JAKARTA – Indonesia’s new data protection task force is suing a hacker behind a series of data breaches linked to 1.3 billion registered mobile numbers and 105 million voters, and to a journal of the president’s correspondence, among others.

The hacker, who goes by the pseudonym Bjorka and claims to be based in Warsaw, Poland, sold stolen data, including that of Indonesian state-owned companies, mobile operators and the General Election Commission, on the BreachForums hacking forum in the past. a few weeks.

Bjorka also leaked a log of confidential incoming and outgoing documents between President Joko Widodo and the state intelligence agency.

The day after a senior IT applications official called on Bjorka to stop disclosing Indonesians’ personal data at a September 5 press conference, the hacker boldly told the government to “stop being an idiot ” in a message from BreachForums.

On Twitter, Bjorka also said those investigating the hack wouldn’t know where to start and mocked public figures such as Public Enterprises Minister Erick Thohir, telling him to give up his hopes for the presidency.

At least three of Bjorka’s Twitter accounts have been suspended.
