Those already fearful of the Big Hadron Collider’s potential Earth-ending capabilities might want to turn away for this one, as it looks like the situation has managed to get a bit more hazardous, with a team of hackers apparently successful in mounting an attack on a system that’s “one step away” from the personal system that controls of one of the LHC’s big detectors. According to The Telegraph newspaper, the group, calling itself the “Greek Security Team,” left behind a half a dozen files on the system and damaged one CERN file, in addition to displaying the page above on the cmsmon.cern.ch website, which still remained inaccessible as of Friday. Somewhat disconcertingly, one of the scientists working at CERN simply described the incident as a “scary experience,” with a CERN spokesperson further adding that they thought it was just someone “making the point that [the system] was hackable.” Um, okaaaay.
