YONO SBI: Banking & Lifestyle | v1.23.36
How the Exploit Works
The exploit takes advantage of the unencrypted communication used by the YONO SBI: Banking & Lifestyle app. When a user interacts with the app, their data is transmitted in plaintext, allowing anyone who intercepts the communication to read and manipulate the data. This lack of encryption allows an attacker to execute a man-in-the-middle attack, where they can intercept and alter the communication between the user and the bank’s servers. This could lead to unauthorized transactions, leak of personal and financial information, and even compromise of the user’s banking account.
Conceptual Example Code
The following is a conceptual representation of the vulnerability being exploited. This is an oversimplified example and does not represent the actual complexity of a real-world attack.
GET /account_details HTTP/1.1
Host: yono.sbi
User-Agent: YONO/1.23.36
{ "account_number": "1234567890" }A malicious actor, having intercepted this unencrypted communication, could potentially manipulate or use the account details for unauthorized transactions.
Recommended Mitigations
Users are strongly advised to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can help detect and block suspicious activities, protecting users from potential attacks. Additionally, limiting the use of online banking on unsecured networks can minimize the risk of man-in-the-middle attacks.
