The BBC reports that a new threat targeting infrastructure in the energy industry has been uncovered by security specialists.
The attack, known as Shamoon, is said to have hit "at least one organisation" in the sector.
Shamoon is capable of wiping files and rendering several computers on a network unusable.
On Wednesday, Saudi Arabia's national oil company said an attack had led to its own network being taken offline.
Although Saudi Aramco did not link the issue to the Shamoon threat, it did confirm that the company had suffered a "sudden disruption".
