In March 2015, about 30% of network communication was protected by RC4. Through the attack, attackers can only use sniffing listening in a specific environment to restore plain text in encrypted information protected by RC4, this results in exposure of important sensitive information such as accounts, passwords, and credit card information, and session hijack
