According to Hanoi City Police, many groups and forums on social networks are advertising services to recharge games, purchase applications and pay for cross-border services with unusually high discounts, from 30% to 70%. Services are often introduced in the form of payments on behalf of customers, selling cheap gift cards or accounts with available funds, attracting users with a cheap mentality.

According to the assessment, subjects can take advantage of the platform's refund policy, use stolen payment information to make transactions, then collect service fees and benefit from the difference. When the system detects a fraudulent transaction, users may have their purchased items revoked, account locked, or lose access. Personal information, bank card data and e-wallet data are also at risk of being leaked.

Using payment services of unknown origin can also cause users to unintentionally assist in the consumption of criminal assets. Depending on the nature and severity of the violation, acts related to property appropriation, illegal intrusion into information systems or money laundering may be handled according to legal regulations.

Hanoi City Police recommends that, to ensure safety, people should not use top-up or payment services through unofficial intermediary channels with unusually high discounts. Absolutely do not provide passwords, authentication codes and login information to others; Prioritize transactions via official payment gateways, banks or reputable e-wallets.

When detecting unusual transactions or signs of fraud, users need to quickly change their password, contact the bank to block the card when necessary, save evidence and report to the police.
