The digital world has become the new battleground for international powers, where each attack can have profound and lasting repercussions. Recently, a major cyberattack struck the systems of the U.S. Treasury, revealing the vulnerability of the technological infrastructures of a state renowned for its defensive capabilities. This incident occurs in the context of intense rivalry between the United States and China, as Washington accuses presumed hackers backed by Beijing of being behind the intrusion. For its part, China firmly rejects these accusations, labeling them as unfounded and denouncing a smear campaign orchestrated by U.S. authorities. More than just a mere digital incident, this case sheds light on the growing geopolitical tensions around cybersecurity and the difficulty of identifying those responsible in an increasingly interconnected world.
