On October 2, 2025, the Indonesian cyber world was abuzz with the news of the arrest of Bjorka, the hacker, a mysterious figure who had been feared for leaking the sensitive data of millions of citizens. The Jakarta Metro Police arrested a man with the initials WFT (22) in North Sulawesi, who confessed to being the mastermind behind the claim of hacking 4.9 million bank customer data. This case is not only a victory for cyber authorities but also a reminder of how vulnerable personal data security is in the digital age. Who exactly is Bjorka? What has he done? Read the complete review below.
Who is the Bjorka Figure Who Was Arrested? Profile and Background
WFT, born in 2003, hails from Totolan Village, Kakas Barat District, Minahasa Regency, North Sulawesi. He was arrested at his girlfriend’s house on September 23, 2025, after the police traced his digital footprint for 6 months. His background is simple: An orphan, did not graduate from vocational high school, and unemployed. He learned hacking autodidactically through social media, not a formal IT expert. In cyberspace, he has been active since 2020 with the X account @bjorkanesiaa and dark web usernames like SkyWave, Shint Hunter, and Opposite6890—all to avoid tracking. His motive? He claimed to protest against government cyber weaknesses, but in practice, it was more about extortion and selling illegal data via cryptocurrency.
Bjorka’s Actions: From 2022 Data Leaks to the 2025 Bank Hack
Bjorka first caused a stir in 2022 by leaking millions of data: Jokowi-Gibran’s tax ID numbers (NPWP), BIN documents, KPU data, MyPertamina data, and citizens’ driver’s licenses. The data was sold on the dark web, sparking national concerns about the leakage of Indonesian personal data. The police suspected WFT was involved via reposts, even though he was still a teenager at the time.
The peak of the case in 2025: Last February, he uploaded a database screenshot on X, claiming to control 4.9 million customer data from a private bank (allegedly BCA). DM threats to the bank’s official account led to a police report on April 17, 2025. Other data claimed: Health and government sectors. His method was simple—manipulating old data for sensation—but the impact was significant: Risk of identity theft and fraud.
Chronology of Bjorka’s Arrest by the Jakarta Metro Police
The case began with a report from a private bank. The police investigated the account @bjorkanesiaa, tracking dark forums since December 2024. Evidence seized: 3 cellphones, a tablet, SIM cards, and a flash drive containing 28 fake emails. A press conference on October 2, 2025, revealed WFT as the main suspect. “This may be Bjorka 2020, but we are investigating further,” said AKBP Fian Yunus, Deputy Director of Cyber Crime Investigation at the Jakarta Metro Police.
Legal Threats: 12 Years in Prison for Bjorka Hacker
WFT is charged under the ITE Law Articles 30, 32, and 35: Illegal access, data forgery, extortion. The maximum penalty is 12 years in prison plus a fine of Rp12 billion. The police urge victims to report to expand the investigation. This case is an important precedent for enforcing Indonesian cyber security.
Netizen Reactions on X: Skeptical to Allegations of Issue Diversion
On X, this news went viral with thousands of posts. Many were skeptical: “A fake hacker, looks like a kid!” or “Why was he caught so easily, but Sifester got away?” Some accused the authorities of diverting attention from political issues such as Gibran’s school. However, the majority appreciated it: “Finally, there’s progress in cyber!”
