Cofco's Argentina grains operations affected by cyber attack

BUENOS AIRES (Reuters) - Activity at ports operated by China's Cofco in Argentina's main grains hub of Rosario have been interrupted by a worldwide cyber attack, a local port manager said on Wednesday, the first sign that the virus had made its way to South America.

The computer worm was first seen in Ukraine on Tuesday, going on to affect port facilities ranging from Mumbai to Los Angeles. It hit Argentina on Wednesday, slowing wheat and fertiliser shipments and threatening to impact the flow of soybeans to the country's main client, China, at the height of export season.
