On June 23, 2025, the New York State Department of Financial Services (“NY DFS”) issued guidance to NY DFS-regulated individuals and entities regarding the impact of “ongoing global conflicts” to the financial sector. The guidance follows a bulletin from the U.S. Department of Homeland Security about the “heightened threat environment” in the United States, which specifically references cyber attacks. The NY DFS guidance highlights three key areas of focus: cybersecurity, sanctions, and virtual currency, and may be helpful for organizations across industries globally:Continue Reading New York State Department of Financial Services Issues Guidance on Cybersecurity, Sanctions, and Virtual Currency Following Escalation of Iran Conflict

On June 6, 2025, President Trump issued an Executive Order (“Sustaining Select Efforts to Strengthen the Nation’s Cybersecurity and Amending Executive Order 13694 and Executive Order 14144”) (the “Order”) that modifies certain initiatives in prior Executive Orders issued by Presidents Obama and Biden and highlights key cybersecurity priorities for the current Administration.  Specifically, the Order (i) directs that existing federal government regulations and policy be revised to focus on securing third-party software supply chains, quantum cryptography, artificial intelligence, and Internet of Things (“IoT”) devices and (ii) more expressly focuses cybersecurity-related sanctions authorities on “foreign” persons.  Although the Order makes certain changes to prior cybersecurity related Executive Orders issued under previous administrations, it generally leaves the framework of those Executive Orders in place.  Further, it does not appear to modify other cybersecurity Executive Orders.[1]  To that end, although the Order highlights some areas where the Trump administration has taken a different approach than prior administrations, it also signals a more general alignment between administrations on core cybersecurity principles.Continue Reading White House Issues New Cybersecurity Executive Order

On May 22, 2025, the Cybersecurity and Infrastructure Security Agency (“CISA”), which sits within the Department of Homeland Security (“DHS”) released guidance for AI system operators regarding managing data security risks.  The associated press release explains that the guidance provides “best practices for system operators to mitigate cyber risks through the artificial intelligence lifecycle, including consideration on securing the data supply chain and protecting data against unauthorized modification by threat actors.”  CISA published the guidance in conjunction with the National Security Agency, the Federal Bureau of Investigation, and cyber agencies from Australia, the United Kingdom, and New Zealand.  This guidance is intended for organizations using AI systems in their operations, including Defense Industrial Bases, National Security Systems owners, federal agencies, and Critical Infrastructure owners and operators. This guidance builds on the Joint Guidance on Deploying AI Systems Security released by CISA and several other U.S. and foreign agencies in April 2024.Continue Reading CISA Releases AI Data Security Guidance

Earlier in April, the U.S. National Institute of Standards and Technology (“NIST”) published Special Publication (“SP”) 800-61, Incident Response Recommendations and Considerations for Cybersecurity Risk Management, Revision 3 (“NIST SP 800-61”).  NIST SP 800-61 Revision 3 (“Revision 3”) is a significant change, as it not only represents the first update of the document since 2012, but also now maps the document’s recommendations and considerations for incident response to the six functions outlined in the recently-updated NIST Cybersecurity Framework 2.0—Govern, Identify, Protect, Detect, Respond, and Recover.  As a result, Revision 3 includes significant new recommendations and guidance for incident response, and entities should consider reviewing and updating their incident response plans and procedures to incorporate these recommendations, particularly if an entity has aligned its cybersecurity program with the NIST Cybersecurity Framework or used the prior versions of NIST SP 800-61 as a basis for existing incident response plans or procedures.Continue Reading NIST Publishes Updated Incident Response Recommendations and Considerations

On 15 January 2025, the European Commission published an action plan on the cybersecurity of hospitals and healthcare providers (the “Action Plan”). The Action Plan sets out a series of EU-level actions that are intended to better protect the healthcare sector from cyber threats. The publication of the Action Plan follows a number of high-profile incidents in recent years where healthcare providers across the European Union have been the target of cyber attacks.Continue Reading European Commission Publishes Action Plan on Cybersecurity of Hospitals and Healthcare Providers

On December 24, 2024, New York Governor Kathy Hochul signed into law an amendment to New York General Business Law § 899-aa modifying the state’s data breach notification requirements.  The amended law, which is effective immediately, imposes new requirements businesses must follow when providing notifications following a data breach affecting New York residents.  Specifically, businesses now must disclose data breaches affecting New York residents within thirty days from the discovery of a breach.  Additionally, the amendment adds the New York Department of Financial Services (“NYDFS”) to the list of state regulators that must be notified whenever a breach requiring notification to New York residents occurs. Continue Reading New York Adopts Amendment to the State Data Breach Notification Law

In the final quarter of 2024, there have been significant developments in the EU cybersecurity legal landscape. Most prominently, the EU institutions adopted the Cyber Resilience Act and mid-October marked the deadline for Member States to transpose the NIS2 Directive into national law. Most Member States failed to meet the NIS2 transposition deadline, which resulted in the European Commission sending a formal notice to 23 Member States, urging them to transpose the Directive. These 23 Member States have been given two months to respond. (For more information on the Cyber Resilience Act and NIS2 Directive, see our blog posts here and here.)Continue Reading Three Recent Developments in the EU Cyber Landscape

On October 16, 2024, the New York Department of Financial Services (“NYDFS”) issued an industry letter (the “Guidance”) highlighting the cybersecurity risks arising from the use of artificial intelligence (“AI”) and providing strategies to address these risks.  While the Guidance “does not impose any new requirements,” it clarifies how Covered Entities should address AI-related risks as part of NYDFS’s landmark cybersecurity regulation, codified at 23 NYCRR Part 500 (“Cybersecurity Regulation”).  The Cybersecurity Regulation, as revised in November 2023, requires Covered Entities to implement certain detailed cybersecurity controls, including governance and board oversight requirements.  Covered Entities subject to the Cybersecurity Regulation should pay close attention to the new Guidance not only if they are using or planning on using AI, but also if they could be subject to any of the AI-related risks or attacks described below. Continue Reading NYDFS Issues Industry Guidance on Risks Arising from Artificial Intelligence

On September 17, 2024, the U.S. Cybersecurity and Infrastructure Security Agency (“CISA”) and the Federal Bureau of Investigation (“FBI”) published a Secure by Design Alert, cautioning senior executives and business leaders to be aware of and work to eliminate cross-site scripting (“XSS”) vulnerabilities in their products (the “Alert”).  XSS vulnerabilities allow “threat actors to inject malicious scripts into web applications, exploiting them to manipulate, steal, or misuse data across different contexts.” Continue Reading CISA and FBI Publish a Secure by Design Alert to Eliminate Cross-Site Scripting Vulnerabilities

This quarterly update highlights key legislative, regulatory, and litigation developments in the second quarter of 2024 related to artificial intelligence (“AI”), connected and automated vehicles (“CAVs”), and data privacy and cybersecurity. Continue Reading U.S. Tech Legislative, Regulatory & Litigation Update – Second Quarter 2024
