A phishing campaign targeting Bank Rakyat Indonesia (BRI) customers utilizes WhatsApp and SMS to trick users with a fake 150,000 IDR service fee increase. The attack uses a fraudulent “BRImo” portal to harvest credentials and real-time OTPs to seize control of mobile banking accounts.


Bank Rakyat Indonesia (BRI) “Service Fee Change” Scam
Target: Customers of Bank Rakyat Indonesia (BRI)
Threat Level: Critical (BRIMO Mobile Banking & OTP Theft)
Phishing Method Description
This attack uses a “Price Hike Scare” tactic. Scammers distribute fraudulent messages via WhatsApp or SMS (Smishing), claiming that BRI is updating its monthly service fee to a much higher amount (e.g., 150,000 IDR). To “keep the old rate” or “refuse the increase,” the victim is pressured to click a link and provide their details.
The link leads to a high-fidelity clone of the BRIMO (BRI Mobile) login portal. This phishing kit is specifically designed to harvest:
Username and Password
ATM/Debit Card Number
Mobile Phone Number
SMS OTP (One-Time Password): The fake site prompts the victim for the 6-digit code in real-time. The attacker uses this code to authorize a fraudulent transfer or to register the victim’s account on their own device.
⚠️ Red Flags to Watch For
The Deceptive URL: The official domain is bri.co.id. Phishing sites use lookalikes such as bri-tarif-baru.com, konfirmasi-bri.net, update-layanan-bri.online, or free subdomains like brimo-login.web.app.
Urgent WhatsApp Messages: BRI officially communicates through verified channels. If you receive a fee-change notice from a random mobile number on WhatsApp, it is 100% a scam.
Requesting your PIN/OTP: BRI will never ask for your mobile banking PIN or SMS OTP through a website link to “cancel a fee.”
🛡️ How to Protect Yourself
Use the BRIMO App: Trust only the notifications and settings found inside your official BRIMO mobile app.
The “No Link” Rule: BRI states they will never send links via WhatsApp or SMS asking for personal login credentials. Always type www.bri.co.id manually into your browser.
Verify with Contact BRI: If you receive a suspicious message, call the official BRI hotline at 1500017 or visit an official branch to verify any policy changes.
OTP Security: Treat your SMS OTP as a secret key. Never share it, and never enter it on a page reached through a link.
💡 Expert Security Tip:
This is a Social Engineering & Real-time Interception attack. Scammers create a fake “financial threat” (the new fee) to make you panic and give up your OTP. Remember: Banks do not ask you to “log in and verify” to cancel a service fee. If a site asks for your Username and OTP at the same time, it is a phishing trap.
