In today’s rapidly evolving digital landscape, businesses in New York City face an increasingly sophisticated array of cybersecurity threats. As a hub for finance, media, technology, and countless other industries, NYC businesses are prime targets for cybercriminals looking to extract valuable data or disrupt operations.
At Northern Star IT, we’ve been protecting NYC businesses for over 16 years, and we’ve observed significant shifts in the threat landscape. Here are the five most pressing cybersecurity threats NYC businesses need to be aware of in 2025:
1. Ransomware-as-a-Service (RaaS) Targeting Small and Mid-Size Businesses
Ransomware attacks have evolved from broad, untargeted campaigns to highly specialized operations targeting specific industries prevalent in NYC. The rise of Ransomware-as-a-Service has lowered the barrier to entry for cybercriminals, allowing less technically skilled actors to deploy sophisticated attacks against vulnerable businesses.
What we’re seeing in NYC: Financial services, healthcare providers, and legal firms are experiencing targeted ransomware attacks with demands specifically calibrated to their revenue models. Small and mid-size businesses are increasingly targeted as they often lack the robust security infrastructure of larger enterprises.
Protection strategy: Implement a comprehensive backup solution with immutable storage, conduct regular security awareness training, and develop an incident response plan specific to ransomware scenarios.
2. Supply Chain Vulnerabilities
NYC’s complex business ecosystem means many companies rely on dozens or even hundreds of vendors and service providers. This interconnected network creates numerous potential entry points for attackers.
What we’re seeing in NYC: Sophisticated threat actors are targeting smaller vendors and service providers as a pathway to compromise their larger NYC-based clients. Many attacks begin with a compromise of a trusted third-party software provider or managed service provider.
Protection strategy: Implement a vendor risk management program, conduct security assessments of critical suppliers, and establish clear security requirements in vendor contracts.
3. AI-Powered Social Engineering
The newest generation of AI tools has dramatically enhanced social engineering capabilities, making phishing and business email compromise (BEC) attacks more convincing than ever.
What we’re seeing in NYC: Executives at financial services and media companies are being targeted with highly personalized spear-phishing attempts. AI-generated voice cloning is being used to impersonate C-suite executives for fraudulent fund transfers.
Protection strategy: Implement multi-factor authentication across all systems, establish strict verification protocols for financial transactions, and conduct regular phishing simulations with employees.
4. Cloud Configuration Vulnerabilities
As NYC businesses accelerate their digital transformation initiatives, many are migrating to cloud environments without fully understanding the shared responsibility model of security.
What we’re seeing in NYC: Misconfigured cloud storage, excessive permissions, and unsecured APIs are leading to data exposures. Tech startups in particular are experiencing breaches due to development environments with inadequate security controls.
Protection strategy: Implement cloud security posture management (CSPM) tools, establish infrastructure as code (IaC) security scanning, and conduct regular cloud security assessments.
5. IoT Device Exploitation in Smart Buildings
New York’s push toward smart building technology has introduced thousands of connected devices into the corporate environment, many with inadequate security.
What we’re seeing in NYC: Building management systems, surveillance cameras, and environmental controls are being compromised as entry points into corporate networks. Office buildings with multiple tenants face particular challenges with shared IoT infrastructure.
Protection strategy: Segment IoT devices on isolated networks, implement IoT-specific security monitoring, and establish an IoT security policy for all devices connecting to corporate networks.
