Bjorka Returns, Leaks 44 Million Data of MyPertamina

TEMPO.CO, Jakarta - A hacker Bjorka has returned and leaked more than 44 million data from the MyPertamina application belonging to state-run oil and gas giant Pertamina.

“MyPertamina is a digital financial service platform from Pertamina that is integrated with the app LinkAja. This application is used for non-cash fuel oil payments at Pertamina's public fueling stations,” the hacker wrote in his latest post titled 'MYPERTAMINA INDONESIA 44 MILLION' on an online forum called Breach Forums on Thursday, November 10, 2022.

The hacker claimed to have sold the data worth Rp392 million in the form of BitCoin. The leaked data consisted of 30 GB of uncompressed data and 6 GB of compressed data.

The data leak was carried out in November 2022 in CSV format, including name, email address, citizen identification number (NIK), taxpayer identification number (NPWP), phone number, address, date of birth, gender, income (per day, month, and year), and other data.

In his Twitter @bjorkapipa, Bjorka said the PeduliLindungi COVID-19 app will be the next target for data breaches.

The hacker returned after a month of disappearance. He has been widely discussed as he leaked the personal data of government officials and agencies.

The police had reportedly arrested a man, MAH, suspected of being Bjorka in Banjarsari Kulon Village, Dagangan District, Madiun Regency, East Java. However, the National Police spokesperson Inspector General Dedi Prasetyo said investigators were still unable to conclude whether the man was Bjorka. The investigation was still afoot.

Meanwhile, Corporate Secretary of Pertamina Patra Niaga Irto Ginting said his side is conducting an investigation into the data leak.

“Pertamina and Telkom are conducting a joint investigation to ensure the security of data and information related to MyPertamina,” said Irto to Tempo on Thursday, November 10, 2022.
