Blackout d'Espagne: Cyber ou pas? Une analyse technique impartiale Spain\\'s blackout: Cyber or Not? An unbiased technical analysis (lien direct) |
IntroductionYesterday afternoon, I was writing what should have been the regular newsletter when the power suddenly went out. I wasn\'t alarmed at all because I live in a mountain area, and power outages like this happen several times a year. It was a slightly windy day, so I assumed that maybe a tree had cracked and hit a low-voltage line or something similar. But, as it turns out, that wasn\'t the case. Instead, something unprecedented occurred, a \'zero energy\' event: the power grid in Spain and Portugal went down completely.As we can see from the following graph coming from Red Eléctrica Española (transmission system operator responsible for managing the Spanish electricity system), at 12:35pm suddenly 15 GW of generation power went \'missing\'. As the prime minister would explain during a press release: "in 5 seconds, 60% of the country\'s demand disappeared from the system". The interconnected power system is one of the most complex systems ever built. It is beyond the scope of this article to provide a detailed technical assessment of all possible non-cyber scenarios that could contribute to a \'black swan\' event. In fact, investigations into large-scale power outages typically take months to reach reliable conclusions. Therefore, I will leave this task to the experts, who have access to the necessary data to conduct such a complex analysis.However, there is specific information suggesting that a potential cyber attack could be behind this. For example:https://www.larazon.es/economia/cni-apunta-ciberataque-como-posible-causa-apagon_20250428680f7e19319ae75da4ba8c32.htmlThe President of the regional government of Andalusia (Spain) claims that, after consulting with cybersecurity experts, the massive power outage is likely the result of a cyber attack.https://www.eleconomista.es/energia/noticias/13337515/04/25/juanma-moreno-apunta-a-un-ciberataque-como-posible-causa-del-gran-apagon-en-espana.htmlMeanwhile, top European figures such as the European Council p |

Les hacktivistes ciblent l'infrastructure critique, passez à des ransomwares Hacktivists Target Critical Infrastructure, Move Into Ransomware (lien direct) |
Présentation
Selon un nouveau rapport Cyble, les hacktivistes vont de plus en plus au-delà des activités traditionnelles telles que les attaques DDOS et les défaillances de sites Web en infrastructure critique plus sophistiquée et attaques de ransomwares.
Dans un rapport pour les clients, Cyble a déclaré que le hacktivisme s'est «transformé en un instrument complexe de guerre hybride» avec la montée en puissance des groupes qui ont adopté des techniques d'attaque plus sophistiquées plus généralement associées aux acteurs de l'État-nation et aux groupes de menaces motivés financièrement.
Hacktivism "ne se limite plus aux explosions idéologiques marginales", selon le rapport. «Il s'agit maintenant d'un appareil de cyber-insurrection décentralisé, capable de façonner les récits géopolitiques, de déstabiliser les systèmes critiques et de s'engager directement dans des conflits mondiaux à travers le domaine numérique.»
Le rapport CYBLE a examiné les groupes hacktiviste les plus actifs au premier trimestre de 2025, les nations et les secteurs les plus ciblés, les techniques d'attaque émergentes, et plus encore.
