Voice-phishing losses in South Korea hit 1.2578 trillion won in 2025, lawmakers were told on Sept. 29, crossing the one-trillion-won threshold for the first time in police and financial-regulator records. The figure, released during National Assembly audit season, rose 47.2 percent from 854.5 billion won in 2024 and nearly tripled the 447.2 billion won reported in 2023.

Although reported case counts fell from roughly 30,000 in 2021 to 23,360 last year, the average loss per incident climbed to about 53.84 million won—more than double the 25 million won typical in 2021. Criminals are running fewer calls but aiming each one at life savings, prosecutors’ impersonation scripts, and cryptocurrency cash-out paths that outrun bank freezes.

Institution scams dominate

Scams that pretend to be prosecutors, police, or the Financial Supervisory Service accounted for 988.4 billion won in 2025, or 78.6 percent of all voice-phishing damage. That category alone approached one trillion won, up from 236.4 billion won in 2023. Attackers borrow official hotline numbers, spoof caller ID, and coach victims through “security investigations” that end with transfers to mule accounts.

Data submitted to the National Assembly’s Public Administration and Security Committee and the Science, ICT, Broadcasting, and Communications Committee also showed that 94 percent of initial contact in 2025 came by phone or text message, reflecting how mobile-first the fraud economy has become.

Who is losing money

Contrary to stereotypes about elderly victims, people aged 20 and under logged the highest case counts among age bands in several datasets reviewed by lawmakers—5,770 incidents in 2025—even as per-victim losses skew older because of accumulated assets. Fraudsters tailor social-engineering scripts to gig workers, students, and first-time investors familiar with mobile banking but less practiced at verifying government processes.

Democratic Party lawmaker Son Myeong-su and People Power Party lawmaker Kwon Young-jin each published complementary cuts of the same underlying police and FSS tables, highlighting bipartisan pressure for compensation reform.

Recovery rates stay thin

The Financial Supervisory Service froze 100,307 suspicious accounts in 2025, yet the refund rate for confirmed fraud sat near 26.3 percent, according to materials cited in committee hearings. By the time a payment stop order lands, gangs often launder proceeds through crypto exchanges, cash handoffs, or rapid re-transfers, leaving empty accounts for investigators.

Son argued that annual losses above one trillion won with sub-30 percent recovery justify a statutory compensation fund akin to deposit insurance. Government witnesses countered that a unified response team launched in September and tighter telco blocking rules beginning in October had already slowed monthly damage, though full-year 2026 data will be the first clean test.

Policy crossroads

Seoul’s response mix includes faster number blocking, mandatory fraud warnings on banking apps, and international cooperation to seize offshore wallets. Critics say prosecution-led scripts succeed because state agencies still rely on phone callbacks rather than in-app verified messaging, giving scammers room to mimic tone and urgency.

For households, the Assembly numbers are a reminder that fewer reported crimes does not mean safer phones. Until impersonation arrests scale with damage, a single answered call can still wipe out decades of savings—and the 2025 ledger shows that outcome is no longer rare.

Banks and carriers under scrutiny

Committee members pressed lenders on why real-time fraud analytics still lagged spoofed prosecutor hotlines, and asked mobile operators to explain how scam numbers reappear hours after blocking. The FSS noted it is testing stronger authentication for large transfers, including cooling-off periods when a new payee is added during an active call. Victim advocates want those controls default-on rather than opt-in, arguing that stressed callers cannot find hidden settings in time.

Police statistics on arrests versus losses will be the next political flashpoint. If 2026 damage falls while convictions rise, the September task force will claim credit; if losses stay elevated, the trillion-won debate will move from audit hearings to campaign pledges for state-backed restitution.

Audit staff said they will track quarterly loss tallies through 2026 to test whether September enforcement packages change the trajectory.
