The Atacama Large Millimeter Array (ALMA) astronomical observatory in Chile became an unlikely target for a cyberattack this week when unknown assailants knocked its systems offline.
It's maintained in international partnership between Canada, Chile, the EU, Japan, South Korea, Taiwan, and the United States, and, built at the cost of $1.4 billion, is the most expensive terrestrial-based telescope in existence.
The attack, which happened last weekend, has forced "the suspension of astronomical observations and the public website," the observatory said in a statement on Wednesday.
