OpenSSL CCS Injection Attack
OpenSSL CCS Injection Attack is a security vulnerability in the OpenSSL library used for secure communication over the internet (e.g. HTTPS). This vulnerability allows an attacker to intercept and modify encrypted communication between two parties without their knowledge.
To understand this better, let’s imagine you are sending a secured message to your friend Alice using OpenSSL. You think that only you and Alice can read the message, but an attacker (let’s call him Bob) who is in the middle of the communication can intercept and modify the message before it reaches Alice.
This happens because of a flaw in the protocol that is used to negotiate the encryption between the two parties. The attacker (Bob) can exploit this vulnerability by injecting his own commands into the encrypted communication between you and Alice, making it seem like the commands came from you.
This attack is very dangerous because the attacker (Bob) can manipulate the communication between the two parties and steal sensitive information like passwords, credit card numbers, and other personal data.
To protect against this vulnerability, it is important to update to the latest version of OpenSSL and regularly check for security updates. It is also important to use additional security measures like two-factor authentication and strong passwords to further reduce the risk of attacks.
