The state’s Information Technology department has managed to contain the spread of Locky virus, a file-encrypting ransomware, in computer systems at Mantralaya and all the data are safe, a senior official claimed.

The virus had affected about 150 computers, mostly in Revenue, Public Works Department and some isolated computers in other departments of Mantralaya and these computers have now been isolated and being sent for forensic tests, Principal Secretary, IT department, V K Gautam, said.

All the data on the Maharashtra Local Area Network (Maha LAN) are safe, he said. “The virus first showed its presence around Friday last week, which probably sneaked into the Maha LAN through a spam mail,” Gautam said. Around 53,000 computers are on the Maha LAN.
