What’s Happening?

As artificial intelligence (AI) continues to evolve, cybercriminals are leveraging AI to launch more sophisticated and automated attacks. In 2025, AI will be used to find vulnerabilities in systems, craft highly personalized phishing emails, and even bypass traditional cybersecurity measures.

Why Houston is at Risk

Houston’s business environment is diverse, ranging from small startups to multinational corporations, all of which rely on technology for operations. The city’s businesses are likely to be targeted by AI-powered attacks that exploit software vulnerabilities or employee naivety. Industries that utilize AI themselves, like the oil and gas sector, may be particularly vulnerable as attackers use AI to bypass security in AI-powered systems.

How to Protect Your Business

Businesses should invest in AI-based cybersecurity tools that can counteract AI-driven attacks. Some recommendations include:

  • AI-Enhanced Security Solutions: Use AI for threat detection and automated response to mitigate risks.
  • Behavioral Analytics: Implement systems that monitor user behavior for abnormal activities, potentially identifying threats that traditional methods may miss.
  • Patch Management: Regularly update software and systems to patch vulnerabilities that AI-powered attacks could exploit.

Cloud Security Gaps

What’s Happening?

The shift toward cloud computing has been beneficial for businesses, but it has also opened up new vulnerabilities. Misconfigured cloud systems, lack of proper security controls, and weak access management are all contributing factors to potential data breaches. In 2025, businesses that rely heavily on cloud infrastructure must take extra precautions to ensure their cloud environments are secure.

Why Houston is at Risk

Houston is home to many businesses that have adopted cloud services for scalability, including energy companies, healthcare providers, and financial institutions. These organizations store sensitive data in the cloud, and any security misstep could lead to catastrophic breaches.

How to Protect Your Business

To safeguard cloud environments, Houston businesses should adopt comprehensive cloud security practices, including:

  • Identity and Access Management (IAM): Ensure that only authorized users have access to critical systems and data.
  • Zero-Trust Security: Implement a zero-trust security framework that assumes all users, inside or outside the network, are potential threats.
  • Cloud Monitoring and Logging: Use cloud-native security tools to monitor for suspicious activities and create detailed logs for incident analysis.

Phishing and Social Engineering Attacks

What’s Happening?

Phishing and social engineering attacks are not new, but they are evolving. In 2025, expect to see more sophisticated phishing schemes using deepfake technology, AI-generated content, and multi-vector approaches that target multiple employees at once. Attackers are becoming experts at impersonating trusted individuals, making it harder for employees to discern between legitimate and fraudulent communications.

Why Houston is at Risk

Houston’s diverse industries and large corporate landscape make it an attractive target for phishing attacks. Criminals may exploit industry-specific themes, such as fake energy contracts or health compliance updates, to trick employees into sharing credentials or downloading malicious attachments.

How to Protect Your Business

Employee awareness is key to combating phishing and social engineering attacks. Some steps include:

  • Regular Phishing Simulations: Conduct regular tests to evaluate how well employees can spot phishing attempts.
  • Multi-Factor Authentication (MFA): Require MFA to add an extra layer of security, even if credentials are compromised.
  • Incident Response Plan: Have a plan in place for quickly responding to phishing attacks and educating employees on reporting suspicious emails.

Supply Chain Attacks

What’s Happening?

Supply chain attacks occur when cybercriminals target a business through one of its third-party suppliers or vendors. In 2025, these types of attacks are expected to increase as businesses become more reliant on third-party service providers. Attackers may infiltrate less secure vendors to gain access to larger, more lucrative targets.

Why Houston is at Risk

Many of Houston’s key industries, including energy and healthcare, depend on extensive networks of third-party suppliers. A breach in one part of the supply chain can cause cascading effects across multiple organizations, making supply chain security a critical issue for local businesses.

How to Protect Your Business

Businesses should ensure that their supply chains are secure by:

  • Vendor Risk Management: Perform thorough security assessments of all vendors and partners before entering into contracts.
  • Continuous Monitoring: Implement continuous monitoring tools to track vendor activity and detect any suspicious behavior.
  • Contractual Security Requirements: Include cybersecurity requirements in contracts with third-party providers to ensure they maintain high security standards.
