On June 30, 2025, the Cybersecurity and Infrastructure Agency (CISA), the Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center (DC3), and the National Security Agency (NSA) warned U.S. critical infrastructure organizations and other companies that the threat of cyber attacks from Iran-affiliated cyber actors is heightened in the wake of the Iran conflict. The agencies cautioned that the risk is particularly high for Defense Industrial Base (DIB) companies with Israeli ties. This warning was issued shortly after the New York Department of Financial Services provided similar guidance to companies in the financial sector, which we discussed here.

In addition to distributed denial of service (DDoS) and ransomware attacks, the agencies explained that malicious actors may target operational technology (OT) connected to the public internet to perpetrate attacks. A variety of mitigation measures for critical infrastructure companies are listed, such as:

  • Identifying and disconnecting OT and industrial control systems (ICS) assets from the public internet;
  • Ensuring devices and accounts are protected with strong, unique passwords (if not using MFA) and replacing weak or default passwords;
  • Implementing phishing-resistant MFA for OT network access;
  • Applying the latest manufacturer patches for internet-facing systems;
  • Prioritizing the monitoring of user access logs for remote access to OT networks and firmware or configuration changes; and
  • Ensuring incident response and business continuity plans are in place, reviewing and rehearsing these plans, and updating them based on the results.

Caleb Skeath helps companies manage their most complex and high‑stakes cybersecurity and data security challenges, combining deep regulatory insight, technical fluency, and practical judgment informed by leading incident response matters.

Caleb Skeath advises in‑house legal and security teams on the full lifecycle of cybersecurity and privacy risk—from governance and preparedness through incident response, regulatory engagement, and follow‑on litigation. A Certified Information Systems Security Professional (CISSP), he is trusted by clients across highly regulated and technology‑driven sectors to provide clear, practical guidance at moments when legal judgment, technical understanding, and business realities must be aligned.

Caleb has deep experience leading and overseeing responses to complex cybersecurity incidents, including ransomware, data theft and extortion, business email compromise, advanced persistent threats and state-sponsored threat actors, insider threats, and inadvertent data loss. He regularly helps in‑house counsel structure and manage investigations under attorney‑client privilege; coordinate with internal IT, information security, and executive stakeholders; and engage with forensic firms, crisis communications providers, insurers, and law enforcement. A central focus of his practice is advising on notification obligations and strategy, including the application of U.S. federal and state data breach notification laws and requirements along with contractual notification obligations, and helping companies make defensible, risk‑informed decisions about timing, scope, and messaging.

In addition to his work responding to cybersecurity incidents, Caleb works closely with clients’ legal, technical, and compliance teams on cybersecurity governance, regulatory compliance, and pre‑incident planning. He has extensive experience drafting and reviewing cybersecurity policies, incident response plans, and vendor contract provisions; supervising cybersecurity assessments under privilege; and advising on training and tabletop exercises designed to prepare organizations for real‑world incidents. His work frequently involves translating evolving regulatory expectations into actionable guidance for in‑house counsel, including in highly-regulated sectors such as the financial sector (including compliance with NYDFS cybersecurity regulations, the Computer Security Incident Notification Rule, and GLBA guidelines and guidance) and the pharmaceutical and healthcare sector (including compliance with GxP standards, FDA medical device guidance, and HIPAA).

Caleb’s practice also addresses evolving and emerging areas of cybersecurity and data security law, including advising clients on compliance with the Department of Justice’s Data Security Program, CISA‑related security requirements for restricted transactions, and preparation for new regulatory regimes such as the CCPA cybersecurity audit requirements and federal incident reporting obligations. He regularly counsels clients on how artificial intelligence and connected devices intersect with cybersecurity, privacy, and consumer protection risk, and how to support innovation while managing regulatory exposure.

Caleb also has extensive experience helping clients navigate high-stakes cybersecurity-related inquiries from the Federal Trade Commission, state Attorneys General, and other sector-specific regulators, including incident-specific inquiries as well as broader inquiries related to an entity’s cybersecurity practices and the security of product or service offerings. For companies that have entered into cybersecurity-related settlement agreements with regulators, Caleb has helped guide them through compliance with settlement agreement obligations, including navigating required third-party assessments and strategically responding to cybersecurity incidents that can arise while a company is subject to a settlement agreement. Caleb also routinely works hand-in-hand with colleagues in Covington’s class action litigation, commercial litigation, and insurance recovery practices to prepare for and successfully navigate incident-related disputes that can devolve into litigation.
