Maharashtra Cyber collated information about these attempts and most of them were found to have originated in Chengdu area in China, he said.
"According to our information at least 40,300 cyber attacks were attempted in the last four-five days on the resources in Indian cyberspace," he said.
The attacks aimed at causing issues such as denial of service, hijacking of Internet Protocol and phishing, Yadav added.
Indian Internet users should pay attention to the threat of such attacks, create robust 'firewalls' and conduct cyber security audits, the IGP said.
According to Maharashtra Cyber officials, these hackers are suspected to have database of some 20 lakh Indian email IDs.
Indian government officials as well as private Internet users should especially guard against phishing, where attempt is made to obtain confidential information such as passwords or pass-codes by sending a fraudulent email or text message, they added.
There could be phishing attempts by impersonating, online, government agencies, departments and trade associations overseeing the disbursement of government fiscal aid, they said.
