CBSE issues clarification after 19-yr-old claims he could change marks in CBSE's marking portal

After a 19-year-old claimed that he hacked into CBSE's OSM system, which was used for the first time this year to evaluate answer sheets, the board said the OSM system hadn't been compromised. "The URL: http://cbse.onmarks.co.in is the testing site only...There are no actual evaluation data, marks or other data held on that portal," CBSE said on Tuesday.
