Through an upload on the Breached Forum site, hacker Bjorka made a new upload with the topic MyPertamina Indonesia 44 Million. The information was uploaded on Thursday (11/10), based on the information displayed.
Bjorka's account was viral on Twitter before it got restricted. Indonesian government already tried to find the person behind Bjorka, but only ended up arresting a young man who sold ice in East Java Province.

In this upload, Bjorka claimed to have data of around 44 million data originating from MyPertamina. The sold data is 30GB in size with 6GB compression.
From this information, the leaked data includes name, email, NIK, NPWP, telephone number, address, date of birth, gender, and even income (daily, monthly, yearly).
However, it is not yet known where the information regarding income can be obtained. It is possible that the data in question is related to the amount of expenditure or transactions made by the user.
This data is sold at a price of USD 25,000 or around Rp 392 million. Hacker Bjorka wrote the data can only be purchased using bitcoin (BTC).
"MyPertamina is a financial service platform from Pertamina that is integrated with the LinkAja application. This application is used for non-cash fuel payments at gas stations," Bjorka wrote in the upload.
Even though it has been uploaded, the information regarding this data leak cannot be confirmed. Bjorka himself had mentioned in September 2022, that he would upload information about Pertamina's data.
At that time, he said he would publish MyPertamina's database to support people who staged demonstrations related to the increase in fuel prices.
"To support people who are struggling by holding demonstrations in Indonesia regarding the increase in fuel prices. I will publish MyPertamina's database soon," the hacker wrote via his Telegram channel.
Even so, it is not certain whether his action this time is a continuation of Bjorka's statement a few months ago.
