The Cyber Crime Branch of Maharashtra police said the small and medium-level Internet Service Providers (ISPs) in the state are facing ‘Distributed Denial Of Service’ (DDOS) attack by hackers on an unprecedented scale.
The police have registered an FIR in this regard.
Inspector General of Police (Cyber Crime) Brijesh Singh said, “Some unknown people are involved in crashing the ports of Internet Service Providers by making lakhs of requests at a particular terminal at a particular time, which we call ‘Distributed Denial of Service’.”
Cyber Crime department was taking all possible measures to nab the perpetrators, he said.
“We have registered an FIR and started tracking down the operators who are trying to crash the servers or ports of ISPs,” he said, adding that the attack has slowed down the internet services and affected subscribers of ISPs.
Representatives of ISPs on Saturday met Singh and apprised him of how the attackers were programming multiple Internet Protocol (IP) addresses to log on to their servers at the same time, causing the servers to crash.
Suppose a person runs an online reservation centre and particular server is equipped to handle 100 users at a time.
DDOS perpetrators create 1,000 log-ins by pre-programming at one time and send lakhs of requests at the same time, which subsequently crashes the port or the servers.
“Due to which person is compelled to move to another ISP to carry on business,” said the senior IPS officer who is an IT specialist.
One of the owners of ISP firms who met Singh said ISPs have been hit for the last one week in Mumbai, Thane and Pune, affecting their business severely.
