Someone really doesn't like Iranian industry. Quoting Slashdot:
"Iran disconnected computer systems at a number of its oil facilities in response to a cyber attack that hit multiple industry targets during the weekend. A source at the National Iranian Oil Company (NIOC) reportedly told Reuters that a virus was detected inside the control systems of Kharg Island oil terminal, which handles the majority of Iran's crude oil exports. In addition, computer systems at Iran's Oil Ministry and its national oil company were hit."Analysis, and my guess as to who could be behind this, on the other end of the fold.
