Chilean Army Email Leak

In December 2019, as Chile was gripped by massive social protests, Anonymous Chile announced that it had compromised six email accounts of high-ranking Chilean Army officials. The hackers exfiltrated a large quantity of internal communications spanning from 2015 to 2019. The leaked data included sensitive information about military intelligence operations, international relations and cooperation with foreign militaries, financial records and procurement data, and internal communications about the military's role in responding to civil unrest. Anonymous stated that the leak was intended to expose the Chilean Army's role in suppressing protests and alleged human rights violations during the 2019-2020 Chilean protests (Estallido Social). The data was released to journalists and published online.

Chile experienced massive social unrest beginning in October 2019, with protests demanding economic reforms, an end to inequality, and accountability for alleged human rights abuses by security forces. The military was deployed to assist police, resulting in accusations of excessive force, torture, and extrajudicial violence.

Anonymous gained access to six email accounts, likely through credential compromise, spear-phishing, or exploitation of vulnerabilities in the Army's email infrastructure. The extraction of four years of emails suggests sustained access to the compromised accounts.
