulated entities
• Retail and e-commerce platforms
• Educational institutions and student data
• Ransomware events and business email compromise
• Vendor and third-party service provider breaches

We focus on early case assessment, dispositive motion practice on issues such as Article III standing and damages, and strategic resolution where appropriate.

New York Attorney General Investigations

The New York Attorney General's Bureau of Internet and Technology actively investigates data security incidents and has secured significant settlements from companies that failed to protect consumer data. Penalties under the SHIELD Act can reach $20 per failed notification, with maximum penalties of $250,000, plus potential additional penalties under General Business Law § 349. Our attorneys represent companies in Attorney General investigations, responding to subpoenas and information requests, negotiating assurances of discontinuance, and minimizing financial and reputational exposure.
