Hacking trees

Hackers have accessed Brazilian government computer systems and helped 107 companies obtain permits that enabled them to fell over £546million ($833m) worth of timber illegally....

"By hacking into the permit system, these companies have made their timber shipments appear legal and compliant with the forest management plans. But in reality, they're trading illegal timber which is making the problem of deforestation worse, and a lack of control and policing in the areas they're logging means they think they can get away with it."
