## Article

An oil tanker carrying approximately 2.3 million barrels of crude oil faced a significant cybersecurity incident while on its way to Texas. The vessel, identified as the VL Prosperity and flagged under Liberia, was targeted by hackers during its journey from Egypt's Sidi Kerir oil terminal to Galveston, Texas. The cyber attack reportedly took place as the tanker navigated through the Strait of Gibraltar, compromising its fuel systems, engine speed, and communications for a duration of 30 hours.

In response, a specialized team from the FBI and the US Coast Guard boarded the tanker two weeks later. They conducted a detailed investigation and provided assistance to the crew in removing the threat from both the Information Technology (IT) and Operational Technology (OT) systems on board. Despite the severity of the incident, the US Coast Guard confirmed that there were no disruptions to the tanker's operations, nor were there any injuries or environmental impacts reported.

While the specific perpetrators of the attack remain unidentified, cybersecurity experts emphasize the ease with which ship systems can be compromised. Operational technology specialist Rob Lee highlighted the vulnerability of large vessels like supertankers, which often operate with a shared network behind a single firewall. Once breached, hackers can manipulate crucial systems such as navigation and propulsion.

Rear Admiral Amy Grable of the US Coast Guard Cyber Command underscored the need for robust cybersecurity measures, stating that even unsophisticated attacks can be effective. The rapid advancement of artificial intelligence necessitates swift action to protect critical infrastructure. While the likelihood of a hacker remotely commandeering a supertanker is low, the potential for significant disruption remains a serious concern.

Given the high stakes involved with vast sums of money flowing through US ports, the call for enhanced cybersecurity practices is urgent. Rear Admiral Grable advises implementing network segmentation, increasing awareness of phishing threats, and maintaining basic cyber hygiene to mitigate risks. These precautions are essential not only for maritime security but for safeguarding digital environments across all sectors.
