CISA has issued a warning that unsophisticated hackers are targeting critical oil infrastructure in the U.S., posing a significant threat to the sector's cybersecurity. The agency recommends a range of measures to mitigate this risk, including removing public-facing OT devices from the internet and securing remote access using virtual private networks (VPNs) with phishing-resistant multifactor authentication (MFA). By taking these steps, critical infrastructure organizations can significantly reduce the risk of a successful attack and ensure the continued reliability of essential services.

CISA, or the Cybersecurity and Infrastructure Security Agency, has issued a warning to critical infrastructure organizations regarding the growing threat of unsophisticated hackers targeting the U.S. oil and natural gas sectors. The agency's alert, which was released in May 2025, highlights the increasing concern over the vulnerability of industrial control systems (ICS) and operational technology (OT) equipment to basic cyber attacks.
According to CISA, these attacks, often carried out by unsophisticated threat actors, can still have significant consequences, including physical damage and disruptions to operations. The agency notes that despite the relatively simple nature of these tactics, the presence of poor cyber hygiene and exposed assets can escalate the threats, leading to more severe outcomes such as defacement, configuration changes, operational disruptions, and even physical damage.
The joint advisory issued by CISA, along with the FBI, Environmental Protection Agency (EPA), and the Department of Energy (DOE), provides detailed guidance for network defenders seeking to reduce the risk of potential breaches. The key recommendations include ensuring that an organization's attack surface is as small as possible by removing public-facing OT devices from the internet, due to their vulnerability to exploitation. Additionally, security teams are advised to change default passwords to unique and strong ones, secure remote access to OT assets using a virtual private network (VPN) with phishing-resistant multifactor authentication (MFA).
Segmenting IT and OT networks is also recommended, utilizing demilitarized zones to separate local area networks from untrusted networks. Furthermore, the agencies emphasize the importance of regularly testing business continuity and disaster recovery plans, fail-safe mechanisms, islanding capabilities, software backups, and standby systems to ensure safe manual operations in the event of an incident.
The advisory comes after CISA and the EPA warned water facilities to secure their Internet-exposed Human Machine Interfaces (HMIs) from cyberattacks in December. Three months earlier, the U.S. cybersecurity agency also stated that threat actors were trying to breach critical infrastructure networks, including water and wastewater systems, by targeting Internet-exposed industrial devices using default credentials and "unsophisticated" methods such as brute force attacks.
The alarming trend highlighted by CISA underscores the need for increased vigilance among critical infrastructure organizations to safeguard their systems against even the most basic of threats. By implementing the recommended measures and staying informed about emerging vulnerabilities, these organizations can significantly reduce the risk of a successful attack and minimize potential disruptions to essential services.
In light of this warning, it is essential for critical infrastructure organizations to take proactive steps to enhance their cybersecurity posture. This includes conducting regular vulnerability assessments, implementing robust access controls, and maintaining up-to-date security patches for all systems. By prioritizing cyber resilience and adopting best practices for OT security, these organizations can significantly mitigate the risks posed by unsophisticated hackers and ensure the continued reliability of critical infrastructure.
Furthermore, the warning issued by CISA serves as a reminder of the importance of collaboration and information-sharing among stakeholders in the cybersecurity community. As the threat landscape continues to evolve, it is crucial that organizations share intelligence and best practices to stay ahead of emerging threats and develop effective countermeasures.
In conclusion, the alert from CISA highlights the urgent need for critical infrastructure organizations to prioritize OT security and take proactive steps to enhance their defenses against unsophisticated hackers. By implementing recommended measures and staying informed about emerging vulnerabilities, these organizations can significantly reduce the risk of a successful attack and ensure the continued reliability of essential services.
