The Seoul Eastern District Prosecutors' Office voice phishing joint investigation division closed on Friday after four years of cross-agency raids, a restructuring that coincides with new scam types filling the gap left by declining call-center fraud.
Numbers prosecutors cite
Chief Prosecutor Lee Taesoon's team said it booked 1,381 members and associates of organized fraud rings, indicted 526 under detention, and recovered 36 billion won in criminal proceeds since July 2022. The unit combined about 50 specialists from prosecution, police, the National Tax Service, customs, the Financial Supervisory Service and immigration authorities.
Investigators targeted call centers, relay devices, fake bank accounts and fraudulent SIM card brokers. Last year they dismantled a Cambodia-based enterprise ring led largely by Chinese nationals, booking 48 members and indicting 23 under detention. They also broke a no-show scam crew that extorted about 3.8 billion won from 215 small-business owners through real-time overseas coordination.
What replaces the task force
Authorities say routine prosecution and police financial-crime desks will absorb caseloads after the joint unit dissolves, using playbooks developed during the four-year surge. The timing matters because police data show voice-phishing losses fell roughly 49 percent year-on-year through May, while impersonation and investment-chatroom fraud rose about 33 percent to 464.3 billion won in the same window.
Local governments join the warning chorus
Municipalities are publishing their own alerts as scammers pivot to welfare lures. Gunsan City in North Jeolla warned this week that fraudsters posing as livelihood-support staff demanded ID photos and verification codes for payments the city is not even running. Officials told residents to hang up and report suspicious texts to police.
Private firms such as Data Universe are plastering train-car posters describing three emerging patterns, a reminder that enforcement shifts alone cannot cover every social-engineering script. With bank data breaches also dominating headlines, Korean households face fraud pressure on two fronts: stolen credentials from financial institutions and polished lies on messaging apps.
Prosecutors said specialized financial-crime teams will inherit wiretap protocols developed with the joint unit, preserving rapid SIM-shutdown requests when new call centers surface.

Banks separately promised tighter vendor reviews after a week of data breaches, meaning fraud investigators and cybersecurity auditors will share evidence channels that did not exist when the joint unit launched in 2022.
