In December 2002, PDVSA, Venezuela’s state oil company became embroiled in a bitter strike that saw extensive sabatoge. According to a report in Oil Daily, Ali Rodriguez (the head of the oil company) stated:
“[…] we have suffered many acts of sabotage at the terminals, the refiners, and even to some well-heads in Lake Maracaibo. There were even instances of computer hacking which did a lot of damage since much of the operation is centrally controlled by computer.”
Someone, possibly an employee involved in the general strike, remotely accessed a program terminal to erase all PLC programs in port facility.
