Strange calls starting with "+1" have a high chance of fraud! Criminal Bureau joins forces with Whoscall to develop AI radar to prevent traffic jams

Overseas number fraud presents diversified beginnings and frequently changing attack methods.

Fraudulent groups use overseas phone calls to commit large-scale fraud. Trust Technology's anti-fraud service Whoscall announced today (12th) that it will deepen its cooperation with the Criminal Police Department of the National Police Service to establish an "overseas fraud call AI radar" mechanism. Through cross-analysis of the Whoscall phone database and police information, it will continue to understand changes in overseas fraud numbers and publish attack trends.

Whoscall pointed out that overseas fraudulent calls have frequently changed their numbers recently. In August, the number of calls starting with "+422" surged, reaching 260,000 calls in a single month, accounting for 55.8% of overseas calls. After the casual method was exposed, the scammers quickly changed their targets. Between August and September, Whoscall identified nearly 200,000 unknown calls starting with "+1", of which "+1911" accumulated more than 70,000 calls. Recently, new types of numbers such as "+1749", "+1800" and "+1953" have appeared. Some of them exceeded 20,000 calls in a single month in September, becoming the focus of surveillance by the police and Whoscall.

Fraudulent groups often use VoIP Internet phone calls, number changes, and automatic dialing technologies to forge large numbers of overseas calls and pretend to be 165 anti-fraud hotline, police, NCC, or Financial Supervisory Commission, etc., to induce people to provide personal information or make transfers by using phone calls that are abnormal, involving money laundering or personal information leakage, etc.

Whoscall provides the function of blocking overseas calls in Android system.

The Criminal Police Department reminds that domestic government agencies and the 165 hotline will not contact the public through overseas telephone numbers starting with "+". Telecom operators will also issue voice warnings when receiving international calls. People should remember to "listen once, hang up twice, and check three times" and dial 165 directly after hanging up to confirm. In addition, Whoscall Android version provides the function of blocking overseas calls. You can set the block based on the beginning of the number to reduce the risk of receiving fraudulent calls.
