900,000 bank account information sold on the black market, raising concerns over financial data security.

Recently, there have been reports that customer information from several domestic banks has been sold on the black market. It is reported that this data leak incident involves a wide range, including several large banks and Financial Institutions.

The leaked data can be mainly divided into two categories:

First, there are about 900,000 account information records from a large state-owned bank, priced at nearly $4,000. This data includes sensitive financial information such as customers' personal information, contact details, identification numbers, as well as deposit amounts and transaction records.

Secondly, there is a comprehensive data package involving multiple banks and enterprises. This includes 800,000 customer records from a certain city commercial bank, 460,000 credit card information from a joint-stock bank, 200,000 high-net-worth wealth management client data from a certain region, and 100,000 customer information from another city commercial bank. In addition, there is a large amount of data related to enterprises and individuals, such as detailed information on 12 million startup companies, personal profiles of 200,000 corporate executives, and 1.2 million VPN usage records.

Regarding the reasons for the bank data leak, industry experts analyze that there are mainly two possibilities: one is direct export from the backend database using technical means; the other is extraction by internal business personnel from the frontend system. From a technical perspective, the leakage of database information may be due to illegal copying by internal personnel or could be caused by external hacker attacks. The nature of this incident is likely due to insufficient security measures leading to the database leak.

This incident has once again raised concerns about the data security of Financial Institutions. As institutions that hold a large amount of sensitive personal information and financial data, banks have a significant responsibility in data protection. Ensuring the security of customer information while providing convenient financial services has become a major challenge faced by the current financial industry.

Experts suggest that financial institutions should strengthen internal management, improve data access permission controls, conduct regular security audits, and adopt advanced encryption technologies to protect sensitive information. At the same time, they also call on relevant regulatory authorities to intensify oversight of financial data security and establish stricter data protection standards and penalties.

For the vast majority of users, it is also necessary to enhance awareness of personal information protection. During daily financial activities, users should handle personal sensitive information with caution, regularly change passwords, and closely monitor their account dynamics in order to promptly detect and report suspicious activities.
