(Here is the user manual of streamer 5. It's no exaggeration to say that streamer is Xiaorong's work. This tool can turn a person who can only click a mouse into a professional hacker. It can sniff POP3, FTP, HTTP, PROXY, FROM, SQL, SMTP, IPC, and other vulnerabilities. And it is used to design different cracking schemes for the vulnerabilities. Detailed comparison is recommended.)
