The aim could be spying on individuals or groups to redirecting efforts, funds, resources, or attention.. An attacker cant decode the encrypted data sent between two computers communicating over an encrypted HTTPS connection. Transport layer security (TLS) is the successor protocol to secure sockets layer (SSL), which proved vulnerable and was finally deprecated in June 2015. where attackers intercept an existing conversation or data transfer, either by eavesdropping or by pretending to be a legitimate participant. In an SSL hijacking, the attacker intercepts all data passing between a server and the users computer. Email hijacking is when an attacker compromises an email account and silently gathers information by eavesdropping on email conversations. 1. Cybersecurity metrics and key performance indicators (KPIs) are an effective way to measure the success of your cybersecurity program. Both you and your colleague think the message is secure.
