Chinese Hackers Breached US Embassy in Havana During Trump Blockade Threats, Researchers Find

Chinese state-linked hackers reportedly breached email systems at the United States Embassy in Havana during a period of heightened geopolitical confrontation between Washington and Caracas. According to findings from the cybersecurity firm Gambit Security, cited in a Bloomberg report, the campaign targeted sensitive diplomatic communications and coincided with escalating military and economic pressure on the island nation.

The operation began in January and compromised the accounts of 68 officials, including the Cuban ambassador and the deputy chief of mission, researchers said. The breach occurred shortly after a US raid in Venezuela and roughly coincided with a decision by the Trump administration to halt oil deliveries to Cuba—measures that contributed to widespread blackouts across the country. The campaign unfolded against a backdrop of renewed tensions reminiscent of Cold War dynamics, with Trump publicly threatening a naval blockade similar to operations preceding past US interventions in the region.

Gambit Security researchers concluded that the campaign appeared strategically timed, exploiting the window of diplomatic upheaval to conduct espionage on US personnel and communications. The incident highlights the intersection of cyber operations and conventional geopolitical pressure, with state actors leveraging digital intrusion to gather intelligence during moments of acute regional conflict. The breach raises concerns about the exposure of diplomatic correspondence and the potential for subsequent intelligence exploitation, though the full scope of data accessed remains under investigation.
