Banco Inter: Hacker allegedly leaks customer data

Some media outlets, such as the TecMundo, received a manifesto from an alleged hacker this Friday (04/05). In the released document, the person claims to have made an attack over the last few weeks invading the data of the Banco Inter.

In this alleged attack, which has not yet been confirmed by the bank itself, personal data of thousands of customers may have been exposed. In addition, employees and executives of the Banco Inter They weren't left out either. O Banco Inter is one of the largest in Brazil in its field. Its peculiarity is that it works completely digitally.

John's Attack

According to information released by TecMundo, they received an 18-page document last Tuesday. Thus, in this document, the hacker who introduces himself as John states in detail that he has gained access to user data from the Banco Inter. In addition, John also talks a little about his motivations for the attack.

 TecMundo itself reported that more than 81 names were actually leaked. However, hacker “John” claims that more than 300 names are involved. The encrypted file sent to some press vehicles and to the bank itself has more than 40 GB.

Among the data allegedly leaked are photos of checks, personal documents, transactions of various accounts, emails from users and employees. In addition, personal information, security keys and passwords of more than 100 thousand people.

The hacker's motivations

According to TecMundo, hacker John claims that Brazil's current banking system is deeply flawed. Thus, he is not prepared enough for a process of migration to the cloud system. His own attack is mere evidence of the loopholes that still exist in the system.

According to an excerpt from Hacker's manifesto, released by TecMundo, the decision on the conditions and limits that banks can adopt in Cloud Computing is close. However, what the hacker criticizes is the position of FINTECHs as the Banco Inter, who ignore this decision process and are already jumping headlong into this trend.

The hacker questions whether these tech financial services really question whether we are ready for that leap (to cloud storage). According to the information disclosed about the Hacker, he claims that benches as Banco Inter they did not wait for the final decision to take a stand.

Hacker's requirements for Banco Inter

In the manifesto released by TecMundo, the hacker states that he contacted the Banco Inter. “John” intends for the bank to fix the problem. However, for this to happen, the hacker demanded a certain amount as payment that was not revealed.

His threat was basically that if he didn't get a response within 15 days, he would make the case public. However, it is worth remembering that the Banco Inter acted in accordance with what the bailiffs indicate. One should not meet the demands of first-rate “data hijackers”.

establishing a protection

However, the main question among users at this moment is: what to do? Well, one of the main actions to be taken at first, according to experts, is to change any and all passwords you use. In addition, using different combinations that are not easily discovered with your personal data is essential.

That's because if your data was leaked, personal information such as birthday, family, CPF, RG and several other data that normally serve for passwords are also being accessed. So, changing your bank password (which was, for example, your birthday) for your mother's birthday is not a good idea.

Another good tactic is to create different passwords for each account you have. Thus, making it difficult to access all of them with just one piece of information. The attention, from the confirmed leak, must also be redoubled with documents that come to you as slips and miscellaneous communications. These could be fake.

More specifically about bank details, and not just personal ones, the person should immediately contact their bank branch. The most viable option here is to request the blocking of your accounts and cards so that fraudulent transactions are not carried out. With this block done, the user will need to call the bank to change the card number, password and other data.

Finally, about bank apps, it's important to be careful where and when you access them. Avoid public Wi-Fi networks as much as possible at these times. In addition, it is also recommended that you always keep an updated antivirus on your mobile device. This prevents malware from affecting your bank app.
