In March 2016 the Swedish Security Service realized what happened, and started an investigation, warning other government agencies that unauthorized foreigners were now in control of their IT systems after the STA had bypassed necessary security checks just to expedite the transition to the new IT system as they wanted to fire local IT staff (and many already found new jobs themselves).
