NEW DELHI: Several broadband connections of state-run MTNL have been impacted in the national capital after a malware attack.The issue, which company officials claim is “under control now”, impacted services at many households with malfunctioning of the broadband services. The impact on enterprise connections is still not clear, though sources say that operations were also impacted there.A top official at MTNL said that the company had noticed the issue since Thursday. “We have been taking action to sort out the matter, and are confident that the issue will be rectified very soon,” the official, who requested anonymity, said.The financially-strapped telco, which is struggling to stay afloat, said that it is adopting a variety of measures to tackle the issue. “The modem has to be re-configurated to manage the problem.”For subscribers who are calling its helpline, the company is providing immediate “on-phone rectification” helpline. “We are also contacting subscribers on our own. Apart from this, we are also replacing the modem of subscribers where there is a serious issue due to the malware.”MTNL is also advising its customers to follow certain steps to re-boot the modem. “There is a reset button on every modem that needs to be pressed for a few seconds. This is equal to taking the system on to the factory settings mode.”The telco has not been able to detect the origin of the malware attack. Asked whether the company is also coordinating with the Ministry of IT to look into the matter, the official said he is not aware of any such exercise.A top official at BSNL said that no such issue has been noticed in the company’s mobile network.The government has asked various telecom and banking companies to be careful about virus attacks and malware, especially as the country moves over to digital transactions.
