Mexico’s Defense Chief Says 2022 ‘GuacamayaSedena Breach Was Caused by Human Error

The defense chief attributed the 2022 breach to human error, with encrypted systems now described as standard practice.

Overview

  • Ricardo Trevilla confirmed for the first time that the emails leaked in 2022 were Sedena’s, ending two years without an official explanation of their origin.
  • He said the compromised information was not encrypted and moved over regular internet channels, characterizing the incident as a lapse by personnel rather than a system failure.
  • Trevilla stated that all Armed Forces communications now operate on encrypted platforms and that security and monitoring protocols have been reinforced.
  • He rejected reports of a new comparable intrusion allegedly linked to members of the University of San Diego, saying there is no indication of access to classified data.
  • The 2022 hack, attributed to the Guacamaya collective, exposed roughly six terabytes of government data and has been cited as one of Mexico’s largest cyber incidents.
