In Vietnam, authorities have noted that personal information is often collected from these channels or leaked from businesses that store customer data.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Individual pieces of information may seem harmless, but the danger lies in the fact that they are combined to form a complete picture of you.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"3200\" height=\"1580\" src=\"https:\/\/chongluadao.vn\/blog\/wp-content\/uploads\/2026\/08\/1.png\" alt=\"\" class=\"wp-image-5918\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">2. From fragments to a complete file<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Currently, the industry is called <em>Data Broker<\/em> (Data brokers) are making a living by collecting disparate pieces of information from public records, mobile applications, and loyalty cards, assembling them into detailed profiles, and selling them to anyone who pays. According to a report... <em>Fox News<\/em> Published on April 25, 2026, in less than 10 minutes and for a small fee, scammers can look up information on these sites to find out the victim&#039;s age, address, relatives, and even their previous place of residence, causing their vigilance to quickly crumble when they receive a call that correctly states those old details.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond simply buying and selling raw data, cybercriminals are also applying artificial intelligence to personalize their tactics through OSINT (Investigative Intelligence of Public Information on Social Media and News). A report from Kaspersky (Securelist) on August 19, 2025, indicates that cybercriminals are using AI-powered OSINT tools to compose emails and messages impersonating superiors or colleagues with extremely accurate internal details. Statistics from the ENISA Threat Landscape 2025 show that over 80% non-technical attacks globally currently involve AI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, short audio or video clips publicly available on social media also become perfect source material for AI to create technology. <em>deepfake<\/em>, This involves impersonating voices and images that closely resemble real people to commit fraud. This is a very real and significant threat, as a 2025 Gartner survey recorded that 621 organizations had faced attacks using this technology in fraudulent activities.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"3200\" height=\"1580\" src=\"https:\/\/chongluadao.vn\/blog\/wp-content\/uploads\/2026\/08\/2.png\" alt=\"\" class=\"wp-image-5917\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">3.
