2 December 2002 Venezuela, Bolivarian Republic of Offshore Intrusion


The national oil company of Venezuela is a major entity responsible for a substantial portion of the country's economic activity and its contribution to local and world's oil supply.

According to sources, during national strike movement, an intrusion targeted OT systems of the company, as well as centrally controlled operations. An major impact would have been Programmable Logic Controllers (PLCs) at a port facility being wiped out.

Due to the intrusion, Venezuela's oil production faced a significant decline, dropping from 3 million barrels per day (BPD) to just 300 thousand BPD. Oil production had to be stopped during eight hours, a tanker waiting in the port could not be provided with oil, and PLCs had to be reinstalled.
