Voice Phishing Ring Busted: Scammers Posed as Prosecutors, Tricked Victims into Sexual Exploitation

A ruthless voice phishing syndicate, orchestrating its operations from Bangkok, Thailand, has been brought down by South Korean authorities. The group, comprised of 11 arrested individuals, specialized in impersonating high-ranking officials from the prosecution service and the Financial Supervisory Service.

Their elaborate scheme involved coercing victims into "self-imprisonment" in motels under the guise of resolving fabricated legal issues. The scammers then demanded "public money" for alleged case resolution, while also engaging in sexual exploitation by demanding nude photographs for fake "body searches" conducted as part of a supposed pre-arrest procedure. This resulted in the creation of sexually explicit material from the victims.

According to the Seoul Metropolitan Police Agency's Financial Crime Investigation Unit, the syndicate operated from May to December last year. They targeted 68 victims, extorting a total of approximately 6.7 billion won (about $5.1 million). The group was structured with distinct roles, involving a "first line" impersonating investigative officers, a "second line" posing as prosecutors, and a "third line" acting as Financial Supervisory Service employees, who would sequentially approach the victims.

The victims, predominantly in their 20s and 30s, were tricked into believing their bank accounts were involved in criminal activities. They were then directed to fake websites of the prosecution service to view fabricated arrest warrants. Subsequently, a scammer posing as a prosecutor would call, demanding the victim "self-imprison" in a nearby motel for a "summary investigation" and sending forged documents for a "protection observation" and "body search."

Police have identified the group as a "criminal organization" due to their strict internal discipline and role-based hierarchy. The 24 members, including 20 Koreans and 4 Chinese nationals, reportedly had their passports confiscated by the leaders. Strict rules, such as prohibiting personal phone use during work hours and destroying related data upon leaving, were enforced, with violations leading to threats and physical abuse. Police have secured approximately 157 million won in illicit gains through pre-indictment preservation measures and are continuing to track down the remaining proceeds of the crime.

You must not comply if prosecutors or the Financial Supervisory Service claim you are involved in a crime and demand a body search or ask for money such as public funds for case resolution. Report it to the police immediately.
