Department Of Telecommunications: The officer, however, said that telecom operators have informally shared with the department that the leaked information claimed in the ClouSEK report seems to be a compilation of old data sets of telecom subscribers and it is not due to any vulnerability in their system.
Cybersecurity firm CloudSEK has claimed that its researchers have found that hackers are selling 1.8 terabyte of database comprising 750 million Indian mobile consumers on the dark web.
The cyber intelligence firm, which engages with government cyber security CERT-In, said that the breach came to light on January 23 and as part of responsible disclosure CloudSEK has informed the relevant authorities and organisations possibly impacted by the breach. "The data, available for sale, is compressed to 600GB and uncompressed to 1.8 TB, posing significant risks to both individuals and organizations. The threat actor has demanded USD 3,000 for the entire dataset," the report said.
Researchers at cybersecurity firm CloudSEK found that CYBO CREW affiliates CyboDevil and UNIT8200 have recently advertised a massive “Indian Mobile Network Consumer Database” for sale.
