The week closes with an uptick in cyberattacks affecting critical sectors, from energy and public services to airport infrastructure, and the debut of AI-powered ransomware. Discover the most relevant details and protection keys.
ESET and other researchers have presented the analysis of PromptLock, the first proven ransomware that uses generative artificial intelligence to autonomously select, encrypt and steal information. This threat multiplies the possibilities of cybercrime: malware is adjusted in real time thanks to natural language processing, circumventing classic detection systems. The development of PromptLock marks the beginning of a new era where a prompt is enough to launch sophisticated attacks, reducing costs and making this type of tool available to more malicious actors. The community warns that generative ransomware will be a trend in the coming months, requiring defenses to be reinforced with equally intelligent techniques and solutions.
On September 12, Madrileña Red de Gas confirmed a security breach that exposed identification and contact data, including the CUPS, the reference number for each gas meter. Although the company assures that passwords and bank details have not been affected, the risks of phishing and impersonation attempts increase after this incident. In response, double authentication has been implemented for the Virtual Office and customers are advised to exercise extreme caution in the face of suspicious emails. The incident reflects the importance of cybersecurity in the energy sector and the urgency of collaboration with INCIBE and the AEPD to limit damage and restore trust.
The automated irrigation system of the Jardín del Turia was left out of control due to a computer attack of Russian origin, affecting section VI of the largest urban park in Spain. The incident forced the system to operate manually and put municipal technicians on alert. Although no personal data was compromised, the vulnerability of municipal infrastructures to cyberthreats was evident. Valencia has intensified audits and collaborates with security experts to shield critical systems in the face of the growing wave of attacks on public administrations in Spain.
A cyberattack against the company Collins Aerospace caused the collapse of automatic check-in and boarding systems at several key airports, forcing them to manage processes manually, canceling flights and generating endless queues. Brussels was the most affected, with up to 50% of flights suspended and more than 35,000 passengers injured. The attack, of origin and technique yet to be clarified, shows the enormous economic and logistical impact that this type of incident can have on European mobility.
According to various studies, Spain has exceeded 2,000 weekly cyberattacks, especially in public administration and telecommunications. Ransomware and phishing remain the main vectors, while the use of AI by criminal groups increases the sophistication of threats. The country is on high alert: companies and entities must reinforce training, monitoring and rapid response policies to mitigate damage and protect essential services.
