Description
On November 9, 2025, Indian businessman Vijay Mallya’s Twitter account was compromised by a hacker group identifying itself as Legion. The attackers hijacked the account and began leaking extensive personal and sensitive information attributed to Mallya, including his physical address, phone number, details of assets held at multiple international banks, and specifics about his business holdings. Legion claimed responsibility for the breach via email correspondence with IBTimes UK, describing themselves as international "Blackhats" targeting corrupt systems but declining to disclose their intrusion methods. The group’s statements suggested potential exploitation of an undisclosed zero-day vulnerability, a type of attack leveraging unknown software flaws that lack existing defenses. Concurrently, Legion asserted involvement in compromising Indian politician Rahul Gandhi’s Twitter account and issued threats to release additional data related to Mallya and the Congress party. The leaked information, which included financial and personal records, was not independently verified by media outlets at the time of reporting.
Mallya became aware of the breach on the morning of November 9 and publicly alleged his accounts were being subjected to blackmail attempts. Legion categorically denied these accusations, dismissing them as false. The incident occurred against the backdrop of Mallya’s existing legal and financial troubles, including over Rs 9,000 crore in unpaid loans and the revocation of his Indian passport. The attack’s immediate impact centered on the unauthorized exposure of sensitive personal and financial data, amplifying reputational and legal risks for Mallya. No details regarding account recovery, containment measures, or law enforcement involvement were disclosed in available reports. The hackers’ threats of further leaks against political entities introduced broader implications for data security among high-profile Indian public figures, though no subsequent disclosures were confirmed within the reporting period.
