Cybercrime suspect from North Sulawesi accused of data breach, extortion attempt, and dark web activity
Jakarta police have arrested a 22-year-old man from Minahasa, North Sulawesi, who allegedly posed as the notorious hacker “Bjorka” and claimed responsibility for breaching the personal data of 4.9 million Indonesian bank customers. The suspect, identified as WFT, now faces charges under the country’s cybercrime laws.
Six-Month Investigation
The Cyber Crime Directorate of Polda Metro Jaya confirmed that WFT was arrested on September 23 in Totolan Village, Minahasa, following a six-month probe into illegal data access. Officials said he had been active on the dark web since 2020, allegedly obtained and traded stolen data from banks, healthcare providers, and private companies.
False Identity as ‘Bjorka’
Police stated that WFT operated social media accounts under the names “Bjorka” and “@bjorkanesiaa” on X (formerly Twitter). Using these accounts, he posted screenshots of private bank accounts and messaged an official bank channel, claiming to have hacked millions of customer records.
Attempted Bank Extortion
Investigators allege the suspect tried to extort a private bank by threatening to release sensitive data. Police said the attempt failed after the bank ignored the threats and filed a report instead. No money was transferred to the suspect.
Evidence Seized
Authorities seized digital evidence from WFT’s computer and mobile phone, including files containing customer account details. Police also found proof that he had advertised and attempted to sell stolen data on multiple platforms for tens of millions of rupiah.
Legal Consequences
WFT has been formally named a suspect and detained. He has been charged under multiple articles of Indonesia’s Electronic Information and Transactions (ITE) Law, including illegal access, data manipulation, and fraud. If convicted, he faces up to 12 years in prison.
Broader Cybersecurity Concerns
Police stressed that the case highlights growing threats from hackers exploiting the dark web to trade stolen personal data. Authorities urged financial institutions to strengthen security measures and encouraged the public to remain vigilant against scams linked to data leaks.
The arrest of the self-styled hacker “Bjorka” underscores Indonesia’s escalating battle against cybercrime. While police prevented a major extortion scheme, the case raises broader concerns about data protection, digital law enforcement, and the risks posed to millions of Indonesians whose personal information circulates on the dark web.
