According to sources, in 2010, a major player in the offshore rigging sector had an offshore rig suffered a comprehensive malware attack. The event occured when the rig leaf the construction yard in South Korea for its production site in Latin America (probably Brazil). The malicious software managed to infiltrate essential controls, including offline safety mechanisms.
