A cybersecurity attack has cancelled all online and in-person classes at Saskatchewan Polytechnic until at least Wednesday. In a statement, Sask. Polytechnic says it’s taking the matter “very seriously” and is working closely with “industry experts to minimize the extent of the impact.” The school says at this point there is no reason to believe that any personal information has been stolen. The first priority is restoring online classes. The extent of the hack is still being investigated.
