The Financial Supervisory Service disclosed the voices of 12 voice phishing scammers who were reported more than five times among 937 voice phishing scammer voice reports received in the first half of this year through the 'Voice Phishing Guardian' and the Financial Supervisory Service's YouTube channel. The National Forensic Service determined whether the voices belonged to the same individual.

Based on the reported files, a video including the scammers' main tactics and exemplary responses from reporters was produced and released. The reporters' voices were altered and personal information was muted, but the scammers' voices were disclosed as is.

From the 10th to the 23rd of this month, 5,000 people who listen to 'This is the Voice' and leave comments will be entered into a draw to receive Americano gifticons.

The scammers mainly impersonate prosecutors and emphasize that the call is for investigative purposes. They explain case details as if they were actual prosecutors or investigators in charge of the investigation, using technical terms such as 'account freezing, third-party provision, evidence adoption, involvement, victim proof, and relevant penal code articles.'

They pressure victims by threatening to issue a summons if victim proof is not provided. They mention cases like 'identity theft' and 'violation of the Special Act on Prostitution,' pressuring victims by saying they will be investigated as suspects if they fail to prove their victim status. They also pressure victims not to hang up by threatening to issue a summons if asked to call back later due to being busy.

After reassuring victims that they do not require personal information, they then request financial information such as account details and balances, claiming it is necessary for asset protection settings. In loan impersonation voice phishing, they ask for acquaintances' personal information, saying it is needed for low-interest loans.

They also isolate victims by stating that call recordings with noise or third-party voices will not be accepted as evidence, leading victims to secluded spaces to block interference or help from others.

They induce victims to access fake prosecutor’s office websites via internet IP addresses. They have victims enter IP addresses instead of domain names to access fake prosecutor’s office sites, claiming to show official prosecutor’s office documents. Other posts besides the official document cannot be clicked or are poorly made.

The Financial Supervisory Service also introduced exemplary responses from reporters. When told that a reporter’s name was used for a mule account involved in fraud, the reporter asked why it was not found on the bank app and said they would check their own bank account list and contact them.

When given an IP address to check the prosecutor’s office document, the reporter said they would verify by entering the prosecutor’s office site through an internet search engine and requested the case number. Suspecting voice phishing, they responded by saying they would hang up and verify directly with the bank or prosecutor’s office or appear in person for investigation.

After accessing the IP address provided by the voice phishing scammer and finding that posts could not be clicked, the reporter suspected voice phishing and immediately hung up. There was also a case where the reporter suspected the caller was not a prosecutor and requested an ID card.

A Financial Supervisory Service official said, "The voices of voice phishing scammers reported by the public are valuable materials for catching scammers and preventing voice phishing," and urged, "Please actively report to the 'Voice Phishing Guardian' on the Financial Supervisory Service website."
