NASA computers have always been treated as one of the safest systems out there, but a few skilled hackers have been able to hack the American spacial agency over the years. Only in 2011, NASA servers were hacked 13 times according to Paul Martin, the agency's inspector general.
"Some NASA systems house sensitive information which, if lost or stolen, could result in significant financial loss, adversely affect national security, or significantly impair our nation's competitive technological advantage," Martin said during a congress for the U.S. House Committee on Science, Space and Technology.
According to data from Martin, in 2011 a group of hackers under a China-based IP managed to get full access and control over the agency's servers. Earlier last year, about 150 information and passwords from NASA employees got stolen and not only that some hackers have also modified some of NASA's logs.
Martin did not go through each of the 13 attacks but he said the agency has taken some measures to make it even stronger.
