Description
On Monday, May 19, 2025, at 8:48 a.m., internal staff at Noroeste Media detected the first failures affecting the website www.noroeste.com.mx and immediately reported the incident to the technical team. The technical team confirmed that the event constituted a directed cyber attack after an initial assessment. The attack caused instability in the platform, interfering with content updates and the operation of its applications.
In response, the support team deployed mitigation measures, including the installation of a server designed to filter malicious traffic. Additionally, the historical notes section of the site was temporarily disabled, as it was identified as a possible target of the attack. These actions were taken after the technical report indicated that the attack was directed and required immediate containment.
Analysis conducted with the assistance of CloudFlare provided information on the attack's origin, covering a window of 12 to 24 hours before 5:00 p.m. on the same day. The preliminary findings indicated that the attackers used IP spoofing to evade protective layers, which prevented requests from being recorded in the site's statistics. Suspicious requests originated from 20,764 distinct IP addresses located in Russia, the United States, Mexico, Canada, Romania, and other countries. The technical report noted that these indicators support the hypothesis of a sophisticated and carefully directed attack.
