Bank BJB has issued a fresh advisory to its customers, warning of escalating digital fraud attempts targeting retail banking users.
The state-owned lender emphasized the importance of safeguarding personal data and conducting transactions exclusively through verified official channels, as cybercriminals increasingly exploit digital banking interfaces.
The alert arrives against a backdrop of heightened scrutiny on financial security in Indonesia.
Authorities are currently pursuing a Bulgarian national suspected of orchestrating a large-scale cybercrime operation that compromised thousands of accounts at Bank Jambi, a regional peer.
The Jambi Regional Police confirmed the suspect's involvement in the breach, highlighting the sophisticated nature of the attacks targeting Indonesian financial institutions.
This development underscores the persistent risks facing digital banking adoption in emerging markets.
