Four New Types of Holiday Scams Revealed by ESTsecurity on the 25th. ESTsecurity.

East Security, a cybersecurity subsidiary of ESTsoft, issued a warning on the 25th by unveiling four new types of holiday scams that exploit AI technology.

According to East Security, the new types include: ▲ Deep voice and deepfake video call scams that can be completed in just a few seconds using a voice sample ▲ AI-generated, customized phishing messages with correct grammar ▲ 'All-in-one account theft,' which targets banking, messenger, and social media accounts simultaneously ▲ And ultra-precise impersonation scams combined with a series of recent personal data leaks.

East Security specifically warned that this technology, which can synthesize the voice and face of an acquaintance using a short audio clip, may be abused to contact people while impersonating a family member or relative. The company recommended that families set up a verification method using a secret code known only among them, and that in cases where there is an urgent request for money, they should call back using the number they already have to confirm.

With advances in generative AI, the awkward or unnatural expressions that once characterized phishing texts have disappeared. Caution is also necessary when receiving customized scam messages made to appear real, using leaked personal information such as the recipient's name and affiliation. The company explained that by installing a remote control app via a message disguised as a delivery notification or traffic fine, users could have their accounts on banking, messenger, and other services compromised. As leaked personal information can be used for secondary phishing attacks targeting acquaintances, it is critical to block the installation of apps from unknown sources entirely.

An East Security representative emphasized, "Traditional scam detection methods that relied on human senses are now themselves targeted by AI attacks. It is essential to take preventative steps, such as checking for any personal information leaks and updating your passwords, and if you spot any suspicious circumstances, immediately report them to the National Police Agency (112) or the Financial Supervisory Service (1332) to prevent further damage."
