Telecom network fraud methods are constantly evolving, posing a threat to public property security. Major types include 'screen sharing' fraud, which involves inducing victims to enable screen sharing to obtain personal banking information for theft; 'AI deepfake' fraud, which utilizes technology to synthesize false audio and video, gaining trust before misleading victims into transferring money or providing sensitive information; false online investment fraud that uses high returns as bait to lure individuals into investing before siphoning off funds; and fake transaction fraud in online gaming products, which deceives players into making offline transactions through fictitious trading information, resulting in financial losses. Prevention measures are necessary.
